IMPROVE: Advanced Displays and Interaction Techniques for Collaborative Design Review.
ABSTRACT 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 D 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.

ABSTRACT: A system was developed for the creation of urban scenarios pro-duced on large screen displays using laser pointers as input devices and supporting collaborative usage. A novel interface had to be de-veloped to support interaction with such input devices, based on the concept of gates and circular menus with a non-intrusive interface. Users can navigate on a virtual world using a set of comprehen-sive navigation modes, namely: first person, bird's eye view and examine modes, along with a multimodal flight mode controlled by speech commands and arm tracking. Simple shapes can be created and modeled using a minimalistic set of modeling tools, defining a novel modeling interface. Buildings can be instantiated from a li-brary of facade styles by drawing the desired blueprint and setting the facade height to generate unique buildings. Additional styles may be implemented by making use of a developed XML format for defining façade layout rules. Buildings and other shapes can be transformed and cloned. Objects in the scene can have notes at-tached to them to aid in reviewing sessions. An alternative building creation work flow is proposed to take advantage of this system for early prototypes and showcasing projects.11/2008;
