Presentation
Comparing Intensity and Location-Based Tactile Change Detection Performance
SessionPP3: Tactile Displays
DescriptionTransmitting information in the tactile channel is a promising solution in complex domains because it can offload the often oversaturated visual and auditory channels. While the tactile modality is a promising means of presenting information, the phenomenon of change blindness, or the failure to detect changes between stimuli, has been repeatedly demonstrated in the tactile modality. No study to-date has directly compared location (i.e., when there is a change in the location of the tactile cue) and intensity-based (i.e., when there is a change in tactile cue intensity) tactile change detection. The present study uses a simple stimulus apparatus of 10 mechanical tactors on the fingertips to examine whether changes in location and intensity can be considered equally susceptible to change blindness. While location-based changes were more discriminable, they were responded to significantly slower than intensity-based changes. The observed outcomes could have serious consequences in safety-critical domains.
