Abstract: Regarding acceleration on each of three axes Gx, Gy, and Gz calculated by a microcomputer, acceleration on one of the three axes is acceleration in a vertical direction perpendicular to the ground, and acceleration on each of the other two axes is acceleration in a direction parallel to the ground, the other two axes being perpendicular to each other. A type of action of the human body in a predetermined period is determined by comparing a predetermined threshold value with the acceleration in the vertical direction in the predetermined period.
