Various devices, arrangements and methods for managing communications using a head mounted display device are described. In one aspect, tracking data is generated at least in part by one or more sensors in a head mounted display (HMD) device. The tracking data indicates one or more facial movements of a user wearing the HMD device. A patch image is obtained based on the tracking data. The patch image is merged with a facial image. Various embodiments relate to the HMD device and other methods for generating and using the patch and facial images.

Methods, systems, apparatuses, and computer-readable media are provided for enabling collaboration between writers. In one implementation, the computer-readable medium includes instructions to cause a processor to receive, from an image sensor associated with a wearable extended reality appliance, image data representing a physical surface, the physical surface being a compilation of pages; receive, from a computing device associated with a virtual writer, annotation data representing first virtual markings associated with a first page of the compilation and second virtual markings associated with a second page of the compilation; analyze the image data to determine that the compilation is opened to the first page; and cause the wearable extended reality appliance to overlay the first virtual markings on the first page of the compilation and exclude overlaying the second virtual markings on the first page of the compilation.

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 targeting system for visualizing a target includes a targeting assembly having a main body mountable to a weapon and a rail-locking member selectively mountable to the main body. The main body supports at least one of a visual assembly, a power assembly, and a transmission assembly. Communicating with the targeting assembly is a viewing assembly.

Disclosed are methods and devices for providing an image of a scene and then displaying an image of the scene on a display screen with a changed field of view. Some embodiments of the disclosed methods and devices are useful for increasing a human's visual perception, especially when such a human has a visual field deficiency.

An image processing method and apparatus in a virtual reality device are provided, to resolve a low precision problem that is caused because existing VR glasses are adjusted by moving a lens to adapt to users with different myopic degrees. The method includes: determining, according to a visual acuity status of a user of a virtual reality device, a filtering parameter corresponding to visual acuity of the user; and for an image played on the virtual reality device, performing inverse filtering processing on the image according to the determined filtering parameter; and displaying, on a screen of the virtual reality device, an image obtained after the inverse filtering processing. Embodiments of the present invention also provide a device and a terminal for such image processing.

A head mounted display device comprises an optical combiner that combines light from a display and light from an environment into light transmitted towards a user's eye. A controllable optical element located in the light path from the environment, optically between the environment and the optical combiner, for passing light from the environment switchable between filtering and not filtering by optical blurring or diffusion. The device comprises a camera directed at the environment. A control circuit uses image data from the camera to compute a measure of contrast and/or a measure of luminance in a measurement region within an image or images captured by the camera and applies a control signal to the control input dependent on the measure of contrast and/or the measure of luminance. This is used to create or increase the filtering effect of controllable optical element with an increase of the measure of contrast and/or the measure of luminance.

The present disclosure provides a display apparatus, in which a shift of a transmission or reflection wavelength characteristic due to an incident angle of light is suppressed, and observation of external light necessary for display and image light necessary for display is possible. The display apparatus of the present disclosure includes an image light generator that generates image light by use of light in each of at least a first wavelength band, a second wavelength band, and a third wavelength band, and a light synthesizing part that transmits external light and reflects the image light. The light synthesizing part has a transparent substrate having a concave surface on which the image light is reflected, and a film that is provided on the concave surface of the substrate, reflects the image light, and transmits light in a predetermined wavelength band of the external light.

This invention provides an eyeglasses-type wearable information terminal including a position detector that detects a position, and a display controller that displays a map image for guidance to a destination to perform display suitable for a current situation during guidance to the destination. Here, as a characteristic feature, the display controller changes the transmittance of display of the map image in accordance with the distance between a current place and a point to change a traveling direction. This makes it possible to reliably change the traveling direction at the point to change the traveling direction.
