Physical activity is a very important indicator of healthy lifestyle. Physical activity recognition, classification and evaluation is a significant research area, both in academic as well as in healthcare domain to help patients achieving the benefits of performing physical activities. Physical activity recognition and evaluation enable professionals to make appropriate decisions and interventions, and patients can manage their activities of daily living independently.
