While designing and discussing exhibitions in science centers, common conceptual framework is needed. This paper provides a framework based on participation, virtuality, and collaboration, and two models - a Rubik's cube model and a Scatter plot space. They are suitable tools for analysis and overview of existing and planned exhibitions, as well as for conceptual analysis during the design process. The classification and the models for the interaction have been developed in a research by design process, where 45 prototypes have been designed, exhibited and tested.
