Sobriety tests might become a little more advanced in the near future. Computer scientists, Georgia Koukiou and Vassilis Anastassopoulos, of Greece have come up with two new algorithms that may be able to tell if you have been drinking through the use of infrared-camera technology.
In a paper, published in the International Journal of Electronic Security and Digital Forensics, the two scientist used two different test with thermal imaging devices. One was used to monitor the bodies overall heat since alcohol increases blood-vessel dialation. The second method was to measure the thermal images of the face, since the nose of a someone who has been drinking will be warmer, while their forehead will be relatively cool.
Though there are still other variables that might interfere with the test, it is believed this technology can be used by police forces and club owners to help spot those who are drunk a little easier.
