Abstract:
This paper evaluates the effectiveness of vibro-tactile notifications for motorcyclists under external factors. Although many car manufacturers provide side and rear collision warning systems with auditory or visual alarms, such notifications may confuse a motorcyclist because they already need to be aware of many visual targets, such as mirrors and monitors, and of environmental sounds. We propose a vibro-tactile notification system using a vibration speaker installed in a motorcycle helmet between the outer shell and the cushion. The proposed system should enable motorcyclists to correctly identify the directions of five vibrating motors, three levels of risk, and three obstacle types (i.e., pedestrians, vehicles, and motorcycles). We evaluate the system under windy and engine vibration conditions and examine notification accuracy via experiment. Our results indicate that motorcyclists can correctly detect four directions and three threat levels using this system.
