摘要
During the last years, the need to assess the physical activity with objective and reliable methods has become more apparent. This is due to the essential role physical activity plays in the development and therapy of some of the most important chronic diseases. Activity monitors are able to measure several parameters of physical activity based on acceleration sensors. In the past years these devices have become the standard instrument in the objective assessment of physical activity in everyday life. Accordingly, the main parameter for evaluating the physical activity of a person is the energy expenditure (EE). However, the most common methods for calculating EE have some serious restrictions that could lead to errors in the prediction. An improvement could be reached by classifying the actual type of activity and choosing a specific model to calculate the energy expended. Beside this, the use of additional information from other sensors could increase the precision of the algorithm. This paper summarizes the current state of research in accelerometry and proposes future research areas and development approaches.
