Abstract

To record physical activity and the amount of exercise, a CPU 130 calculates the user'"'"'s heart rate while exercising from a pulse wave signal output from a pulse wave sensor unit 102 and an acceleration signal output from a acceleration sensor unit 140, calculates the number of steps taken by the user, and displays the results on an LCD 108. The CPU 130 continuously counts the number of steps based on the acceleration signal from the acceleration sensor unit 140, and displays the total number of steps taken by the user in one day on the LCD 108.
