Autostereoscopy is any method of displaying stereoscopic images -LRB- adding binocular perception of 3D depth -RRB- without the use of special headgear or glasses on the part of the viewer .. stereoscopic. stereoscopy. binocular. binocular vision. Because headgear is not required , it is also called `` glasses-free 3D '' or `` glassesless 3D '' .. There are two broad approaches currently used to accommodate motion parallax and wider viewing angles  : eye-tracking , and multiple views so that the display does not need to sense where the viewers ' eyes are located .. Examples of autostereoscopic displays technology include lenticular lens , parallax barrier , volumetric display , holographic and light field displays .. lenticular lens. lenticular lens. parallax barrier. parallax barrier. volumetric display. volumetric display. holographic.
