Determining the Position and Orientation of Multi-Tagged Objects Using RFID Technology

The idea of smart shelves or tables equipped with RFID technology has been around for some time now. A number of commercial products are already available, especially for retailing. All presented solutions, however, are designed to only identify objects currently in range. While this may be sufficient for some applications, there are others that do not only require identification, but furthermore the exact position and orientation of the objects. In this paper, we present an approach to determine the position and orientation of multi-tagged objects. We introduce the general idea, describe our developed system, and present preliminary findings. We also summarize our next steps and describe a planned evaluation
