An analysis system S includes a sensor unit 1 and a processing device 2. The sensor unit 1 is installed on a lower back portion of a user. The processing device 2 includes a swing evaluating section 254. The swing evaluating section 254 extracts a first peak waveform and a second peak waveform in an output result of an angular speed measured by a sensor installed on the lower back portion of the user. The swing evaluating section 254 evaluates the motion of the user on the basis of an extraction result. ## Claims ### Claim 1 A device for evaluating motion of a user, the device using angular speed data outputted from a mountable sensor, the sensor being mounted on a buttock of the user, the device comprising: a memory; and a processor, wherein the processor executes a program stored in the memory 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 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. ### Claim 2 (depends on 1) The device according to claim 1, wherein the processor further performs operations comprising: in a case in which the waveform is determined to be of the double-mountain type, outputting the evaluation information in relation to appearances of a waveform of the first peak and a waveform of the second peak. ### Claim 3 (depends on 1) The device according to claim 1, wherein the processor further performs operations comprising: in a case in which the waveform is determined to be of the single-mountain type, outputting motion information for the waveform to become the double-mountain type. ### Claim 4 (depends on 3) The device according to claim 3, wherein the device further comprises a communication unit that performs communication with the sensor, and the processor outputs the motion information acquired by the communication unit from the sensor. ### Claim 5 (depends on 1) The device according to claim 1, wherein the processor further performs operations comprising: in a case in which the waveform is determined to be of the mountain range type, outputting motion information for the waveform to become the single-mountain type. ### Claim 6 (depends on 5) The device according to claim 5, wherein the device further comprises a communication unit that performs communication with the sensor, and the processor outputs the motion information acquired by the communication unit from the sensor. ### Claim 7 (depends on 1) The device according to claim 1, wherein the processor outputs advice information as the evaluation information. ### Claim 8 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. ### Claim 9 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.
