The vision of iACT is to research, develop and evaluate tools, strategies and metaphors to better understand and support ways to interact effectively with large, immersive displays. Thus, the project aims at providing users with new, intuitive ways to make sense of normally unstructured and hardly comprehensible information, to share their insights with others and develop new ones by working as a team. To achieve this goal, a large part of research will be to develop intuitive visualization metaphors for large displays and explore more natural techniques to interact with information represented on a large scale display.
