A transmissive image display device includes an image generation part configured to emit a light, and a light-guiding optical system configured to guide the light. The light-guiding optical system includes a first deflection part configured to deflect the light, and a second deflection part configured to further deflect the light deflected by the first deflection part to guide the light to a position of the exit pupil while transmitting a portion of external light, a first external light transmittance adjustment part is provided outside an optical path of the light between the first deflection part and the second deflection part, and an average external light transmittance of the first external light transmittance adjustment part is higher than one of an average external light transmittance of the first deflection part and an average external light transmittance of the second deflection part lower than the other.

A head-mounted device may have head-mounted support structures configured to be worn on a head of a user. The head-mounted device may have stereo optical components such as left and right cameras or left and right display systems. The optical components may have respective left and right pointing vectors. Deformation of the support structures may cause the camera pointing vectors and/or the display system pointing vectors to become misaligned. Sensor circuitry such as strain gauge circuitry may measure pointing vector misalignment. Control circuitry may control the cameras and/or the display systems to compensate for measured changes in pointing vector misalignment.

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.

An image processing method and apparatus in a virtual reality device are provided. 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. For an image played on the virtual reality device, an inverse filtering processing is performed on the image according to the determined filtering parameter. An image obtained after the inverse filtering processing is then displayed on a screen of the virtual reality device. Embodiments of the present invention also provide a device and a terminal for such image processing.

Various aspects of the subject technology relate to display panels for head-mountable devices. A display panel may include a left-eye pixel array and a right-eye pixel array that are each rotated with respect to a horizontal defined by a straight line connecting the centers of the arrays. The rotated pixel arrays each include data lines and scan lines that extend at oblique angles relative to the horizontal. A liquid crystal layer of the display panel may include liquid crystal molecules having a default orientation at an oblique angle relative to both the data lines and the scan lines of both of the rotated pixel arrays. The rotated pixel arrays may each include pixel circuits arranged along the data lines and scan lines, each pixel circuit including a transparent electrode oriented at an oblique angle relative to both the scan lines and the data lines.

Methods, systems, apparatuses, and computer-readable media are provided for enabling collaboration between physical writers and virtual writers. In one implementation, the computer-readable medium includes instructions to cause a processor to receive, from an image sensor, image data representing a hand of a first physical writer holding a physical marking implement and engaging with a physical surface to create tangible markings. Information based on the image data is transmitted to a computing device associated with a second virtual writer, to thereby enable the second virtual writer to view the tangible markings created by the first physical writer. Annotation data are received from the computing device, and represent additional markings in relative locations with respect to the tangible markings created by the first physical writer. In response to receiving the annotation data, a wearable extended reality appliance overlays the physical surface with virtual markings in the relative locations.

Headsets and head-mounted displays including first and second diffractive elements are described. In some cases, the first and second diffractive elements include first and second grating surfaces, and for at least one wavelength, the first and second grating surfaces have at least one different corresponding diffractive property. The head-mounted display may include two-dimensionally pixelated adjacent first and second display surfaces for displaying images, and first and second diffractive elements disposed adjacent the respective first and second display surfaces. In some cases, the first diffractive element is configured to diffract a first wavelength 1, but not a different second wavelength into zero and first diffraction orders having intensities within 5% of each other, and the second diffractive element is configured to diffract the second wavelength but not the first wavelength 1, into zero and first diffraction orders having intensities within 5% of each other.
