A display image is superimposed and displayed on an outside image in a preferred manner. An optical system superimposes a display image displayed on a display device onto an outside image, and leads the display image to an eye of an observer. A display control unit controls the display size and the display position of the display image on the display device so that the display image is displayed in an image superimposition region (a flat region) detected from the outside image. For example, the display control unit controls the display state of the display image in accordance with the state of the image superimposition region in the outside image. Also, the display control unit performs control to selectively display the display image in a line-of-sight region or outside the line-of-sight region in accordance with the line of sight of the observer.

A head-mount display with exercise information displayed thereon includes an information box securely mounted on one temple of a frame, at least one wireless receiving unit mounted inside the information box, and a transparent body mounted on one front end of the information box in a visual range of a user. A display screen is mounted on an outer sidewall of the transparent body to display exercise information in the form of icon or text message, which is detected by the at least one wireless receiving unit. A magnifying lens is mounted on an inner sidewall of the transparent body to enlarge information displayed on the display screen as a virtual image for the user to view upon exercising. Accordingly, the head-mount display not only provides convenience in demonstrating information but also enhances space utilization efficiency of the display screen and recognition of exercise information on the display screen.

Systems, methods, and non-transitory computer readable media including instructions for extracting content from a virtual display are disclosed. Extracting content from a virtual display includes generating a virtual display via a wearable extended reality appliance, wherein the virtual display presents a group of virtual objects and is located at a first virtual distance from the wearable extended reality appliance; generating an extended reality environment via the wearable extended reality appliance including at least one additional virtual object at a second virtual distance from the wearable extended reality appliance; receiving input for causing a specific virtual object to move from the virtual display to the extended reality environment; and in response, generating a presentation of a version of the specific virtual object in the extended reality environment at a third virtual distance different from the first virtual distance and the second virtual distance.

A method of operating an electronic device to mitigate double vision is provided. The method can include using front-facing cameras to acquire passthrough content, using a graphics renderer to generate virtual content, mitigating double vision or improving vergence comfort by modifying at least the passthrough content, merging the passthrough content with the virtual content, and displaying the merged content. The passthrough content can be modified by selectively shifting or transforming left eye passthrough content or right eye passthrough content. The virtual content can be rendered based on a similar type of modification applied to the passthrough content. The virtual content can also be modified by selectively shifting or transforming left eye virtual content or right eye virtual content.

Systems, methods, and non-transitory computer readable media including instructions for performing duty cycle control operations for a wearable extended reality appliance are disclosed. Performing the duty cycle control operations includes receiving data representing virtual content in an extended reality environment associated with a wearable extended reality appliance; identifying in the extended reality environment a first display region and a second display region separated from the first display region; determining a first duty cycle configuration for the first display region; determining a second duty cycle configuration for the second display region, wherein the second duty cycle configuration differs from the first duty cycle configuration; and causing the wearable extended reality appliance to display the virtual content in accordance with the determined first duty cycle configuration for the first display region and the determined second duty cycle configuration for the second display region.

A head-mounted display device is provided, which relates to a field of display device technology. The device includes: a display unit used to display a picture; a connection unit used to position the display unit in front of at least one eye of a user after the head-mounted display device is worn on a head of the user; a rotating shaft unit includes at least a first segment, a second segment, and a first adjusting member connecting the first segment and the second segment, where the first segment is connected to the connection unit, and the first adjusting member is used to change a relative position of the first segment and the second segment when the first adjusting member is subjected to an external force, so that the second segment drives the display unit to move to achieve a pupil distance adjustment.

In some implementations, the device may include a first optical system corresponding to a first eye of the user and a second optical system corresponding to a second eye of the user, each of the first and second optical systems having: a projection unit configured to project light corresponding to an image; a lens operably including an optical element configured to direct the light from the projection unit to a respective eye motion box of the user. In addition, the device may include where the lens of the first optical system and the lens of the second optical system are symmetrically disposed about a mid-sagittal plane corresponding to a center of the nose bridge of the user, and where the first and second optical systems are geometrically asymmetric about the mid-sagittal plane.
