이 휴대용 칼로리 측정기는 질량의 갖는 추가 사람의 움직임에 의해 진동할 때 그 진동수를 측정하고, 측정된 진동수로부터 입력된 사용자의 신체정보와 비교하여 칼로리 소모량을 계산하는 방식이다.The portable calorimeter measures the frequency of vibration when a person moves with an additional person of mass and calculates the calorie consumption by comparing the user's body information with the measured frequency.
그런데 이와 같은 종류의 칼로리 측정기는 인체의 움직임으로부터 단순히 진동수만을 측정하여 칼로리 소모량을 계산하는 것으로, 사람의 큰 움직임과 작은 움직임을 구분하지 않고 동일한 운동량으로 계산하게 되므로, 사람의 정확한 칼로리 소모량을 측정할 수 없는 문제점이 있다.However, this kind of calorie measure simply calculates the calorie consumption by simply measuring the vibration frequency from the movement of the human body, and calculates the exact calorie consumption of a person because it calculates the same amount of exercise without distinguishing between large and small movements of a person. There is no problem.
본 발명은 종래의 문제점을 개선하기 위하여 안출한 것으로, 본 발명의 목적은 사람의 운동에 의해 발생되는 진동의 수뿐만 아니라 진동의 세기도 측정하여 디스플레이를 통해 휴대폰 등의 사용자의 정확한 운동량 및 칼로리 소모량을 표시해 주기 위한 것이다.The present invention has been made to improve the conventional problems, the object of the present invention is to measure the intensity of vibration as well as the number of vibrations generated by the movement of a person through the display of the exact amount of exercise and calories burned by the user It is to display.
