About AlcoGait & AlcoWear

Excessive alcohol use is the third leading lifestyle related cause of death in the United States. Smartphone sensing offers an opportunity to passively track alcohol usage and record associated drinking contexts. Drinkers can reflect on their drinking logs, detect patterns of abuse and self-correct or seek treatment.

AlcoGait: is a smartphone sensing app that passively detects a smartphone user's level of intoxication (how drunk) from their walk pattern (gait). AlcoGait extracts accelerometer features (time, frequency, statistical, wavelet and information theoretic domain) and gyroscope postural sway features (how much swaying) and classifies them using a Machine Learning approach.

AlcoWear: While gait sensor readings taken from a device attached to the user’s trunk (smartphone) are the most accurate, users often do not carry their phones (e.g. leave them on a table) while walking around during their day. Smartwatches are worn continuously but are less accurate due to noisier sensor readings (e.g. confounding hand gestures). AlcoWear extracts and classifies accelerometer and gyroscope features extracted from a smartwatch, and classifies them using a Machine Learning approach.
