Subjects immersed in a virtual room tracked an irregularly moving cube with a cursor that was controlled by their hand position. The response latency and frame rate of the system was varied. Objective tracking accuracy was compared with subjective estimates of controllability, realism, pain and disorientation. Results show that latency had a stronger effect on performance than frame rate and that the more systematically defined subjective reports, especially an adapted Cooper-Harper scale, more closely correlated with tracking performance.
