Abstract

Information representing an activity intensity computed from a measured step count is transmitted from a first pedometer to a second pedometer as step count-related information. In the second pedometer, walking compatibility is determined based on the difference between the activity intensity in the first pedometer and the activity intensity in the second pedometer, and the determination result is displayed on both pedometers.
