Virtual Reality in the Design Studio: the Eindhoven Perspective Henri Achten, Walther Roelen, Jan-Thijs Boekholt, Arthur Turksma, Joran Jessurun Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-up of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work. Keywords: Virtual Reality; Design studio; Student projects Historical context computer usage and the use of the CAAD-tools mentioned above. The Calibre Institute was founded in 1988 by the Shortly after this first period the development of Faculty of Architecture, Building and Planning of PC’s and PC-based applications reached such a level Eindhoven University of Technology. The main goal that they also could be used for CAAD. From that for this Institute was to perform research and time on ‘standard’ CAAD-applications like AutoCad education on the combination of computer science and MicroStation were explored and used in and architecture. At the time the Institute started its education. These programs were first designed to work, the only computer applications that could directly facilitate 2D-drawing but over times more and more be used in the field of architecture, building and 3D features were built in. The development of CAAD- planning were Computer Aided Design (CAD) tools was stopped in the Institute and focus changed programs. These programs ran on main-frames and to the application and adaptation of commercially minis with graphical terminals attached. In available CAAD-programs. Calibre also started combination with Abacus (an institute of the University research and did developments on many other of Strathclyde, Glasgow Scotland) where prof.

The Institute in combination with the calculation were developed (Bouwplan, 1990). To Building-Informatics group started courses in basic investigate the possibilities and to facilitate the Architectural Computing: The Education Process 169 educational tasks of the group, Calibre also developed programs could serve two purposes. First the computer-aided-learning programs (CalInCAD early prediction of illumination, luminance and colour helps 1990’ies, Geberit bathroom program 1998, 1999). to create buildings with better performance and higher Because the purpose of the Institute also was to comfort in respect to lighting.

VR: First steps When in the early nineties Virtual Reality Systems The building-industry is one of the few industries that became commercially available Calibre did not lack the possibility of using full-scale prototypes to hesitate to invest in VR hard- and software. Virtual evaluate and test their designs. Until then the only Reality held the promise to develop into a tool for means to communicate designs to other partners in intuitive, interactive and realistic evaluation of (non-) the process of building and to the customers and existing three-dimensional environments. In fact designers themselves, were sketches, drafts Calibre bought one of the first systems that were drawings, artist-impressions and small-scale mock- produced by Division.

Using this seemed to open possibilities to overcome at least part transputer-based system the possibilities of VR in of this problem. A lot of effort was put into the research, architectural design were investigated. The poor development and adaptations of these programs to performance of such systems combined with the make them suitable for the use in our context. Filters relative low quality of the peripherals made them and converters were written to facilitate the use and unusable for direct application in the architectural re-use of design related data, especially for practice. But the system gave Calibre the opportunity visualisation purposes. At the same time simulation to investigate future possibilities, to participate in the programs were developed to evaluate the technical development of the next generation systems and to aspects of buildings.
