simulation adaptation syndrome

Eye focus conflict and virtual picture response lag can cause eye strain, disconfiguration, nausea and even long-run health problems. These effects are "Simulation Adaptation Syndrome" or SAS. Females tend to experience more SAS than males. People can become used to virtual reality to some extent. Similarly, SAS is usually less severe when people experience multi-dimensional Virtual Reality (VR) bit by bit by means of several sessions. The sessions start out only a couple minutes long and then gradually grow in duration, with real world intermissions between sessions. With technology now available it is a challenge to avoid these problems, but these problems may eventually be significantly reduced by evolving technologies such as: external imaging systems with variable distance imaging (such as (half) spheres with multiple layers of translucent screens), holographic imaging (with 3D pictures projected in mid-air), or internal body imaging (projecting images onto the retinas or direct neuroelectric transmission from a computer to the optic nerve or neural centers in the brain.)

Optics can also serve to track our motion. An elementary method of optical tracking involves fastening multiple light sources to a hand device or body tights and then monitoring their movements in three-dimensions. Nonetheless, this only tracks a few points. Gesture interpretation by computing systems is already underway. This involves computer modeling of the configuration of one's hands and face -- integrating concepts across the fields of anatomy, kinesiology, and human visual processing. The site on Virtual Tours Colorado Springs, Colorado covers more information along these lines.
