Multi-User Participation on Large-Screens – The example of Collaborative Voting

Abstract

The features of a prototype and their empirical background are presented to demonstrate how multi-user interaction of a single large screen can be practically employed for complex design tasks. The prototype refers to the field of collaborative modeling and supports the creativity phase where relevant elements of a process have to be identified. Developing and using the prototype leads to a list of recommendations and proposals for improvement which serve as heuristics for the development of similar solutions where large interactive surfaces can be collaboratively used.
