Movement capability evaluation device, movement capability evaluation system, movement capability evaluation program and movement capability evaluation method
A movement ability evaluating apparatus configured to evaluate movement ability of a subject, comprising: a communication unit configured to acquire front-back acceleration right-left acceleration, and up-down acceleration during movement of the subject measured by an acceleration sensor 1 attached to waist of the subject M. There is also a control unit configured to evaluate the movement ability, based on temporal change of the front-back acceleration, the right-left acceleration, and the up-down acceleration acquired by the communication unit, wherein the movement ability includes at least one of front-back balance, weight shift, and right-left balance during movement of the subject. The control unit executes at least one of the following corresponding to the movement ability: (a) calculation of an indicator indicating the front-back balance, based on an autocorrelation function of the front-back acceleration;(b) calculation of an indicator indicating the weight shift, based on an autocorrelation function of the up-down acceleration; and (c) calculation of an indicator indicating the right-left balance, based on an autocorrelation function of the right-left acceleration and an autocorrelation function of the front-back acceleration. Other aspects relate to a movement ability evaluating system, computer program and method respectively.
