In this paper, we propose a framework which provides the temporal and spatial context for daily routine inferring in an ambient-assisted-living environment equipped with several sets of passive infrared (PIR) sensors. The inferred information could help identify the user's daily pattern and abnormalities from long-term monitoring. We implemented the prototype of the system from the electric parts...
Feature extraction is a critical stage in human activity recognition. The information carried in features directly affects the classification performance. This paper explores a new group of features for activity recognition, which have not been broadly applied in previous works in this field. The newly introduced features are related to the attitude of the on-body devices, being extracted from both...
Data preprocessing, feature selection and classification algorithms usually occupy the bulk of surveys on human activity recognition (HAR). This paper instead gives a brief review on the data acquisition which is a critical stage of the wearable data-driven-based HAR. The review focuses on the determination of sensor types, modality of sensor devices, sensor deployment and data collection. The work...
