With the development of intelligent driving assistance technology, a great number of innovative electronic products and technologies are used to improve driving safety and fatigue reminding, such as face and eye movement recognition technology, and driving trajectory deviation monitoring and warning technology. Through the man-machine interaction means, the driver is reminded to pay attention to safe driving by using interaction forms such as smell, sound, vibration, light flicker and the like.
The emergence of wearable technology has made intelligent safety-assisted driving technology based on physiological data monitoring possible. The main difference between the physiological data detection technology and the intelligent identification technology lies in the unpredictability of data and more direct feedback of objective data indexes of a detected person. The heart rate fatigue monitoring technology is widely applied to the field of scientific research, and the data acquisition method is simpler than the intelligent identification technology and has better data privacy.
