Evaluating visual search performance with a multi layer display

Abstract

A Multi Layer Display (MLD) is a novel device which allows content to be shown on different depth planes. Earlier research indicates that stereoscopic depth information can be beneficial in visual search tasks. This has not yet been explored for this new display technology. In this paper we present the results of an experiment to explore how the actual depth information afforded by a two layer MLD affects visual search task performance. We found that placing distracters and targets on different depth layers can significantly improve performance in complex search tasks. We discuss these findings and provide suggestions on how to arrange the stimuli across the two layers in order to get the full benefit of the depth information.
