FIG. 3A illustrates an input device 320. The input device 320 can be substantially similar to, and can include some or all of the feature of input devices 120 and 220 as described above, and input device 420 as described below. The input device 320 can be operably coupled with an electronic device, such as the electronic device 100, the wearable electronic device 200, and the HMD 250 discussed above. The input device 320 can include a cap or crown 328 defining an input surface 321. The input surface 321 can include a touch-sensitive interface. The crown 328 can be manipulated in a variety of directions. In some examples, this movement can include translation in one or more directions, rotation in both clockwise and counter-clockwise directions, tilt, and so on. The crown 328 can be moved by a user exerting a force on the crown 328, for example, with their finger. Moving the crown 328 can be used to generate a predetermined input signal corresponding to the motion.

The crown 328 can include an outer region 329, at least partially surrounding an inner region 326. In some examples, the outer region 329 in the inner region 326 of the crown 328 is a unitary component. In some examples, the outer region 329 and the inner region 326 are electrically coupled. In some examples, the outer region 329 and the inner region 326 are not electrically coupled. For instance, the outer region 329 can include a non-conductive material.

The crown 328 can include a central region 322 that is at least partially surrounded by the inner region 326. In some examples, the central region 322 can be electrically isolated from the inner region 326. For example, an insulator 330 can be positioned between the central region 322 and the inner region 326. As shown in FIG. 3B, in some examples, the inner region 326 is translatable relative to the central region 322. In some examples, the inner region 326 is rotatable relative to the central region 322. This decoupled structure between the central region 322, the inner region 326, and the outer region 329 can add increased functionality and capability to the input device 320. More particularly, the ability to independently select one or more of the central region 322, the inner region 326, and/or the outer region 329 via translation, rotation, or capacitive touch multiplies the number of input signals that can be provided by a single input device 320 in a relatively small footprint.

The input surface 321 of the input device can be defined by portions of the outer region 329, the inner region 326, and/or the central region 322. The input surface 321 can at least partially define an external surface of an electronic device on which the input device 320 is housed. In other words, the input surface 321 can be accessible to a user. As shown, a user's finger 324 can touch the input surface 321 (i.e., provide capacitive input). The input surface 321 can define a touch-sensitive interface at least partially defining multiple electrical paths capable of transmitting signals through the input device 320. For example, a touch by a user on one or more of the electrical paths can be used to generate a predetermined signal corresponding to the received touch input. Further, a sequence of touches along predetermined electrical paths can correspond to certain touch-gesture inputs.

The input device 320 can include a stem 331 extending from the crown 328. In some examples, the outer region 329, the inner region 326, and the central region 322 can be mechanically or physically coupled to the stem 331. Specifically, the stem 331 can include an inner cylinder 334 and an outer cylinder 332 that is electrically isolated from the inner cylinder 334 using an insulator 336. The outer cylinder 332 can include a notch or protrusion that engages with the inner region 326 such that a downward force exerted upon the inner region 326 and/or the outer region 329 transfers to the outer cylinder 332, causing downward motion of the inner region 326 and the outer cylinder 332. The outer cylinder 332 can include components 338 that are electromechanically coupled with brushes 340. Thus, the inner region 326 and/or the outer region 329 can be in electrical communication with the outer cylinder 332 and the components 338 such that a capacitive touch by the user's finger 324 on the inner region 326 or the outer region 329 is transferred to the outer cylinder 332, then to the components 338, and ultimately to the brushes 340, establishing a first electrical path.

In some examples, the central region 322 can be electrically and mechanically coupled with the inner cylinder 334 of the stem 331. The mechanical connection between the central region 322 and the inner cylinder 334 allows a force exerted on the central region 322 to be transferred to the inner cylinder 334. The inner cylinder 332 can include signal contacts or components 342 that are electromagnetically coupled to brushes 344. Thus, a capacitive touch by a finger 324 on the central region 322 can be transferred to the inner cylinder 334, then to the components 342, and ultimately to the brushes 344, establishing a second electrical path. It will be understood that extrapolating the described configuration, more than two electrical paths are possible. The multiple electrical paths of the input device 320 can be used to mitigate false signals produced by water or moisture on the input surface. The distinct electrical paths can identify different capacitances between moisture, a finger, and a ground capacitance, and can accordingly disregard input determined to be produced by a moisture event.

In some examples, the bottom portion of the stem 331 is the point of contact between the input device 320 and the electronic device which carries the input device 320. The bottom of the stem 331 can be the only point of physical contact with the electronic device (i.e., the crown 328 does not, in some examples, contact the housing or any other portion of the electronic device).

The stem 331 can be made with a compliant or flexible material. In some examples, the stem 331 includes a spring. The stem 331 can include strain gauges to determine the movement of the stem 331. In some examples, the brushes 340, 344 can have springs to deflect or depress in response to a change in the angle of the stem 331 relative to the brushes 340, 344, as detailed below with reference to FIGS. 7A and 7B.

In some examples, the input device 320 can include touch pixels, electrocardiogram (ECG) sensors, and other electrical inputs. In some examples, the input device 320 includes at least one of an optical encoder and a magnetic encoder. Signals can be detected using optical, conductive, magnetic, or mechanical encoders, individually or in any combination.

FIG. 3B illustrates an example configuration of the input device 320 in which the outer region 329 and the inner region 326 have been pushed down relative to the central region 322. By exerting a downward force on the inner region 326, the outer cylinder 332 can travel downward due to the mechanical link between the inner region 326 and the outer cylinder 332. In some examples, the outer cylinder 332 is restricted from travelling a distance that would cause interference between the components 338 of the first electrical path and the components 342 of the second electrical path.

In some examples, the input device 320 can be translationally fixed. An attempted or intended translation of the input device 320 (e.g., push or press) can be determined using one or more sensors positioned on the input surface 321. For example, the capacitive sensors and/or force pressure sensors can be used to detect an intended translation of the input device 320. Further details of example features of the input device are provided below with reference to FIGS. 4A and 4B.

FIG. 4A illustrates a schematic top view of a crown 428. FIG. 4B illustrates a schematic bottom view of the crown 428. The crown 428 can be substantially similar to the crown 328 described above. In some examples, the input device 420 defines an input surface 421. The input surface 421 can include a plurality of conductive pads or electrodes that at least partially define a series of distinct electrical paths, as shown in FIG. 4B. For example, the crown 428 can include a first set of electrodes 430 forming a first electrical path 429, a second set of electrodes 427 forming a second electrical path 426, and a third set of electrodes 423 forming a third electrical path 422. The electrical paths 422, 426, and 429 can be electrically isolated from one another such that a processor electrically coupled to each of the electrical paths can detect whether the signal is coming from the first set of electrodes 430, the second set of electrodes 427, the third set of electrodes 423, or combinations thereof.

In some examples, a swipe can be detected by registering a series of capacitive touches that occur in rapid succession among the first set of electrodes 430, the second set of electrodes 427, or the third set of electrodes 423. In a specific example, a swipe can be determined by detecting, in order, signals at the first electrical path 429, the second electrical path 426, the third electrical path 422, the second electrical path 426, and the first electrical path 429. Further, depending on which electrodes are activated, the direction, speed, and/or magnitude of the swipe can be determined (e.g., swipe up, down, left, right, diagonally, etc.). Further, non-linear gestures or swipes can be detected by the crown 428. For example, a circular gesture can be detected in response to detecting a succession of touches on the electrodes positioned in a circular configuration (e.g., a counter-clockwise circular gesture can be determined by detecting touches along the left, bottom, right, and top electrodes 430 within a predetermined amount of time). Alternatively, an array of electrodes can be positioned on the exterior of the crown, which when touched, can signal a desired rotation of the crown. A swiping motion as described above is illustrated in FIG. 5A.

In some examples, the crown 428 is rotationally fixed. An attempted or intended rotation of the crown 428 can be determined using one or more sensors positioned on the crown. For example, the outer perimeter or sidewall of the crown 428 can include conductive pads or electrodes that can be used detect an intended rotation of the crown 428. A determination that the user is attempting to rotate the crown 428 can be made upon detecting a first touch at a first location on the perimeter of the crown 428 and subsequently detecting a second touch at a second location on the crown 428. In some examples, the first touch and the second touch occurring within a predetermined amount of time results in a determination of intended rotation. In some examples, the first touch and the second touch occurring without the user removing their finger results in a determination of intended rotation.

FIG. 5A shows a top view of an operation of an input device 520. The input device 520 can be substantially similar to, including some or all of the features of, the input devices 120, 220, 320, and 420, as described herein. The operation shown in FIG. 5A represents a specific use case of a user's finger 524 swiping across the input member 520. As the user's finger 524 passes across the input member 520, one or more electrical paths 529, 522 can detect the presence and direction of the user's finger 524 on the input device 520. The electrical paths 529 and 522 can determine that the user's finger 524 is swiping in a generally straight line from left to right, as oriented in FIG. 5A. It will be understood that the input device 520, in connection with a processor, can detect swipes in any direction, and can further detect non-linear patterns of the finger 524 on the input device 520 (e.g., circular swipes potentially indicating an intended rotation of the input device 520). Furthermore, the input device 520 can detect the velocity of the swipes to add further fidelity to the response signal generated by the input device. An exemplary response to an input detected by the input device 520 is provided below with reference to FIG.

FIG. 5B shows a user interface 503 responsive to the operation of FIG. 5A. The user interface 503 can, in one example, be a display of an HMD. In some examples, swiping the finger 524 across the input device 520 can generate a signal that is interpreted by a processor to cause a display to scroll through, or to move among or between, displayed pages or applications 505. The direction of the displayed applications 505 can correspond to the direction of the swipe on the input device 520. For example, in FIG. 5A, the user's finger 524 swipes from left to right. Thus, the movement of the applications 505 displayed on the user interface 503 can likewise move from left to right, as viewed by the user. In other words, the movement of the applications 505 can mirror the detected movement of the user's finger 524 on the input device 520. The speed in which the applications 505 move can correspond to a detected velocity of the user's finger 524 across the surface of the input device 520. Manipulation of the applications 505 can occur in any number of directions, sequences, or orientations. Additional system functions can also be controlled via the described input device 520, as detailed below with reference to FIG. 5C

FIG. 5C shows a command indicator 507 displayed on the user interface 503. The command indicator 507 can be responsive to the swipe of FIG. 5A. Input provided at the input device 520 can adjust a variety of settings on an HMD, such as volume, video speed/position, brightness, track selection, etc. FIG. 5C illustrates a specific use case in which the swipe from left to right, as shown in FIG. 5A, corresponds to a command to fast forward or skip forward in a media application being viewed or listened to by the user. In some examples, the user can program personalized movements on the input device 520 to correspond to certain commands. In this manner, when a user desires to skip or fast forward a media application being viewed by the user, the user can controllably swipe the input device to selectively skip or fast forward the media application, with corresponding functional indicators 507 being presented to the user on the user interface 503, or otherwise impact the computer-generated reality. In addition to direct touch detection, the input device can have added functionality, as detailed below with reference to FIGS. 6A-6D.

FIG. 6A shows a perspective view of an operation of an input device 620. The input device 620 can be substantially similar to, including some or all of the features of, the input devices 120, 220, 320, 420, and 520 as described herein. The input device 620 can be positioned on an HMD housing 254 or any other electronic device. In some examples, a proximity of a finger 624 to the surface of the input member 620 can be determined and can initiate functionalities of the HMD. This capability can be referred to as hover or proximity detection. According to one example, when a finger 624 or other body part is moved to with a distance “d” of the input member 620, the presence of the finger is detected and can initiate a functionality of the HMD. Referring to FIG. 6B, the proximity of the finger 624 can be determined by a change in the electric field at the input member 620 due to the proximity of the finger 624, and/or by one or more sensors 658 present on the housing 654 of the HMD. In some examples the sensor 658 is an external cameras capable of monitoring the position of the user's finger 624 in relation to the input device 620.

FIG. 6C shows a user interface 603 responsive to the operation of FIGS. 6A and 6B. The user interface 603 can be a display of an HMD. In response to detecting a proximity of the user's finger to the input device (i.e., hover or proximity detection), a graphical icon 609 can appear on the user interface 603. The graphical icon 609 can represent a positional relationship between the user's finger and the input device 620. In some examples, an actual image captured by the external camera 658 can be displayed on the user interface 603 showing the user's hand approaching the input device 620. The graphical icon 609 notify a user that their finger is near the input device and can assist the user in locating the input device 620 before the finger actually engages the input device. In some examples, audio indicators can also correspond to a proximity of the user's finger (e.g., a sound increases in volume as the user's finger draws closer to the input device 620). In some examples, hover or proximity detection of the user's finger can prompt an action on the user interface 603. For example, upon determining that the user's finger is hovering at or near the input device 620, active media can be paused.

FIG. 6D shows an example process flow diagram 600 of the hover detection feature. At step 650, an electronic device, such as an HMD, maintains a low power or standby mode. The HMD can assume the low power or standby mode in order to save battery life and can occur as a natural result of non-use or can result from the user inputting a command to enter the low power or standby mode. In some instances, removal of the HMD can place the device in a low power or standby mode. At step 660, the HMD can detect a near touch/hover or input at the input device using the procedures described above. This near touch/hover detection can occur when a user grasps the HMD to move it or to again place the HMD on their head for further use. At step 670, the HMD can, in response to the detected near touch/hover or input at step 660, can initiate a startup or enters an awake mode. The process 600 can conserve power and can also predict an upcoming use of the HMD and can initiate procedures to prepare for the predicted use. This allows the HMD to start up and be at or near operation mode when placed on the user's head, thereby enhancing the user experience. Further functionalities of the input member are provided below with reference to FIGS. 7A and 7B. FIG. 7A shows a side view of an operation of an input member 720. The input device 720 can be substantially similar to, including some or all of the features of, the input devices 120, 220, 320, 420, 520, and 620 as described herein. The input member 720 can be configured to operate as a joystick. That is, the crown 728 and stem 731 of the input device 720 can pivot or tilt in multiple directions and at various angles in response to a force applied by a user's finger 724. Sensors 740, such as a pivot detection sensor, can detect and report the angle and direction of the input device 720 via signals that are interpreted by a processor and graphically represented on a user interface.

FIG. 7B shows a user interface 703 responsive to the detected tilt movement of the input device 720, as shown in FIG. 7A. The user interface 703 can be a display of an HMD, according to one example. In a specific use case, a graphical icon, such as a cursor 711, can be controlled by the detected motion of the input device 720. For example, FIG. 7A depicts the input device being tilted to the right, which, as shown in FIG. 7B, can cause the cursor 711 to move to the right on the user interface 703. Additionally, the angle at which the input device is tilted can provide additional input and control of the user interface 703. For example, larger angle or greater tilt of the input device 720 can cause an increase in the speed of the cursor 711 as it moves across the screen. Additional exemplary combinations and functionalities of the input device are provided below with reference to FIGS. 8A and 8B.

FIG. 8A shows a side view of an operation of an HMD 850. Again, as used herein, the term HMD can include smart glasses. The HMD 850 can include a frame 860 and a user interface 854. An input device 820 and camera 858 can be positioned on the HMD 850. The camera 858 can be used to track a gaze of the user. The input device 820 can be substantially similar to, including some or all of the features of, the input devices 120, 220, 320, 420, 520, 620, and 720 as described herein. In some examples, the input device 820 can be used in combination with the gaze tracking camera 858 to provide input, command, and control to the HMD 850.

FIG. 8B shows a specific use case of a user interface 803 of the HMD 850 of FIG. 8A. As shown in FIG. 8B, the user interface 803 can include multiple graphical icons or applications 805. The user interface 803 can be controlled by the input device 820 and the gaze tracking camera 858, individually or in combination. For example, input by a user's finger 824 at the input device 820 can cause the applications 805 to move or change. The input at the input device 820 can be a swipe, a rotation, a tilt, or combinations thereof, as discusses above. A second input can then be provided by determining the gaze of the user. For example, the gaze tracking camera 858 can determine that the user is looking at, and or visually tracking, a specific icon 813 and can perform a function based on that determination. For instance, the application corresponding to icon 813 can be selected and/or opened if the gaze tracking camera 858 determines that a user is focused on a specific icon 813 for a pre-determined period of time while the input device 820 is engaged. In this manner, the user interface 803 can be interacted with using a combination of the input device 820 and gaze tracking camera 858. It will be understood that additional controllers can likewise work in concert with the input device 820 to provide input to the HMD 850.

Using the systems, methods, and processes discussed above, a vision system of a wearable device can have enhanced user interaction and can improve the user experience.

Physical environment: A physical environment refers to a physical world that people can sense and/or interact with without aid of electronic systems. Physical environments, such as a physical park, include physical articles, such as physical trees, physical buildings, and physical people. People can directly sense and/or interact with the physical environment, such as through sight, touch, hearing, taste, and smell.

Computer-generated reality: in contrast, a computer-generated reality (CGR) environment refers to a wholly or partially simulated environment that people sense and/or interact with via an electronic system. In CGR, a subset of a person's physical motions, or representations thereof, are tracked, and, in response, one or more characteristics of one or more virtual objects simulated in the CGR environment are adjusted in a manner that comports with at least one law of physics. For example, a CGR system may detect a person's head turning and, in response, adjust graphical content and an acoustic field presented to the person in a manner similar to how such views and sounds would change in a physical environment. In some situations (e.g., for accessibility reasons), adjustments to characteristic(s) of virtual object(s) in a CGR environment may be made in response to representations of physical motions (e.g., vocal commands). A person may sense and/or interact with a CGR object using any one of their senses, including sight, sound, touch, taste, and smell. For example, a person may sense and/or interact with audio objects that create 3D or spatial audio environment that provides the perception of point audio sources in 3D space. In another example, audio objects may enable audio transparency, which selectively incorporates ambient sounds from the physical environment with or without computer-generated audio. In some CGR environments, a person may sense and/or interact only with audio objects. Examples of CGR include virtual reality and mixed reality.

Virtual reality: A virtual reality (VR) environment refers to a simulated environment that is designed to be based entirely on computer-generated sensory inputs for one or more senses. A VR environment includes a plurality of virtual objects with which a person may sense and/or interact. For example, computer-generated imagery of trees, buildings, and avatars representing people are examples of virtual objects. A person may sense and/or interact with virtual objects in the VR environment through a simulation of the person's presence within the computer-generated environment, and/or through a simulation of a subset of the person's physical movements within the computer-generated environment.

Mixed reality: In contrast to a VR environment, which is designed to be based entirely on computer-generated sensory inputs, a mixed reality (MR) environment refers to a simulated environment that is designed to incorporate sensory inputs from the physical environment, or a representation thereof, in addition to including computer-generated sensory inputs (e.g., virtual objects). On a virtuality continuum, a mixed reality environment is anywhere between, but not including, a wholly physical environment at one end and virtual reality environment at the other end. In some MR environments, computer-generated sensory inputs may respond to changes in sensory inputs from the physical environment. Also, some electronic systems for presenting an MR environment may track location and/or orientation with respect to the physical environment to enable virtual objects to interact with real objects (that is, physical articles from the physical environment or representations thereof). For example, a system may account for movements so that a virtual tree appears stationery with respect to the physical ground. Examples of mixed realities include augmented reality and augmented virtuality. Augmented reality: an augmented reality (AR) environment refers to a simulated environment in which one or more virtual objects are superimposed over a physical environment, or a representation thereof. For example, an electronic system for presenting an AR environment may have a transparent or translucent display through which a person may directly view the physical environment. The system may be configured to present virtual objects on the transparent or translucent display, so that a person, using the system, perceives the virtual objects superimposed over the physical environment. Alternatively, a system may have an opaque display and one or more imaging sensors that capture images or video of the physical environment, which are representations of the physical environment. The system composites the images or video with virtual objects, and presents the composition on the opaque display. A person, using the system, indirectly views the physical environment by way of the images or video of the physical environment, and perceives the virtual objects superimposed over the physical environment. As used herein, a video of the physical environment shown on an opaque display is called “pass-through video,” meaning a system uses one or more image sensor(s) to capture images of the physical environment, and uses those images in presenting the AR environment on the opaque display. Further alternatively, a system may have a projection system that projects virtual objects into the physical environment, for example, as a hologram or on a physical surface, so that a person, using the system, perceives the virtual objects superimposed over the physical environment. An augmented reality environment also refers to a simulated environment in which a representation of a physical environment is transformed by computer-generated sensory information. For example, in providing pass-through video, a system may transform one or more sensor images to impose a select perspective (e.g., viewpoint) different than the perspective captured by the imaging sensors. As another example, a representation of a physical environment may be transformed by graphically modifying (e.g., enlarging) portions thereof, such that the modified portion may be representative but not photorealistic versions of the originally captured images. As a further example, a representation of a physical environment may be transformed by graphically eliminating or obfuscating portions thereof. Augmented virtuality: an augmented virtuality (AV) environment refers to a simulated environment in which a virtual or computer generated environment incorporates one or more sensory inputs from the physical environment. The sensory inputs may be representations of one or more characteristics of the physical environment. For example, an AV park may have virtual trees and virtual buildings, but people with faces photorealistically reproduced from images taken of physical people. As another example, a virtual object may adopt a shape or color of a physical article imaged by one or more imaging sensors. As a further example, a virtual object may adopt shadows consistent with the position of the sun in the physical environment.

Hardware: there are many different types of electronic systems that enable a person to sense and/or interact with various CGR environments. Examples include head mounted systems, projection-based systems, heads-up displays (HUDs), vehicle windshields having integrated display capability, windows having integrated display capability, displays formed as lenses designed to be placed on a person's eyes (e.g., similar to contact lenses), headphones/earphones, speaker arrays, input systems (e.g., wearable or handheld controllers with or without haptic feedback), smartphones, tablets, and desktop/laptop computers. A head mounted system may have one or more speaker(s) and an integrated opaque display. Alternatively, a head mounted system may be configured to accept an external opaque display (e.g., a smartphone). The head mounted system may incorporate one or more imaging sensors to capture images or video of the physical environment, and/or one or more microphones to capture audio of the physical environment. Rather than an opaque display, a head mounted system may have a transparent or translucent display. The transparent or translucent display may have a medium through which light representative of images is directed to a person's eyes. The display may utilize digital light projection, OLEDs, LEDs, μLEDs, liquid crystal on silicon, laser scanning light sources, or any combination of these technologies. The medium may be an optical waveguide, a hologram medium, an optical combiner, an optical reflector, or any combination thereof. In one embodiment, the transparent or translucent display may be configured to become opaque selectively. Projection-based systems may employ retinal projection technology that projects graphical images onto a person's retina. Projection systems also may be configured to project virtual objects into the physical environment, for example, as a hologram or on a physical surface.

To the extent applicable to the present technology, gathering and use of data available from various sources can be used to improve the delivery to users of invitational content or any other content that may be of interest to them. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, TWITTER® ID's, home addresses, data or records relating to a user's health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information.

The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to deliver targeted content that is of greater interest to the user. Accordingly, use of such personal information data enables users to calculated control of the delivered content. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data may be used to provide insights into a user's general wellness, or may be used as positive feedback to individuals using technology to pursue wellness goals.

The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country.

Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of advertisement delivery services, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In another example, users can select not to provide mood-associated data for targeted content delivery services. In yet another example, users can select to limit the length of time mood-associated data is maintained or entirely prohibit the development of a baseline mood profile. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app.

Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user's privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods.

Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the content delivery services, or publicly available information.

The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the described embodiments. However, it will be apparent to one skilled in the art that the specific details are not required in order to practice the described embodiments. Thus, the foregoing descriptions of the specific embodiments described herein are presented for purposes of illustration and description. They are not target to be exhaustive or to limit the embodiments to the precise forms disclosed. It will be apparent to one of ordinary skill in the art that many modifications and variations are possible in view of the above teachings.
