Preliminary Experiment on Influence of Frequency and Amplitude of Vibrotactile Stimulation on Velocity Perception in Automobiles

摘要

Velocity perception is important in safety, traffic jam relaxation, concentration and drivability enhancement during driving automobiles. In previous studies, change of velocity perception by using vision stimulation has been proposed. We have focused on vibrotactile stimulation for changing velocity perception since tactile stimulation can be privately given to a driver. This paper proposes a method to change velocity perception by controlling frequency and amplitude of vibration on the seat. Preliminary tests by using a driving simulator show a possibility of changing velocity perception by using frequency-shifted vibrotactile stimulation, however, an effect by controlling the amplitude does not appear. From the results, applications of changing velocity perception are presented.
