Correspondence relationships between vibrotactile stimuli and tactile sensations determined by semantic differential

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 human subjects were measured by semantic differential. 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 given to questions the subjects were asked. We also discuss the potential of the glove to produce the five fundamental sensations of fine roughness, macro roughness, hardness, warmness, and friction.
