Abstract
The Canadian Forces have recognized the importance of simulator training as a cost-effective alternative to real training; yet the effect of display simulation on visual perception is not fully understood. Eighteen subjects participated in an experiment to determine if training, in the form of immediate feedback, improved distance estimation to muzzle flashes in a simulated NVG environment. Testing was performed on a PC desktop computer using software that simulated a large open grassy 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. Significant improvement was shown in the experimental group’s accuracy; this accuracy persisted over two weeks but with notable deterioration. Contrary to expectation the perception of a single flash resulted in significantly greater accuracy than the prolonged flash. This experiment reinforces the effectiveness of simulation as a tool in preparing soldiers. A bibliography of the topic is included.
