Abstract :
This paper shows a methodology of estimating a user´s everyday energy expenditure using a 3-axis accelerometer of a mobile phone handset. We first infer the user´s posture based on the acceleration sensor reading and calculate METS value, which is considered as a measure for estimating calorie consumption for daily activities. The experimental result shows that our application is as accurate as a reference device.
