title A Digital Design Coach for Young Designers
source Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 330-335
summary The present use of digital media in architectural practice and education is primarily focused on representation, communication of ideas and production. Designers, however, still use pencil and paper to assist the early conception of ideas. Recently, research into providing digital tools for designers to use in conceptual designing has focused on enhancing or assisting the designer. Rarely has the computer been regarded as a potential teaching tool for design skills. Based on previous work by the author about visual thinking and the justification for a digital design assistant, the intention of this paper is to illustrate to the reader the feasibility of a digital design coach. Reference is made to recent advances in research about design computability. In particular, research by Mark Gross and Ellen Do with respect to their Electronic Cocktail Napkin project is used as a basis on which to determine what such a digital coach may look and feel like.

title Understanding and Assisting CAD Users in the Real World
source Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 209-227
summary In spite of the rapid increase in functionality and resources provided by CAD systems, productivity growth expected from their use has been difficult to achieve. Although many surveys describe this "productivity puzzle", few studies have been conducted on actual CAD users to understand its causes. In an effort to understand this issue, the first author visited a federal architectural office and observed CAD users in their natural setting using ethnographic techniques developed by cultural anthropologists. This paper describes preliminary results obtained from the study. The study revealed that users had leveled-off in their learning and experimentation and were using the CAD system in sub-optimal ways. The authors argue that this sub-optimal usage occurs because users have limited ways to learn better or different ways of executing tasks. The authors propose that CAD systems should provide active assistance, that is, intervene spontaneously with advice, assistance, and relevant information while the user interacts with the system. They conclude with some issues revealed by the study that should be considered when developing such active assistance.

title Supporting information navigation in generative design systems
source Camegie Mellon University, School of Architecture
summary Generative design systems make it easier for designers to generate and explore design altematives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed to enable designers to access the information with ease. Such aids may improve the usability of generative design systems and encourage their use in architectural practice. This dissertation presents a comprehensive approach to support navigation in generative design systems. This approach takes account of studies related to human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. It contains a general model of design space, basic navigation operations, and principles for designing navigation support. The design space model describes how the space may grow and evolve along predictable dimensions. The basic operations facilitate navigation activities in this multi-dimensional design space. The design principles aim at guiding system developers in creating navigation utilities tailored to the needs of individual design systems. This approach is validated through prototype implementations and limited pilot usability studies. The validity of the design space model and basic navigation operations is examined through the development of a design space navigation framework that encapsulates the model and operations in a software environment and provides the infrastructure and mechanisms for supporting navigation. Three prototype navigation tools are implemented using this framework. These tools are subjected to usability studies. The studies show that these tools are easy to leam and are efficient in assisting designers locating desired information. In summary, it can be demonstrated that through the prototype implementations and usability studies, this approach offers sufficient support for the design and implementation of navigation aids in a generative design system. The research effort is a pioneer study on navigation support in generative design systems. It demonstrates why navigation support is necessary; how to provide the support; and what types of user interaction it can offer. This research contributes to information navigation studies not only in the specific domain of generative design system research, but also in the general field of human-computer interaction.

title JCAD-VR: Java Collaborative Architectural Design Tool in Virtual Reality - A Java3D based scalable framework for real-time, multiplatform VR environments
source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 454-459
summary This paper proposes a framework that provides the architect with a tool that uses Virtual Reality (VR) as part of the design path. It offers the possibility to deploy a system capable of assisting the design profession during the early stages of the design process. This way VR becomes the means for a new experience where the architect can, free from constraints of the 2D world, create and manipulate the space she/he is designing. The idea upon which JCAD-VR is being built is that all the users present in the virtual world have to be able to share the same virtual environment in a “transparent fashion” where the user interface, instead of the traditional menu/windows based layout, it is part of the virtual world itself. The aim is to provide the designer with a tool for creating 3D-shapes in a shared VR environment, thus allowing the design to be shared as it evolves.

title A Computational Framework for Theater Design
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 165-182
summary This paper presents the results of an ongoing research on computational methods for the design of theatrical spaces. We demonstrate a systemic approach to design supported by a set of digital tools implemented for assisting the process. The primary purpose of the framework is to establish a formal basis for expressing and exploring explicit design criteria. At this stage the framework enables us to metrically access a range of design metrics that traditionally have been addressed through primarily architectural narrative. Moreover, our method strives in establishing a background where knowledge can be explicitly encoded and the results of analytical methods can be additively employed. In the future, the framework will assist as the platform for experimenting with generative or query-based design processes empowered by computation. We structured this paper / framework around three conceptual units: (a) a design intent toolkit assisting the processes of rapidly generating theater configurations; (b) an analytical system that evaluates a range of design metrics centered about aspects of visual comfort; and (c) a post-processing and visualization unit that binds the design metrics with existing data / studies and provide a range of representation methods. Overall, the methodology adopts existing knowledge in theatrical design, challenges traditional ideas of understanding the theater and proposes methods for evaluating its architectural performance. The conclusions focus on highlighting both the limitations and the potential of our system in the process of theater design. We also extend outside the boundaries of the current research into a brief discussion on the methodological impact of digital technology in architectural research. Finally we propose areas of future research and development.

title Analysis of design communication with and without computer mediation
source Proceedings of Co-designing 2000, pp. 329-337
summary With recent developments in CAD and communication technologies, the way we visualise and communicate design representations is changing. A matter of great interest to architects, practitioners and researchers alike, is how computer technology might affect the way they think and work. The concern is not about the notion of 'support' alone, but about ensuring that computers do not disrupt the design process and collaborative activity already going on (Bannon and Schmidt, 1991). Designing new collaborative tools will then have to be guided by a better understanding of how collaborative work is accomplished and by understanding what resources the collaborators use and what hindrances they encounter in their work (Finholt et al., 1990). Designing, as a more abstract notion, is different than having a business meeting using video conferencing. In design it is more important to 'see' what is being discussed rather than 'watch' the other person(s) involved in the discussion. In other words the data being conveyed might be of more importance than the method with which it is communicated (See Kvan, 1994). Similarly, we believe that by using text instead of audio as a medium for verbal communication, verbal representations can then be recorded alongside graphical representations for later retrieval and use. In this paper we present the results of a study on collaborative design in three different environments: face-to-face (FTF), computer-mediated using video conferencing (CMCD-a), and computer-mediated using "talk by typing" (CMCD-b). The underlying aim is to establish a clearer notion of the collaborative needs of architects using computer-mediation. In turn this has the potential in assisting developers when designing new collaborative tools and in assisting designers when selecting an environment for a collaborative session.

title A framework to integrate generative design techniques for enhancing design automation
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 127-136
summary This paper presents and demonstrates a computational framework that facilitates the integration of different generative design techniques to enhance design automation. The framework is based on the evaluation and comparison of four main generative design algorithms. Effectiveness of the framework is demonstrated through an example scenario. Compared to most existing generative design systems that are based on one of the techniques, which often bias the generative design process in a certain direction, new generative design systems by applying the proposed framework will provide the trigger at each stage as demonstrated in the example scenario for the designer to perceive the emergent designs from different viewpoints. This advantage will enhance design generation and automation by assisting the designer in making more informed decisions in understanding and selecting the suitable generative techniques for different design needs.

title Towards a Sketching Tool for Architects: 3D Reconstruction of Polyhedron
source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 132-135
summary This paper presents a tool for assisting 3D modeling from perspective projections. The proposed system uses a projective geometry engine capable of rebuilding a 3D model from a set of lines and geometric constraints. A dialogue interface assists the user in expressing geometric constraints. The system finds out the relevant geometrical components in the sketch and automatically posts the constraints. The system is limited to rebuilding polyhedrons. If we can deduce, from a perspective sketch of a polyhedron, the planar constraints of the faces and the parallelism constraints of the edges that meet in the same vanishing points, the geometric engine will be able to build a 3D model of the polyhedron.

summary This paper presents research in computer modeling that ARIAM team of the school of architecture of Paris La Villette has been developing for several years. One of the aims of this research group is to develop computer systems that assist architects in modeling existing buildings or monuments from heterogeneous documents or data as drawings plans, sections, photos, measures taken on site etc. In spite of advances in computer recognition it’s a long way to have a system that could automatically recognize, from any bitmap document or photo, relevant architectural objects and automatically build the model these documents represent. However, if we could define a knowledge base about a particular domain, it would be possible to develop a system that could interpret specific documents that represent some kind of building or monuments. But, even in such limited domain, it is difficult to build an exhaustive knowledge base and user-interactions are generally required. We argue that a user could mark relevant information on the documents and thus facilitate the process of interpreting. The system we propose has three components: a graphical user interaction tool, an analyzer of documents and user interactions, and a generative tool that produces the required model. As an illustration, the paper presents a system we have developed which assists an architect in modeling a 3D mesh of gothic vaults for a finite elements analysis.

summary The aim of this work is to present some reflexions raised when designing teaching materials in hypermedia formats for architecture. We plan to work with the essential notions for design, creation and use of hypermedia technology in either traditional and/or distance learning. While doing this, we will go deep in the use of some tools of hypermedia design. We will go from formal models such as abstraction, taking as an example the use of video games, to interface elements. We will present different concepts that should be applied in the design of hypermedia; they help in assisting the user to discover and to increase his knowledge. We intend to promote an effective user. We aim to assess design emphasizing the ludic experience, according to what exists in the market and to the two works on hypermedia design from the author."

title An Information-based Framework for Composites Design
source Drexel University
summary The heterogeneity of composites determines that composite materials can be engineered to better satisfy a specific design requirement. The main problems that have hindered the application of composites are the need for the material and manufacturing design to be conducted simultaneously, the involvement of a large number of design factors, the difficulty in the characterization of composites, and the inherent repetition of the design process. Considering these problems, this thesis presents an information-based framework for composites design. This research consists of four main aspects: (1) The development of a heterogeneous CAD modeling algorithm and an integrated CAD/CAE method, and their application in a unit cell-based characterization of composite materials with a complex fiber form; (2)The development of a unit cell database for improving the material and manufacturing process design, which covers the design of its database model and the access strategies based on the logic architecture of unit cells and the relationships among elements of unit cells and with the environments; (3)The design of an Information-Based Design Support System (IBDSS) to support the composites design by using the unit cell database, in which the blackboard framework is adopted for the system to organize various computer techniques for different design stages, and to support the design iterating to satisfactory ones incrementally and efficiently, and the data structure of the blackboard, the algorithm to control design iterations, and design procedures for every stage are studied; and (4) The introduction of a ranking-based unit cell evaluation methodology and effective ranking factors for facilitating and improving the composite design process. The approach improves the efficiency of composites design by automating design iterations, supporting composite characterization, alleviating the cost of composite material and manufacturing method design, and assisting in tailored material selection. Case studies are presented to show how the IBDSS is applied to support composites design.

title HalO [Indoor Positioning Mobile Platform]: A Data-Driven, Indoor-Positioning System With Bluetooth Low Energy Technology To Datafy Indoor Circulation And Classify Social Gathering Patterns For Assisting Post Occupancy Evaluation
source ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 284-291
summary Post-Occupancy Evaluation (POE) as an integrated field between architecture and sociology has created practical guidelines for evaluating indoor human behavior within a built environment. This research builds on recent attempts to integrate datafication and machine learning into POE practices that may one day assist Building Information Modeling (BIM) and multi-agent modeling. This research is based on two premises: 1) that the proliferation of Bluetooth Low Energy (BLE) technology allows us to collect a building user’s data cost-effectively and 2) that the growing application of machine learning algorithms allows us to process, analyze and synthesize data efficiently. This study illustrates that the mobile platform HalO can serve as a generic tool for datafication and automation of data analysis of the movement of a building user. In this research, the iOS mobile application HalO, combined with BLE beacons enable building providers (architects, developers, engineers and facility managers etc.) to collect the user’s indoor location data. Triangulation was used to pinpoint the user’s indoor positions, and k-means clustering was applied to classify users into different gathering groups. Through four research procedures—Design Intention Analysis, Data Collection, Data Storage and Data Analysis—the visualized and classified data helps building providers to better evaluate building performance, optimize building operations and improve the accuracy of simulations.
