Building a cognitive model of tactile sensations based on vibrotactile stimuli

We investigated the correspondence relationship between vibrotactile stimuli and tactile mental imagery using a vibrotactile glove proposed in a previous study as an interface for vibrotactile stimuli [1]. The mental impressions of the vibrotactile stimuli obtained by the human subjects were measured using the semantic differential method. Analysis of variance, multiple comparisons, and factor analyses were used to extract and evaluate the distinctive imageries induced by passive touch, based on the answers of the subjects to certain questions. To build a cognitive model of tactile sensations, we investigated the correspondence relationships between tactile sensations and vibrotactile stimuli.
