Stereoscopic display systems and methods for displaying surgical data and information in a surgical microscope are disclosed herein. According to an aspect, a system includes first and second eyepieces. The system includes a display having first and second display portions, configured to display first images in the first display portion, and configured to display second images in the second display portion. The first image and the second image are projected along a first pathway and a second pathway. The system includes a first optical element positioned to relay the first images into the first eyepiece. The system includes a second optical element positioned to relay the second images into the second eyepiece.

A virtual object display system includes a plurality of head-mounted displays 1 each having a virtual object acquisition unit 22 that acquires a virtual object, a display information acquisition unit 23 that acquires display information used to display the virtual object, and a display control unit 24 that causes a display unit to display the virtual object on the basis of the display information, and enables switching between of first display control for causing the virtual object to be displayed on the basis of display information acquired by each of the plurality of head-mounted displays 1 and second display control for causing the virtual object having an identical orientation to an orientation of the virtual object displayed on the basis of display information acquired by another head-mounted display 1 to be displayed.

A method and apparatus for outputting a three-dimensional (3D) image are provided. To output a 3D image, a stereo image is generated based on viewpoints of a user and rendered into a 3D image. Since the stereo image is generated based on the viewpoints of the user, the user views a different side of an object appearing in the 3D image depending on a viewpoint of the user.

A system may comprise a selectively transparent projection device for projecting an image toward an eye of a viewer from a projection device position in space relative to the eye of the viewer, the projection device being capable of assuming a substantially transparent state when no image is projected; an occlusion mask device coupled to the projection device and configured to selectively block light traveling toward the eye from one or more positions opposite of the projection device from the eye of the viewer in an occluding pattern correlated with the image projected by the projection device; and a zone plate diffraction patterning device interposed between the eye of the viewer and the projection device and configured to cause light from the projection device to pass through a diffraction pattern having a selectable geometry as it travels to the eye.

A virtual or augmented reality display system can include a first sensor to provide measurements of a user's head pose over time and a processor to estimate the user's head pose based on at least one head pose measurement and based on at least one calculated predicted head pose. The processor can combine the head pose measurement and the predicted head pose using one or more gain factors. The one or more gain factors may vary based upon the user's head pose position within a physiological range of movement.

According to one embodiment, an eye movement detecting device comprises first, second, third, fourth and fifth electrodes. A line connecting the first and the third electrodes passes through the right eye and a line connecting the second and the fourth electrodes passes through the left eye on at least one of a front view, a plan view or a side view. A distance between the fifth and the first electrodes is equal to a distance between the fifth and the second electrodes. A distance between the fifth and the third electrodes is equal to a distance between the fifth and the fourth electrodes. The detector respectively detects a horizontal movement of the right eye and a horizontal movement of the left eye.

The invent discloses a smart wearable device for vision enhancement and a method for realizing stereoscopic vision transposition, comprising a wearable device body, wherein the wearable device body is provided with camera lenses, image sensors, an image information receiving and transmitting unit, image enhancement units, and near-to-eye optical systems; the optical axis and field angle of the near-to-eye optical system are matched with the optical axis and field angle of the camera lens; the image sensor is arranged behind the camera lens; the real scene enters the image sensor through an image imaging device for image acquisition, and through the image enhancement unit, the low-light environment image collected by the smart wearable device in the low-light environment is enhanced and displayed clearly. The invention can ensure the enhancement of the real stereoscopic vision in the dark environment and the interchange of the remote and barrier-free stereoscopic real vision.

A head-up display includes a display panel, a reflective optical element, a controller, and an obtainer. The display panel displays a first image. The reflective optical element reflects image light from the first image displayed by the display panel. The controller controls a position at which the first image is displayed on the display panel. The obtainer obtains, as positional information, a position of an eye of a user. The controller changes the position at which the first image is displayed on the display panel in accordance with the positional information.

A head-up display is mountable on a movable body, and includes a first display panel, a reflective optical element, and an optical member. The first display panel displays a first image. The reflective optical element at least partially reflects image light from the first image displayed by the first display panel toward a user of the movable body. The optical member is between the display panel and the reflective optical element and is light transmissive. The display panel includes a surface facing a surface of the optical member. Each of the surface of the display panel and the surface of the optical member includes a reflection reduction layer to reduce light reflection.

A head-up display system includes a first projection module that projects a first image to display the first image in a forward direction not directly facing a user, a second projection module that projects a second image to display the second image in a forward direction directly facing the user, and a reflective optical element that reflects at least a part of the first image and at least a part of the second image.
