車載GUIの操作に関する知識がその操作と自動車運転に与える影響

抄録

This study aimed to clarify the effect of the knowledge of in-vehicle GUI operation to the performance of the in-vehicle GUI operation and the automobile driving by the comparison among the experiment conditions. An experiment was conducted using a driving simulator, in which the primary task was a tracking task and the secondary task was a GUI operation. The experimental factors were the presence or absence of the knowledge of the GUI (between) and the number of the minimum steps of the GUI operation (within). The tracking error degree, the car distance between the leading car, the yaw angle of the neck movement, the secondary task completion time, and the ratio of the GUI operation mistake were measured. The results showed that the knowledge affects less tracking error and the better GUI operation performance. It suggests the knowledge contributes to enhance driving and in-vehicle GUI operation.
