Design of a Component-Based Augmented Reality Framework
Proceedings of The Second IEEE and ACM International Symposium on Augmented Reality (ISAR 2001), pp. 45-54. (bib)

In this paper, we propose a new approach to building augmented reality (AR) systems using a component-based software framework. This has advantages for all parties involved with AR systems. A project manager can reuse existing components in new applications; an end user can reconfigure his system by plugging modules together; an application developer can view the system at a high level of abstraction; and a component developer can focus on technical problems. Our proposed framework consists of reusable distributed services for key subproblems of AR, the middleware to combine them, and an extensible software architecture. We have implemented services for tracking, modeling real and virtual objects, modeling structured navigation or maintenance instructions, and multimodal user interfaces. As a working proof of our concept, we have built an indoor and outdoor campus navigation system using different modes of tracking and user interaction.

Herding Sheep: Live System Development for Distributed Augmented Reality
Proceedings of The Second International Symposium on Mixed and Augmented Reality (ISMAR 2003), pp. 123-132. (bib)

In the past, architectures of Augmented Reality systems have been widely different and taylored to specific tasks. In this paper, we use the example of the SHEEP game to show how the structural flexibility of DWARF, our component-based Distributed Wearable Augmented Reality Framework, facilitates a rapid prototyping and online development process for building, debugging and altering a complex, distributed, highly interactive AR system. The SHEEP system was designed to test and demonstrate the potential of tangible user interfaces which dynamically visualize, manipulate and control complex operations of many inter-dependent processes. SHEEP allows the users more freedom of action and forms of interaction and collaboration, following the tool metaphor that bundles software with hardware in units that are easily understandable to the user. We describe how we developed SHEEP, showing the combined evolution of framework and application, as well as the progress from rapid prototype to final demonstration system. The dynamic aspects of DWARF facilitated testing and allowed us to rapidly evaluate new technologies. SHEEP has been shown successfully at various occasions. We describe our experiences with these demos.

Integrating Studierstube and DWARF
International Workshop on Software Technology for Augmented Reality Systems. Tokyo, Japan, Oct. 7, 2003 (bib)

Studierstube and DWARF are modular Augmented Reality frameworks, each with distinct advantages in different application areas. Both can easily be extended by adding new components. In this case study we show how new components can act as a bridge between the frameworks. By facilitating the exchange of basic data types such as pose and user input, the frameworks become interoperable. This allows us to build new applications leveraging the advantages of both frameworks, while fostering cooperation between research groups.

Decentralized Coordination of Distributed Interdependent Services
IEEE Distributed Systems Online -- Middleware Work in Progress Papers, June 2003 (bib)

Current middleware technology for ubiquitous computing connects mobile computers to services in the environment. This is often insufficient because it doesn't address the issue of services depending on other services. The DWARF framework offers a decentralized approach to configuring and coordinating interdependent services.
