Rap ID: A Framework for Fabricating Low Latency Interactive Objects with RFID Tags
RFID tags can be used to add inexpensive, wireless, batteryless sensing to objects. However, quickly and accurately estimating the state of an RFID tag is difficult. In this work, we show how to achieve lowlatency manipulation and movement sensing with offtheshelf RFID tags and readers. Our approach couples a probabilistic filtering layer with a montecarlosamplingbased interaction layer, preserving uncertainty in tag reads until they can be resolved in the context of interactions. This allows design
