Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation of International Application No. PCT/KR2022/014628, which was filed on Sep. 29, 2022, and claims priority to Korean Patent Application No. 10-2021-0138363, filed on Oct. 18, 2021, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein their entirety.

BACKGROUNDTechnical Field

Certain embodiments of the disclosure relate to wearable electronic devices, and, more particularly, to improving antenna performance for wearable electronic devices.

Description of Related Art

In recent times, wearable electronic devices have gained in prominence and market penetration. Such devices include augmented reality (AR) headsets, which sometimes can take the form of a pair of glasses (e.g., smart-glasses) and other head-mounted displays (HMD).

Wearable electronic device may transceive with another electronic device through, for example, wireless communication.

The wearable electronic device may include at least one antenna (e.g., a structure including a conductive pattern) so as to perform wireless communication with other, external electronic devices.

AR glasses are a type of wearable electronic device which take the form of glasses and/or smart-glasses, which can display various content to or via the glass surface (e.g., a lens).

Such AR-enabled glasses may implemented so as to include rims (e.g., the frames) and temples (e.g., the arms extending from the glasses rim), which may be connected thereto using hinges which permit folding and unfolding of the temples with respect to the rims.

To increase convenience and comfort, there are concerted efforts to reduce the weight of such wearable electronic devices. However, as the weight is reduced, the mounting space in the devices is often reduced for components, such as the antenna. As a result, the performance of any wireless communication may be degraded.

The wearable electronic device may be configured such that the antenna is disposed in one or both of the temples. When a user wears the wearable electronic device and a part of their body (e.g., the head, a face) contacts with the temples, a specific absorption rate (SAR) of radiation from the antenna to their body may be increased, and radiation performance of the antenna may be reduced.

According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connecting terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components (e.g., the connecting terminal 178) may be omitted from the electronic device 101, or one or more other components may be added in the electronic device 101. In some embodiments, some of the components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) may be implemented as a single component (e.g., the display module 160).

The processor 120 may execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120, and may perform various data processing or computation. According to an embodiment, as at least part of the data processing or computation, the processor 120 may store a command or data received from another component (e.g., the sensor module 176 or the communication module 190) in volatile memory 132, process the command or the data stored in the volatile memory 132, and store resulting data in non-volatile memory 134, which may in turn include the internal memory 136 and/or external memory 138.

For example, when the electronic device 101 includes the main processor 121 and the auxiliary processor 123, the auxiliary processor 123 may be adapted to consume less power than the main processor 121, or to be specific to a specified function. The auxiliary processor 123 may be implemented as separate from, or as part of the main processor 121.

A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology.

According to certain embodiments, the camera module 203 (e.g., the camera module 180 in FIG. 1) may be oriented to capture images from a front (e.g., a −y axis direction) of a user (e.g., a user of the wearable electronic device 200), and may obtain image data. The camera module 203 may photograph an image corresponding to a field of view (FoV) of a user and/or may implement depth-measurement for detecting a distance from a subject of photographic capture (e.g., an object). The camera module 203 may include an RGB camera, a high resolution (HR) camera and/or a photo video (PV) camera. In order to obtain high quality images, the camera module 203 may include a color camera having an auto focus (AF) function and an optical image stabilization (OIS) function.

According to certain embodiments, the first eye tracking camera 205 and the second eye tracking camera 207 may identify a user's line of sight. The first eye tracking camera 205 and the second eye tracking camera 207 may visually track the pupils of a user, and may thus be oriented in a direction opposite to a photographic direction of the camera module 203. For example, the first eye tracking camera 205 may partially capture the left eye of a user, and the second eye tracking camera 207 may partially capture the right eye of the user. The first eye tracking camera 205 and the second eye tracking camera 207 may detect the pupils (e.g., the left eye and the right eye) of a user within the captured image stream, and utilize the same to track the user's line of sight. The tracked direction of the line of sight may be used to detect center of a virtual image where the user's focus lies, including a virtual object, so that this center can move in accordance with changes in the direction of the line of sight. The first eye tracking camera 205 and/or the second eye tracking camera 207 may track a line of sight of a user by using at least one method among an electro-oculography or electrooculogram (EOG) sensor, a coil system, a dual Purkinje system, bright pupil systems, or dark pupil systems, for example.

According to certain embodiments, the audio module 209 (e.g., the audio module 170 in FIG. 1) may be disposed between the first eye tracking camera 205 and the second eye tracking camera 207. The audio module 209 may convert a voice of a user into an electrical signal or convert an electrical signal into a sound. The audio module 209 may include a microphone.

According to an embodiment, the first rim 210 and the second rim 220 may form frames (e.g., glasses frames) of the wearable electronic device 200 (e.g., AR glass). The first rim 210 may be disposed on a first side (e.g., in a first direction, such as an x axis direction) of the bridge 201. The first rim 210 may be disposed at a location corresponding to the left eye of the user. The second rim 220 may be disposed on a second side (e.g., in a second direction, such as an −x axis direction) of the bridge 201 (e.g., a direction opposite to the first direction, being the x axis direction). The second rim 220 may be disposed at a location corresponding to the right eye of the user. The first rim 210 and the second rim 220 may be formed by using a metal material and/or a non-metal material (e.g., polymer).

According to certain embodiments, the first rim 210 may surround and support at least a part of first glass 215 (e.g., a first display) disposed in the inner circumference surface of the first rim 210. The first glass 215 may be disposed in front of the left eye of a user. The second rim 220 may surround and support at least a part of second glass 225 (e.g., a second display) disposed in the inner circumference surface of the second rim 220. The second glass 225 may be disposed in front of the right eye of the user. A user of the wearable electronic device 200 may watch a foreground (e.g., an actual image) of an outside object (e.g., a subject for photographing) through the first glass 215 and the second glass 225. The wearable electronic device 200 may implement AR display by overlapping and displaying a virtual image in a foreground of a real-world object seen through transparency of the first glass 215 and second glass 225.

According to certain embodiments, the first glass 215 and the second glass 225 may include a projection type transparent display. Each of the first glass 215 and the second glass 225 may form a reflected surface as a transparent plate (or a transparent screen). An image generated by the wearable electronic device 200 may be reflected (e.g., total internal reflection) through the reflected surfaces, and may be incident on the left eye and right eye of a user. In an embodiment, the first glass 215 may include a waveguide for delivering, to the left eye of a user, light generated by a light source of the wearable electronic device 200. For example, the waveguide may be formed by using glass, plastic, or polymer material, and may include a nano pattern (e.g., a grating structure or mesh structure having a polygon or a curved shape) formed within or on a surface of the first glass 215. The waveguide may include at least one of at least one diffraction element (e.g., a diffractive optical element (DOE), a holographic optical element (HOE)) or a reflection element (e.g., a reflection mirror). The waveguide may guide, into an eye of a user, display light emitted from the light source by using at least one diffraction element or a reflection element included in the waveguide. In certain embodiments, the diffraction element may include an input/output optical member. The reflection element may include total internal reflection (TIR). For example, a light path of light emitted from the light source may be guided into the waveguide through the input optical member. Light that moves through the waveguide may be guided in an eye direction of a user through the output optical member. The second glass 225 may be implemented substantially in the same manner as the first glass 215.

According to certain embodiments, the first glass 215 and the second glass 225 may include a liquid crystal display (LCD), a digital mirror device (DMD), liquid crystal on silicon (LCoS), an organic light emitting diode (OLED), or a micro light emitting diode (micro LED), for example. Although not illustrated, if the first glass 215 and the second glass 225 include one of an LCD, a DMD, or LCoS, the wearable electronic device 200 may include a light source for radiating light to screen output areas of the first glass 215 and the second glass 225. In another embodiment, if the first glass 215 and the second glass 225 can autonomously generate light, for example, if the first glass 215 and the second glass 225 include one of an OLED or a micro LED, the wearable electronic device 200 can provide a user with a virtual image having excellent quality although a separate light source is not included.

The first recognition camera 213 and/or the second recognition camera 223 may detect a gesture of a user within a given distance (e.g., a given space) of the wearable electronic device 200. The first recognition camera 213 and/or the second recognition camera 223 may include a global shutter (GS) camera in which a rolling shutter (RS) phenomenon may be reduced, in order to detect and track a fast hand movement of a user and/or a fine movement for a finger. The wearable electronic device 200 may detect an eye corresponding to a fixing eye and/or a supplementary eye among the left eye and/or right eye of a user by using the first eye tracking camera 205, the second eye tracking camera 207, the first recognition camera 213 and/or the second recognition camera 223. For example, the wearable electronic device 200 may distinguish between a fixing eye and/or a supplementary eye of the user, based on a direction of a line of sight when viewing an outside object or a virtual object.

According to certain embodiments, the first light-emitting device 217 and/or the second light-emitting device 227 may emit light in order to increase the accuracy of the camera module 203, the first eye tracking camera 205, the second eye tracking camera 207, the first recognition camera 213 and/or the second recognition camera 223. The first light-emitting device 217 and/or the second light-emitting device 227 may be used as assistant for increasing accuracy when a pupil of a user is photographed by using the first eye tracking camera 205 and/or the second eye tracking camera 207. The first light-emitting device 217 and/or the second light-emitting device 227 may be used as assistant means when it is not easy to detect an object (e.g., a subject for photographing) to be photographed due to a dark environment or the mixing of several light sources and reflected light if a gesture of a user is photographed by using the first recognition camera 213 and/or the second recognition camera 223. The first light-emitting device 217 and/or the second light-emitting device 227 may include an LED, an IR LED, or a xenon lamp, for example.

According to certain embodiments, the first display module 219 and/or the second display module 229 may emit light, and may transmit the emitted light to the left eye and/or right eye of a user by using the first glass 215 and/or the second glass 225. The first glass 215 and/or the second glass 225 may display various types of image information using the light emitted through the first display module 219 and/or the second display module 229. The first display module 219 and/or the second display module 229 may include the display module 160 in FIG. 1.
