Distance Estimation and Simulation Training

An experiment was conducted to determine how feedback training affects distance estimation, in simulation. Eighteen subjects participated in this experiment and training was conducted using a night vision simulation of an original scene. Testing was performed on a PC desktop computer running VegaPrime to simulate light source halos in an open field. Subjects were exposed to three flash types; five flashes, single flash, and a prolonged flash. Flashes were presented to the subjects both above and below the horizon. There were significant improvements for the group that received feedback training; their accuracy in distance estimation persisted for two weeks, but with some deterioration in scores.  Immediate feedback is an effective training technique, but simulation software must be realistic in reproducing the gamut of depth cues for naturalistic environments for effective training.
