Design and Implementation of a Drunk Driving Detection System

"Participants will drive in three different states (sober, drunk above and below the legal limit) on designated circuits using a driving simulator. After the initial sober driving session, participants are administered pre-mixed alcoholic beverages (e.g., vodka orange). Participants are expected to achieve a target BrAC of 0.35 mg/l (legal limit in Switzerland is 0.25 mg/l BrAC) before the second driving session starts. Finally, the third driving session starts when the participants' BrAC drops to 0.15 mg/l. Heart rate, skin conductance, accelerometer, eye movement, radar, facial expression, and speech will be recorded by a smart-watch, an eye-tracker, microphones and an onboard camera, respectively.~Participants will be blinded to their alcohol levels during the study. They will have to rate their symptoms and their performance via questionnaires before and after each driving session. Further, capillary blood and oral fluid samples will be collected."
