An imaging method is provided for a modular mixed reality (MR) device having an MR calculation module, an MR optical path module and an MR posture module. The MR calculation module is configured to adjust display content according to data from the MR posture module. The MR optical path module comprises a virtual-image optical path and a mixed optical path. A semi-transparent semi-reflective mirror is provided in the mixed optical path. One surface of the mirror is a real-image introduction surface facing a real environment, while the other is a virtual-image introduction surface facing the virtual-image optical path. Virtual-image light is reflected by the virtual-image introduction surface onto an observation end and mixed with real environment light transmitted to the observation end by the real-image introduction surface to form a mixed reality image.

A text entry method, a mobile device, a head-mounted display, and a storage medium are provided in implementations of the present disclosure. The mobile device has an operation interface, and the operation interface includes a keyboard area and a control area. The method includes the following. A first operation instruction is received at the keyboard area. At least one candidate text is displayed in the control area. A second operation instruction is received at the control area. A target text is determined from the at least one candidate text according to the second operation instruction, and the target text is transmitted to a text entry interface of a head-mounted display (HMD) for display.

Systems, methods, and non-transitory computer readable media configured for enabling content sharing between users of wearable extended reality appliances are provided. In one implementation, the computer readable medium may be configured to contain instructions to cause at least one processor to establish a link between a first wearable extended reality appliance and a second wearable extended reality appliance. The first wearable extended reality appliance may display first virtual content. The second wearable extended reality appliance may obtain a command to display first virtual content via the second wearable extended reality appliance, and in response, this content may be transmitted and displayed via the second extended reality appliance. Additionally, the first wearable extended reality appliance may receive second virtual content from the second wearable extended reality appliance, and display said second virtual content via the first wearable extended reality appliance.

Aspects of the present disclosure are directed to an artificial reality (XR) application system controlling applications in an artificial reality environment. In various cases, these controls include automatically suggesting XR applications by determining an XR context and identifying applications that match the XR context. These applications can be suggested to a user, who can authorize their execution, setting permissions for the application. In some cases, applications can be divided into components which can be progressively downloaded. By providing application suggestions relevant to the current context and progressively downloading application components, applications can appear ambient, rather than relying on users to constantly download, install, or activate applications. Permissions for applications may be revoked permanently or for certain situations—either through user permissions selections or automatically in response to determined user intents. When multiple applications are simultaneously authorized to execute, the XR application system can employ a ranking system to prevent overcrowding.

A ring-shaped earphone may be configured to be worn in an ear. When not worn in the ear, the ring-shaped earphone may be conveniently stored on a finger. In one example, the ring-shaped earphone may include a ring-shaped body defined by an outer cylindrical surface and an inner cylindrical surface. The earphone may include a speaker within the ring-shaped body. The speaker may be configured to project sound through a speaker opening in the outer cylindrical surface. The earphone may include a microphone within the housing. The microphone may be configured to receive sound through a microphone opening in the inner cylindrical surface.

According to a general aspect, a method can include receiving, by a computing device, an electronic communication. In response to receiving the electronic communication, the method can include determining, by the computing device, a current activity of a user of the computing device, and selecting, based on the determined current activity of the user, a communication channel of the computing device for providing a notification of the electronic communication. The method can also include providing the notification using the selected communication channel of the computing device.

Embodiments of the present disclosure disclose a presentation content update method, a head-mounted display device and a computer-readable medium. One specific embodiment of the method includes: determining three-axis attitude angles of a target device and three-axis attitude angles of a head-mounted display device based on first sensor data with respect to the target device sent by a first sensor and second sensor data with respect to the head-mounted display device sent by a second sensor; determining whether the three-axis attitude angles of the target device and the three-axis attitude angles of the head-mounted display device meet an attitude angle deviation detection condition; and updating presentation content on a display screen of the head-mounted display device in response to determining that the three-axis attitude angles of the target device and the three-axis attitude angles of the head-mounted display device meet the attitude angle deviation detection condition.

A wearable camera with mobile device optical coupling provides hands-free point-of-view video-chat. The mobile device optical coupling is enabled by an optic transfer engine that comprises a communications bus, a video decoding module, a micro-display, and a housing. The communications bus initially receives optical sensor data from an optical sensing device (e.g., the wearable camera). Next, the video decoding module decodes the optical sensor data. The micro-display displays the decoded optical sensor data. The housing partially encloses the communications bus, the video decoding module, and the micro-display and has a mounting element that is configured to removably mount the optics couple to a computing device such that the micro-display is positioned in a field of view of another optical sensing device coupled to the computing device.

An augmented reality (AR) device supporting an AR is provided. The AR device includes a display, a communication circuit, at least one processor operatively connected to the display and the communication circuit, and a memory operatively connected to the at least one processor. The memory stores instructions that, when executed, cause the at least one processor to establish a connection with a user device storing a contact application and a message application, through the communication circuit, detect that the message application is executed, and display a first graphic user interface (GUI) and at least one avatar, which is disposed at a location adjacent to the first GUI and corresponds to at least one contact associated with the contact application or the message application, through the display in the AR.

Systems and methods are provided for determining when to cease capturing video via a head-worn wearable device. The method includes capturing, via a head-worn wearable device that includes a camera, video data. The method further includes, while capturing the video data, monitoring sensor data indicating one or both of (i) a position of the head-worn wearable device and (ii) a position of a wrist-wearable device that is communicatively coupled with the head-worn device to determine when to cease capturing the video data. The method further includes, in accordance with a determination that at least some of the sensor data indicates that one or both of (i) a video-capturing precondition is not present at the head-worn wearable device and (ii) a video-viewing precondition is present at the wrist-wearable device, ceasing to capture the video data and causing the video data to be displayed on a display of the wrist-wearable device.
