Description

<p>Designing haptic stimuli is one of challenges to enrich the virtual reality experience through a head mounted display which offer a photorealistic visual stimuli. Although exaggerated non-photorealistic haptic stimuli are widely used to represent events in virtual world due to limited capacity of haptic interface, the evaluation of its plausibility relies on human subjective assessment. The purpose of this research is to establish a method to objectively evaluate the plausibility of such visual-tactile experience. This study designs a stroop task in which participants are asked to tap an object with a stylus, receive visual stimuli (texture) and tactile stimuli (pulsive vibration) at a time, and respond to answer tactilely felt stiffness (soft or stiff). Our hypothesis is that response time to the stimuli consisting of incongruent visual and tactile combinations (soft-stiff or stiff-soft) becomes longer than those consisting of congruent combinations (soft-soft or stiff-stiff) if the tactile stimuli are felt so plausible as to interfere visual-tactile experience. The results of the experiment indicates the stroop effect, which supports the hypothesis.</p>
