the boundaries of virtual reality

When a human engages with a 100% enveloping, artificially-generated setting, this is definitely within the realm of Virtual Reality (VR). Nonetheless, this is it virtual reality when a human interacts with the physical world with the assistance of selected virtual things or implements? For instance, is it virtual reality if a pilot uses computer-constructed diagrams overlaid on the sky to direct travel, a physician uses virtual images overlaid on a patient's body to operate, or an oil driller uses virtual pictures superimposed on the earth to direct oil drilling? These applications are examples of "Mixed Reality" (MR). Mixed reality is less than 100% enveloping and artificially-generated. These uses raise the issue as to what portion of computer generated parts is the boundary between pure Virtual Reality (VR) and mixed reality ...10%?...50%? ...90%? Based on where you make the cut-off -- a modern real-world setting including cell phones, e-mail messages, car direction systems, palm tops and similar machines may be seen, taken together, as a mixed reality environment.

Many cues for three-dimensional perception come from interaction among things. Key characteristics of these interactions are overlap, scale, and parallax. Objects that overlap over other objects are perceived as closer. Objects believed to be alike in magnitude but seeming larger are perceived as nearer and components that grow in apparent size are perceived as travelling nearer. Objects that shift a more distance relative to other objects when one's head moves are perceived as nearer. Further information on virtual reality at Virtual Tours Oklahoma City, Oklahoma .
