DYNAMICS OF THE EYE AND HEAD DURING MOVEMENT BETWEEN DISPLAYS: A QUALITATIVE AND QUANTITATIVE GUIDE FOR DESIGNERS

The purpose of this paper is to provide a designer or systems analyst a guide to human performance limitations in vision when fixation must be redirected from one display to another. Perhaps the most universally appreciated example, in the United States at least, would be the visual dynamics involved when driving an automobile and merging from an on-ramp onto a busy freeway. The time required here to move visual fixation from ahead, back to a possible traffic gap, and to return will often exceed the time gap to the vehicle ahead. The focus is on large angular separation (greater than 20 deg) and on tasks wherein speed is of importance. Patterns of eye and head movements are shown, as well as quantitative data on saccades, periods of eye/head compensation, and head movement. Independent variables include interdisplay angle, display visibility, operator's knowledge of display location, and some relevant characteristics of a possible task which must be interrupted for the refixation. Intersubject and intrasubject variability are also presented.
