Holographic Virtual Reality

Vision is the dominant human sense and the most challenging aspect for creators of virtual reality applications. Although a three dimensional, immersive field of vision can be simulated by goggles, they can cause nausea and lagged responses to head motion. Holographic technology can create more natural three- dimensional visual environments. One method for information transferral from humans to computers is "computer vision" wherein high-order processing of camera pictures of human motion via computer allows the computer system to distinguish vital patterns and gestures of human movement. In any event, this technology has limitations. The relevant portions of one's body must all be in view of the camera. They must not be hidden by things in the environment or by rest of the human body. Some gestures are overlapping in themselves. This approach is also limited by lighting conditions. the scope of human senses involved in virtual reality covers more information along these lines.

Virtual reality can also be a tremendous aid for design in the areas of engineering and manufacturing, building design and construction, biotechnology and nanopharmacology, chemistry and modeling molecules, medicine and bionics, the clothing sector, and the fine arts. Three-dimensional models of molecules and biological structures can be assembled and handled virtually. Electronics may be fabricated and tested absent creation of a physical model. Virtual modeling clay can be shaped into different forms for either aesthetic or functional purposes. Link to virtual trade for more on VR.

If you wanted to specify the sum of human sensory potential for communication from world to human and total modality output for interaction from human to setting, then one could identify a threshold percentage that one expects to be activated by computer simulation to meet the qualifications of Virtual Reality (VR), but quantifying sensory bandwidth and summing communication potential across different senses and mechanisms is a challenge. A different method to specify the base-line amount of communication between humans and computers to be categorized as Virtual Reality is the "four i's" approach. Virtual reality must be (1) engaging, (2) enveloping, (3) immediate, and (4) high-performance. three-dimensional perception in virtual reality settings discusses additional information about these concepts.

Virtual reality is a computer-created world inside which multiple people can connect with things three dimensionally while engaging sight, sound, and (in some measure) touch and locomotion. The sense of believability in this type of environment increases with: (1) greater scope and depth of sensory bandwidth actively involved in the human to computer interaction (e.g. amount of range of sight, clarity of visual pictures, quality of sonic communication, quantity and degree of body members actively involved in locomotor and haptic interaction); and (2) more quickness and intelligence of the human to computer communication, such as as the behavior of computer-generated components more closely conforms to the scientific principles that govern their real-world equivalents. Differences from the latter arise for fantasy world uses. In any event, even for those applications the difference from realistic dynamics should be managed to make a sufficient sense of reality for the human to be genuinely engaged. If the setting is too surreal, then believable interaction fails. characteristics of augmented reality also has interesting notes on this topic.
