In addition, a sensor value storage unit 71 is set in an area of the removable medium 31.
The sensor value storage unit 71 stores the sensor value acquired from the sensor unit 12 and the sensor value after axis correction.

  The sensor value acquisition unit 51 acquires the angular velocity and the acceleration from the sensor unit 12. The acquired sensor values of the angular velocity and the acceleration are stored in the sensor value storage unit 71.

The axis correction unit 52 performs axis correction on the acquired sensor values of the angular velocity and the acceleration.
In the present embodiment, since the sensor unit 12 is mounted on the waist of the person to be measured, it is possible to lean forward with respect to the vertical axis when walking or traveling upright, and when traveling on a bicycle where steering operation is performed. Because of this, the upper and lower axes of the sensor values are also shifted so as to tilt forward with respect to the vertical axis.
For this reason, in the present embodiment, the axis correction unit 52 performs axis correction in which the vertical direction of the sensor value shifted in the forward inclined state is aligned with the gravity direction (vertical direction).
Specifically, the axis correction unit 52 averages, for example, acceleration components of the respective axes for several cycles of the period of the running operation in which the regularity of the change in value is observed. The gravity direction is identified from the gravity component remaining by the averaging.
The axis correction unit 52 performs axis correction by rotating each axis of the acceleration and each velocity so that the specified gravity direction coincides with the vertical acceleration. Thereafter, the acceleration and angular velocity which have been subjected to the axis correction are stored in the sensor value storage unit 71.

The motion state determination unit 53 determines the motion state based on the acquired axis-corrected acceleration (gravity acceleration).
Specifically, when the maximum value of the obtained gravitational acceleration falls within the range of gravitational acceleration during traveling of the bicycle, the motion state determination unit 53 is in a state of riding on the bicycle (hereinafter referred to as “bicycle traveling”. If the maximum value of gravitational acceleration falls within the range of gravitational acceleration during walking, it is determined to be in a walking condition (hereinafter referred to as "walking condition") and gravity acceleration is If the maximum value falls within the range of gravitational acceleration during traveling, it is determined that the vehicle is traveling (hereinafter referred to as “traveling condition”).

In the present embodiment, the determination criterion is set based on the transition of the actual gravity acceleration in the motion state described below.
FIG. 4 is a diagram showing the transition of actual gravity acceleration in various motion states.
As shown in the example of FIG. 4, when the bicycle is actually traveled, the tendency of the gravity acceleration to transition is seen within the range where the maximum value of the gravity acceleration does not exceed 1.2 G.
Also, when actually walking, the tendency of the gravity acceleration to transition is seen in the range of the maximum value of the gravity acceleration of 1.2 G or more and 2 G or less.
In addition, during traveling, there is a tendency that the maximum value of the gravitational acceleration exceeds 2 G.
For this reason, in the present embodiment, the movement state is determined from the tendency of the transition of the gravitational acceleration in the movement state described above. That is, in the present embodiment, when the maximum value of the gravitational acceleration does not exceed 1.2 G, it is determined that the bicycle is in the traveling state, and the maximum value of the gravitational acceleration is in the range of 1.2 G or more and 2 G or less In this case, it is determined that the vehicle is in the walking state, and when the maximum value of the gravitational acceleration exceeds 2 G, the traveling state is determined.
