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.

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.

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.

Included are a first display element configured to display a first virtual image; a second display element configured to display a second virtual image; a combining optical member configured to combine first imaging light and second imaging light; a light-guiding optical system configured to guide light that passed through the combining optical member; and a correction optical system provided between the first display element and the combining optical member and configured to correct an aberration in accordance with a positional difference between the first display element and the second display element.

A directional backlit display device includes a light source module, a reflective narrow-angle diffuser, a backlit type display panel, an eye tracking device, and a controller. The diffuser includes a shaft and is utilized to reflect and uniformly diffuse the light to provide a uniform directional light beam. The backlit type display device panel is included on the projecting optical path of the uniform directional light beam. The uniform directional light beam illuminates an image displayed on the backlit type display device panel and projects to a projection area. The controller receives an eye position information from the eye tracking device and determines a coordinate. The controller determines a corrective projection area when the coordinate deviates from the projection area, and the drive module rotates the reflective narrow-angle diffuser around an axis of the shaft according to the corrective projection area, so the image projection area moves with the eye.

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.

In a display device, first to second data lines, first to second data transfer lines, first to fourth capacitance elements, a power supply line to which a fixed voltage is supplied, a first switch provided between the first data transfer line and the second capacitance element, a second switch provided between the power supply line and the second capacitance element, a third switch provided between the second data transfer line and the fourth capacitance element, a fourth switch provided between the power supply line and the fourth capacitance element, a first power supply supplying the fixed voltage to one end of the power supply line, and a second power supply supplying the fixed voltage to another end of the power supply line.

An optical device detachably attached to a frame fixed to a user's head is provided. The optical device includes a body extending in one direction, a display extending in a direction intersecting the one direction, connected to the body, and disposed to be adjacent to the user's eye when fixed to the frame, so as to provide visual information, and a clip module protruding from the body and caught in one region of the frame.

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.

Systems and methods are provided for verifying a magnetic positioning system. One embodiment includes a mounting unit, a drive unit, and a controller. The mounting unit is able to mechanically couple with a device that includes a magnetic sensor. The mounting unit includes a nonconductive mount to attach to the device, and a nonconductive swivel bearing with arms that are rotatably attached to the mount. The drive unit includes a platform, a nonconductive rigid post extending outward from the platform and attached to a center portion of the swivel bearing, linear actuators attached to the platform, and nonconductive shafts attached to the arms of the swivel bearing. Each shaft is attached to a linear actuator for displacement by the actuator. The controller directs the linear actuators to adjust the nonconductive shafts in order to move the swivel bearing, thereby adjusting an orientation and position of the device.
