Many interactive user interfaces require the location and orientation of the user. Recently massively distributed RFID tags are being used in location aware system by attaching RFID reader to mobile robot or a person.[Bohn and Matter 2004] [Scooter and Helal 2004] These applications use RFID tags in position detection methods, in which physical coordinates are correlated with RFIDs by using a mapping table. Although such application of RFID technology has high potential, implementing such a system in physical space using conventional methods is expensive and time consuming. To resolve these problems, we have developed an RFID textile which is able to be woven commercially using a conventional loom.
