Abstract

We examined the effects on human 3D tracking perfor_mance of several common defects of immersing virtual environments: spatial sensor distortion, visual latency and low update rates. Results show: 1) Removal of rela_tively small static distortion had minor effects on tracking accuracy, 2) An Adapted Cooper-Harper controllability scale proved the most sensitive subjective indicator of simulation degradation, and 3) RMS tracking error and subjective impressions were more influenced by changing visual latency than by update rate.
