Abstract
A relative motion sensor mounted in the headrest of a vehicle driver seat is used to assess the head pose of a vehicle driver and adjust the headrest position to optimize both the safety of the driver and the sensitivity of the relative motion sensor. At the beginning of each ignition cycle, the relative motion sensor is used to adjust the position of the headrest relative to the driver's head for optimal driver safety, and the relative motion sensor is oriented to provide optimal sensitivity for head pose assessment when the headrest is positioned for driver safety.
