摘要: This paper describes how to instrument the physical world so that objects become self-describing, communicating their identity, geometry, and other information such as history or user annotation. The enabling technology is a wireless tag which acts radio frequency identity geometry (RFIG) transponder. We show addition of photo-sensor significantly extends its functionality allow geometric operations - finding 3D position tag, detecting change in shape tagged object. Tag data presented by direct projection using handheld locale-aware mobile projector. introduce novel technique we call interactive interact with projected e.g. navigate update information.The ideas are demonstrated active (RF) tags. But work was motivated advent unpowered passive-RFID, promises have significant impact real-world applications. discuss our current prototypes could evolve passive-RFID future.
