MOVEMENT INFORMATION CALCULATION METHOD, MOVEMENT INFORMATION CALCULATION DEVICE, AND MOVEMENT INFORMATION CALCULATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce a calculation load of movement information.SOLUTION: A computer converts plural acceleration vectors respectively indicating acceleration of a moving body in plural times in a predetermined period detected by a first coordinate system by an acceleration sensor into plural acceleration vectors in a second coordinate system (step 201). Then the computer converts the plural acceleration vectors in the second coordinate system into a series of numbers in a frequency area expression (step 202). Then the computer determines a movement distance and a movement direction of the moving body based on a coefficient of a predetermined degree of member on the series of numbers (step S203), and then outputs the movement information indicating the movement distance and movement direction (step 204).SELECTED DRAWING: Figure 2
