New research on cell phones can tell if a user is drunk by the change in their walk

A study released Tuesday in the Journal of Studies on Alcohol and Drugs says cell phones can detect changes in a user's walk to determine whether someone is drunk, and Brian Suffoletto, lead researcher in the Department of Emergency Medicine at Stanford University School of Medicine, said he hopes the study will help solve the problem of drunk driving, Vinepair reported.

The study monitored 22 adults between the ages of 21 and 43. Researchers gave each participant a vodka cocktail with enough alcohol concentration to reach 0.2 percent and a smartphone strapped to their waist.

They then performed a walking test every hour for seven hours, and the phone was able to measure the speed and movement of each step. In about 90 percent of cases, the researchers were able to use the change in gait to identify situations where the participant"s breath alcohol concentration exceeded 0.08 percent (the legal limit for driving).
