Eye and Head Response to an Attention Cue in a Dual Task Paradigm.
Abstract
Eight subjects were used to characterize eye and head movements in response to a cue to refixate in a dual task paradigm. The subject's tasks were complete a centrally located pursuit tracking task and identify targets which were vertically displaced from the normal line-of-sight. Reaction time and movement pattern of the eye and head were recorded as well as conventional performance measures for the following: 1) two difficulty levels of the tracking task; 2) presence and absence of an attention cue prior to target presentation; and 3) two target locations which were vertically displaced from the centrally located task. The results indicated that eye and manual reaction time increase the farther a target is vertically displaced from the centrally located task and head reaction time decreases with the presence of a verbal cue prior to target presentation. Since the experimental conditions examined in the present study affected these measures differently, eye, head, and manual reaction times should be examined further. The differences found in eye and head response as a function of information location and presence of an attention cue suggest that such unobtrusive measures may be valuable in the design of multifunction display symbology and attention cueing systems.
