EXERCISE SUPPORT DEVICE, EXERCISE SUPPORT METHOD, AND EXERCISE SUPPORT PROGRAM

摘要

In an exercise support device of the present invention, acceleration signals in three axis directions including vertical, longitudinal, and lateral directions corresponding to the motion of a user performing exercise of cyclically moving feet are obtained, and a first maximum value in one cycle of a foot movement in the vertical acceleration signal is obtained. Subsequently, a search is made for first and second change points related to foot landing and takeoff motions in a composite acceleration signal obtained by combining acceleration signals in at least two axis directions, in forward and backward directions of the time point of a second maximum value of the composite acceleration signal, within the cycle. Then, a time period between the first and second change points is obtained as a change point interval, and a foot landing period while exercising is calculated based on the first maximum value and the change point interval.

1. An exercise support device comprising:
an acceleration measuring section which obtains acceleration signals in three axis directions including a vertical direction, a longitudinal direction, and a lateral direction corresponding to a motion of a body of a user performing exercise of cyclically moving feet; a vertical acceleration maximum value obtaining section which obtains a first maximum value within a period of one cycle of a foot movement of the user in an acceleration signal in the vertical direction obtained by the acceleration measuring section; a signal processing section which searches for a first change point related to foot landing and takeoff motions of the user in a composite acceleration signal obtained by combining acceleration signals in at least two of the three axis directions, in a forward direction of a time point of a second maximum value of the composite acceleration signal, and searches for a second change point related to foot landing and takeoff motions of the user in the composite acceleration signal, in a backward direction of the time point of the second maximum value, within the period of one cycle; and a landing period calculating section which obtains a period of time between the first change point and the second change point as a change point interval, when the first change point and the second change point are detected by search in the signal processing section, and calculates a foot landing period of the user while exercising based on the first maximum value of the acceleration signal in the vertical direction and the change point interval.
