For work modelling and task-based interactive systems design we propose a modelling concept and usage scenario that should help to increase effectiveness in organization and technology development. The Tangible Task Modelling Demonstrator (TTMD) facilitates the representation and development of work and task models by means of MiMs. Using the TTMD users can directly grasp and manipulate work tasks. As a result, the cognitive load for modelling and (re-)arranging elements of work spaces can be reduced.enText/Workshop Paper
