We present an interactive workspace featuring hand gesture recognition that allows multiple users to collaborate in the creation of a concept map. The workspace integrates web-based and face-to-face scenarios in knowledge-building activities, brainstorming and problem solving sessions. A wiki serves as the repository for knowledge elements, which are presented to co- located users in form of a concept map projected on a meeting table. A computer vision module recognizes multiple hands and fingers on the table surface from an overhead camera, using fingertip detection and tracking algorithm, and map elements can be manipulated using a natural gesture language. Also smart devices, like PDAs or tablets, can be connected to the system and participate in the interaction with their local input. The concept map and the wiki are synchronized in real-time, providing notifications to both co- located and distributed users, allowing a community shared awareness that enhances and enriches the knowledge building experience.
