Simultaneous Measurement of a Driver's Gaze Movement and Head Motion, and a Proposal of the Evaluation Indexes of Gaze Movement

Abstract

To assist drivers to drive safely, it is essential to detect driver's states. Among the driver's states, it is important to detect the degradation of attention because many traffic accidents were caused by human error.In this paper, a method for measuring gaze movement and head motion of a driver simultaneously has been developed using Eye Mark Recorder. The real gaze direction and head position of a driver were obtained as numerical values. The use of a cellular phone call was adopted as a task during driving to compare normal driving (no task). It became clear from these experiments that in the case of the use of cellular phone call during driving, the degradation of concentration for driving was detected, and head motion became large to confirm safe driving hurriedly. Also the evaluation indexes of gaze movement were proposed from these experimental results.
