Evaluating visual search performance with a multi layer display

- 08 Dec 2008

- pp 307-310

TL;DR: It is found that placing distracters and targets on different depth layers can significantly improve performance in complex search tasks.

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.

TL;DR: The authors show that the response times are considerably more influenced by the target/distractor combination than by the attentional search paradigm deployed, and found that error rates are considerably higher in covert search.

TL;DR: This work has shown that a stereoscopic label placement algorithm yields user performance comparable with existing algorithms that separate labels in the view plane, and is subjectively rated significantly less disturbing than traditional methods.

TL;DR: Three experiments test the claim that conjunction search is difficult only because the target resembles each distractor, whereas the distractors are highly discriminable from each other, and results show that when similarity is controlled, there is an additional difficulty created by the need to conjoin features.
