This project proposes to provide a real-time identification of potentially intoxicated drivers who are attempting to break the law and endanger others. With the use of AI and facial recognition combined with sensor data, Sober Guardian is able to detect if the driver is impaired during any time with high accuracy. This detection will then provide a prompt notification to the driver and other related parties - such as friends, family, and law enforcement - and prevent them from driving in order to reduce the risk of serious health emergencies such as car accidents. With Sober Guardian’s high accuracy, we are able to not only reduce the number of field tests being conducted, freeing up officers, but also reduce the amount of drunk drivers on the road. With the help and use of Sober Guardian, it is expected that the project can make an impact by resulting in less accidents and people driving under the influence, which can help save many lives.
