Here is an interesting development. Apparently butt prints left on car seats are like finger prints. The University of Tokyo has already developed a prototype smart car seat capable of detecting when its occupant is on the verge of falling asleep. The seat features respiration-monitoring sensors and pressure sensors that monitor the pulse. The system can identify the physiological changes that occur 10 minutes before a driver actually falls asleep.
A new company is hoping to use pressure sensors built into car seats to help detect when a car is being driven by an unauthorized person. The seats will use 360 sensors to measure a person’s bum in order to confirm their identity.The system tested was able to identify drivers with 98% accuracy during experiment. The company will with car companies to commercialize it as an anti-theft system. It will be interesting to see how it measures the same person who adds or loses some weight.
