AlcoWatch Intoxication Detection
PúblicoContenido Descargable
open in viewerThe goal of this MQP was to use the gyroscope and accelerometer in a smartwatch to classify a user’s BAC. We gather gyroscope and accelerometer data of 33 participants from a smartwatch while they walk at various levels of intoxication. We compute time and frequency domain features from both sensors, as well as features derived from segmenting arm movement into forward/backward swing motion. These features are then classified using various supervised machine learning methods. Random Forest was the most accurate classifier at 79.68% for a binary classification system of the [0.00 - 0.08) or [0.08+) BAC ranges. A smartwatch app is built using this model that estimates user BAC into these two bins from their gait in real time.
