Wearable RFID Based Real Time Activity Recognition System

摘要

In the past couple of years, there is growing interest in passive UHF RFID technology. Activity recognition plays an important role in many applications. One of such applications is care of old people that are supported by activity recognition systems. In this paper a wearable radio frequency identification (RFID) system using passive tags which are smaller and more cost-effective to recognize human activities in real-time scenario are used. Backed up by a step-down transformer for power supply to the circuit, the tilt and fall detection sensors, walking and running activities can be traced out in this project. These RFID tags are arranged at the room premises and when a person enters a specific room, it alerts by special commands. We exploit RFID radio patterns using passive RFID tags to check the person's position and his presence in a particular location.
