Motion recognition device and motion recognition method

A motion recognition method of which a process is executed by a computer, the process comprising:

• classifying a plurality of frames including positional information of a feature point that corresponds to a predetermined part or a joint part of a body of a subject into a plurality of groups in time series by segmenting the plurality of frames in time series based on a position of the predetermined part of the body of the subject,
• identifying, for a respective group, a type of a basic motion that corresponds to the respective group, based on movement of the feature point included in a consecutive frame;
• and
• evaluating, for the respective group, a skill and a difficulty level of the movement indicated by the respective group, by using a criteria identified by both of a first basic motion type and a second basic motion type, the first basic motion type being the type of the basic motion identified for the respective group, the second basic motion type being the type of the basic motion identified for a group one before the respective group,
• wherein the evaluating is configured to evaluate, for each group, a score of the respective group by comparing features of the feature points included in the frame of the respective group with evaluation criteria, the evaluation criterion being information indicating a respective score corresponding to each feature indicated by feature points to be included in frames.
