Knowledge at your Fingertips :Multi-touch interaction for GIS and architectural design review applications

This paper introduces novel techniques of interacting and controlling 3D content using multi-touch interaction principles for navigation and virtual camera control. Based on applications from GIS and for the architectural design review process, implementation and usage of these interaction techniques are illustrated. A compre-hensive hardware and sofhvare setup is used, which not only includes tracking, but also an X3D based layer to simplify application development. Therefore it allows designers and other non-programmers to develop multi-touch applications very efficientlv, while allowing to focus on user interaction and content.
