advances in computer responsiveness in virtual environments

To be engaging, a world should react to one's action with a sufficiently great level of appropriateness and speed to provide a participating human a sense similar to communication with real world things. With current technologies, this usually involves achieving a certain amount of computer response to the position, motion, and configuration of the participating person's eyes or head and that of at least one hand. Computer reaction to the location, angle, and direction of the rest of the participating human's body is vital. In any event, this is not currently included in the minimal specification for virtual reality. This also will change as applied science advances.

Computer interpretation of hand configurations and facial expressions currently happens and will likely lead the development of optical human to computer communication. Gesture recognition is built on computer operating and 3D modeling of the structure and motion by the hands, arms, and face. This puts together conceptual elements from anatomy, kinesiology, and human biovisual processing. Human body language can be measured via computer via a mechanical glove or indirectly via the optical analysis of video pictures. There is considerable potential for further formation of optical measurement of lip, facial, eye, head, hand, and body movement. Several challenges remain. Computers cannot currently track things that are obscured from the line of vision by other objects, poorly illuminated, or too challenging. Future development of methods to convert optical pictures into virtual three-dimensional things should open the door for much more accuracy in optical monitoring of body movement.
