The Smart Jigsaw Puzzle Assistant: Using RFID Technology for Building Augmented Real-World Games Juergen Bohn Institute for Pervasive Computing, ETH Zurich bohn@inf.ethz.ch Abstract Radio Frequency Identification (RFID) can be used as technology for coupling the physical and the virtual world in ubiquitous computing environments. In this paper, we show that RFID is also a very interesting option for building augmented real-world games. First, we describe several advantages of employing RFID technology for the development of gaming applications. Then we present the Smart Jigsaw Puzzle Assistant, a fully operational augmented jigsaw puzzle game which we have developed and prototypically implemented using miniature RFID tags and a palm-sized RFID scanner.
