Glossary » binocular display

binocular display

also stereoscopic display; a display that is composed of 2 separate displays which are directed separately to the left and right eyes. The viewpoint is slightly different for each, reflecting the slightly different view each eye would have when embedded in a 3D scene, thus allowing for a sense of depth. Binocular displays are used in virtual reality systems and any 3D system for which depth cues are especially important. Because the displays are usually up close to the eyes, they often also extend across a wider visual angle in the eye, allowing for a greater sense of realism, and in the extreme, allowing for the use of peripheral vision.
