Can Your Smartphone Tell When You're Drunk?!

Your smartphone might know when you have had a few too many adult beverages...

But how?!

It turns out the device can measure changes in how you walk!

Researchers at the University of Pittsburgh did a study using people who had been drinking and a smart phone's accelerometer. During walking tests, the researchers used the phone's data to determine differences in gait when someone's blood-alcohol level was over .08 percent... And the results were 90 percent accurate!

"This controlled lab study shows that our phones can be useful to identify 'signatures' of functional impairments related to alcohol," researcher and emergency physician Brian Suffoletto said in a statement.

The phone's sensors could potentially help alert sponsors of people seeking treatment for alcohol addiction, prevent drunk driving, or simply let people know when they have had enough to drink.

"I lost a close friend to a drinking and driving crash in college," Suffoletto added. "And as an emergency physician, I have taken care of scores of adults with injuries related to acute alcohol intoxication. Because of this, I have dedicated the past 10 years to testing digital interventions to prevent deaths and injury related to excessive alcohol consumption."

Researchers say even more studies on the technology are coming.
