title	Designing with images: Augmented reality supported on-site Trompe l’oeil

summary	Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A look at current computer aided applications reveals a serious lack of IT support for the whole architectural design process with and within existing buildings (e.g. building surveying, designing on site and the preparation of information for further use in later planning stages). An ongoing interdisciplinary research project undertaken jointly by the faculty of media and the faculty of architecture is investigating methods and techniques for the computer-aided support of the design process with and within existing buildings. The goal is to develop a hardware and software concept for a “design-toolbox” based on SAR (spatial augmented reality) and to implement aspects of it as prototypes. The paper focuses on one aspect of the research project – designing with images in an AR-Environment. The paper presents an overview of the project, a description of the core model based on a client-server architecture, the historical / theoretical architectural background and first results of this research part. The project is funded by the “German Research Foundation (DFG)”.

title	Constraint-Based Design in Participatory Housing Planning
doi	https://doi.org/10.52842/conf.ecaade.2007.687
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 687-694
summary	The research presented in this paper deals with the yet unexplored development of a constraint-based design strategy to support participatory housing planning processes in Latin America. The article discusses the implementation criteria of a constraint satisfaction approach to solving the building bulk design problem. This elementary problem to the architecture practice, is concerned with the synthesis of the boundary geometry from the volume, shape and allocation of the building and any part thereof located inside a given zoning lot. A legal solution to a building bulk design problem is a building cubature that complies with all the applicable bulk regulations. The case study applies to the common class of single-family house units produced in Chile and the regulatory framework implemented there. Two different computer implementation criteria are being tested in an ongoing series of trials. The first, and most extensively developed, makes use of Maxon’s XPresso® visual scripting environment to set up a semi-automated controllable design environment that allows to create parametric feature-based 3D models of building bulk solutions. The second approach is currently being tested by using Ilog’s OPL Studio® constraint programming environment to achieve fully automated search and 2D graphic visualization of the complete set of solutions to separate subdomains of the bulk problem.

title	Looking Back to the Future
doi	https://doi.org/10.52842/conf.ecaade.2007.285
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 285-292
summary	In the early and mid 1990s the idea to apply CBR to the task of designing — in short Case-Based Design (CBD) — led to a considerable number of research initiatives across the world. Several promising CBD tools and prototypes were developed and enthusiastically celebrated within the research community, seemingly announcing a promising future for CAAD. However, because the predicted breakthrough failed to appear, an in-depth evaluation of six CBD tools was conducted in 2001 in search of reasons for this limited success. At first sight the situation has not changed much since then, yet a closer look reveals CBD research still to be quite active, be it sometimes disguised. This observation, combined with our belief in CBD’s potential for aiding professional and student architects, motivated an expanded issue of the 2001 study. This issue determines the position of current CBD research within the CAAD domain and uncovers focal points set by CBD researchers and the tools they created. Additionally it analyses the role of emerging technologies in overcoming earlier identified drawbacks of CBD tools in architecture.

title	Simulating the Atmosphere of Spaces
doi	https://doi.org/10.52842/conf.ecaade.2007.169

summary	At present more than half of all building activity in the German building sector is undertaken within existing built contexts. Work in existing building fabric is an essential aspect of most architects’ activities. The development of a conceptual and technological basis for the digital support of design directly on site, in and with the available architecture is the main focus of the research project “Spatial Augmented Reality for Architecture”. This article describes one part of the research project: the sampling of colours and materials at a scale of 1:1 using Augmented Reality technologies. This makes it possible to project the colour and material qualities of a design directly onto any surface within an existing building, geometrically corrected. A first software prototype SAR-CA has been developed and then assessed using a user study to obtain a first evaluation of the prototype to determine the direction of future research. Future research areas are discussed at the end of the paper.
