Vibrotactile Stimulation to Change Velocity Perception in Automobiles

Abstract

Velocity perception is important in safety, traffic jam relaxation, and concentration and drivability enhancement while driving automobiles. This paper study the control of velocity perception by using vibrotactile stimulation. We have focused on vibrotactile stimulation since tactile stimulation can be reasonable and be privately given to a driver. First, the seat vibration is measured using an actual vehicle to discover available stimulation of changing velocity perception. The result shows the peak frequency clearly increases with the rise of velocity while the intensity roughly increases. Then we investigate the influence of intensity or frequency-shifted vibrotactile stimulation on velocity perception by using a driving simulator reflecting actual vehicle characteristics. An experimental result shows a possibility of changing velocity perception by using frequency-shifted vibrotactile stimulation.
