sight, hearing, and touch in virtual reality

In order to really attain sensory immersion of a human inside a virtual reality setting, the Virtual Reality (VR) system should involve vital sensory methods in a believable manner. The critical senses by which humans receive information concerning their environment are vision, hearing, and touch. Accordingly, these are the main elements of current VR systems. If sensory signals from these things is haphazard, then immersion will not be reached. For example, response lag between location determination by the inner ear and position determination by vision will detract from the sense of involvement in a realistic world. In a similar fashion, delays or gaps between touch and hearing or between vision and hearing also create difficulties. Such delays cause disconfiguration and nausea.

Many cues for 3D perception come from interaction among things. Key features of these communications are overlap, scale, and parallax. Objects that overlap on top of other objects are seen to be nearer. Objects thought to be alike in actual size but appearing bigger are perceived as closer and objects that grow in apparent size are seen to be moving nearer. Objects that shift a more distance in comparison with other things when one's head moves are perceived as closer. See related material at Virtual Tours Corpus Christi, Texas .
