A context-a ware and augmented reality-supported service framework in ubiquitous environments

Abstract

We present a Context-Aware and Augmented Reality-supported service Framework for distributed and collaborative interactions in Ubiquitous environments (U-CAFÉ). The proposed approach adopts semantic web-based context management and reasoning for supporting context-aware services. Further, it utilizes augmented reality for providing more relevant and human-centered interactions and collaborations. A semantic web representation language, Topic Map, is used to manage and reason about ubiquitous service-related contexts explicitly and systematically. Augmented reality-based interactions are used for embedding virtual models onto physical models considering contexts and for enabling bi-augmentation between virtual and physical models. The proposed framework has been successfully applied to design collaboration and intelligent home services. © IFIP International Federation for Information Processing 2005.
