Case digitalo – a range of virtual and augmented reality solutions in construction application
Abstract: We describe a range of Virtual and Augmented Reality (VR/AR) solutions applied during the planning and construction of VTT’s new head offices, the Digitalo (“Digital House”) in Espoo, Finland. During the building phase as well as in later evaluations 2003-2006, the various approaches used for Digitalo’s visualisation included: radiosity rendering by still images; immersive virtual reality visualisation; mobile outdoors augmenting; augmented scale model; augmented web camera; 3D landscapes; and interior design by means of virtual and augmented reality. We employed various display devices ranging from HMD video glasses to CAVE screens, and from PDA’s to varying kinds of PC solutions. Some of our solutions, for example the augmented web camera and scale model systems, have not been previously presented and they appear here for the first time. Also, we describe the current status of the applied methods, as well as directions for future research. Altogether, we believe this case study to be among the most comprehensive ones in the world to include such a wide variety VR/AR techniques applied in a single building project.
Keywords: virtual reality, augmented reality, CAVE, HMD, web cameras, mobile computing, feature detection, markers, tracking, tangible user interfaces

Why interactive multi-disciplinary collaboration in building design is better than document based design
Abstract: This paper presents a theoretical framework of Interactive Multi-Disciplinary Collaboration (IMDisCo) for building design. This framework puts the whole design and communicative process into a project-based problem solving setting that is compatible to today's supply chain management framework. It also offers a set of evaluation methods based on (1) quality, and (2) cost of the design. An analysis of the framework shows that IMDisCo offers more design options than the conventional approach of document based design. With the help of suitable technology, the turn-around-time of design in IMDisCo can be shorter than the conventional approach. And thus the (theoretical) optimal design quality (cost) can be higher (lower) than the document based design. Three critical success factors for the framework have been presented. Finally, this paper discusses the future work of establishing the IMDisCo framework as an industry framework. In the longer term, the emerging new software that supports goal setting, design and evaluation will further enhance the paradigm shift of interactive multi-disciplinary design.
