Presented at First international conference on driver distraction and inattention (DDI 2009), Gothenburg, Sweden, September 28-29, 2009

Lane-departure warning and lane-keeping assistance systems may be more acceptable to users if the assistance was adaptive to the driver’s state. Techniques to detect the driver as being distracted while driving are discussed. Eye- and head-tracking devices seem to be most promising today. Nonetheless, other methods such as detection of the use of in-vehicle information systems or tracking of drivers’ activities have potential. While adaptations of lane departure warning systems to the driver’s state were not found to increase user acceptance, the use of an adaptive lane-keeping assistance system yielded higher acceptance as well as superior lane-keeping performance.
