virtual reality and the dynamics of human vision

Human sight sensation includes foveal, parafoveal, and peripheral vision. Foveal vision is the center of one's field of vision and gives the highest image resolution and focus. Image accuracy drops off as one moves from the foveal field to the outer portions of the parafoveal field. In any event, human beings have tremendous sensitivity to motion, even for their peripheral vision. When computer performance to make 3D images in a virtual world is limited, Virtual Reality systems can build upon this structure in human sight perception. They can lead to pictures with greater resolution in the central focal area of a person's range of sight. Such systems must also be able to alter picture resolution rapidly in reaction to head motion. VR++ also has interesting notes on this virtual reality topic.

Computer recognition of hand configurations and facial expressions currently happens and will likely lead the development of optical information transmission from humans to computers. Gesture interpretation is based on computer processing and three-dimensional modeling of the structure and movement of the human hands and face. This puts together conceptual elements from anatomy, kinesiology, and human vision. Human body language can be recorded through a computer directly through a mechanical glove or indirectly via the optical processing of video images. There is considerable potential for advanced development of optical measurement of lip, facial, eye, head, hand, and body movement. Several challenges remain. Computers cannot currently track components that are hidden from the line of vision by other elements, poorly lit, or too challenging. Future generation formation of methods to translate optical images into virtual three-dimensional things should open the door for much more precision in optical monitoring of human movement.
