A new method is proposed to measure the useful field of view (UFOV) when one can recognize the objects by visual task. Since the distance from fixation point to target mark is the strength of stimuli, the psychometric curve is utilized for UFOV by the statistical estimation by Probit and Staircase methods. An approximation by ellipse is also applied to represent the contour of the UFOV. The proposed method enables one to estimate the threshold of recognition with probability that means the UFOV with the detection probability. Therefore, it is proposed in this paper to determine the threshold in any direction from fixation point of the UFOV with visual task by psychometric curve. The availabilities of the proposed method are examined for accuracy and efficiency by the experiments.

本研究では、まず自動車運転時に運転状況に応じて眼球運動が変化しているかどうかを確認し、自動車運転時の眼球運動特性を明らかにする。そして、眼球運動と視野画像の関連性を分析することで、眼球運動を誘発する条件や環境を明らかにする。視野画像全体を特徴づける指標として、視野画像のフレーム間の各画素のRGB値の差の総和を取り上げ、眼球運動特性との関係性を考察する。

In order to keep a highly safe and reliable system of car driving, it is important that the system would be considered as a man-machine system including not only the feature of vehicle movement but also human perception, cognition, and motion of a driver. In this paper, it is examined to clarify the relation between feature of eye movements and driving behavior in conventional and unconventional situation by the experiments using the driving simulator and the eye tracking system. The measurements of time histories of eye movements were performed in the situation of different traffic regulation by the simulator. It is recognized in both turns that typical patterns of eye movements in horizontal axis appeared between the start and end of the turns. It is found from the time histories of eye movements by synchronizing that of vehicle data that the appearances of fixations were distributed uniformly on the trajectories of vehicle by trained drivers from the start of turning to the end, while the appearance of fixation by untrained drivers are concentrated in the beginning of turning or the end. These facts mean that the untrained driver did not receive visual information during the operation of turning, therefore the trajectories of vehicle by untrained driver showed the overshooting in the right turn and undershooting in the left turn.
