Abstract

An exercise support device of the present invention includes a sensor section which obtains motion data related a user'"'"'s body motion while exercising, and a data processing section which identifies whether the motion data obtained by the sensor section are related to first motion of swinging the right foot toward a traveling direction or related to second motion of swinging the left foot toward the traveling direction, and obtains, from the motion data, first exercise data related to the first motion and second exercise data related to the second motion. The data processing section analyzes the user'"'"'s body motion based on comparison between the user'"'"'s exercise form and the exercise status based on the first exercise data and the user'"'"'s exercise form and the exercise status based on the second exercise data.

Claims

1. An exercise support device comprising:

a sensor section which obtains motion data related to a body motion of a user while exercising; and

a data processing section which identifies whether the motion data obtained by the sensor section are related to first motion of the user swinging a right foot toward a traveling direction or related to second motion of the user swinging a left foot toward the traveling direction, and obtains, from the motion data, first exercise data related to the first motion and second exercise data related to the second motion.

2. The exercise support device according to claim 1, wherein the sensor section obtains, as the motion data, acceleration data corresponding to acceleration in an extending direction of a body axis of the user and angular velocity data corresponding to angular velocity of a rotating motion along the body axis in a rotating direction, and

wherein the data processing section identifies whether the motion data are related to the first motion or related to the second motion, based on a value of the acceleration data and polarity of a value of the angular velocity data at specific timing.

3. The exercise support device according to claim 2, wherein the data processing section sets, as the specific timing, timing at which the value of the acceleration data indicates a predetermined change corresponding to a motion of the user landing with one of the right foot and the left foot with respect to time.

4. The exercise support device according to claim 1, wherein the data processing section obtains changes to time progress of an exercise form and an exercise status of the user corresponding to the first motion and changes to time progress of an exercise form and an exercise status of the user corresponding to the second motion, based on the obtained first exercise data and the obtained second exercise data;

and analyzes the body motion of the user based on comparison between the changes to time progress of the exercise form and the exercise status corresponding to the first motion and the changes to time progress of the exercise form and the exercise status corresponding to the second motion.

5. The exercise support device according to claim 1, wherein the data processing section measures a plurality of exercise cycles corresponding to cycles of motions of the left foot and the right foot of the user in the motion data, and detects changes in an exercise form and an exercise status of the user based on comparison of a value of the motion data for each of the exercise cycles.

6. The exercise support device according to claim 5, wherein the data processing section performs normalization processing for correcting a time length of each of the plurality of exercise cycles to an equal time length, and detects changes in the exercise form and the exercise status based on comparison of the value of the motion data for each of the exercise cycles whose time lengths have been corrected by the normalization processing.

7. The exercise support device according to claim 1, further comprising:

an information providing section which provides the user with exercise support information for supporting a way of moving a body while exercising,

wherein the data processing section judges, based on the motion data, whether or not an exercise form and an exercise status of the user are each in a specific state set in advance, and generates a notification signal in accordance with a judgment result, and

wherein the information providing section provides predetermined notification information based on the notification signal as the exercise support information.

8. The exercise support device according to claim 7, wherein the information providing section visually, tactually, or aurally provides the user with the exercise support information.

9. The exercise support device according to claim 7, wherein the data processing section analyzes changes in the exercise form and the exercise status while exercising, and

wherein the information providing section provides the exercise support information to the user while exercising.

10. The exercise support device according to claim 1, further comprising:

a storage section which stores the motion data obtained by the sensor section at any time,

wherein the data processing section analyzes the body motion of the user after the exercise is ended, based on the motion data stored in the storage section.

11. The exercise support device according to claim 10, further comprising:

an information providing section which provides the user with exercise support information for supporting a way of moving a body while exercising,

wherein the sensor section, the storage section, the data processing section, and the information providing section are directly or indirectly connected to a network, respectively,

wherein the data processing section receives the motion data stored in the storage section via the network, and analyzes the way of moving the body of the user based on the received motion data, and

wherein the information providing section receives a result of analysis by the data processing section via the network, and provides the user with the exercise support information based on the received analysis result.

12. An exercise support method comprising:

a step of obtaining motion data related to a body motion of a user while exercising; and

a step of identifying whether the obtained motion data are related to first motion of the user swinging a right foot toward a traveling direction or related to second motion of the user swinging a left foot toward the traveling direction, and obtaining, from the motion data, first exercise data related to the first motion and second exercise data related to the second motion.

13. The exercise support method according to claim 12, wherein acceleration data corresponding to acceleration in an extending direction of a body axis of the user and angular velocity data corresponding to angular velocity of a rotating motion along the body axis in a rotating direction are obtained as the motion data, and

wherein whether the motion data are related to the first motion or related to the second motion is identified based on a value of the acceleration data and polarity of a value of the angular velocity data at specific timing.

14. The exercise support method according to claim 13, wherein timing at which the value of the acceleration data indicates a predetermined change corresponding to a motion of the user landing with one of the right foot and the left foot with respect to time is set as the specific timing.

15. The exercise support method according to claim 12, wherein changes to time progress of an exercise form and an exercise status of the user corresponding to the first motion and changes to time progress of an exercise form and an exercise status of the user corresponding to the second motion are obtained based on the obtained first exercise data and the obtained second exercise data, and

wherein the body motion of the user is analyzed based on comparison between the changes to time progress of the exercise form and the exercise status corresponding to the first motion and the changes to time progress of the exercise form and the exercise status corresponding to the second motion.
