An Electrostatic Capacitive Floor Sensor System for Human Position Monitoring in a Living Space

This paper presents a prototype of electrostatic capacitive floor sensor system with low-cost, easy-installation and maintenance-free advantages for monitoring human position in a living space. Features of the sensor system are conciseness that the system is made of very simple parts, that means it is inexpensive, and modularity that enables easy expansion of the sense area. Experiments confirmed the sensor characteristics for human monitoring and showed the feasibility of the accurate sensing with only concise recognition and filtering processes. keywords: Electrostatic capacitive sensor, Human position monitoring, Intelligent environment, Sensor network, Ambient intelligence
