Abstract
The driving support systems using road or vehicle communication are studied. The HMI (Human Machine Interface) to inform the driver is very important for these driving support systems. In this paper, we examined a display position and method experimentally assuming some driving support systems with vehicle communication. As a result, we understood that oversight of display on navigation position and meter position increased while the driver is waiting to right turn. In addition, we clarified reaction time for a display position and subjectivity evaluation such as happiness for display. And we suggested the evaluation method to estimate an appropriate display position and method from reaction time and subjectivity evaluation.
