Abstract/Summary

In this study we explore whether inclusion of monocular depth within a pseudo-3D picture gallery negatively affects visual search strategy and performance. Experimental design facilitated control of i) the number of visible depth planes and ii) the presence of semantic sorting. Our results show that increasing the number of visual depth planes facilitates efficiency in search, which in turn results in a decreased response time to target selection, and a reduction in participant average pupil dilation – used for measuring cognitive load. Furthermore, results identified that search strategy is based on sorting, which implies that appropriate management of semantic associations can increase search efficiency by decreasing the number of potential targets.
