Abstract

The goal of this study is to build a system to prevent a driver from becoming a dangerous state such as a drowsy
driving by detecting and resolving a driver's absentminded state and drowsiness using vehicle equipments. In
experiment 1, we have developed detection algorithm using vehicle speed and steering angle, and verified the accuracy
of the algorithm using 34 driving data measured under the actual driving environment. As a result, detection accuracy
was 82%. In experiment 2, we compared five-sense stimulation including display image change, sound change and air
blowing, and active coping including utterance, exercise and finger movement. The effect of resolution methods was
evaluated through subjective evaluation and facial expression rating score. As a result, it was suggested that the
methods based on active coping had higher effect than the methods based on five senses.
