perception of distance in virtual reality environments

To qualify as being genuinely enveloping, the display equipment of a VR medium must create the sensation of depth and three-dimensionality. One way to make depth sensation is reached using the shape of an object's outline. An object's outer edges form its outline. When an object's outline overlaps over that of another object, then it is seen as nearer than the other object. Also, if the outline is larger compared to another object thought to be of similar magnitude, then it is seen as closer than the second object. Finally, when an object moves a longer distance in reaction to head movement than other things or the background setting, then it is seen as nearer. Also see VR-related Adds Visual Impact .

As applications of virtual reality become reasonably priced and more common among the general public, the terms surrounding Virtual Reality (VR) will continue to evolve. One possibility is that the prefix "v" might become combined with different words to identify "virtual" in a similar way to use of the prefix "e" to designate "electronic" in online applications. To be specific, virtual applications in the area of real property uses may be abbreviated "vRealEstate" and virtual uses in the area of trade might be shortened "vTrade".
