Abstract

An electronic apparatus includes a determination section that performs a determination of a standing still state of exercise equipment on the basis of a preset determination criterion by using an output from an inertial sensor, and a notification section that notifies a user of information indicating a state change of the exercise equipment until reaching the determination.

What is claimed is: 
     
         1 . An electronic apparatus comprising:
 a determination section that performs a determination of a standing still state of an exercise equipment by using an output from an inertial sensor; and   a notification section that notifies a user of information indicating an attitude change of the exercise equipment until reaching the determination.   
     
     
         2 . The electronic apparatus according to  claim 1 ,
 wherein the notification section notifies the user of permission of starting of a swing of the exercise equipment in a case where the exercise equipment is maintained in a predetermined state for a predetermined period of time.   
     
     
         3 . The electronic apparatus according to  claim 1 ,
 wherein the exercise equipment is a golf club, and   wherein the notification section notifies the user of an attitude change of the golf club in a direction intersecting a ground plane as the information.   
     
     
         4 . The electronic apparatus according to  claim 1 ,
 wherein the exercise equipment is a golf club, and   wherein the notification section notifies the user of an attitude change of the golf club in a horizontal direction with respect to a ground plane as the information.   
     
     
         5 . The electronic apparatus according to  claim 1 ,
 wherein the exercise equipment is a golf club, and   wherein a criterion of the determination is set on the basis of a lie angle of the golf club.   
     
     
         6 . The electronic apparatus according to  claim 1 ,
 wherein the notification section notifies the user of the criterion of the determination along with the information.   
     
     
         7 . The electronic apparatus according to  claim 1 ,
 wherein the notification section performs the notification by using at least one of an image, light, sound, vibration, an image change pattern, a light change pattern, a sound change pattern, and a vibration change pattern.   
     
     
         8 . The electronic apparatus according to  claim 1 ,
 wherein the inertial sensor includes at least one of an acceleration sensor and an angular velocity sensor.   
     
     
         9 . A system comprising:
 the electronic apparatus according to  claim 1 ; and   the inertial sensor.   
     
     
         10 . A system comprising:
 the electronic apparatus according to  claim 1 ; and   a head mounted display that displays the information.   
     
     
         11 . A system comprising:
 the electronic apparatus according to  claim 1 ; and   an arm mounted display that displays the information.   
     
     
         12 . A determination method comprising:
 performing a determination of a standing still state of an exercise equipment by using an output from an inertial sensor; and   notifying a user of information indicating an attitude change of the exercise equipment until reaching the determination.   
     
     
         13 . The determination method according to  claim 12 ,
 wherein, in the notifying of the information, the user is notified of permission of starting of a swing of the exercise equipment in a case where the exercise equipment is maintained in a predetermined state for a predetermined period of time.   
     
     
         14 . The determination method according to  claim 12 ,
 wherein the exercise equipment is a golf club, and wherein, in the notifying of the information, the user is notified of an attitude change of the golf club in a direction intersecting a ground plane as the information.   
     
     
         15 . The determination method according to  claim 12 ,
 wherein the exercise equipment is a golf club, and   wherein, in the notifying of the information, the user is notified of an attitude change of the golf club in a horizontal direction with respect to a ground plane as the information.   
     
     
         16 . The determination method according to  claim 12 ,
 wherein the exercise equipment is a golf club, and   wherein a criterion of the determination is set on the basis of a lie angle specific to the golf club.   
     
     
         17 . The determination method according to  claim 12 ,
 wherein, in the notifying of the information, the user is notified of the criterion of the determination along with the information.   
     
     
         18 . The determination method according to  claim 12 ,
 wherein, in the notifying of the information, the notification is performed by using at least one of an image, light, sound, vibration, an image change pattern, a light change pattern, a sound change pattern, and a vibration change pattern.   
     
     
         19 . The determination method according to  claim 12 ,
 wherein the inertial sensor includes at least one of an acceleration sensor and an angular velocity sensor.   
     
     
         20 . A recording medium recording a determination program causing a computer to execute:
 performing a determination of a state of an exercise equipment by using an output from an inertial sensor; and   notifying a user of information indicating an attitude change of the exercise equipment until reaching the determination.
