The Effect of an Eye Movement Recorder on Head Movements,
Abstract
The present study had two major objectives: (1) to detemrine whether the NAC Eye Mark system alters the normal pattern of subject head movement in a typical simulated helicopter piloting tasks; and (2) to obtain subjective evaluations from subjects while wearing the NAC eye mask concerning field of view, acuity, comfort and safety. Concerning the analysis technique, it was shown that the measurement of total movement of the subjects head could be reliably accomplished with the equipment and method used. The unmodified NAC eyepiece was found to cause significantly more head movement in IFR flight than a no mask condition. It was also demonstrated that an NAC mask with the lower horizontal section removed and semi-silvered lenses on both eyes did not differ significantly from the no mask condition in terms of head movements; in contrast, the unmodified Mark I mask was the preferred choice of the subjects since the eye pieces did not cause eye fatigue with the lighting conditions in the simulator. Subsequent work has shown that in actual flight conditions, the Mark II mask was preferred, since the increased light levels of actual flight alleviated the problem of eye fatigue.
