Issues of Human Activity Recognition in Healthcare

Human activity recognition substantiates itself as a useful tool applicable in many smart assistive technologies. Gathering, evaluating, and analyzing data in order to recognize human activities poses many issues, especially in healthcare applications. This paper seeks to answer the question what are the issues regarding the human activity recognition process in healthcare. After conducting a review of approaches used to implement each stage of a specific activity recognition process, the results indicated that issues mostly arise in data collection stage. Based on that, the applicability of related approaches (i.e., wearables, smartphones, and non-contact sensing) is discussed. Underlying issues are identified in order to serve as a starting point for future research activities.
