Distance Estimation Training with Night Vision Goggles Under Low Illumination.

Abstract : Aircrews have reported significant problems in depth perception and distance estimation with night vision goggles (NVGs). The purpose of this experiment was to examine the value of a simple training procedure as a means of reducing errors. A pre/post-test design was used in which distance estimates for a training group and control group were compared. The results revealed significant reductions in errors and variability following exposure to the training procedure. No significant reduction in errors and variability occurred with the control group. These results are consistent with a preliminary experiment using NVGs and earlier research using unaided vision. Issues for future research are also addressed.
