ANALYSES OF DRIVER'S BODY MOVEMENT FOR DETECTION OF HYPOVIGILANCE DUE TO NON-DRIVING COGNITIVE TASK

Abstract This paper investigates how driver's body movement may be affected by a non-driving and possibly distractive cognitive task. We have collected data on body movement under several settings, such as cases in which cognitive tasks are given intermittently, or cases in which cognitive tasks are given for a relatively long time period. A driver-adaptable method is proposed for detection of increase in tension via body movement. The method is evaluated with experimental data.
