Estimation device, estimation system, estimation method, and recording medium

An estimation method executed by a computer, the method comprising:

• extracting, from a gait waveform extracted from time series data of sensor data based on a motion of a foot of a user, a feature amount according to an attribute of the user in a section in which a feature of a physical condition according to the attribute of the user appears;
• and
• estimating the physical condition of the user using the feature amount extracted according to the attribute of the user.

A non-transitory program recording medium storing a program for causing a computer to execute:

• a process of extracting, from a gait waveform extracted from time series data of sensor data based on a motion of a foot of a user, a feature amount according to an attribute of the user in a section in which a feature of a physical condition according to the attribute of the user appears;
• and
• a process of estimating the physical condition of the user using the feature amount extracted according to the attribute of the user.
