Recently, Advanced Driver Assistance System (ADAS), such as Autonomous Emergency Braking (AEB), Adaptive Cruise Control (ACC), have been widely used. In the future, autonomous driving is going to spread. Autonomous driving is doing research and development in present. When ADAS does not work for some reason, drivers are required to understand immediately what states of ADAS is in. Take over driving operation must be as soon as possible. Visual interface enables us to understand the states of ADAS. It is important for driver to understand the visual image to take over driving operation appropriately. In this paper, we compared traditional visual interface and new one. The traditional visual interface is constructed by symbols that indicate the states of the system, ON/OFF. On the other hand, the new visual interface is constructed by “avatar symbols”. Experimental studies using driving simulator showed the effectiveness in the driver’s brake operation, such as braking position and maximum deceleration.
