A system is described which can record operator head movements in a reliable, economical and unobtrusive manner under operating conditions. The system will be used to determine the patterns of visual search and their effects on operator performance. The goal is the improvement of existing design at the man-machine interface in vehicle cabs in order to reduce visual fatigue. This fatigue of the ciliary (accommodating) muscles of the eye results in prolonged reaction times, slowing of control movements and other disturbances. EMG biopotentials from the dorsal neck region are processed and used to trigger the intervalometer of a high quality Super 8 movie camera on a discrete frame-by-frame basis.
