A mobile support system to assist DUI offenders on probation in reducing DUI relapse

This paper proposes a mobile support system to assist DUI (Driving Under the Influence of Alcohol) offenders on probation in avoiding committing DUI again. A customizable portable breathalyzer is used in conjunction with the DUI offender's mobile phone to self-administer alcohol screening tests and send the results to a server. The system also transmits contextual information and momentary feedback to the server. Records pertaining to alcohol use are summarized on a server and a list of triggering events are inferred from the information sent from the phone. This data can then be used to characterize the difficulties faced by these individuals, monitor their compliance with their probation requirements, and gauge their progress.
