Today in terms of security and caring, more various and robust information system about human existence in indoor environment (ex. rooms, buildings) are needed. Especially, human position estimation system in such kinds of spaces is basic. Generally, such kind of systems use radiowave devices, cameras and ultrasonic devices to estimate human position. But these kind of systems have some weakpoint...
In this paper, a novel human position estimation system using electric-field resonance coupling is proposed. There are various advantages of using electric-field for human position estimation system. The system is robust to illumination change, body-worn tags are not required and sensors could be hidden since electric-field can path through an insulator. Tags are not required because the system estimates...
