DEVICE AND METHOD FOR ESTIMATING THE ENERGY EXPENDITURE OF A PERSON

摘要

The present invention relates to device for estimating the energy expenditure of a person with an increased accuracy. The proposed device comprises a movement sensor (12) for detecting physical activity of the person and for generating a movement signal (13), a heart rate sensor (14) for detecting the heart rate of the person and for generating a heart rate signal (15), an estimation unit (16) for estimating the energy expenditure of the person from said movement signal (13) and/or said heart rate signal (15), and a control unit (18) for controlling said estimation unit (16) to switch between an non-activity mode in which only the movement signal (13) is used for estimating the energy expenditure if no physical activity of the person has been detected and an activity mode in which the movement signal (13) and/or the heart rate signal (15) is used for estimating the energy expenditure if physical activity of the person has been detected.
