PROBLEM TO BE SOLVED: To provide an information processing device capable of computing an optimum trajectory of motion using an inertial sensor according to a user's movement time.SOLUTION: An information processing device 1 includes: an acceleration sensor 12 for detecting an acceleration; an angular velocity sensor 13 for detecting an angular velocity; and an MCU 19. The information processing device has a program area 17 in which the first arithmetic processing by a shooting method which is suitable to reciprocating motion, the second arithmetic processing by a shooting method which is suitable to one-way motion, and the third arithmetic processing by a feedback integration method are stored. The MCU 19 includes a selection unit 24 which selects the first arithmetic processing when the movement time in a movement section is not beyond a first elapsed time, selects the second arithmetic processing when the time is beyond the first elapsed time and below a second elapsed time, and selects the third arithmetic processing when the time is the second elapsed time or more. The MCU 19 includes a control unit 25 which calculates, based on the acceleration and angular velocity, the trajectory of motion in the movement section by use of the selected arithmetic processing. |
