Description

technical field

[0001] The present invention relates to an apparatus and method for measuring an amount of exercise, and more particularly, the present invention relates to an apparatus and method for measuring an amount of exercise by using an acceleration sensor. Background technique

[0002] As is well known in the art, a pedometer is a tool for measuring a person's physical activity. A pedometer is a portable tool that counts steps and measures calorie expenditure by detecting a person's physical activity. Such pedometers are classified into mechanical pedometers and electronic pedometers.

[0003] When a person walks or runs, the mechanical pedometer counts the number of steps by measuring the number of vertical vibrations of a pendulum housed in the mechanical pedometer. However, if the mechanical pedometer is placed in a user's clothes pocket or hung around the user's neck, the mechanical pedometer may not be able to accurately measure the...
