title	Collaborative Conceptual Modeling Using the SKETCH Framework
source	Proceedings of IASTED International Conference on Computer Graphics and Imaging, 154-158
summary	This paper introduces NetSketch, an application that supports distributed conceptual design by providing tools for modelessly creating, manipulating and viewing 3D models in a shared virtual space. Inherent problems exist with collaborative design tools because of the simultaneous group interaction required for users to smoothly and effectively work together in the same virtual space. With NetSketch, we provide solutions to these problems by providing a fast and direct gesture-based user interface, a set of visual effects that better enable a user's awareness of operations done by other participants, and a set of tools for enhancing visual communication between participants.

summary	On a number of occasions after telling people about Corporate Design Foundation and what we do, their reaction is “well, business now understands the importance of design, right?” The answer is yes and no. There is, as they say, good news and bad news. A growing number of senior business executives do understand the possibilities of design. But many still do not. Unfortunately, the majority of mid-level managers do not. While there has been an increasing amount written about design in the business press, there has also been an equal amount in the general press which is misleading or just wrong. There is a great deal more to do.

title	CHARACTERISTICS OF ARCHITECTURAL DESIGN-TOOLS
source	Proceedings of the 4rd European Full-Scale Modelling Conference / Lausanne (Switzerland) 9-12 September 1992, Part B, pp. 7-14
summary	The professional roles and fonctions of architects are linked to the societal context in which they practice. Furthermore, this context, which is not static, has a relationship to the ways in which institutions, groups and individuals are involved in processes for the design and construction of the built environment. This presentation illustrates how the roles and functions of architects, other professionals, their clients and the general public have a bearing on the tools and methods used by the architectural profession to simulate design projects. Traditionally, sketches, renderings and pattern books were used. Then, they were supplemented by axonometric and perspective drawings, written and diagrammatic specifications, photographs and small-scale models. In recent decades mathematical models of diverse kinds, simulation techniques -including small- and full-scale modelling kits -as well as computer aided design and drafting systems have been used. This paper briefly presents these kinds of tools and then presents a typology of them. In conclusion, possible applications for the future are discussed.

title	SIMULATIONS OF ARCHITECTURAL PROJECTS: METHODS AND APPLICATIONS AT FULL-SCALE
source	Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 53-64
summary	This paper briefly examines five interrelated themes concerning the use of full-scale simulation models in architectural projects, in the context of research and professional practice. First, the meaning of design is discussed. Second, a multi-functional interpretation of building performance is presented. Third, the main reasons for simulating design projects, in general, and for using full-scale models, in particular, are summarized. Then the antecedent or prerequisite conditions for public participation to occur effectively are discussed. Finally, an overview of the use of full-scale simulation models in European workshops enables us to table four ma n classes of functions for full-scale models.

title	Computers, words and pictures
source	Design Studies 18: 171-183
summary	The paper discusses the problem of CAD in architectural design from the point of view of aiding creativity. It argues that so far there is no real evidence that this has been achieved. An explanation for this is offered and the authors suggest that more work needs to be done on how we hold conversations about design. The authors also conclude that, at least until design conversations are better understood, we should concentrate less on pictures and more on words. A first attempt to develop a computer-aided design conversation system is described.

title	How designers think: the design process demystified
source	University Press, Cambridge
summary	How Designers Think is based on Bryan Lawson's many observations of designers at work, interviews with designers and their clients and collaborators. This extended work is the culmination of twenty-five years' research and shows the author's belief that we all can learn to design better. The creative mind continues to have power to surprise and this book aims to nurture and extend this creativity. This book is not intended as an authoritative description of how designers should think but to provide helpful advice on how to develop an understanding of design. 'How Designers Think' will be of great interest, not only to designers seeking a greater insight into their own thought processes, but also to students of design in general from undergraduate level upward.

summary	This contribution discusses the benefits of panoramic representations for projects relating to the digital-heritage, a method which allows for an effective presentation and exploration of spatial relationships in structures that no longer exist. The paper provides information on existing software options for the creation of panoramic views. State-of the art representations of this kind derived from a 3D computer model will be discussed on the basis of a case study relating to the destroyed synagogue of Jablonec in the Czech Republic.

summary	Collaborative virtual environments clearly have potentials to enable innovative and effective education, involving debate, simulation, role play discussion and brain storming and project based group work etc. Integration of the collaborative virtual environments into the design curricula offers significant potentials for design schools. In this paper, based on our previous teaching in collaborative virtual environments, the student’s perceptions and evaluations of the courses, we discuss the pedagogy of design teaching in collaborative virtual environments, considering what skills the new generation of designers should have in terms of collaboration, communication and design.

title	Robotic Construction by Contour Crafting: The Case of Lunar Construction
source	International Journal of Architectural Computing vol. 10 - no. 3, 423-438
summary	Contour Crafting is a digitally controlled construction process invented by Professor Behrokh Khoshnevis that fabricates components directly from computer models, using layered fabrication technology. By obviating the need for formwork used in traditional concrete construction, CC can reduce costs and construction times significantly. The technique has great potential as a robotic form of construction reliant on relatively minimal human labor as a form of construction in relatively hazardous environments, such as the Moon with its radiation levels that can prove highly damaging. Current research funded by NASA has been exploring the potential for using CC on the Moon to build structures making use of readily available regolith that is found in great abundance on the surface of the Moon. This article offers an overview of this research and evaluates the merits of using CC on the Moon.

summary	The works Acusma and Microfônico by the group Chelpa Ferro not only represent an inflexion point in the group's trajectory but also make reference and allow an interpretation which places Chelpa Ferro amongst several other artists who experimented with sound-noise throughout the 20th century. Since the first modernists sound was object of artistic experiments, always informed by technological innovations. Thus the group inserts itself in such context and augments it, appropriating theirselves of everyday objects to produce their sound or by creating their own specially built apparatuses to amplify inexistent sounds, as in the works here discussed.

summary	The proper knowledge and appraisal of our cultural inheritance as well as its consistent diffusion are respected and powerful tools to safeguard it. The possibilities offered by a georeferenced of our cultural inheritance by means of GIS as well as its integration with multimedial resources such as images, animation,digitized video,voice an sound of aregional scope constitute a valuable tool having a significant potential in the study, protection and diffusion of our cultural inheritance. The objective of the present proposal is to show by way of a GIS application that presents georeferenced information of the province of San Juan, an integration of written documents, sound documents (popular music), folkloric elements (images) and digitized videos about the cultural inheritance of eminent places of the province of San Juan, that we are more committed ourselves to preserve due to their peculiar aridity characteristics and highly seismical risk. Some personalized icons displaying the afore mentioned resources are incorporated into the GIS application. The GIS-database presents an field destined to give data regarding the information source consulted about the inheritance.

title	From an architectural sketch to its semantic representation
source	The Int. Journal of Construction IT 4(2), pp. 67-84
summary	This paper presents an essay on the needs and viability of the semantic harnessing of architectural sketches in the framework of integrated computer design. A symbolic and relation representation is proposed as the shared architectural model. This is structured with the practical proposals of cognitive sciences about knowledge creation and manipulation. An experiment is described which observes and analyses the composition of professional sketches. Its results are taken as directives to build the architectural model content. Two computer software are presented as prototypes for managing a case base of architectural knowledge and deducing the semantic concepts from sketches. Back to Search Results

source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 15-31
summary	In this paper, we present our latest research related to the concept of a sketchinterface. After describing our vision of computer assisted design and the conditions necessary for its effective implementation, an original data model is presented, which covers different levels of representation and is grounded in a database of implicit information. We then describe our software prototype, which exploits the potentials of the digital sketch, in order to demonstrate how our ideas are pertinent and the feasibility of three kinds of applications. In particular, we argue in favor of using an architectural software program in relation to the sketch within the same computer assisted environment at an early stage in the design process.

title	iSphere: A Proximity-based 3D Input Interface
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 281-290
summary	This paper presents a 24 degree of freedom input device for 3D modeling. iSphere uses the proximity information of pulling-out and pressing-in capacitive sensors to manipulate 12 control points of a 3D surface simultaneously . The iSphere dodecahedron is demonstrated manipulating an analog parametric model with high-level modeling concepts like push or pull the 3D surfaces. Our pilot experiment shows that iSphere saved many steps of selecting the control point and going through menus. Experts were used to those extra steps and still found themselves doing them but novices saved significant time for surface shaping tasks. 3D systems are benefited to execute high-level modeling commands, but lacking of fidelity is a great issue of analog input device.

title	Developing a User Location Prediction Model for Ubiquitous Computing
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 215-224
summary	Our prediction model is based on the development of “Semantic Location Model.” It embodies geometrical and topological information which can increase the efficiency in prediction and make it easy to manipulate the prediction model. Data mining is being implemented to extract the inhabitant's location patterns generated day by day. As a result, the self-learning system will be able to semantically predict the inhabitant's location in advance. This context-aware system brings about the key component of the ubiquitous computing environment. First, we explain the semantic location model and data mining methods. Then the location prediction model for the ubiquitous computing system is described in details. Finally, the prototype system is introduced to demonstrate and evaluate our prediction model.

summary	This paper presents a rule-based mechanism for mediating design processes in a web-based collaborative environment. This mechanism is developed based on a logical description of flexible declarative inter-dependency relationships between collaborative design activities. We address design coordination problems by focusing on overlapping problem solving within dynamic workflow. A system prototype is presented to demonstrate our approach. This prototype is part of "DECADE", a long-term project to develop the needed technologies supporting design collaboration.

title	BIM-Enabled Regulatory Design Rule Checking for Building Circulation
doi	https://doi.org/10.52842/conf.caadria.2024.1.211
source	Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 1, pp. 211–220
summary	Automated design rule checking (RDC) in Building Information Modelling (BIM) can be challenging especially when dealing with qualitative aspects and intricate regulations like building circulation. The study proposes a novel method for Regulatory Design Rule Checking (RDRC) for building circulation, addressing challenges in translating regulations to computational constructs and extracting relevant information from complex BIM models. Through a tiered compliance assessment, the investigation considers preventive rule-based checks for doors and corridors and explores constraint-based regulatory incentive schemes such as through-block pedestrian links (TBPL). The RDRC analysis identifies non-compliance and concludes with a recommendation for potential adjustments. This work aims to benefit designers and regulators, providing productivity enhancements and a deeper understanding of regulatory intricacies in the context of building circulation.

title	Location of a Point in a Planar Subdivision and its Applications
source	SIAM Journal of Computing. September, 1977. vol. 6: pp. 594-606 : ill. includes bibliography
summary	Given a subdivision of the plane induced by a planar graph with n vertices, in this paper the problem of identifying which region of the subdivision contains a given test points is considered. A search algorithm, called point-location algorithm, which operates on a suitably preprocessed data structure is presented. The search runs in time at most O((log n)2), while the preprocessing task runs in time at most O(n log n) and requires O(n) storage. The methods are quite general, since an arbitrary subdivision can be transformed in time at most O(n log n) into one to which the preprocessing procedure is applicable. This solution of the point location problem yields interesting and efficient solutions of other geometric problems, such as spatial convex inclusion and inclusion in an arbitrary polygon
