Over seven hours, the themes had their breath alcohol focus analyzed they usually additionally carried out a strolling job whereas carrying a smartphone on their decrease again.

By measuring and analyzing acceleration, aspect to aspect, up and down, and ahead and backward actions whereas strolling, researchers had been ready to precisely predict whether or not a participant’s breath alcohol focus was at or above a zero.08 % (the authorized restrict for driving in the US) with 90 % accuracy.
