Abstract
This study evaluates the effects of a vibrotactile (or haptic) accelerator pedal on car driving performance and perceived workload using a driving simulator. The stimulus was triggered when the driver exceeded a 50% throttle threshold, past which is deemed excessive in the literature. Results showed a significant decrease in mean and maximum acceleration values, also a reduction in the maximum and excess throttle values when the haptic pedal was active versus a baseline condition. In addition, a further decrease in maximum and excess throttle was observed compared to when participants were simply asked to drive economically. As well as the positive changes to driver behaviour, subjective workload decreased when driving with the haptic pedal. The haptic processing channel offers a largely untapped resource in the driving environment, and could provide information without overloading the other attentional resource pools used in driving.
