Throughout the drawings, identical reference characters and descriptions indicate similar, but not necessarily identical, elements. While the exemplary embodiments described herein are susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and will be described in detail herein. However, the exemplary embodiments described herein are not intended to be limited to the particular forms disclosed. Rather, the present disclosure covers all modifications, equivalents, and alternatives falling within the scope of the appended claims.
DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Rotating components of wearable devices, such as rotating arms on head-mounted displays, are typically limited in their use to house electronics and connectors. Even when rotating components house electronics, the electronics may be configured as closed systems that don't allow for the integration of other components. When the rotating component is a good location for one or more of these other components, system design may be compromised in locating them elsewhere.
As such, the present disclosure is generally directed to apparatuses, systems, and methods for improved architectures of rotatable housings of electronic devices. In one example, an electronic port may be mechanically coupled to the rotatable housing unit such that the electronic port is configured to rotate as the rotatable housing unit rotates. In this example, an audio component (e.g., a speaker) may also be coupled to the rotatable housing in a manner that enables it to rotate with the housing, and the housing be an arm of an artificial-reality device that has a head-mounted display. In some embodiments, such audio system architectures may include a sealed back volume through which subsystem components pass and/or are housed or enclosed. Such subsystem components may include flexible printed circuits (FPCs). Such an audio system architecture may enable the simultaneous rotation of the external connector, the audio system, and any other corresponding subsystems with a dynamically controllable service loop. Additionally, the system architecture may enable the external connector, the audio system, and any other corresponding subsystems to rotate for thousands of rotation cycles without experiencing degradation and/or failure in performance.
Features from any of the embodiments described herein may be used in combination with one another in accordance with the general principles described herein. These and other embodiments, features, and advantages will be more fully understood upon reading the following detailed description in conjunction with the accompanying drawings and claims.
The following will provide, with reference to FIGS. 1-6, detailed descriptions of systems and methods that include audio system architecture. The descriptions corresponding to FIGS. 7-15 will provide examples of various systems and devices implementing embodiments presented herein.
FIG. 1 shows an exemplary audio system assembly that may include and/or represent a rotatable housing unit, various subsystems, and external fasteners. For example, system 100 may include rotatable housing units 102 and 104. The term “rotatable housing unit,” as used herein, may generally refer to any type or form of device capable of rotating relative to another component and housing one or more devices. For example, a rotatable housing unit may extend from a primary housing unit as arm, a strap, and/or any other suitable type or form of extension. Furthermore, while FIG. 1 shows a system with two rotatable housing units, other systems may include a single rotatable housing unit or more than two rotatable housing units.
As shown in FIG. 1, first rotatable housing unit 102 may be coupled to a first side of a primary housing 120 and second rotatable housing unit 104 may be coupled to a second side of the primary housing that is opposite the first side of the head-mounted display. In some examples, rotatable housing unit 102 may be configured to be coupled to primary housing 120 such that rotatable housing unit 102 rotates relative to primary housing 120. Rotatable housing units 102 and 104 may also be configured to connect to a strap that holds the head-mounted display on a head of a user.
Rotatable housings units may be configured to hold one or more of various components and subsystems. For example, rotatable housing units may be configured to hold one or more electronic ports (e.g., universal serial bus (USB) ports, audio ports, etc.), one or more audio components (e.g., speakers), one or more wireless components, and/or any other suitable component. These components may be configured to transmit audio signals, data signals, video signals, and or power signals. Furthermore, any of these components may be configured to rotate as the rotatable housing unit rotates.
In FIG. 1, rotatable housing units 102 and 104 include a speaker (not shown), an audio jack (e.g., port 108), a USB jack (e.g., port 110), and an open cavity (e.g., open cavity 106). In some examples, open cavity 106 is dimensioned to guide sound waves from a speaker (not shown) toward an ear of a user. Open cavity 106 may also be configured to house other components and/or for passage of electronic connections between various subsystems.
As noted, an audio subsystem configured to be coupled to a rotatable housing may include a speaker, an audio jack or port, wiring, and or any other suitable audio component. In some examples, each component of the audio subsystem may be coupled to the rotatable housing unit in a manner than enables the components to rotate as the rotatable housing rotates.
A rotatable housing unit may rotate in any suitable direction relative to a primary housing. For example, as shown the example of FIG. 1, rotatable housing units 102 and 104 may rotate in a plane that at least substantially perpendicular to a plane of a display housed in primary housing 120. In other configurations, rotatable housing units may rotate in any other suitable plane relative to a primary housing and/or may be configured to rotate in more than one plane.
FIG. 2 shows exemplary design features of various subsystems including electronic ports and external fasteners (e.g., torque rings, O-rings, etc.) that may enable the rotatable housing unit to securely fasten to corresponding units (e.g., head-mounted displays). For example, audio system assembly 200 may include torque ring 220 and O-ring 230 to enable rotating housing unit 202 to securely fasten to the head-mounted display. In some examples, the external fasteners may enable the simultaneous rotation of electronic port 208 with rotating housing unit 202. The simultaneous rotation of the audio system assembly may prevent the various subsystems and wires that pass through the rotatable housing unit from damage and/or stress that could potentially result from independent rotations.
FIG. 3 shows exemplary illustrations of an audio system assembly including wiring positioned within an open cavity of the rotating housing unit. In some examples, the wiring may include and/or represent an FPC (e.g., a one-layer FPC, a two-layer FPC, a three-layer FPC, etc.) and/or any type of component capable of connecting to various subsystems and transmitting signals to other devices. For example, audio system assembly 300 may include FPC 340 passing through open cavity 306 of rotating housing unit 302. In some examples, the wiring may be configured to carry data associated with an augmented-reality displayed via the head-mounted display. In some examples, FPC 340 may have an independent connection with the USB-C FPC and/or the audio jack FPC (e.g., electronic port 108 and 110). The connection via FPC 340 may couple the electronic ports to the electric subsystem in the head-mounted display (e.g., a motherboard). In further examples, FPC 340 may include at least two layers of electronic traces where at least one of the traces may electrically couple the electronic subsystem to the head-mounted display. In some examples, a service loop of wiring for the subsystems may reside within and/or around open cavity 306. In some examples, the subsystems (e.g., FPC) may variably deform (e.g., expand and contract) within open cavity 306 during the rotation of the rotatable housing unit. Additionally, the FPCs may have variable thicknesses. In some examples, the wiring for the subsystems that reside within and/or around open cavity 306 may be sealed via a gasket. In some examples, sealing the wiring may include forming a compression molded gasket around the wiring. The wiring for the subsystems may also be sealed in any other suitable manner. In each of these examples, the sealed wiring may pass through open cavity 306 and rotate during the rotation of the rotatable housing unit.
FIG. 4 shows exemplary illustrations of additional fastening components for audio system assembly 400. In some examples, audio system assembly 400 may include torque ring 420 and O-ring 430. In some examples, torque ring 420 may be connected to the rotatable housing unit via screws 450, 451, and 452 that connect torque ring 420 to the rotatable housing unit. The connection of torque ring 420 and the rotatable housing unit may further enable the simultaneous rotation of audio system assembly 400 by preventing slippage and/or tolerance difference to ensure contact between the torque ring, O-rings, and the rotatable housing unit. Turning to FIG. 5, audio system assembly 500 may include crush ribs 560 positioned between the torque ring and the rotatable housing unit. For example, torque ring 420 and the rotatable housing unit may be screwed together and prevented from rotating independently by crush ribs 560.
FIG. 6 shows an exemplary method 600 for assembling an audio system, according to some embodiments. As illustrated in FIG. 6, step 610 may include coupling at least one electronic port to a rotating housing unit. For example, as illustrated in FIG. 1, electronic port 108 and 110 may be coupled to rotating housing unit 102 and 104. In some examples, further comprising coupling an audio subsystem to the rotatable housing unit such that the audio subsystem is configured to rotate as the rotatable housing unit rotates. In some examples, methods described herein may include coupling an audio subsystem to the rotatable housing unit such that the audio subsystem is configured to rotate as the rotatable housing unit rotates. For example, as illustrated in FIG. 1, electronic port 108 (e.g., audio jack FPC) may be coupled to rotating housing unit 102 such that electronic port 108 is configured to rotate as rotatable housing unit 102 rotates.
Step 620 may include coupling a rotatable housing unit configured to a head-mounted display such that the rotatable housing is configured to rotate relative to the head-mounted display. For example, as illustrated in FIG. 1, rotating housing unit 102 may be configured to rotate relative to the head-mounted display.
Step 630 may include mechanically coupling the electronic port to the rotatable housing unit such that the electronic port is configured to rotate as the rotatable housing unit rotates. For example, as illustrated in FIG. 1, electronic port 108 may be mechanically coupled to rotating housing unit 102 such that electronic port 108 is configured to rotate as rotatable housing unit 102 rotates. In some examples, the methods described herein may include positioning wiring within a cavity of the rotatable housing unit. For example, as illustrated in FIG. 3, wiring (e.g., FPC 340) may be positioned within open cavity 306 of rotating housing unit 302. In further examples, the methods described herein may include electrically coupling the wiring to the electronic port and the electronic subsystem, wherein the wiring is configured to deform as the housing unit rotates. For example, as illustrated in FIG. 1, the wiring may be electrically coupled to electronic port 108 and the electronic subsystem, wherein the wiring is configured to deform as rotating housing unit 102 rotates. In other examples, the wiring may include a flexible printed circuit. For example, as illustrated in FIG. 3, the wiring may include an FPC 340.
Step 640 may include electrically coupling the electric port to an electronic subsystem of the head-mounted display. For example, as illustrated in FIG. 1, electric port 108 may be electrically coupled to an electronic subsystem of the head-mounted display.
As shown, the systems and methods presented herein may enable designs that are more effective, effective, flexible, and/or user-friendly by enabling components of a wearable system to rotate with a housing that contains the components. The systems described herein may also enable multiple components to be included in a single housing, allowing for more design flexibility and the ability to make simpler designs that are more durable in their ability to accommodate rotation.

Embodiments of the present disclosure may include or be implemented in conjunction with various types of Artificial-Reality (AR) systems. AR may be any superimposed functionality and/or sensory-detectable content presented by an artificial-reality system within a user's physical surroundings. In other words, AR is a form of reality that has been adjusted in some manner before presentation to a user. AR can include and/or represent virtual reality (VR), augmented reality, mixed AR (MAR), or some combination and/or variation of these types of realities. Similarly, AR environments may include VR environments (including non-immersive, semi-immersive, and fully immersive VR environments), augmented-reality environments (including marker-based augmented-reality environments, markerless augmented-reality environments, location-based augmented-reality environments, and projection-based augmented-reality environments), hybrid-reality environments, and/or any other type or form of mixed- or alternative-reality environments.
AR content may include completely computer-generated content or computer-generated content combined with captured (e.g., real-world) content. Such AR content may include video, audio, haptic feedback, or some combination thereof, any of which may be presented in a single channel or in multiple channels (such as stereo video that produces a three-dimensional (3D) effect to the viewer). Additionally, in some embodiments, AR may also be associated with applications, products, accessories, services, or some combination thereof, that are used to, for example, create content in an artificial reality and/or are otherwise used in (e.g., to perform activities in) an artificial reality.
AR systems may be implemented in a variety of different form factors and configurations. Some AR systems may be designed to work without near-eye displays (NEDs). Other AR systems may include a NED that also provides visibility into the real world (such as, e.g., augmented-reality system 1300 in FIG. 13) or that visually immerses a user in an artificial reality (such as, e.g., virtual-reality system 1400 in FIGS. 14A and 14B). While some AR devices may be self-contained systems, other AR devices may communicate and/or coordinate with external devices to provide an AR experience to a user. Examples of such external devices include handheld controllers, mobile devices, desktop computers, devices worn by a user, devices worn by one or more other users, and/or any other suitable external system.
FIGS. 7-10B illustrate example artificial-reality (AR) systems in accordance with some embodiments. FIG. 7 shows a first AR system 700 and first example user interactions using a wrist-wearable device 702, a head-wearable device (e.g., AR glasses 1300), and/or a handheld intermediary processing device (HIPD) 706. FIG. 8 shows a second AR system 800 and second example user interactions using a wrist-wearable device 802, AR glasses 804, and/or an HIPD 806. FIGS. 9A and 9B show a third AR system 900 and third example user 908 interactions using a wrist-wearable device 902, a head-wearable device (e.g., VR headset 950), and/or an HIPD 906. FIGS. 10A and 10B show a fourth AR system 1000 and fourth example user 1008 interactions using a wrist-wearable device 1030, VR headset 1020, and/or a haptic device 1060 (e.g., wearable gloves).
A wrist-wearable device 1100, which can be used for wrist-wearable device 702, 802, 902, 1030, and one or more of its components, are described below in reference to FIGS. 11 and 12; head-wearable devices 1300 and 1400, which can respectively be used for AR glasses 704, 804 or VR headset 950, 1020, and their one or more components are described below in reference to FIGS. 13-15.
Referring to FIG. 7, wrist-wearable device 702, AR glasses 704, and/or HIPD 706 can communicatively couple via a network 725 (e.g., cellular, near field, Wi-Fi, personal area network, wireless LAN, etc.). Additionally, wrist-wearable device 702, AR glasses 704, and/or HIPD 706 can also communicatively couple with one or more servers 730, computers 740 (e.g., laptops, computers, etc.), mobile devices 750 (e.g., smartphones, tablets, etc.), and/or other electronic devices via network 725 (e.g., cellular, near field, Wi-Fi, personal area network, wireless LAN, etc.).
In FIG. 7, a user 708 is shown wearing wrist-wearable device 702 and AR glasses 704 and having HIPD 706 on their desk. The wrist-wearable device 702, AR glasses 704, and HIPD 706 facilitate user interaction with an AR environment. In particular, as shown by first AR system 700, wrist-wearable device 702, AR glasses 704, and/or HIPD 706 cause presentation of one or more avatars 710, digital representations of contacts 712, and virtual objects 714. As discussed below, user 708 can interact with one or more avatars 710, digital representations of contacts 712, and virtual objects 714 via wrist-wearable device 702, AR glasses 704, and/or HIPD 706.
User 708 can use any of wrist-wearable device 702, AR glasses 704, and/or HIPD 706 to provide user inputs. For example, user 708 can perform one or more hand gestures that are detected by wrist-wearable device 702 (e.g., using one or more EMG sensors and/or IMUs, described below in reference to FIGS. 11 and 12) and/or AR glasses 704 (e.g., using one or more image sensor or camera, described below in reference to FIGS. 13-10) to provide a user input. Alternatively, or additionally, user 708 can provide a user input via one or more touch surfaces of wrist-wearable device 702, AR glasses 704, HIPD 706, and/or voice commands captured by a microphone of wrist-wearable device 702, AR glasses 704, and/or HIPD 706. In some embodiments, wrist-wearable device 702, AR glasses 704, and/or HIPD 706 include a digital assistant to help user 708 in providing a user input (e.g., completing a sequence of operations, suggesting different operations or commands, providing reminders, confirming a command, etc.). In some embodiments, user 708 can provide a user input via one or more facial gestures and/or facial expressions. For example, cameras of wrist-wearable device 702, AR glasses 704, and/or HIPD 706 can track eyes of user 708 for navigating a user interface.
Wrist-wearable device 702, AR glasses 704, and/or HIPD 706 can operate alone or in conjunction to allow user 708 to interact with the AR environment. In some embodiments, HIPD 706 is configured to operate as a central hub or control center for the wrist-wearable device 702, AR glasses 704, and/or another communicatively coupled device. For example, user 708 can provide an input to interact with the AR environment at any of wrist-wearable device 702, AR glasses 704, and/or HIPD 706, and HIPD 706 can identify one or more back-end and front-end tasks to cause the performance of the requested interaction and distribute instructions to cause the performance of the one or more back-end and front-end tasks at wrist-wearable device 702, AR glasses 704, and/or HIPD 706. In some embodiments, a back-end task is a background processing task that is not perceptible by the user (e.g., rendering content, decompression, compression, etc.), and a front-end task is a user-facing task that is perceptible to the user (e.g., presenting information to the user, providing feedback to the user, etc.). As described below, HIPD 706 can perform the back-end tasks and provide wrist-wearable device 702 and/or AR glasses 704 operational data corresponding to the performed back-end tasks such that wrist-wearable device 702 and/or AR glasses 704 can perform the front-end tasks. In this way, HIPD 706, which has more computational resources and greater thermal headroom than wrist-wearable device 702 and/or AR glasses 704, performs computationally intensive tasks and reduces the computer resource utilization and/or power usage of wrist-wearable device 702 and/or AR glasses 704.
In the example shown by first AR system 700, HIPD 706 identifies one or more back-end tasks and front-end tasks associated with a user request to initiate an AR video call with one or more other users (represented by avatar 710 and the digital representation of contact 712) and distributes instructions to cause the performance of the one or more back-end tasks and front-end tasks. In particular, HIPD 706 performs back-end tasks for processing and/or rendering image data (and other data) associated with the AR video call and provides operational data associated with the performed back-end tasks to AR glasses 704 such that the AR glasses 704 perform front-end tasks for presenting the AR video call (e.g., presenting avatar 710 and digital representation of contact 712).
In some embodiments, HIPD 706 can operate as a focal or anchor point for causing the presentation of information. This allows user 708 to be generally aware of where information is presented. For example, as shown in first AR system 700, avatar 710 and the digital representation of contact 712 are presented above HIPD 706. In particular, HIPD 706 and AR glasses 704 operate in conjunction to determine a location for presenting avatar 710 and the digital representation of contact 712. In some embodiments, information can be presented a predetermined distance from HIPD 706 (e.g., within 5 meters). For example, as shown in first AR system 700, virtual object 714 is presented on the desk some distance from HIPD 706. Similar to the above example, HIPD 706 and AR glasses 704 can operate in conjunction to determine a location for presenting virtual object 714. Alternatively, in some embodiments, presentation of information is not bound by HIPD 706. More specifically, avatar 710, digital representation of contact 712, and virtual object 714 do not have to be presented within a predetermined distance of HIPD 706.
User inputs provided at wrist-wearable device 702, AR glasses 704, and/or HIPD 706 are coordinated such that the user can use any device to initiate, continue, and/or complete an operation. For example, user 708 can provide a user input to AR glasses 704 to cause AR glasses 704 to present virtual object 714 and, while virtual object 714 is presented by AR glasses 704, user 708 can provide one or more hand gestures via wrist-wearable device 702 to interact and/or manipulate virtual object 714.
FIG. 8 shows a user 808 wearing a wrist-wearable device 802 and AR glasses 804, and holding an HIPD 806. In second AR system 800, the wrist-wearable device 802, AR glasses 804, and/or HIPD 806 are used to receive and/or provide one or more messages to a contact of user 808. In particular, wrist-wearable device 802, AR glasses 804, and/or HIPD 806 detect and coordinate one or more user inputs to initiate a messaging application and prepare a response to a received message via the messaging application.
In some embodiments, user 808 initiates, via a user input, an application on wrist-wearable device 802, AR glasses 804, and/or HIPD 806 that causes the application to initiate on at least one device. For example, in second AR system 800, user 808 performs a hand gesture associated with a command for initiating a messaging application (represented by messaging user interface 816), wrist-wearable device 802 detects the hand gesture and, based on a determination that user 808 is wearing AR glasses 804, causes AR glasses 804 to present a messaging user interface 816 of the messaging application. AR glasses 804 can present messaging user interface 816 to user 808 via its display (e.g., as shown by a field of view 818 of user 808). In some embodiments, the application is initiated and executed on the device (e.g., wrist-wearable device 802, AR glasses 804, and/or HIPD 806) that detects the user input to initiate the application, and the device provides another device operational data to cause the presentation of the messaging application. For example, wrist-wearable device 802 can detect the user input to initiate a messaging application, initiate and run the messaging application, and provide operational data to AR glasses 804 and/or HIPD 806 to cause presentation of the messaging application. Alternatively, the application can be initiated and executed at a device other than the device that detected the user input. For example, wrist-wearable device 802 can detect the hand gesture associated with initiating the messaging application and cause HIPD 806 to run the messaging application and coordinate the presentation of the messaging application.
Further, user 808 can provide a user input provided at wrist-wearable device 802, AR glasses 804, and/or HIPD 806 to continue and/or complete an operation initiated at another device. For example, after initiating the messaging application via wrist-wearable device 802 and while AR glasses 804 present messaging user interface 816, user 808 can provide an input at HIPD 806 to prepare a response (e.g., shown by the swipe gesture performed on HIPD 806). Gestures performed by user 808 on HIPD 806 can be provided and/or displayed on another device. For example, a swipe gestured performed on HIPD 806 is displayed on a virtual keyboard of messaging user interface 816 displayed by AR glasses 804.
In some embodiments, wrist-wearable device 802, AR glasses 804, HIPD 806, and/or any other communicatively coupled device can present one or more notifications to user 808. The notification can be an indication of a new message, an incoming call, an application update, a status update, etc. User 808 can select the notification via wrist-wearable device 802, AR glasses 804, and/or HIPD 806 and can cause presentation of an application or operation associated with the notification on at least one device. For example, user 808 can receive a notification that a message was received at wrist-wearable device 802, AR glasses 804, HIPD 806, and/or any other communicatively coupled device and can then provide a user input at wrist-wearable device 802, AR glasses 804, and/or HIPD 806 to review the notification, and the device detecting the user input can cause an application associated with the notification to be initiated and/or presented at wrist-wearable device 802, AR glasses 804, and/or HIPD 806.
While the above example describes coordinated inputs used to interact with a messaging application, user inputs can be coordinated to interact with any number of applications including, but not limited to, gaming applications, social media applications, camera applications, web-based applications, financial applications, etc. For example, AR glasses 804 can present to user 808 game application data, and HIPD 806 can be used as a controller to provide inputs to the game. Similarly, user 808 can use wrist-wearable device 802 to initiate a camera of AR glasses 804, and user 308 can use wrist-wearable device 802, AR glasses 804, and/or HIPD 806 to manipulate the image capture (e.g., zoom in or out, apply filters, etc.) and capture image data.
Users may interact with the devices disclosed herein in a variety of ways. For example, as shown in FIGS. 9A and 9B, a user 908 may interact with an AR system 900 by donning a VR headset 950 while holding HIPD 906 and wearing wrist-wearable device 902. In this example, AR system 900 may enable a user to interact with a game 910 by swiping their arm. One or more of VR headset 950, HIPD 906, and wrist-wearable device 902 may detect this gesture and, in response, may display a sword strike in game 910. Similarly, in FIGS. 10A and 10B, a user 1008 may interact with an AR system 1000 by donning a VR headset 1020 while wearing haptic device 1060 and wrist-wearable device 1030. In this example, AR system 1000 may enable a user to interact with a game 1010 by swiping their arm. One or more of VR headset 1020, haptic device 1060, and wrist-wearable device 1030 may detect this gesture and, in response, may display a spell being cast in game 910.

FIGS. 11 and 12 illustrate an example wrist-wearable device 1100 and an example computer system 1200, in accordance with some embodiments. Wrist-wearable device 1100 is an instance of wearable device 702 described in FIG. 7 herein, such that the wearable device 702 should be understood to have the features of the wrist-wearable device 1100 and vice versa. FIG. 12 illustrates components of the wrist-wearable device 1100, which can be used individually or in combination, including combinations that include other electronic devices and/or electronic components.
FIG. 11 shows a wearable band 1110 and a watch body 1120 (or capsule) being coupled, as discussed below, to form wrist-wearable device 1100. Wrist-wearable device 1100 can perform various functions and/or operations associated with navigating through user interfaces and selectively opening applications as well as the functions and/or operations described above with reference to FIGS. 7-10B.
As will be described in more detail below, operations executed by wrist-wearable device 1100 can include (i) presenting content to a user (e.g., displaying visual content via a display 1105), (ii) detecting (e.g., sensing) user input (e.g., sensing a touch on peripheral button 1123 and/or at a touch screen of the display 1105, a hand gesture detected by sensors (e.g., biopotential sensors)), (iii) sensing biometric data (e.g., neuromuscular signals, heart rate, temperature, sleep, etc.) via one or more sensors 1113, messaging (e.g., text, speech, video, etc.); image capture via one or more imaging devices or cameras 1125, wireless communications (e.g., cellular, near field, Wi-Fi, personal area network, etc.), location determination, financial transactions, providing haptic feedback, providing alarms, providing notifications, providing biometric authentication, providing health monitoring, providing sleep monitoring, etc.
The above-example functions can be executed independently in watch body 1120, independently in wearable band 1110, and/or via an electronic communication between watch body 1120 and wearable band 1110. In some embodiments, functions can be executed on wrist-wearable device 1100 while an AR environment is being presented (e.g., via one of AR systems 700 to 1000). The wearable devices described herein can also be used with other types of AR environments.
Wearable band 1110 can be configured to be worn by a user such that an inner surface of a wearable structure 1111 of wearable band 1110 is in contact with the user's skin. In this example, when worn by a user, sensors 1113 may contact the user's skin. In some examples, one or more of sensors 1113 can sense biometric data such as a user's heart rate, a saturated oxygen level, temperature, sweat level, neuromuscular signals, or a combination thereof. One or more of sensors 1113 can also sense data about a user's environment including a user's motion, altitude, location, orientation, gait, acceleration, position, or a combination thereof. In some embodiment, one or more of sensors 1113 can be configured to track a position and/or motion of wearable band 1110. One or more of sensors 1113 can include any of the sensors defined above and/or discussed below with respect to FIG. 11.
One or more of sensors 1113 can be distributed on an inside and/or an outside surface of wearable band 1110. In some embodiments, one or more of sensors 1113 are uniformly spaced along wearable band 1110. Alternatively, in some embodiments, one or more of sensors 1113 are positioned at distinct points along wearable band 1110. As shown in FIG. 11, one or more of sensors 1113 can be the same or distinct. For example, in some embodiments, one or more of sensors 1113 can be shaped as a pill (e.g., sensor 1113a), an oval, a circle a square, an oblong (e.g., sensor 1113c) and/or any other shape that maintains contact with the user's skin (e.g., such that neuromuscular signal and/or other biometric data can be accurately measured at the user's skin). In some embodiments, one or more sensors of 1113 are aligned to form pairs of sensors (e.g., for sensing neuromuscular signals based on differential sensing within each respective sensor). For example, sensor 1113b may be aligned with an adjacent sensor to form sensor pair 1114a and sensor 1113d may be aligned with an adjacent sensor to form sensor pair 1114b. In some embodiments, wearable band 1110 does not have a sensor pair. Alternatively, in some embodiments, wearable band 1110 has a predetermined number of sensor pairs (one pair of sensors, three pairs of sensors, four pairs of sensors, six pairs of sensors, sixteen pairs of sensors, etc.).
Wearable band 1110 can include any suitable number of sensors 1113. In some embodiments, the number and arrangement of sensors 1113 depends on the particular application for which wearable band 1110 is used. For instance, wearable band 1110 can be configured as an armband, wristband, or chest-band that include a plurality of sensors 1113 with different number of sensors 1113, a variety of types of individual sensors with the plurality of sensors 1113, and different arrangements for each use case, such as medical use cases as compared to gaming or general day-to-day use cases.
In accordance with some embodiments, wearable band 1110 further includes an electrical ground electrode and a shielding electrode. The electrical ground and shielding electrodes, like the sensors 1113, can be distributed on the inside surface of the wearable band 1110 such that they contact a portion of the user's skin. For example, the electrical ground and shielding electrodes can be at an inside surface of a coupling mechanism 1116 or an inside surface of a wearable structure 1111. The electrical ground and shielding electrodes can be formed and/or use the same components as sensors 1113. In some embodiments, wearable band 1110 includes more than one electrical ground electrode and more than one shielding electrode.
Sensors 1113 can be formed as part of wearable structure 1111 of wearable band 1110. In some embodiments, sensors 1113 are flush or substantially flush with wearable structure 1111 such that they do not extend beyond the surface of wearable structure 1111. While flush with wearable structure 1111, sensors 1113 are still configured to contact the user's skin (e.g., via a skin-contacting surface). Alternatively, in some embodiments, sensors 1113 extend beyond wearable structure 1111 a predetermined distance (e.g., 0.1-2 mm) to make contact and depress into the user's skin. In some embodiment, sensors 1113 are coupled to an actuator (not shown) configured to adjust an extension height (e.g., a distance from the surface of wearable structure 1111) of sensors 1113 such that sensors 1113 make contact and depress into the user's skin. In some embodiments, the actuators adjust the extension height between 0.01 mm-1.2 mm. This may allow a the user to customize the positioning of sensors 1113 to improve the overall comfort of the wearable band 1110 when worn while still allowing sensors 1113 to contact the user's skin. In some embodiments, sensors 1113 are indistinguishable from wearable structure 1111 when worn by the user.
Wearable structure 1111 can be formed of an elastic material, elastomers, etc., configured to be stretched and fitted to be worn by the user. In some embodiments, wearable structure 1111 is a textile or woven fabric. As described above, sensors 1113 can be formed as part of a wearable structure 1111. For example, sensors 1113 can be molded into the wearable structure 1111, be integrated into a woven fabric (e.g., sensors 1113 can be sewn into the fabric and mimic the pliability of fabric and can and/or be constructed from a series woven strands of fabric).
Wearable structure 1111 can include flexible electronic connectors that interconnect sensors 1113, the electronic circuitry, and/or other electronic components (described below in reference to FIG. 12) that are enclosed in wearable band 1110. In some embodiments, the flexible electronic connectors are configured to interconnect sensors 1113, the electronic circuitry, and/or other electronic components of wearable band 1110 with respective sensors and/or other electronic components of another electronic device (e.g., watch body 1120). The flexible electronic connectors are configured to move with wearable structure 1111 such that the user adjustment to wearable structure 1111 (e.g., resizing, pulling, folding, etc.) does not stress or strain the electrical coupling of components of wearable band 1110.
As described above, wearable band 1110 is configured to be worn by a user. In particular, wearable band 1110 can be shaped or otherwise manipulated to be worn by a user. For example, wearable band 1110 can be shaped to have a substantially circular shape such that it can be configured to be worn on the user's lower arm or wrist. Alternatively, wearable band 1110 can be shaped to be worn on another body part of the user, such as the user's upper arm (e.g., around a bicep), forearm, chest, legs, etc. Wearable band 1110 can include a retaining mechanism 1112 (e.g., a buckle, a hook and loop fastener, etc.) for securing wearable band 1110 to the user's wrist or other body part. While wearable band 1110 is worn by the user, sensors 1113 sense data (referred to as sensor data) from the user's skin. In some examples, sensors 1113 of wearable band 1110 obtain (e.g., sense and record) neuromuscular signals.
The sensed data (e.g., sensed neuromuscular signals) can be used to detect and/or determine the user's intention to perform certain motor actions. In some examples, sensors 1113 may sense and record neuromuscular signals from the user as the user performs muscular activations (e.g., movements, gestures, etc.). The detected and/or determined motor actions (e.g., phalange (or digit) movements, wrist movements, hand movements, and/or other muscle intentions) can be used to determine control commands or control information (instructions to perform certain commands after the data is sensed) for causing a computing device to perform one or more input commands. For example, the sensed neuromuscular signals can be used to control certain user interfaces displayed on display 1105 of wrist-wearable device 1100 and/or can be transmitted to a device responsible for rendering an artificial-reality environment (e.g., a head-mounted display) to perform an action in an associated artificial-reality environment, such as to control the motion of a virtual device displayed to the user. The muscular activations performed by the user can include static gestures, such as placing the user's hand palm down on a table, dynamic gestures, such as grasping a physical or virtual object, and covert gestures that are imperceptible to another person, such as slightly tensing a joint by co-contracting opposing muscles or using sub-muscular activations. The muscular activations performed by the user can include symbolic gestures (e.g., gestures mapped to other gestures, interactions, or commands, for example, based on a gesture vocabulary that specifies the mapping of gestures to commands).
The sensor data sensed by sensors 1113 can be used to provide a user with an enhanced interaction with a physical object (e.g., devices communicatively coupled with wearable band 1110) and/or a virtual object in an artificial-reality application generated by an artificial-reality system (e.g., user interface objects presented on the display 1105, or another computing device (e.g., a smartphone)).
In some embodiments, wearable band 1110 includes one or more haptic devices 1246 (e.g., a vibratory haptic actuator) that are configured to provide haptic feedback (e.g., a cutaneous and/or kinesthetic sensation, etc.) to the user's skin. Sensors 1113 and/or haptic devices 1246 (shown in FIG. 12) can be configured to operate in conjunction with multiple applications including, without limitation, health monitoring, social media, games, and artificial reality (e.g., the applications associated with artificial reality).
Wearable band 1110 can also include coupling mechanism 1116 for detachably coupling a capsule (e.g., a computing unit) or watch body 1120 (via a coupling surface of the watch body 1120) to wearable band 1110. For example, a cradle or a shape of coupling mechanism 1116 can correspond to shape of watch body 1120 of wrist-wearable device 1100. In particular, coupling mechanism 1116 can be configured to receive a coupling surface proximate to the bottom side of watch body 1120 (e.g., a side opposite to a front side of watch body 1120 where display 1105 is located), such that a user can push watch body 1120 downward into coupling mechanism 1116 to attach watch body 1120 to coupling mechanism 1116. In some embodiments, coupling mechanism 1116 can be configured to receive a top side of the watch body 1120 (e.g., a side proximate to the front side of watch body 1120 where display 1105 is located) that is pushed upward into the cradle, as opposed to being pushed downward into coupling mechanism 1116. In some embodiments, coupling mechanism 1116 is an integrated component of wearable band 1110 such that wearable band 1110 and coupling mechanism 1116 are a single unitary structure. In some embodiments, coupling mechanism 1116 is a type of frame or shell that allows watch body 1120 coupling surface to be retained within or on wearable band 1110 coupling mechanism 1116 (e.g., a cradle, a tracker band, a support base, a clasp, etc.).
Coupling mechanism 1116 can allow for watch body 1120 to be detachably coupled to the wearable band 1110 through a friction fit, magnetic coupling, a rotation-based connector, a shear-pin coupler, a retention spring, one or more magnets, a clip, a pin shaft, a hook and loop fastener, or a combination thereof. A user can perform any type of motion to couple the watch body 1120 to wearable band 1110 and to decouple the watch body 1120 from the wearable band 1110. For example, a user can twist, slide, turn, push, pull, or rotate watch body 1120 relative to wearable band 1110, or a combination thereof, to attach watch body 1120 to wearable band 1110 and to detach watch body 1120 from wearable band 1110. Alternatively, as discussed below, in some embodiments, the watch body 1120 can be decoupled from the wearable band 1110 by actuation of a release mechanism 1129.
Wearable band 1110 can be coupled with watch body 1120 to increase the functionality of wearable band 1110 (e.g., converting wearable band 1110 into wrist-wearable device 1100, adding an additional computing unit and/or battery to increase computational resources and/or a battery life of wearable band 1110, adding additional sensors to improve sensed data, etc.). As described above, wearable band 1110 and coupling mechanism 1116 are configured to operate independently (e.g., execute functions independently) from watch body 1120. For example, coupling mechanism 1116 can include one or more sensors 1113 that contact a user's skin when wearable band 1110 is worn by the user, with or without watch body 1120 and can provide sensor data for determining control commands.
A user can detach watch body 1120 from wearable band 1110 to reduce the encumbrance of wrist-wearable device 1100 to the user. For embodiments in which watch body 1120 is removable, watch body 1120 can be referred to as a removable structure, such that in these embodiments wrist-wearable device 1100 includes a wearable portion (e.g., wearable band 1110) and a removable structure (e.g., watch body 1120).
Turning to watch body 1120, in some examples watch body 1120 can have a substantially rectangular or circular shape. Watch body 1120 is configured to be worn by the user on their wrist or on another body part. More specifically, watch body 1120 is sized to be easily carried by the user, attached on a portion of the user's clothing, and/or coupled to wearable band 1110 (forming the wrist-wearable device 1100). As described above, watch body 1120 can have a shape corresponding to coupling mechanism 1116 of wearable band 1110. In some embodiments, watch body 1120 includes a single release mechanism 1129 or multiple release mechanisms (e.g., two release mechanisms 1129 positioned on opposing sides of watch body 1120, such as spring-loaded buttons) for decoupling watch body 1120 from wearable band 1110. Release mechanism 1129 can include, without limitation, a button, a knob, a plunger, a handle, a lever, a fastener, a clasp, a dial, a latch, or a combination thereof.
A user can actuate release mechanism 1129 by pushing, turning, lifting, depressing, shifting, or performing other actions on release mechanism 1129. Actuation of release mechanism 1129 can release (e.g., decouple) watch body 1120 from coupling mechanism 1116 of wearable band 1110, allowing the user to use watch body 1120 independently from wearable band 1110 and vice versa. For example, decoupling watch body 1120 from wearable band 1110 can allow a user to capture images using rear-facing camera 1125b. Although release mechanism 1129 is shown positioned at a corner of watch body 1120, release mechanism 1129 can be positioned anywhere on watch body 1120 that is convenient for the user to actuate. In addition, in some embodiments, wearable band 1110 can also include a respective release mechanism for decoupling watch body 1120 from coupling mechanism 1116. In some embodiments, release mechanism 1129 is optional and watch body 1120 can be decoupled from coupling mechanism 1116 as described above (e.g., via twisting, rotating, etc.).
Watch body 1120 can include one or more peripheral buttons 1123 and 1127 for performing various operations at watch body 1120. For example, peripheral buttons 1123 and 1127 can be used to turn on or wake (e.g., transition from a sleep state to an active state) display 1105, unlock watch body 1120, increase or decrease a volume, increase or decrease a brightness, interact with one or more applications, interact with one or more user interfaces, etc. Additionally or alternatively, in some embodiments, display 1105 operates as a touch screen and allows the user to provide one or more inputs for interacting with watch body 1120.
In some embodiments, watch body 1120 includes one or more sensors 1121. Sensors 1121 of watch body 1120 can be the same or distinct from sensors 1113 of wearable band 1110. Sensors 1121 of watch body 1120 can be distributed on an inside and/or an outside surface of watch body 1120. In some embodiments, sensors 1121 are configured to contact a user's skin when watch body 1120 is worn by the user. For example, sensors 1121 can be placed on the bottom side of watch body 1120 and coupling mechanism 1116 can be a cradle with an opening that allows the bottom side of watch body 1120 to directly contact the user's skin. Alternatively, in some embodiments, watch body 1120 does not include sensors that are configured to contact the user's skin (e.g., including sensors internal and/or external to the watch body 1120 that are configured to sense data of watch body 1120 and the surrounding environment). In some embodiments, sensors 1121 are configured to track a position and/or motion of watch body 1120.
Watch body 1120 and wearable band 1110 can share data using a wired communication method (e.g., a Universal Asynchronous Receiver/Transmitter (UART), a USB transceiver, etc.) and/or a wireless communication method (e.g., near field communication, Bluetooth, etc.). For example, watch body 1120 and wearable band 1110 can share data sensed by sensors 1113 and 1121, as well as application and device specific information (e.g., active and/or available applications, output devices (e.g., displays, speakers, etc.), input devices (e.g., touch screens, microphones, imaging sensors, etc.).
In some embodiments, watch body 1120 can include, without limitation, a front-facing camera 1125a and/or a rear-facing camera 1125b, sensors 1121 (e.g., a biometric sensor, an IMU, a heart rate sensor, a saturated oxygen sensor, a neuromuscular signal sensor, an altimeter sensor, a temperature sensor, a bioimpedance sensor, a pedometer sensor, an optical sensor (e.g., imaging sensor 1263), a touch sensor, a sweat sensor, etc.). In some embodiments, watch body 1120 can include one or more haptic devices 1276 (e.g., a vibratory haptic actuator) that is configured to provide haptic feedback (e.g., a cutaneous and/or kinesthetic sensation, etc.) to the user. Sensors 1221 and/or haptic device 1276 can also be configured to operate in conjunction with multiple applications including, without limitation, health monitoring applications, social media applications, game applications, and artificial reality applications (e.g., the applications associated with artificial reality).
As described above, watch body 1120 and wearable band 1110, when coupled, can form wrist-wearable device 1100. When coupled, watch body 1120 and wearable band 1110 may operate as a single device to execute functions (operations, detections, communications, etc.) described herein. In some embodiments, each device may be provided with particular instructions for performing the one or more operations of wrist-wearable device 1100. For example, in accordance with a determination that watch body 1120 does not include neuromuscular signal sensors, wearable band 1110 can include alternative instructions for performing associated instructions (e.g., providing sensed neuromuscular signal data to watch body 1120 via a different electronic device). Operations of wrist-wearable device 1100 can be performed by watch body 1120 alone or in conjunction with wearable band 1110 (e.g., via respective processors and/or hardware components) and vice versa. In some embodiments, operations of wrist-wearable device 1100, watch body 1120, and/or wearable band 1110 can be performed in conjunction with one or more processors and/or hardware components.
As described below with reference to the block diagram of FIG. 12, wearable band 1110 and/or watch body 1120 can each include independent resources required to independently execute functions. For example, wearable band 1110 and/or watch body 1120 can each include a power source (e.g., a battery), a memory, data storage, a processor (e.g., a central processing unit (CPU)), communications, a light source, and/or input/output devices.
FIG. 12 shows block diagrams of a computing system 1230 corresponding to wearable band 1110 and a computing system 1260 corresponding to watch body 1120 according to some embodiments. Computing system 1200 of wrist-wearable device 1100 may include a combination of components of wearable band computing system 1230 and watch body computing system 1260, in accordance with some embodiments.
Watch body 1120 and/or wearable band 1110 can include one or more components shown in watch body computing system 1260. In some embodiments, a single integrated circuit may include all or a substantial portion of the components of watch body computing system 1260 included in a single integrated circuit. Alternatively, in some embodiments, components of the watch body computing system 1260 may be included in a plurality of integrated circuits that are communicatively coupled. In some embodiments, watch body computing system 1260 may be configured to couple (e.g., via a wired or wireless connection) with wearable band computing system 1230, which may allow the computing systems to share components, distribute tasks, and/or perform other operations described herein (individually or as a single device).
Watch body computing system 1260 can include one or more processors 1279, a controller 1277, a peripherals interface 1261, a power system 1295, and memory (e.g., a memory 1280).
Power system 1295 can include a charger input 1296, a power-management integrated circuit (PMIC) 1297, and a battery 1298. In some embodiments, a watch body 1120 and a wearable band 1110 can have respective batteries (e.g., battery 1298 and 1259) and can share power with each other. Watch body 1120 and wearable band 1110 can receive a charge using a variety of techniques. In some embodiments, watch body 1120 and wearable band 1110 can use a wired charging assembly (e.g., power cords) to receive the charge. Alternatively, or in addition, watch body 1120 and/or wearable band 1110 can be configured for wireless charging. For example, a portable charging device can be designed to mate with a portion of watch body 1120 and/or wearable band 1110 and wirelessly deliver usable power to battery 1298 of watch body 1120 and/or battery 1259 of wearable band 1110. Watch body 1120 and wearable band 1110 can have independent power systems (e.g., power system 1295 and 1256, respectively) to enable each to operate independently. Watch body 1120 and wearable band 1110 can also share power (e.g., one can charge the other) via respective PMICs (e.g., PMICs 1297 and 1258) and charger inputs (e.g., 1257 and 1296) that can share power over power and ground conductors and/or over wireless charging antennas.
In some embodiments, peripherals interface 1261 can include one or more sensors 1221. Sensors 1221 can include one or more coupling sensors 1262 for detecting when watch body 1120 is coupled with another electronic device (e.g., a wearable band 1110). Sensors 1221 can include one or more imaging sensors 1263 (e.g., one or more of cameras 1225, and/or separate imaging sensors 1263 (e.g., thermal-imaging sensors)). In some embodiments, sensors 1221 can include one or more SpO2 sensors 1264. In some embodiments, sensors 1221 can include one or more biopotential-signal sensors (e.g., EMG sensors 1265, which may be disposed on an interior, user-facing portion of watch body 1120 and/or wearable band 1110). In some embodiments, sensors 1221 may include one or more capacitive sensors 1266. In some embodiments, sensors 1221 may include one or more heart rate sensors 1267. In some embodiments, sensors 1221 may include one or more IMU sensors 1268. In some embodiments, one or more IMU sensors 1268 can be configured to detect movement of a user's hand or other location where watch body 1120 is placed or held.
In some embodiments, one or more of sensors 1221 may provide an example human-machine interface. For example, a set of neuromuscular sensors, such as EMG sensors 1265, may be arranged circumferentially around wearable band 1110 with an interior surface of EMG sensors 1265 being configured to contact a user's skin. Any suitable number of neuromuscular sensors may be used (e.g., between 2 and 20 sensors). The number and arrangement of neuromuscular sensors may depend on the particular application for which the wearable device is used. For example, wearable band 1110 can be used to generate control information for controlling an augmented reality system, a robot, controlling a vehicle, scrolling through text, controlling a virtual avatar, or any other suitable control task.
In some embodiments, neuromuscular sensors may be coupled together using flexible electronics incorporated into the wireless device, and the output of one or more of the sensing components can be optionally processed using hardware signal processing circuitry (e.g., to perform amplification, filtering, and/or rectification). In other embodiments, at least some signal processing of the output of the sensing components can be performed in software such as processors 1279. Thus, signal processing of signals sampled by the sensors can be performed in hardware, software, or by any suitable combination of hardware and software, as aspects of the technology described herein are not limited in this respect.
Neuromuscular signals may be processed in a variety of ways. For example, the output of EMG sensors 1265 may be provided to an analog front end, which may be configured to perform analog processing (e.g., amplification, noise reduction, filtering, etc.) on the recorded signals. The processed analog signals may then be provided to an analog-to-digital converter, which may convert the analog signals to digital signals that can be processed by one or more computer processors. Furthermore, although this example is as discussed in the context of interfaces with EMG sensors, the embodiments described herein can also be implemented in wearable interfaces with other types of sensors including, but not limited to, mechanomyography (MMG) sensors, sonomyography (SMG) sensors, and electrical impedance tomography (EIT) sensors.
In some embodiments, peripherals interface 1261 includes a near-field communication (NFC) component 1269, a global-position system (GPS) component 1270, a long-term evolution (LTE) component 1271, and/or a Wi-Fi and/or Bluetooth communication component 1272.

In some embodiments, the peripherals interface 1261 includes one or more indicators, such as a light emitting diode (LED), to provide a user with visual indicators (e.g., message received, low battery, active microphone and/or camera, etc.).
Watch body 1120 can include at least one display 1105 for displaying visual representations of information or data to a user, including user-interface elements and/or three-dimensional virtual objects. The display can also include a touch screen for inputting user inputs, such as touch gestures, swipe gestures, and the like. Watch body 1120 can include at least one speaker 1274 and at least one microphone 1275 for providing audio signals to the user and receiving audio input from the user. The user can provide user inputs through microphone 1275 and can also receive audio output from speaker 1274 as part of a haptic event provided by haptic controller 1278. Watch body 1120 can include at least one camera 1225, including a front camera 1225a and a rear camera 1225b.

Watch body computing system 1260 can include one or more haptic controllers 1278 and associated componentry (e.g., haptic devices 1276) for providing haptic events at watch body 1120 (e.g., a vibrating sensation or audio output in response to an event at the watch body 1120). Haptic controllers 1278 can communicate with one or more haptic devices 1276, such as electroacoustic devices, including a speaker of the one or more speakers 1274 and/or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating components (e.g., a component that converts electrical signals into tactile outputs on the device). Haptic controller 1278 can provide haptic events to that are capable of being sensed by a user of watch body 1120. In some embodiments, one or more haptic controllers 1278 can receive input signals from an application of applications 1282.

It should be appreciated that wearable band computing system 1230 is an example of a computing system within wearable band 1110, and that wearable band 1110 can have more or fewer components than shown in wearable band computing system 1230, combine two or more components, and/or have a different configuration and/or arrangement of the components. The various components shown in wearable band computing system 1230 can be implemented in one or more of a combination of hardware, software, or firmware, including one or more signal processing and/or application-specific integrated circuits.
Wrist-wearable device 1100 with respect to FIG. 11 is an example of wearable band 1110 and watch body 1120 coupled together, so wrist-wearable device 1100 will be understood to include the components shown and described for wearable band computing system 1230 and watch body computing system 1260. In some embodiments, wrist-wearable device 1100 has a split architecture (e.g., a split mechanical architecture, a split electrical architecture, etc.) between watch body 1120 and wearable band 1110. In other words, all of the components shown in wearable band computing system 1230 and watch body computing system 1260 can be housed or otherwise disposed in a combined wrist-wearable device 1100 or within individual components of watch body 1120, wearable band 1110, and/or portions thereof (e.g., a coupling mechanism 1116 of wearable band 1110).
The techniques described above can be used with any device for sensing neuromuscular signals but could also be used with other types of wearable devices for sensing neuromuscular signals (such as body-wearable or head-wearable devices that might have neuromuscular sensors closer to the brain or spinal column).
In some embodiments, wrist-wearable device 1100 can be used in conjunction with a head-wearable device (e.g., AR glasses 1300 and VR system 1410) and/or wrist-wearable device 1100 can also be configured to be used to allow a user to control any aspect of the artificial reality (e.g., by using EMG-based gestures to control user interface objects in the artificial reality and/or by allowing a user to interact with the touchscreen on the wrist-wearable device to also control aspects of the artificial reality). Having thus described example wrist-wearable devices, attention will now be turned to example head-wearable devices, such AR glasses 1300 and VR headset 1410.
FIGS. 13 to 15 show example artificial-reality systems, which can be used as or in connection with wrist-wearable device 1100. In some embodiments, AR system 1300 includes an eyewear device 1302, as shown in FIG. 13. In some embodiments, VR system 1410 includes a head-mounted display (HMD) 1412, as shown in FIGS. 14A and 14B. In some embodiments, AR system 1300 and VR system 1410 can include one or more analogous components (e.g., components for presenting interactive artificial-reality environments, such as processors, memory, and/or presentation devices, including one or more displays and/or one or more waveguides), some of which are described in more detail with respect to FIG. 15. As described herein, a head-wearable device can include components of eyewear device 1302 and/or head-mounted display 1412. Some embodiments of head-wearable devices do not include any displays, including any of the displays described with respect to AR system 1300 and/or VR system 1410. While the example artificial-reality systems are respectively described herein as AR system 1300 and VR system 1410, either or both of the example AR systems described herein can be configured to present fully-immersive virtual-reality scenes presented in substantially all of a user's field of view or subtler augmented-reality scenes that are presented within a portion, less than all, of the user's field of view.

The components shown in FIG. 13 can be implemented in hardware, software, firmware, or a combination thereof, including one or more signal-processing components and/or application-specific integrated circuits (ASICs).
Eyewear device 1302 includes mechanical glasses components, including a frame 1304 configured to hold one or more lenses (e.g., one or both lenses 1306-1 and 1306-2). One of ordinary skill in the art will appreciate that eyewear device 1302 can include additional mechanical components, such as hinges configured to allow portions of frame 1304 of eyewear device 1302 to be folded and unfolded, a bridge configured to span the gap between lenses 1306-1 and 1306-2 and rest on the user's nose, nose pads configured to rest on the bridge of the nose and provide support for eyewear device 1302, earpieces configured to rest on the user's ears and provide additional support for eyewear device 1302, temple arms configured to extend from the hinges to the earpieces of eyewear device 1302, and the like. One of ordinary skill in the art will further appreciate that some examples of AR system 1300 can include none of the mechanical components described herein. For example, smart contact lenses configured to present artificial reality to users may not include any components of eyewear device 1302.
Eyewear device 1302 includes electronic components, many of which will be described in more detail below with respect to FIG. 10. Some example electronic components are illustrated in FIG. 13, including acoustic sensors 1325-1, 1325-2, 1325-3, 1325-4, 1325-5, and 1325-6, which can be distributed along a substantial portion of the frame 1304 of eyewear device 1302.

FIGS. 14A and 14B show a VR system 1410 that includes a head-mounted display (HMD) 1412 (e.g., also referred to herein as an artificial-reality headset, a head-wearable device, a VR headset, etc.), in accordance with some embodiments. As noted, some artificial-reality systems (e.g., AR system 1300) may, instead of blending an artificial reality with actual reality, substantially replace one or more of a user's visual and/or other sensory perceptions of the real world with a virtual experience (e.g., AR systems 900 and 1000).
HMD 1412 includes a front body 1414 and a frame 1416 (e.g., a strap or band) shaped to fit around a user's head. In some embodiments, front body 1414 and/or frame 1416 include one or more electronic elements for facilitating presentation of and/or interactions with an AR and/or VR system (e.g., displays, IMUs, tracking emitter or detectors). In some embodiments, HMD 1412 includes output audio transducers (e.g., an audio transducer 1418), as shown in FIG. 14B. In some embodiments, one or more components, such as the output audio transducer(s) 1418 and frame 1416, can be configured to attach and detach (e.g., are detachably attachable) to HMD 1412 (e.g., a portion or all of frame 1416, and/or audio transducer 1418), as shown in FIG. 14B. In some embodiments, coupling a detachable component to HMD 1412 causes the detachable component to come into electronic communication with HMD 1412.
FIGS. 14A and 14B also show that VR system 1410 includes one or more cameras, such as left camera 1439A and right camera 1439B, which can be analogous to left and right cameras 1339A and 1339B on frame 1304 of eyewear device 1302. In some embodiments, VR system 1410 includes one or more additional cameras (e.g., cameras 1439C and 1439D), which can be configured to augment image data obtained by left and right cameras 1439A and 1439B by providing more information. For example, camera 1439C can be used to supply color information that is not discerned by cameras 1439A and 1439B. In some embodiments, one or more of cameras 1439A to 1439D can include an optional IR cut filter configured to remove IR light from being received at the respective camera sensors.
FIG. 15 illustrates a computing system 1520 and an optional housing 1590, each of which show components that can be included in AR system 1300 and/or VR system 1410. In some embodiments, more or fewer components can be included in optional housing 1590 depending on practical restraints of the respective AR system being described.
In some embodiments, computing system 1520 can include one or more peripherals interfaces 1522A and/or optional housing 1590 can include one or more peripherals interfaces 1522B. Each of computing system 1520 and optional housing 1590 can also include one or more power systems 1542A and 1542B, one or more controllers 1546 (including one or more haptic controllers 1547), one or more processors 1548A and 1548B (as defined above, including any of the examples provided), and memory 1550A and 1550B, which can all be in electronic communication with each other. For example, the one or more processors 1548A and 1548B can be configured to execute instructions stored in memory 1550A and 1550B, which can cause a controller of one or more of controllers 1546 to cause operations to be performed at one or more peripheral devices connected to peripherals interface 1522A and/or 1522B. In some embodiments, each operation described can be powered by electrical power provided by power system 1542A and/or 1542B.
In some embodiments, peripherals interface 1522A can include one or more devices configured to be part of computing system 1520, some of which have been defined above and/or described with respect to the wrist-wearable devices shown in FIGS. 11 and 12. For example, peripherals interface 1522A can include one or more sensors 1523A. Some example sensors 1523A include one or more coupling sensors 1524, one or more acoustic sensors 1525, one or more imaging sensors 1526, one or more EMG sensors 1527, one or more capacitive sensors 1528, one or more IMU sensors 1529, and/or any other types of sensors explained above or described with respect to any other embodiments discussed herein.
In some embodiments, peripherals interfaces 1522A and 1522B can include one or more additional peripheral devices, including one or more NFC devices 1530, one or more GPS devices 1531, one or more LTE devices 1532, one or more Wi-Fi and/or Bluetooth devices 1533, one or more buttons 1534 (e.g., including buttons that are slidable or otherwise adjustable), one or more displays 1535A and 1535B, one or more speakers 1536A and 1536B, one or more microphones 1537, one or more cameras 1538A and 1538B (e.g., including the left camera 1539A and/or a right camera 1539B), one or more haptic devices 1540, and/or any other types of peripheral devices defined above or described with respect to any other embodiments discussed herein.
AR systems can include a variety of types of visual feedback mechanisms (e.g., presentation devices). For example, display devices in AR system 1300 and/or VR system 1410 can include one or more liquid-crystal displays (LCDs), light emitting diode (LED) displays, organic LED (OLED) displays, and/or any other suitable types of display screens. Artificial-reality systems can include a single display screen (e.g., configured to be seen by both eyes), and/or can provide separate display screens for each eye, which can allow for additional flexibility for varifocal adjustments and/or for correcting a refractive error associated with a user's vision. Some embodiments of AR systems also include optical subsystems having one or more lenses (e.g., conventional concave or convex lenses, Fresnel lenses, or adjustable liquid lenses) through which a user can view a display screen.
For example, respective displays 1535A and 1535B can be coupled to each of the lenses 1306-1 and 1306-2 of AR system 1300. Displays 1535A and 1535B may be coupled to each of lenses 1306-1 and 1306-2, which can act together or independently to present an image or series of images to a user. In some embodiments, AR system 1300 includes a single display 1535A or 1535B (e.g., a near-eye display) or more than two displays 1535A and 1535B. In some embodiments, a first set of one or more displays 1535A and 1535B can be used to present an augmented-reality environment, and a second set of one or more display devices 1535A and 1535B can be used to present a virtual-reality environment. In some embodiments, one or more waveguides are used in conjunction with presenting artificial-reality content to the user of AR system 1300 (e.g., as a means of delivering light from one or more displays 1535A and 1535B to the user's eyes). In some embodiments, one or more waveguides are fully or partially integrated into the eyewear device 1302. Additionally, or alternatively to display screens, some artificial-reality systems include one or more projection systems. For example, display devices in AR system 1300 and/or VR system 1410 can include micro-LED projectors that project light (e.g., using a waveguide) into display devices, such as clear combiner lenses that allow ambient light to pass through. The display devices can refract the projected light toward a user's pupil and can enable a user to simultaneously view both artificial-reality content and the real world. Artificial-reality systems can also be configured with any other suitable type or form of image projection system. In some embodiments, one or more waveguides are provided additionally or alternatively to the one or more display(s) 1535A and 1535B.
Computing system 1520 and/or optional housing 1590 of AR system 1300 or VR system 1410 can include some or all of the components of a power system 1542A and 1542B. Power systems 1542A and 1542B can include one or more charger inputs 1543, one or more PMICs 1544, and/or one or more batteries 1545A and 1544B.
Memory 1550A and 1550B may include instructions and data, some or all of which may be stored as non-transitory computer-readable storage media within the memories 1550A and 1550B. For example, memory 1550A and 1550B can include one or more operating systems 1551, one or more applications 1552, one or more communication interface applications 1553A and 1553B, one or more graphics applications 1554A and 1554B, one or more AR processing applications 1555A and 1555B, and/or any other types of data defined above or described with respect to any other embodiments discussed herein.
Memory 1550A and 1550B also include data 1560A and 1560B, which can be used in conjunction with one or more of the applications discussed above. Data 1560A and 1560B can include profile data 1561, sensor data 1562A and 1562B, media content data 1563A, AR application data 1564A and 1564B, and/or any other types of data defined above or described with respect to any other embodiments discussed herein.
In some embodiments, controller 1546 of eyewear device 1302 may process information generated by sensors 1523A and/or 1523B on eyewear device 1302 and/or another electronic device within AR system 1300. For example, controller 1546 can process information from acoustic sensors 1325-1 and 1325-2. For each detected sound, controller 1546 can perform a direction of arrival (DOA) estimation to estimate a direction from which the detected sound arrived at eyewear device 1302 of R system 1300. As one or more of acoustic sensors 1525 (e.g., the acoustic sensors 1325-1, 1325-2) detects sounds, controller 1546 can populate an audio data set with the information (e.g., represented in FIG. 10 as sensor data 1562A and 1562B).
In some embodiments, a physical electronic connector can convey information between eyewear device 1302 and another electronic device and/or between one or more processors 1348, 1548A, 1548B of AR system 1300 or VR system 1410 and controller 1546. The information can be in the form of optical data, electrical data, wireless data, or any other transmittable data form. Moving the processing of information generated by eyewear device 1302 to an intermediary processing device can reduce weight and heat in the eyewear device, making it more comfortable and safer for a user. In some embodiments, an optional wearable accessory device (e.g., an electronic neckband) is coupled to eyewear device 1302 via one or more connectors. The connectors can be wired or wireless connectors and can include electrical and/or non-electrical (e.g., structural) components. In some embodiments, eyewear device 1302 and the wearable accessory device can operate independently without any wired or wireless connection between them.
In some situations, pairing external devices, such as an intermediary processing device (e.g., HIPD 706, 806, 906) with eyewear device 1302 (e.g., as part of AR system 1300) enables eyewear device 1302 to achieve a similar form factor of a pair of glasses while still providing sufficient battery and computation power for expanded capabilities. Some, or all, of the battery power, computational resources, and/or additional features of AR system 1300 can be provided by a paired device or shared between a paired device and eyewear device 1302, thus reducing the weight, heat profile, and form factor of eyewear device 1302 overall while allowing eyewear device 1302 to retain its desired functionality. For example, the wearable accessory device can allow components that would otherwise be included on eyewear device 1302 to be included in the wearable accessory device and/or intermediary processing device, thereby shifting a weight load from the user's head and neck to one or more other portions of the user's body. In some embodiments, the intermediary processing device has a larger surface area over which to diffuse and disperse heat to the ambient environment. Thus, the intermediary processing device can allow for greater battery and computation capacity than might otherwise have been possible on eyewear device 1302 standing alone. Because weight carried in the wearable accessory device can be less invasive to a user than weight carried in the eyewear device 1302, a user may tolerate wearing a lighter eyewear device and carrying or wearing the paired device for greater lengths of time than the user would tolerate wearing a heavier eyewear device standing alone, thereby enabling an artificial-reality environment to be incorporated more fully into a user's day-to-day activities.
AR systems can include various types of computer vision components and subsystems. For example, AR system 1300 and/or VR system 1410 can include one or more optical sensors such as two-dimensional (2D) or three-dimensional (3D) cameras, time-of-flight depth sensors, structured light transmitters and detectors, single-beam or sweeping laser rangefinders, 3D LiDAR sensors, and/or any other suitable type or form of optical sensor. An AR system can process data from one or more of these sensors to identify a location of a user and/or aspects of the use's real-world physical surroundings, including the locations of real-world objects within the real-world physical surroundings. In some embodiments, the methods described herein are used to map the real world, to provide a user with context about real-world surroundings, and/or to generate digital twins (e.g., interactable virtual objects), among a variety of other functions. For example, FIGS. 14A and 14B show VR system 1410 having cameras 1439A to 1439D, which can be used to provide depth information for creating a voxel field and a two-dimensional mesh to provide object information to the user to avoid collisions.
In some embodiments, AR system 1300 and/or VR system 1410 can include haptic (tactile) feedback systems, which may be incorporated into headwear, gloves, body suits, handheld controllers, environmental devices (e.g., chairs or floormats), and/or any other type of device or system, such as the wearable devices discussed herein. The haptic feedback systems may provide various types of cutaneous feedback, including vibration, force, traction, shear, texture, and/or temperature. The haptic feedback systems may also provide various types of kinesthetic feedback, such as motion and compliance. The haptic feedback may be implemented using motors, piezoelectric actuators, fluidic systems, and/or a variety of other types of feedback mechanisms. The haptic feedback systems may be implemented independently of other artificial-reality devices, within other artificial-reality devices, and/or in conjunction with other artificial-reality devices.
In some embodiments of an artificial reality system, such as AR system 1300 and/or VR system 1410, ambient light (e.g., a live feed of the surrounding environment that a user would normally see) can be passed through a display element of a respective head-wearable device presenting aspects of the AR system. In some embodiments, ambient light can be passed through a portion less that is less than all of an AR environment presented within a user's field of view (e.g., a portion of the AR environment co-located with a physical object in the user's real-world environment that is within a designated boundary (e.g., a guardian boundary) configured to be used by the user while they are interacting with the AR environment). For example, a visual user interface element (e.g., a notification user interface element) can be presented at the head-wearable device, and an amount of ambient light (e.g., 15-50% of the ambient light) can be passed through the user interface element such that the user can distinguish at least a portion of the physical environment over which the user interface element is being displayed.
The artificial-reality systems described herein may also include one or more input and/or output audio transducers. Output audio transducers may include voice coil speakers, ribbon speakers, electrostatic speakers, piezoelectric speakers, bone conduction transducers, cartilage conduction transducers, tragus-vibration transducers, and/or any other suitable type or form of audio transducer. Similarly, input audio transducers may include condenser microphones, dynamic microphones, ribbon microphones, and/or any other type or form of input transducer. In some embodiments, a single transducer may be used for both audio input and audio output.
In some embodiments, the artificial-reality systems described herein may also include tactile (i.e., haptic) feedback systems, which may be incorporated into headwear, gloves, body suits, handheld controllers, environmental devices (e.g., chairs, floormats, etc.), and/or any other type of device or system. Haptic feedback systems may provide various types of cutaneous feedback, including vibration, force, traction, texture, and/or temperature. Haptic feedback systems may also provide various types of kinesthetic feedback, such as motion and compliance. Haptic feedback may be implemented using motors, piezoelectric actuators, fluidic systems, and/or a variety of other types of feedback mechanisms. Haptic feedback systems may be implemented independent of other artificial-reality devices, within other artificial-reality devices, and/or in conjunction with other artificial-reality devices.
By providing haptic sensations, audible content, and/or visual content, artificial-reality systems may create an entire virtual experience or enhance a user's real-world experience in a variety of contexts and environments. For instance, artificial-reality systems may assist or extend a user's perception, memory, or cognition within a particular environment. Some systems may enhance a user's interactions with other people in the real world or may enable more immersive interactions with other people in a virtual world. Artificial-reality systems may also be used for educational purposes (e.g., for teaching or training in schools, hospitals, government organizations, military organizations, business enterprises, etc.), entertainment purposes (e.g., for playing video games, listening to music, watching video content, etc.), and/or for accessibility purposes (e.g., as hearing aids, visual aids, etc.). The embodiments disclosed herein may enable or enhance a user's artificial-reality experience in one or more of these contexts and environments and/or in other contexts and environments.
