COMIC ESPRIT BASIC RESEARCH PROJECT 6225 Demonstrator prototypes of Computational Mechanisms of Interaction Abstract The present report documents the research activities undertaken in Task 3.3 of the COMIC project. The objective of the three years of research of Strand 3 is to de- velop a conceptual foundation for designing computational mecha- nisms of interaction for CSCW applications that can support the complex task of articulating distributed cooperative activities. The present deliverable presents various prototype systems based on the architecture and notation for constructing computational mechanisms of interaction. Each contribution focuses on one aspect of the work presented in previous deliverables. Finally, reference material and usage scenarios for each prototype are included.
