Abstract

The present aim was to study emotion-related evaluations of piezo actuated haptic stimulations. We conducted three experiments where the presentation type (i.e., haptic only, haptic auditory, and auditory only) of the stimulus was varied. The participants' task was to rank which of the two sequentially presented stimuli was more pleasant and which was more arousing. All pairwise comparisons were created from 9 stimuli varied by rise time (i.e., 1, 3, and 10 ms) and amplitude (i.e., 2, 7, and 30 µm). The results showed that in general the haptic only and haptic auditory stimuli were ranked as more pleasant and arousing than the auditory only stimuli. In addition, the results suggest that the stimuli with long rise times can be seen as more applicable than the stimuli with short rise times as they were in general ranked as more pleasant and arousing.
