Abstract

A motion analysis device, a motion analysis method and a motion analysis program that make it possible for an operator to improve his or her motions more smoothly are provided. The motion analysis device includes an acquisition part that relates to motions of a plurality of parts of an operator and acquires time-series data relating to an operation performed by an operator and; an analysis part analyzing the time-series data and generating motion data indicating a type of elemental motion and an execution time of the elemental motion from start to end thereof; an evaluation part evaluating the elemental motion performed by the plurality of parts based on an execution timing of the elemental motion; and a display control part performing control to differentiates periods corresponding to different elemental motions and display the evaluation together with the motion data on a display part.

First claim

What is claimed is:

1. A motion analysis device comprising a processor configured to:
relate to an operation performed by an operator and acquire time-series data relating to motions of a plurality of parts of the operator;
analyze the time-series data and generate motion data indicating a type of elemental motion and an execution time of the elemental motion from a start to an end thereof;
evaluate the elemental motion performed by the plurality of parts based on a timing of execution of the elemental motion; and
control to differentiate periods corresponding to different elemental motions and display an evaluation together with the motion data on a display part.

2. The motion analysis device according to claim 1 , wherein the time-series data relating to the plurality of parts includes time-series data relating to a left hand and a right hand, and
the processor gives a high evaluation in a case where the elemental motion is executed in parallel using the left hand and the right hand.

3. The motion analysis device according to claim 1 , wherein the processor gives a low evaluation in a case where none of the plurality of parts performs a motion relating to the operation.

4. The motion analysis device according to claim 2 , wherein the processor gives a low evaluation in a case where none of the plurality of parts performs a motion relating to the operation.

5. The motion analysis device according to claim 1 , wherein the processor performs control to display an icon indicating the evaluation along the motion data on the display part.

6. The motion analysis device according to claim 2 , wherein the processor performs control to display an icon indicating the evaluation along the motion data on the display part.

7. The motion analysis device according to claim 1 , wherein the processor performs control to display the motion data in different display modes according to the evaluation on the display part.

8. The motion analysis device according to claim 2 , wherein the processor performs control to display the motion data in different display modes according to the evaluation on the display part.

9. The motion analysis device according to claim 1 , wherein the processor performs control to display a comment indicating the evaluation together with the motion data on the display part.

10. The motion analysis device according to claim 2 , wherein the processor performs control to display a comment indicating the evaluation together with the motion data on the display part.

11. A motion analysis method comprising:
relating to a plurality of parts of an operator, and acquiring time-series data relating to an operation performed by the operator and;
analyzing the time-series data and generating motion data indicating a type and an execution time of an elemental motion;
providing an evaluation of the elemental motion performed by the plurality of parts based on a timing of execution of the elemental motion; and
performing control to display the evaluation together with the motion data on a display part so as to be capable of differentiating periods corresponding to different elemental motions.

12. A non-transitory computer-readable recording medium that stores a motion analysis program causing a processor included in a motion analysis device to execute:
relating to a plurality of parts of an operator and acquiring time-series data relating to an operation performed by an operator;
analyzing the time-series data and generating motion data indicating a type and an execution time of an elemental motion;
performing an evaluation of the elemental motion performed by the plurality of parts based on a timing of execution of the elemental motion; and
performing control to display the evaluation together with the motion data on a display part so as to be capable of differentiating periods corresponding to different elemental motions.
