A comparison of the BreathalEyes system with other methods of alcohol content detection
The BreathalEyes app for iPhone uses the smartphone's camera to detect and measure involuntary eye movement, and then offers an approximate blood alcohol content reading

Common sense should be enough to tell us that getting behind the wheel of a car after consuming alcohol is not a particularly good idea, but still there are those who stupidly risk life and liberty by driving home after the party. When trying to convince such people to call a taxi, friends are often faced with a call for proof that the would-be driver is unfit to drive. Instead of analyzing a user's breath to determine alcohol content, the BreathalEyes app for iPhone detects involuntary eye movement in a similar way to field sobriety tests undertaken by police patrols.
