New Car Anti-Theft Device Profiles Your Rear End 126
Hugh Pickens writes "A car-seat identifier developed at Japan's Advanced Institute of Industrial Technology by Associate Professor Shigeomi Koshimizu can recognize a person by his or her rear end with 98 percent accuracy when the person takes a seat in his car. The bucket seat's lower section is lined with 360 pressure sensors that measure pressure on a scale from 0 to 256, sending information to a laptop, which aggregates the information, generates the key data and produces a precise map of the seated person's rear profile. Researchers say traditional biometric techniques such as iris scanners and fingerprint readers cause stress to people undergoing identity checks, while the simple act of getting seated carries less psychological baggage. Koshimizu wants to see his work available commercially as an anti-theft product in two to three years if automakers agree to collaborate. He sees possibilities of this device being used beyond auto-theft identity protection to a device for security identification in office settings, where users log on to their PCs as they sit down."
Re:Detect differences between full and empty load? (Score:5, Informative)
Some people apply their rear pressure differently based on if their rear load is full, empty or something in between. Not only does your overall weight change, but also the formation of rear pressing against the seat will be different, especially depending on your nutrition and different days. Is it going to be able to detect such load changes without many problems? Obviously there needs to be some kind of threshold, but if your rear pressure varies a lot the device could even lock you out from using your car.
There is a traditional keypad override for instances in which your rear is not recognized: keys in pocket, wallet, new jeans, need to shit, etc.
