5 - A Computational Model for the Stereoscopic Optics of a Head-Mounted Display

Abstract

For stereoscopic photography or telepresence, orthostereoscopy occurs when the perceived size, shape and relative position of objects in the three-dimensional scene being viewed match those of the physical objects in front of the camera. In virtual reality, the simulated scene has no physical counterpart, so orthostereoscopy must be defined in this case as constancy, as the head moves around, of the perceived size, shape and relative positions of the simulated objects.
