RFID Textile and Map Making System for Large Area Positioning

We present a process for the development of an RFID textile, and have developed a map making system to support highly accurate position detection. Massively distributed RFIDs have the potential for location aware applications however time and cost are high for the deployment of the RFID tags, and correlation of the physical coordinates with each ID for making a map. We developed an RFID woven textile and a customized textile inspection machine with an automatic map making function. These developments have the potential to extend location aware systems with massively distributed tags. We examine the feasibility of a tracking system with RFID textile by using 19-meter coated textile as a carpet to the laboratory room and corridor. The system was calibrated in 38 mins and achieved a 10cm resolution.

Development of RFID Textile and Human Activity Detection Applications

We developed RFID woven textile and a customized textile inspection machine with an automatic map making function. These developments have potentials to extend location aware systems in real use. In this paper, we present a process of the development of RFID, the developed map-making system and an accuracy of the automatically made map and time saving effect. And we outlined two prototypes of human activity detection using RFID textile. One is a pilot application of a tracking system using 19-meter coated RFID textile as a carpet. A persons tracking is detected by shoes that RFID readers were embedded. Another one is a pilot application of a human-activity tracking system using RFID textile wear. By wearing it, the predefined behaviour is detected by embedded RFID readers in the environment. In section 6 conclusions and future works are discussed.

Development of RFID textile for location aware system

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.
