Abstract
Driver distraction in a motor vehicle is assessed by capacitively detecting the driver's head pose relative to the forward direction of vehicle motion. A symmetrical array of sensor electrodes is disposed in the cockpit ceiling above the driver's head, and pairs of electrodes disposed along varying axes of rotation with respect to the forward direction are successively activated for capacitance measurement. The capacitance measurements are combined to form a signal whose strength depends on the degree of alignment between the driver's head (i.e., the head pose) and the respective axes of rotation, and the driver's head pose is calculated to assess driver distraction.
