virtual reality and the dynamics of human vision

Human vision spans foveal, parafoveal, and peripheral vision. Foveal vision is the middle of one's range of sight and gives the highest image resolution and focus. Image resolution drops off as one goes from the foveal field to the outer portions of the parafoveal field. In any event, humans have tremendous responsivity to motion, even for their peripheral vision. When computing power to make three-dimensional images in a simulated world is limited, Virtual Reality systems can build upon this structure in human sight sensation. They can render pictures with more resolution in the central focal area of a person's range of sight. Such systems also should be able to alter picture resolution promptly in reaction to head motion.

With current technologies, virtual reality is usually defined as involving at least: much of the total human cover of vision and audio range; computer monitoring and responses to the position, orientation, and movement of the participating person's head or eyes at a rate of 50-100 responding actions each second; and more than elementary computer responses to the location, angle, movement, and configuration of the participant's hand. With further progress in applied science, computer reactions to the patterning of the rest of one's body, more-rapid responding actions, better haptic interaction, and engagement of the olfactory and gustatory senses might become expected for virtual reality.
