Car recognizes you, keeps you alert, from Discovery News.
Volvo has always been known for its stance on car safety. Whether that’s through headrests, airbags or seatbelts, or simply building cars tougher than the objects they’re likely to smash into, it’s given Volvo one of the safest reputations in the industry.
Modern safety thinking is a lot more high-tech, and concentrates as much on preventing accidents as surviving them. Ensuring the driver is alert is a big part of that, and Volvo’s latest technology allows the car to sense when the driver is tired or not paying attention. The system bathes the driver in infrared light, undetectable by the driver but enough for infrared sensors to pick up the driver’s position and eye movements.
