In this article, the authors present MUG, a collaborative 3D environment to support knowledge-based conceptual design. This work integrates computer-aided and collaborative design methods with a representation framework being developed for the Semantic Web. In this work, the authors have created a unique environment that allows a group of users, working together over the Internet, to create both a 3D layout and a knowledge-based description of a conceptual product design. MUG accepts domain-specic engineering ontologies described with the DARPA Agent Markup Language (DAML) and provides a multimodal collaborative 3D environment, supporting shared audio and shared 3D manipulation. MUG is written entirely in the Java language and runs across a wide variety of hardware and operating system platforms.
