Abstract

An motion supporting device includes a body-motion-information acquirer configured to acquire body motion information of an exercising player, a dynamic-information collector (a communicator) configured to collect dynamic information of an implement related to the exercise, and a timing determiner configured to determine, on the basis of the body motion information and the dynamic information, timing for informing the player of advice.

First claim

What is claimed is:

1 . An motion supporting device comprising:
a body-motion-information acquirer configured to acquire body motion information of an exercising player; a dynamic-information collector configured to collect dynamic information of an implement related to the exercise; and a timing determiner configured to determine, on the basis of the body motion information and the dynamic information, timing for informing the player of advice.

2 . The motion supporting device according to claim 1 , wherein
the body-motion-information acquirer includes a body motion sensor worn on a body of the player, and the body motion sensor measures the body motion information of the player.

3 . The motion supporting device according to claim 2 , wherein the body motion information includes at least one of acceleration information and angular velocity information generated according to a movement of the player.

4 . The motion supporting device according to claim 1 , wherein
the dynamic-information collector includes a sensor unit including at least one of an acceleration sensor, an angular velocity sensor, a ball sensor, and a positioning sensor attached to the implement, and the sensor unit collects the dynamic information.

5 . The motion supporting device according to claim 1 , wherein the timing determiner calculates a play motion indicator serving as an indicator of a play motion of the player on the basis of the dynamic information and the body motion information and determines the timing on the basis of an increase/decrease tendency of the play motion indicator.

6 . The motion supporting device according to claim 5 , wherein the play motion indicator is calculated by adding the dynamic information and the body motion information having a positive correlation to the play motion of the player and by subtracting the dynamic information having a negative correlation to the play motion of the player.

7 . The motion supporting device according to claim 5 , wherein the timing determiner detects an inflection point, which is a point in time when the increase/decrease tendency of the play motion indicator changes from a decrease tendency to an increase tendency and, when the play motion indicator after elapse of a predetermined period from the inflection point is equal to or smaller than a predetermined motion amount, determines that it is the timing for informing the advice.

8 . The motion supporting device according to claim 6 , wherein the timing determiner detects an inflection point, which is a point in time when the increase/decrease tendency of the play motion indicator changes from a decrease tendency to an increase tendency and, when the play motion indicator after elapse of a predetermined period from the inflection point is equal to or smaller than a predetermined motion amount, determines that it is the timing for informing the advice.

9 . The motion supporting device according to claim 1 , further comprising:
an informer configured to inform the advice; and an advice output section configured to output the advice to the informer, wherein the advice output section selects a valid advice at the timing determined by the timing determiner out of generated pieces of advice and outputs the valid advice to the informer.

10 . An motion supporting method comprising:
acquiring body motion information of an exercising player; collecting dynamic information of an implement related to the exercise; determining, on the basis of the body motion information and the dynamic information, timing for informing the player of advice; and selecting a valid advice at the timing and informing the player of the effecting advice.

11 . A storage medium having stored therein a computer program for causing a computer to execute:
acquiring body motion information of an exercising player; collecting dynamic information of an implement related to the exercise; determining, on the basis of the body motion information and the dynamic information, timing for informing the player of advice; and selecting a valid advice at the timing and informing the player of the effecting advice.

12 . An motion supporting system comprising:
the motion supporting device according to claim 1 ; an informer configured to inform the advice; and an advice output section configured to select a valid advice at the timing out of generated pieces of advice and output the valid advice to the informer.

13 . An motion supporting system comprising:
the motion supporting device according to claim 2 ; an informer configured to inform the advice; and an advice output section configured to select a valid advice at the timing out of generated pieces of advice and output the valid advice to the informer.

14 . An motion supporting system comprising:
the motion supporting device according to claim 3 ; an informer configured to inform the advice; and an advice output section configured to select a valid advice at the timing out of generated pieces of advice and output the valid advice to the informer.

15 . The motion supporting system according to claim 12 , further comprising a detecting device configured to detect the dynamic information.

16 . The motion supporting system according to claim 12 , further comprising a terminal device mounted with the body-motion-information acquirer and the informer.

17 . The motion supporting system according to claim 12 , further comprising a display device mounted with the informer.

18 . An motion supporting device that acquires body motion information of an exercising player, collects dynamic information of an implement related to the exercise, and determines, on the basis of the body motion information and the dynamic information, timing for informing the player of advice.

19 . The motion supporting device according to claim 18 , wherein the body motion information is measured by a body motion sensor worn on the player.

20 . The motion supporting device according to claim 19 , wherein the body motion information includes at least one of acceleration information and angular velocity information generated according to a movement of the player.
