Determining activity using a triaxial accelerometer
Merryn J Mathie, Nigel Hamilton Lovell, Adelle C.F. Coster, Branko George Celler · 2002
Triaxial accelerometers have been employed to monitor human movements in a variety of circumstances. It is necessary, however, to be able to extract useful information from the acceleration measurements. We show that we can, in a controlled environment, use an energy expenditure method to identify and separate dynamic activities, including changes in posture and ambulation.
