Smartphones have taught to determine the user’s intoxication by his gait

Researchers from Stanford University conducted an experiment and were able to prove that the capabilities of a smartphone can determine the degree of intoxication of a user by his gait. This will help avoid drunk driving in the future.

A smartphone can detect when a user has drunk too much alcohol by detecting changes in their gait, according to a new study published in the Journal of Studies on Alcohol and Drugs.

For the study, the researchers measured the gait of 22 adults aged 21 to 43 years. They received an alcoholic beverage that they had to drink for seven hours. All this time, at regular intervals, they had to walk ten steps back and forth with the phone in their pocket.

The devices measured acceleration and mediolateral (side-to-side), vertical (up and down), and anteroposterior movements while walking. These data can be analyzed and concluded about the degree of alcohol intoxication of the user.

“Each of us already has powerful sensors in our pockets that we carry with us wherever we go,” the researchers noted. “We need to learn how to use them to serve public health.”

Having real-time information about alcohol intoxication can be important in helping people reduce their alcohol consumption or prevent drinking before driving. In the future, they plan to create a separate application that can be integrated with programs for smart devices.
