A wearable device attached to a subject includes an accelerometer that measures acceleration information, and a biological sensor that measures biological signal information of the subject. From the measured acceleration information and biological signal information, first feature data corresponding to a first predetermined period and second feature data corresponding to a second predetermined period are extracted. By machine learning based on the first feature data, a dynamic/static activity identification model, a dynamic-activity identification model, and a static-activity identification model, for the subject, are generated. By combination of results of determination based on each of the identification models, a posture and an activity of the subject are identified and correspondence information, which associates the identified posture and activity with the biological signal information of the subject, is generated.

An electronic scale includes a display unit for digitally displaying the weight of a load on a weighing dish, a tare subtraction key, a display control unit for controlling the display on the display unit and a memory for memorizing a zero adjustment range. The display control unit displays on the display unit a tare subtraction prompt display for prompting to push the tare subtraction key when the measurement value of the load increases over the upper limit of the zero adjustment range.
