Detecting sobriety or driving condition using a mobile device

摘要

The invention relates to a sobriety check, in particular for determining the ability to drive, for a user of a mobile device, e.g. a mobile phone. The user data is analyzed to determine whether a user may be in an impaired condition or demonstrating impairment related activity. The user data reflects the location of the user or the behavior of the user. In response to the impairment related activity, a contact database is accessed for one or more other users. A communication session is initiated with the one or more other users. A poll of the one or more uses results in a sobriety assessment or a driving condition assessment of the potentially impaired user.
