Human characteristics of figure recognition in tactile feedback

Abstract

In car, information presented to drivers is increasing and most of information is done using the visual and auditory displays. Presenting the information only to visual and auditory modes must cause drivers’ cognitive overloads in the near future and it is necessary to find the way using other modes to reduce them. In this study, we especially focus on human tactile figure recognition of the train of sticking stimuli and examine the human characteristics of what kinds of figures people can recognize as the tactile feedback. We developed tactile device that expresses four figures. We found there are interactions between the interval time of each sticking and the figures and human has quite different mechanisms between the cases of the simultaneous sticking and the consecutive sticking in recognizing the figures.
