Swing analyzing device, swing analyzing system, and swing analyzing method

Abstract

A swing analyzing device (a sensor unit) includes an exercise-information acquiring section configured to acquire an output of an inertial sensor (an acceleration sensor and an angular velocity sensor), an information acquiring section (a movement-information acquiring section) configured to acquire at least either one of position information and movement information, and a control section (a sampling-rate control section) configured to control a storage sampling rate of the storage of the output of the inertial sensor. The control section changes the storage sampling rate according to at least either one of the position information and the movement information.

What is claimed is: 
     
         1 . A swing analyzing device comprising:
 an exercise-information acquiring section configured to acquire an output of an inertial sensor;   an information acquiring section configured to acquire at least either one of position information and movement information;   a storing section configured to store the output of the inertial sensor; and   a processor functioning as a control section configured to control a storage sampling rate of the storage by the storing section, wherein   the control section changes the storage sampling rate according to at least either one of the position information and the movement information.   
     
     
         2 . The swing analyzing device according to  claim 1 , wherein the control section changes the storage sampling rate by changing a measurement sampling rate of measurement by the inertial sensor according to at least either one of the position information and the movement information. 
     
     
         3 . The swing analyzing device according to  claim 1 , wherein the control section sets, on the basis of at least either one of the position information and the movement information, the storage sampling rate lower in a state in which a moving state is detected than in a state in which the moving state is not detected. 
     
     
         4 . The swing analyzing device according to  claim 1 , wherein the position information or the movement information is calculated by a navigation satellite system. 
     
     
         5 . The swing analyzing device according to  claim 1 , wherein the position information or the movement information is calculated according to an output of a motion sensor including the inertial sensor. 
     
     
         6 . A swing analyzing system comprising:
 an exercise measuring device including an inertial sensor; and   an exercise analyzing device including:
 an information acquiring section configured to acquire at least either one of position information and movement information; 
 a storing section configured to store an output of the inertial sensor; and 
 a processor functioning as a control section configured to control a storage sampling rate of storage by the storing section, wherein 
   the control section changes the storage sampling rate according to at least either one of the position information and the movement information.   
     
     
         7 . A swing analyzing method comprising:
 acquiring an output of an inertial sensor;   acquiring at least either one of position information and movement information;   determining on the basis of at least either one of the position information and the movement information whether a user is moving;   changing, on the basis of a result of the determination concerning whether the user is moving, a storage sampling rate of storage of the output of the inertial sensor by a storing section; and   the storing section storing the output of the inertial sensor at the changed storage sampling rate.
