Panasonic develops drowsiness-control technology
Panasonic Corp. announced that it has developed a drowsiness-control technology for detecting and predicting a person's level of drowsiness prior to driving. The technology, which is designed to help prevent drowsy driving, detects a driver's shallow drowsiness at the initial state by accurately measuring the driver's states without physical contact, including blinking features and facial expressions. (Shallow drowsiness is assessed as Level 2, slightly drowsy, based on the equally spaced five levels of drowsiness.) The system captures the driver’s states using an in-vehicle camera and processes the signals via artificial intelligence. Using measurement data from the in-vehicle environment, such as heat loss from the driver and illuminance, the technology reportedly predicts transitions in the driver's drowsiness level. Panasonic says that the technology also combines a thermal sensation monitoring function, which employs an infrared array sensor with 64 pixels and a super-resolution algorithm that offers clear thermal images and allows the driver to stay comfortably awake while driving.
In the development process, the company compiled a database of various measurements on drowsiness and biological signals, and it analyzed, from a physiological standpoint, the relationship between approximately 1800 parameters related to features such as blinking and facial expressions, and drowsiness, that were extracted from the database. Based on the results of an analysis of drowsy expressions compiled during joint research with the Ohara Memorial Institute for Science of Labour, a public interest foundation, Panasonic developed an artificial intelligence capable of estimating an individual's drowsiness level.
This patented technology is suitable for drowsiness prediction and control applications in human- and environment-monitoring systems in such places as private and commercial vehicles, offices, and educational institutions. Samples will be available from October 2017. Additional technology specs and details are available upon request. Learn more at www.PanasonicMovesUs.com.
