Recognition of complex human activity using mobile phones: a systematic literature review

Abstract

Using mobile phones for Human Activities Recognition (HAR) is very helpful in providing a personalized support system for healthcare management and general wellbeing of the user. Many studies have been published which have investigated the HAR with the help of mobile phones. But, in these studies, the researchers briefly mentioned the complex HARs and did not provide any discussion or comparison with the models used. In our study, we have carried out a systematic review of the currently used models in the Complex HAR. We have been carrying out an automatic search in 4 digital libraries since 2012, to address four research questions in our study. We found 11 primary studies after applying the included - excluded criteria. Further studies need to be carried out in this area, especially for solving the issue of a trade-off between the recognition accuracy and the computational load.
