Fatigue Driving Detection detects the driver's fatigue state by identifying the facial expression with the front camera of the mobile phone. It can detect actions such as closing eyes, blinking, yawning, looking left and right, wandering, etc., and send out a reminder when the driver is tired to drive to ensure safe driving. At the same time, the app also has the alarm function, which is divided into three periods: 0-1 hour, 1-3 hour and after 3 hours. Each period can be set with different reminder intervals.
