Motion evaluation device using angular speed measured by a wearable sensor

A method for evaluating motion of a user, using angular speed data outputted from a sensor mounted on a buttock of the user, the method comprising:

• acquiring a waveform of a rotating speed of a lower back of the user from time-series data indicating a time change of the rotating speed of the lower back of the user which is the angular speed data measured by the sensor;
• determining whether the acquired waveform corresponds to one of a plurality of waveform types, the plurality of waveform types including:
• (i) a double-mountain type including a first peak and a second peak, (ii) a single-mountain type including one peak, and (iii) a mountain range type including continuous wiggle mountains;
• outputting evaluation information which is information in relation to evaluation of the rotating speed of the lower back of the user according to a waveform type determined from among the plurality of waveform types.

A non-transitory computer-readable storage medium having stored thereon a program which, when executed by a computer connected to a sensor mounted on a buttock of a user, causes the computer to perform operations comprising:

• acquiring a waveform of a rotating speed of a lower back of the user from time-series data indicating a time change of the rotating speed of the lower back of the user which is angular speed data measured by the sensor;
• determining whether the acquired waveform corresponds to one of a plurality of waveform types, the plurality of waveform types including:
• (i) a double-mountain type including a first peak and a second peak, (ii) a single-mountain type including one peak, and (iii) a mountain range type including continuous wiggle mountains;
• outputting evaluation information which is information in relation to evaluation of the rotating speed of the lower back of the user according to a waveform type determined from among the plurality of waveform types.
