Abstract

This study investigated the hypothesis that a lateral shift in the direction of an operator's orientation (looking to the left or looking to the right) will facilitate processing in the cerebral hemisphere which is contralateral to the direction of the orientation shift. In view of the specialized functions of each hemisphere, it was hypothesized that displays with “verbal” content would be best located 20° to the right of center and displays with “spatial” content would be best located 20° to the left of center. A laboratory study was conducted to test this theory. The results support the idea that lateral eye-gaze orientation shifts influence hemispheric processing, implying that this phenomenon may be a consideration for selectively locating complex visual displays.
