Head Aiming/Tracking Accuracy in a Helicopter Environment.

Abstract

This experiment was conducted to measure man's head aiming/tracking capability using a helmet mounted sighting device. The influences of target speed, helmet suspension types, and helmet weighting parameters on head aiming/tracking were investigated. If the aiming/tracking accuracy was sensitive to manipulation of these man-machine interface parameters, then it would seem to indicate that improved aiming/tracking accuracy could be obtained by improving the interface. The factors analyzed were eye dominance, helmet weighting, target speed, and helmet suspension. The eye dominance, helmet weighting, and target speed factors were statistically significant; however, the only factor of practical significance was target speed. A subject aiming at a static target with his head had an RMS error of about 3 milliradians. Then the target began to move 4 degrees/second, the error increased to about 10.5 milliradians. When the subject began to vibrate too, the error increased to 13 milliradians. When the target speed doubled, the vibrating error increased to 16.8 milliradians. (Author)
