A wearable optical system allows a user to watch a large screen, such as a smartphone screen, in a wide field of view (FOV) with both eyes, the field superimposed on the real world. The screen displays two separate zones to be the data source for each eye. The system includes two projection optical subassemblies based on a pupil forming eye piece. The interpupilarity distance (IPD) is adjusted by rotating each optical subassembly about a pivot, which is perpendicular to its specific display zone.

This invention teaches a binocular telescope wherein wedge prisms are positioned in the optical path of each telescope to control the amount of perceived parallax between the left and the right images. In one embodiment, a pair of thin wedge prisms are positioned in front of the objective lenses to optically manipulate the real convergence angle of an object viewed through the binocular telescope. In a second embodiment, wedge prisms are positioned after the eyepiece lenses to manipulate the apparent convergence angle of an object viewed through the binocular telescope. Depending on the position and the orientation of the wedge prisms, the invention produces benefits such as better depth perception, increased field of view, and the possibility to view close objects.

There is provided a display device including a display unit that displays an image thereon, an eyepiece optical unit that projects a display image of the display unit on the eyes of a user, a correction information retaining unit that retains correction information created in advance according to a state of the user, and a distortion correction unit that corrects distortion of the display image based on correction information according to a current state of the user.

A head-mounted display device is disclosed that includes an at least partially see-though display, a processor, and a non-volatile storage device holding instructions executable by the processor to: select an image that corresponds to a physical object viewable by the user; display the image at a perceived offset to the physical object; in response to alignment user input, move a perceived position of the image relative to the physical object; output an instruction to provide completion user input when the image appears to align with the physical object; when the completion user input is received, determine the inter-pupillary distance of the user; and calibrate the head mounted display device based on the inter-pupillary distance.

Stereoscopic viewing systems may be adjusted for a user's inter-pupillary distance (IPD). An inter-pupillary distance (IPD) value is determined from a signal from a position sensitive device coupled to two moveable sighting fixtures mounted to a head mounted display (HMD) having two fixed optics configured for a specific inter-pupillary distance. The position sensitive device is configured to produce a signal that corresponds to a distance between the two sighting fixtures. The images are warped with a processor to optimize display of the images with the two fixed optics for the determined IPD value.

The invention relates to a binocular telescope comprising two tubes, which are connected in an articulate fashion with a swivel hinge pivotal around a joint bending axis. With a forehead contact unit comprising a comprehensive support device the binoculars can be supported in the area of the root of the nose or the forehead of the observer. The support device is here arranged at a body of the binoculars.

An electronic display includes a display panel that operates in a single display mode to provide a single display, or a dual display mode to provide two displays separated by an inactive region. The electronic display includes the display panel and a panel driver. The display panel includes a left pixel region, a right pixel region, and a middle pixel region between the left and right pixel regions. In the single display mode of the electronic display, the panel driver provides first gate signals generated from first input data to the left, right, and middle pixel regions. In a dual display mode, the panel driver provides second gate signals generated from second input data to the left and right pixel regions. The first input data has a first resolution that is larger than a second resolution of the second input data.
