perception of distance in virtual reality environments

In order to be genuinely multi-dimensional, the imaging component of a Virtual Reality system must create the sensation of depth and three-dimensionality. One way to create depth perception is achieved using the shape of an object's edges. An object's outer edges form its outline. When an object's outline overlaps over that of another object, then it is thought to be closer than the other object. In like manner, if the outline is bigger compared to a second object believed to be of similar magnitude, then it is seen as closer than the second object. Lastly, when an object moves a longer distance in reaction to head movement than other elements or the background setting, then it is seen as closer. Similar VR coverage at For Better Software .

Eventually, computing systems might be able to model a virtual three-dimensional model of one's body right away by combing pictures from several video cameras in like manner to how one's brain puts together pictures from two eyes, but human sensation is neither simple nor easy to duplicate. Although humans have adapted to handle objects that go out of the direct line of vision, are dimly lit, or are challenging, such conditions challenge optical tracking by current computers. With future development, computing systems may be better able to create 3D models from optical images, creating opportunities for better optical monitoring of body movement.
