Apparatus and method for measuring quantity of physical exercise using acceleration sensor

Abstract

The present invention provides a method for measuring quantity of exercise and an apparatus comprising an acceleration sensor for generating acceleration information by measuring the quantity of exercise according to user movement, sensor control unit for supplying power to the acceleration sensor and sampling the acceleration information generated from the acceleration sensor, a dynamic energy measurement unit for converting the sampled acceleration information into dynamic energy, comparing a local maximum value with a predetermined threshold value if an ascending gradient of the dynamic energy has the local maximum value exceeding a pre-determined value and determining a user step if the local maximum value exceeds the predetermined threshold value, a calorie consumption measurement unit for calculating calorie consumption by analyzing an energy level of dynamic energy determined as a user step, a memory for storing information, and a display section for displaying information related to the number of steps and calorie consumption.

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...

AI Technical Summary

Problems solved by technology

In addition, the pedometer must continuously check the movement of a person, therefore, the pedometer must be continuously kept on, which results in high power consumption

[0006] Usually, pedometers measure and display the amount of daily exercise, therefore, pedometers cannot manage the number of steps and calorie consumption accumulated over a long period of time

That is, the pedometer has a compact size, so it is difficult to maintain the pedometer in a small size for a pedometer for accumulating and managing the amount of daily exercise, weekly exercise, and monthly exercise according to the user's needs
