Dr. Michael McGreevy of NASA's Ames Research Center has taken the idea of being there a few steps further. By strapping on 3D visual display goggles and specially sensored gloves, one can be immersed into new worlds. What is unique about virtual reality is that the user has complete control over the environment. Head or body movements translate directly into the way a simulated martian landscape is seen. In another example, the task is to withdraw a square shape from its slot. The operator's glove can be manipulated to control a robotic arm, while sound cues help with depth perception and finding proper fit. Scientists have also designed a virtual wind tunnel. The investigator can move anywhere in the tunnel to study airflow. Virtual reality gives the operator complete choice, and is beginning to be used for a variety of commercial applications.
