Abstract:
This paper examines the robustness of our proposed haptic notification system against the different types and layers used for driving seat cushions. While many car manufacturers provide useful side and rear collision warning systems with sound alarms or visual monitors, the addition of similar notifications can confuse a driver because they already need to be aware of many visual targets such as mirrors, monitors, and environmental sounds. Therefore, we have investigated a haptic notification system that uses the driver’s buttocks. The results show that drivers can correctly identify the directions of five vibrating motors, three intensity settings, and three obstacle types (i.e., pedestrians, vehicles, and motorcycles). In this paper, we investigate whether drivers can discriminate the direction, intensity of vibrations, and vibration patterns of the system through their buttocks to identify the obstacle direction, degree of risk, and the type of obstacle, even if the vibrations are attenuated by the seat cushion. The results indicate the high potential of the haptic sensation system to notify the driver of obstacles, especially those located in the blind spot.
