Abstract: Activity recognition is one of the most promising research topics in pervasive computing applications. In general, activity recognition techniques mainly focus on the direct observation of people and their behaviors with the help of cameras or wearable sensors. Recently, device-free activity recognition has drawn much attention since it does not require subjects to wear any devices. An RFID based, device-free activity recognition system is developed by leveraging off-the-shelf, pure passive RFID tags and exploiting easy-to-obtain RSSI signal. The common issues related to RFID such as sensitivity to environment and false negative readings are taken care of in this system. The proposed system interprets the activity performed by a person by deciphering the signal fluctuations obtained from the RFID tags using machine learning algorithms. A dictionary-based approach is devised to learn a compact set of dictionaries for the activities. This system achieves efficient and robust activity recognition via a more compact and robust representation of activities. With recent advances in embedded sensors and wireless technologies, it has become possible to develop a wide range of applications such as surveillance, ambient assisted living, remote health monitoring and intervention, fall detection and ambulatory monitoring.
