Elmanakhly Department of Mathematics, Faculty of Science,Suez Canal University, Ismailia, Egypt Ahmed Fathalla Spatio-temporal human activity recognition (HAR) is an emerging field that uses spatial and temporal data to identify and classify human activities accurately. It has been effectively applied in areas like healthcare for monitoring daily activities, detecting anomalies, and aiding rehabilitation with real time feedback. However, there is a gap in research specifically focusing on integrating spatio temporal data with advanced machine and deep learning techniques for HAR based on sensor data. Existing reviews do not comprehensively cover spatio-temporal HAR based on sensor data, resulting in a lack of summaries on recent models, datasets, sensor technologies, applications, and machinedeep learning techniques used in this field. This systematic review provides a comprehendsive overview of spatio-temporal HAR based on sensor data, tracing its development from the origin of sensor-based spatio-temporal HAR field to the present. It highlights the main challenges in spatio- temporal HAR. The review also examines model trends over the years, including the distribution of models used in HAR and the identification of those frequently combined to form hybrid models. Additionally, it analyzes accuracy trends of the commonly used datasets and identifies the datasets that are widely used in spatio-temporal HAR research. Furthermore, various application domains and sensor technologies used in spatio-temporal HAR are identified. 2025 2025 286 307 10.54216/JISIoT.160221 https://www.americaspg.com/articleinfo/18/show/3739
