Fatigue accumulation and poor attention could cause accidents in situations such as flight control, and automobile operation. This has contributed to international interest in intelligent transport system (ITS) research and development. We evaluated human sleepiness arousal based on facial thermal image analysis, in doing so based on nasal skin temperature for different levels of sleepiness during vehicle driving, we found that nasal skin temperature can replace facialexpression in evaluating sleep transition.
