Abstract

This paper investigates the influence of hands-free device on the braking operation of drivers. In the driving simulator experiment, participants performed a simple driving task and talking task with four types of hands-free device. When participants recognized the cautionary voice of fellow passenger, they braked as soon as possible. We developed the measurement system to evaluate reaction time, which is from the generation of the cautionary signal to the beginning of braking. As a result of calculating the mean of reaction time, the smallest was the non-talking condition, followed in order by the bone conduction headset condition, the earphone headset condition, and the speaker condition. Moreover, there are significant differences between hands-free devices by one-way analysis of variance. In addition, the Shaffer's multiple comparison showed that some comparisons differed significantly. It is suggested that the bone conduction device has less influence on the delay of the brake pedal operation.
