Datenhelm
The higher the processor’s performance, the more realistic the simulation. A camera mounted in the environment’s wall photographs the users eyes. These images are evaluated by an eye tracker, and the results are fed to the processor as picture coordinates. The computer continuously recomputes the graphic display so that the virtual world constantly conforms to the user’s point of view. The virtual environment reacts within a fraction of a second to the actions and the perspective of the user. Data glasses and data glove make this encounter with computer-generated environments possible in a way that would be impossible with mouse and keyboard alone.
