Abstract
Visual workload while driving is increasing because of the growing amount of information presented to the driver by a high-functioning onboard unit. A method of HMI to intuitively understand hazards without visual information is necessary. In this study, we focused on tactile sensation. The movement of surrounding objects was transmitted to the driver through a steering wheel using vibrotactile apparent motion. Firstly, we confirmed the highly intelligible characteristics of front-to-back, right-to-left, and back-to-front movements while holding a steering wheel. The direction of movement was transmitted using highly intelligible characteristics, and a positive effect was confirmed.
