One of the more bizarre smartphone applications I’ve found- an app that simulates the Horizontal Gaze Nystagmus (HGN) test (the follow my pen with your eyes test).
Friends create iPhone app to estimate blood alcohol
A drunken driving test may not seem the likeliest place to come up with a mobile phone app, but that’s when inspiration struck Nashville resident Clay Bradley.
He told The Nashville Ledger that he was following a policeman’s pen with his eyes when he thought a smartphone could be used for the same purpose.
He mentioned his idea to a couple of friends, and they came up with BreathalEyes.
The 99-cent app launched in November and can be used to measure involuntary eye movements when people are intoxicated, which is one method police use in field sobriety tests.
It’s only a matter of time before the police catch on and add it to their arsenal of unscientific DUI testing methods.
