Abstract

A control device includes a timing control unit that controls a timing, at which a mark projector for projecting a mark stops the projection of the mark, based on an output of an inertial sensor mounted on exercise equipment or a user.

1 . A control device, comprising:
 a timing control unit that controls a timing, at which a mark projector for projecting a mark stops or starts projection of the mark, based on an output of an inertial sensor mounted on exercise equipment or a user.   
     
     
         2 . The control device according to  claim 1 ,
 wherein the timing control unit stops the projection at a timing before the inertial sensor starts measurement of a swing after start of the projection.   
     
     
         3 . The control device according to  claim 2 ,
 wherein the timing is a timing at which a stationary state of the exercise equipment over a predetermined period is detected.   
     
     
         4 . The control device according to  claim 1 ,
 wherein the timing control unit starts the projection at a timing, at which the user performs a predetermined gesture with the exercise equipment, after start of the inertial sensor.   
     
     
         5 . The control device according to  claim 1 ,
 wherein the timing control unit starts the projection at a timing, at which a hitting portion of the exercise equipment faces a ground side, after start of the inertial sensor.   
     
     
         6 . The control device according to  claim 1 ,
 wherein an optical axis direction of the mark projector is a detection axis direction of the inertial sensor.   
     
     
         7 - 14 . (canceled) 
     
     
         15 . A control method, comprising:
 controlling a timing, at which a mark projector for projecting a mark stops or starts projection of the mark, based on an output of an inertial sensor mounted on exercise equipment or a user.   
     
     
         16 . The control method according to  claim 15 ,
 wherein, in the controlling, the projection is stopped at a timing before the inertial sensor starts measurement of a swing after start of the projection.   
     
     
         17 . The control method according to  claim 16 ,
 wherein the timing is a timing at which a stationary state of the exercise equipment over a predetermined period is detected.   
     
     
         18 . The control method according to  claim 15 ,
 wherein, in the controlling, the projection is started at a timing, at which the user performs a predetermined gesture with the exercise equipment, after start of the inertial sensor.   
     
     
         19 . The control method according to  claim 1 ,
 wherein, in the controlling, the projection is started at a timing, at which a hitting portion of the exercise equipment faces a ground side, after start of the inertial sensor.   
     
     
         20 . A recording medium on which a control program is recorded,
 wherein the control program causes a computer to control a timing, at which a mark projector for projecting a mark stops or starts projection of the mark, based on an output of an inertial sensor mounted on exercise equipment or a user.
