PURPOSE:To intuitively recognize the transition of a moving body such as the speed and moving time lapse in the running path by determining the position in a fixed unit time by interpolation based on the positional information of the moving body, and distinguishably displaying each position. CONSTITUTION:The CPU 22 of a controller 20 stores finite coordinate value data (e.g., 2 or 3) obtained from a navigational device 13 at uneven time intervals in a RAM 24. The CPU 22 reads out the data stored in the RAM 24 and determines the positions (coordinate value data) in every fixed time interval (1 sec) based on the read-out data by interpolation. The running speed, running distance and running time of a moving body on the running path can be recognized. |
