Abstract
A driver attentiveness detection device and method using at least one digital camera device (2) and a control unit (5). The camera device (2) is arranged to detect eye configurations of a vehicle driver (4). The control unit (5) compares the detected eye configurations with previously stored models of eye configuration samples (13, 14, 15, 16) which are indicative of eyes that look inside or outside a predetermined field of view (6). The control unit (5) further determines whether the detected eye configurations are looking inside or outside the predetermined field of view from the comparison, and is also arranged to indicate when the vehicle driver (4) has been determined to be looking outside the predetermined field of view (6) to a predetermined extent.
