Digital interventions are promising means to promote behavioral change and thus prevent alcohol-related harm, especially in critical moments such as driving. This requires real-time information on a person’s blood alcohol concentration (BAC) . Here, we develop an in-vehicle machine learning system to predict critical BAC levels. Our system leverages driver monitoring cameras mandated in numerous countries worldwide. We evaluate our system with 􀀽 = 30 participants in an interventional simulator study. Our system reliably detects driving under any alcohol influence (area under the receiver operating characteristic curve [AUROC] 0. 88) and driving above the WHO recommended limit of 0. 05 g/dL BAC (AUROC 0. 79) . Model inspection reveals reliance on pathophysiological effects associated with alcohol consumption. To our knowledge, weare the first to rigorously evaluate the use of driver monitoring cameras for detecting drunk driving. Our results highlight the potential of driver monitoring cameras and enable next-generation drunk driver interaction preventing alcohol-related harm.  \nCCS CONCEPTS  \n• Human-centered computing → Empirical studies in HCI; Ubiquitous and mobile computing systems and tools; • Applied computing → Consumer health.  \nKEYWORDS  \nhealth; safety; driving; alcohol; eye movements; head movements; driver monitoring  \n∗Joint first author.  \n†Joint last author.‡Corresponding author.  \nFelix Wortmann†‡ [felix.wortmann@unisg.ch](felix.wortmann@unisg.ch)[ ](felix.wortmann@unisg.ch)[University of St. Gallen](University of St. Gallen)  \nSt. Gallen, Switzerland  \n1 INTRODUCTION  \nAlcohol consumption is responsible for 5% of the global disease burden and is further the cause of 1 in 20 deaths worldwide [110] . To promote behavior change, digital interventions provide effective means to prevent harm in critical situations due to alcohol consumption and intoxication [3, 5, 64, 65] . In particular, digital interventions could promote behavior change by delivering real-time targeted feedback on alcohol consumption. However, to intervene early, real-time predictions of alcohol consumption are needed.  \nAlcohol consumption increases, among others, the risk of traffic crashes, making drunk driving one of the leading causes of severe crashes on public roads. For example, in the US, around 30 people die each day in traffic crashes in which one of the parties is under the influence of alcohol, and, together, alcohol-related crashes amount to 30% of all traffic fatalities [67]. To prevent alcohol-related crashes, in-vehicle systems are needed to detect drunk driving and enable targeted interventions. Examples of such interventions are, e.g., warnings of impairment and forced stops ofthe vehicle.  \nAs of today, the only reliable measurement technology for identifying intoxicated driving are ignition interlock devices that analyze a driver’s breath alcohol.
