Do colors affect our recognition memory for haptic rough surfaces?

Abstract

Haptic (tactile) interaction is a promising approach to be used for human computer interfaces. But how various kinds of haptic effects are learned and memorized, and what factors might influence user performance, remain unanswered. Little is known about the recognition memory for haptic information. The authors used a recognition memory paradigm to study the influence of color information on recognition memory for haptic rough surfaces. Participants' performance is less confident at exposure duration of 2s than at other three durations. The performance shows little difference as long as rough surfaces are presented and queried in the same color. However, Experiment 2 revealed that the influence of colors on haptic memory is sensitive to color presentation and query conditions. Our results can be used as guidelines for haptic interfaces for selecting colors. © Springer-Verlag 2004.
