Abstract:

Past studies involving latencies of the eye and head have typically been confined to refixations along the horizontal periphery, with only limited data available involving the vertical periphery. Of the existing data involving the vertical periphery, most have been characterized by target displacements of less than 20 degrees with scarce head latency data. The present study was conducted as a logical follow-on to these studies by providing both eye and head latency data for refixations involving the horizontal and the vertical peripheries. Utilizing a helmet mounted oculometer and helmet sight system, response latencies, as well as patterns of eye and head movement, were investigated. The subjects performed a central ongoing manual tracking task while periodically receiving visual cues to classify letters on one of four peripheral monitors.
