An automotive warning presentation system with vibrotactile device was evaluated with an empirical study. Young and older adults participated in the experiment. The participants were required to simultaneously carry out a tracking task, a switch pressing task such as a selection of light-off, and a judgment task of information which randomly appeared on the front or the rear. The vibrotactile device was located at their arms, legs, and stomach/back. The vibrotactile stimulation was presented as apparent movement and single-point vibrotactile stimulation. It was confirmed that the vibrotactile warning was effective for both young and older adults. As for young adults, the stimulation location did not affect the performance measures such as the reaction time to dangerous situations. On the other hand, concerning older adults, the stimulation to the leg led to better performance such as the reaction to dangerous situations irrespective of the method of warning presentation.
