PROBLEM TO BE SOLVED: To reduce movement of a line of sight of a driver as far as possible when the driver confirms a position of a plurality of display elements displayed on a display device during travelling of the vehicle.SOLUTION: When a vehicle travels, a driver can very quickly perceive a position of a part (object) which exists on an optical flow OF. A display device 11 on which a plurality of display elements to be selection objects by the driver are displayed is positioned and set so that the optical flow OF of the driver during the travelling of the vehicle passes through the display device 11. During the travelling of the vehicle, a plurality of display elements A1-A8 are displayed so as to be diagonally aligned along the optical flow OF. For example, a standard front gazing point during travelling at a speed of 80 km/h is present at a position about 70 m ahead, and the optical flow extends in a direction of a self vehicle at an angle of about 55 degrees with respect to a horizontal line passing through the front gazing point. |
