RFID Localization for Tangible and Embodied Multi-User Interaction with Museum Exhibits

摘要

RFID is usually used for identification but with some postprocessing it can also be used for localization. These properties expand the typical range of possible interactions with digital displays in museums. Our goal is to encourage the collaborative investigation of a rich information space presented on an Ambient Display in a museum exhibit. We consider two different models of interacting with an exhibit: Tangible Control, wherein passive RFID tags are embedded in some artifacts and multiple users can control the information on the screen by moving those artifacts, and Embodied Control, wherein people directly carry an RFID tag and interact with the information by walking within the simulation space. Each model has different implications for how the visitors might relate (a) to the information being displayed, and (b) to one another. Here we present preliminary results on the suitability of a single-reader and passive tag setup for providing localization input.
