perception of distance in virtual reality environments

To qualify as being truly three-dimensional, the display equipment of a virtual reality system must create the perception of detail and three-dimensionality. One way to make detail perception is achieved using the geometry of an object's edges. An object's outer edges form its outline. When an object's outline covers a second object, then it is perceived as closer than the other object. Also, if the outline is larger compared to a second object believed to be of similar actual size, then it is seen as nearer than the second object. Finally, when an object shifts a more distance in reaction to motion of one's head than other parts or the background world, then it is thought to be closer.

Communication from humans to computing systems built on movement happens via data entry pads, computer mice, gesture recognizing gloves, and other motion-detecting mechanisms. Since touch and motion are at the core of human-to-computer communication, Virtual Reality systems must have excellent methods for measuring motion by humans. They must track movement without interfering with it. Touch and motion based communication in the other direction, from the setting to humans, is also very important in the tangible world. However, as we will discuss, it is much less higher-order in virtual reality due to scientific constraints. Virtual Tours Cerritos, California also has related material.
