Analysis of Spatiotemporal Memory Using Air-Jets as Tactile Stimuli for Development of Noncontact Tactile Displays

The effects of delay and distance of a pair of tactile stimuli on the memory of the two locations were analyzed. Tactile stimuli were induced at the palm with seven levels of interstimulus distances and seven levels of interstimulus intervals. The results showed that the smallest two-point differential threshold was when the delay time was around 0.5---2.0 s. The fundamental characteristics associated with spatiotemporal tactile memory that were obtained in the present study can lead to the design of a noncontact tactile display.
