Alcohol abuse has been a pervasive problem worldwide, causing 88,000 annual deaths. Recently, several projects have attempted to estimate a users level of intoxication by measuring gait using mobile sensors. The goal of this project was to compare a deep learning approach to previous methods to predict the blood alcohol concentration of a user by training a convolutional neural network and creating a mobile app which could accurately determine intoxication level. We gathered data from 38 participants over the course of 12 weeks, collecting accelerometer and gyroscope data simultaneously from both a smartwatch and smartphone. Our neural networks accuracy is roughly 64% on the test set and 69% on the training set into 5 BAC ranges for an input containing two seconds of data.
