IMPROVE: Advanced Displays and Interaction Techniques for Collaborative Design Review

In this paper we present evaluation results of an innovative application designed to make collaborative design review in the architectural and automotive domain more effective. Within IMPROVE, a European research project in the area of advanced displays, we are combining high resolution multi-tile displays, TabletPCs and head-mounted displays with innovative 2D and 3D Interaction Paradigms to better support collaborative mobile mixed reality design reviews. Our research and development is motivated by application scenarios in the automotive domain involving FIAT Elasis from Naples, Italy and in the architectural domain involving Page/Park architects from Glasgow, Scotland. User evaluation took place at Glasgow (UK), Naples (ITA) and Darmstadt (GER), where we tested the integrated IMPROVE prototype application. The tests were conducted based on several heuristics such as ergonomics and psychomotorial factors and they were conducted based on guidelines recommended by ISO 9241 to verify whether the developed interfaces were suitable for the applications scenarios. Evaluation results show that there is a strong demand for more interactive design review systems, allowing users greater flexibility and greater choice of input and visualization modalities as well as their combination.
