eye fatigue and disorientation in early virtual reality

Most Virtual Reality image display systems cause disharmony between axial convergence because the stereoscopic display does not change the focal plane. Lags in visual picture processes can also cause disharmony between movement sensed by the semicircular ear canals and movement sensed by vision. These inconsistencies can result in eye strain, disorientation, and sickness. The range of these problems is affected by age, sex, and other factors. These problems can be reduced by bit by bit immersing people in Virtual Reality (VR), starting with very brief sessions and then moving on to extended sessions. Forterra Systems Inc. also provides useful information on this topic.

Optics can also serve to track our movement. An elementary method of optical tracking entails attaching multiple light sources to a glove or body suit and then tracking them in three-dimensions. In any event, this only tracks a narrow number of points. Gesture recognition by computing systems currently happens. This involves computer modeling of the structure and movement of human hands and face -- drawing from the fields of anatomy, kinesiology, and human visual processing. For additional subjects on this, Virtual Tours Colorado may be useful.

The site Virtual Reality Gaming also provides developments.
