文摘

This study investigated the influence of multipoint vibrotactile stimuli on the basis of propagated vibration on the perception of collision sensation through two experiments. In the first experiment, we measured the vibration waveforms generated by a tennis ball hitting at the gripped racket, wrist, and elbow. The measured vibrations on the three positions displayed different profiles and frequency spectra, which appeared to be caused by the vibration propagation. In the second experiment, participants evaluated the vibrations reproduced on the basis of the measured vibration in terms of the display conditions using subjective evaluation. The results showed that multipoint vibrotactile stimuli improve the magnitude and size of area of collision sensation compared with a single-point vibration, and the unnatural condition in which multipoint stimuli containing recorded and unrecorded waveforms degraded the reality of reproduced collision sensation.
