"Alcohol distinctly affects movement, gait and balance in ways that can be detected by the built-in motion sensors on devices people carry around with them all the time," said Ben Nassi, a post-graduate student from the university’s Department of Software and Information Systems Engineering and the device’s developer. "Our system simply takes a baseline reading while walking from the car to the bar and another one on the way back to compare and identify movements that indicate drunkenness."

"We formalize the problem of drunkenness detection as a supervised machine learning task, both as a binary classification problem (drunk or sober) and a regression problem (the breath alcohol content level)."
