Objective: The aim of this study is to investigate the drowsiness awakening effect of automotive ambient light beyond its original aesthetic role. Background: Drowsy driving is a severe social problem that causes many car crashes and casualties annually. As the self-driving car industry is revitalizing, the market size of ambient light is also growing bigger, led by luxury vehicle brands. Method: The experiment was conducted in a simulator environment that mimics a vehicle that is autonomously driving on a highway, and 15 healthy men and women between their 20s and 40s who do not have excessive daytime drowsiness tendencies were selected as subjects. During the experiment, the subject evaluated the subjective state of drowsiness by citing the Stanford Sleepiness Scale (SSS) in 2-minute intervals. The color, illuminating pattern and frequency (ambient light scenario) are changed when the sleepiness scale cited by the subject is 5 or higher. The drowsiness state of the subject was measured by PERCLOS extracted from the eye tracker signal and SSS. The arousal effect of the ambient light is verified through Paired t-test. Results: The PERCLOS was analyzed between the group that experienced the change of illuminating scenario and the group that did not. The Paired-sample t-test results t = 4.54, significance probability p<. 001 showed statistical significance between the two groups. Conclusion: The Ambient light control has been proven effective in preventing driver drowsiness. Application: The results of this study suggest the direction of developing UX technology that combines driver monitoring and ambient light.
