本文描述了如何对物理世界进行检测，使对象能够进行自我描述，传达其身份、几何形状以及其他信息（例如历史记录或用户注释）。支持技术是无线标签，充当射频身份和几何（RFIG）应答器。我们展示了如何在无线标签中添加光电传感器，从而显着扩展其功能以允许几何操作，例如查找标签的 3D 位置，或检测标记对象形状的变化。标签数据通过使用手持式区域设置感知移动投影仪直接投影呈现给用户。我们引入了一种称为交互式投影的新技术，允许用户与投影信息进行交互，例如导航或更新投影信息。使用带有有源射频 (RF) 标签的对象演示了这些想法。但这项工作的动机是无动力无源 RFID 的出现，这项技术有望对现实世界的应用产生重大影响。我们讨论了我们当前的原型在未来如何发展为无源 RFID。
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 as a radio frequency identity and geometry (RFIG) transponder. We show how addition of a photo-sensor to a wireless tag significantly extends its functionality to allow geometric operations - such as finding the 3D position of a tag, or detecting change in the shape of a tagged object. Tag data is presented to the user by direct projection using a handheld locale-aware mobile projector. We introduce a novel technique that we call interactive projection to allow a user to interact with projected information e.g. to navigate or update the projected information.The ideas are demonstrated using objects with active radio frequency (RF) tags. But the work was motivated by the advent of unpowered passive-RFID, a technology that promises to have significant impact in real-world applications. We discuss how our current prototypes could evolve to passive-RFID in the future.
