virtual reality and the dynamics of human vision

Human vision perception spans foveal, parafoveal, and peripheral vision. Foveal vision is the center of one's cover of vision and gives the highest picture resolution and focus. Image accuracy drops off as one goes from the foveal field to the non-central areas of the parafoveal field. In any event, people have tremendous responsivity to movement, even for their peripheral vision. When computing power to make three-dimensional images in a virtual setting is limited, Virtual Reality systems can take advantage of this design in human sight sensation. They can create images with more resolution in the center of vision of a person's range of sight. Such systems also should be able to adjust image resolution rapidly in response to head motion. The VR-interesting site Virlink is also of interest.

Virtual Reality (VR) is an immersive artificially-generated setting inside which someone can perceive and handle things three dimensionally, right away, and in a manner similar to human interaction with things in the real world. Interaction with things in virtual reality can vary by range. Range considers the number of sensory mechanisms (vision, hearing, touch, etc) and control methods (e.g. body motion, voice recognition, etc.) that are used. This communication can also vary concerning comprehensiveness (e.g. range of vision, sound range, range of body touch sensation, etc.) and resolution (precision of sight, hearing, body movement, etc.).
