MEASUREMENT DEVICE, MEASUREMENT METHOD, AND PROGRAM

A measurement device includes: an accelerometer; a storage; and at least one processor. In accordance with instructions stored in the storage, the processor acquires data of an acceleration waveform during walking or running of a user from the accelerometer, identifies a time width between a first timing and a second timing based on the acceleration waveform, and counts steps based on the acceleration waveform. The acceleration waveform changes from a negative value to a positive value at the first timing. The acceleration waveform changes from a positive value to a negative value at the second timing. When a predetermined condition is satisfied in counting the steps, the processor counts the acceleration waveform whose time width is greater than a predetermined threshold as two steps and count the acceleration waveform whose time width is smaller than the predetermined threshold as one step.
