Motion analysis device, motion analysis method and recording medium

A motion analysis method comprising:

• 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 execution time of an elemental motion;
• excluding data corresponding to a stop period of the operator which is taken until an initial elemental motion is started from the motion data, and generating shortened motion data;
• and
• performing control to differentiate periods corresponding to different elemental motions and display the shortened motion data on a display part.

A non-transitory computer-readable recording medium that stores a motion analysis program causing a calculation part included in a motion analysis device to function as:

• an acquisition part that acquires time-series data relating to an operation performed by an operator;
• an analysis part that analyzes the time-series data and generates motion data indicating a type and execution time of an elemental motion;
• a generation part that excludes data corresponding to a stop period of the operator which is taken until an initial elemental motion is started from the motion data, and generates shortened motion data;
• and
• a display control part that performs control to differentiate periods corresponding to different elemental motions and display the shortened motion data on a display part.
