A generic framework for cyber-physical web

In this paper, we propose a generic and unified content framework for cyber-physical Web, namely the Web incorporating physical objects without tag-based identifiers. The most important contribution of our framework is a novel cyber-physical-web page mechanism allowing for organizing a collection of related physical objects. We design a new lightweight XML-based markup language to describe real world objects, like HTML does digital objects in cyber world. In addition, our framework addresses a number of key issues in the development of cyber-physical Web. To improve the accuracy and efficiency of physical object identification, a sophisticated representation of physical objects is supported in our framework. Furthermore, a hybrid localization method is implemented to provide seamless positioning during the navigation of cyber-physical Web from outdoor space to indoor environment or vice versa. We also develop a cyber-physical Web browser prototype on the Android platform.
