title	Structure and Flow of Design Information in the Construction Process
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	At every step in the construction process different individuals (architects, engineers, project managers and workmen) make use of design information, yet the requirements they have for the contents and structure of this information are radically different. This paper makes some general observations on the structure, productions and manipulation of design information, concentrating specifically on the form in which information is passed between individuals, the relationship between graphic and text based information, and the interaction between design information and materials flows in the constructions supply chain. On the basis of these observations, this paper presents a general conceptual framework for describing the information flow with the aim of understanding and controlling it. Within this framework, some conceptual tools are proposed thatcan be used to structure design information including abstraction, dependent relationships, and control and identify hierarchies. Next, this paper illustrates how one company, Matura Nederland, has used these concepts and tools to develop design processes and computer software to integrate its operational process from design to installation. Finally, some suggestions are made as to how these ideas relate to some current developments in CAD, database and process control software.

title	Hand-Eye Coordination in Virtual Reality, Using a Desktop Display, Stereo Glasses and a 3-D Mouse
doi	https://doi.org/10.52842/conf.caadria.1997.073
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 73-82
summary	Many virtual-reality displays augment the user’s view of the real world but do not completely mask it out or replace it. Intuitive control and realistic interaction with these displays depend on accurate hand-eye coordination: the projected image of a 3-D cursor in virtual space should align visually with the real position of the 3-D input device that controls it. This paper discusses some of the considerations and presents algorithms for coordinating the physical and virtual worlds.

summary	With the advent of social networks, it became apparent that the social aspect of designing and learning plays a crucial role in students’ education. Technologies and skills are the base on which learners interact. The ease of communication, leadership opportunity, democratic interaction, teamwork, and the sense of community are some of the aspects that are now in the centre of design interaction. The paper examines Virtual Design Studios (VDS) that used media-rich platforms and analyses the influence the social aspect plays in solving all problems on the sample of a design studio at Deakin University. It studies the effectiveness of the generated social intelligence and explores the facilitation of students’ self-directed learning. Hereby the paper studies the construction of knowledge via social interaction and how blended learning environments foster motivation and information exchange. It presents its finding based on VDS that were held over the past three years.

title	An Agent-Based System for Capturing and Indexing Software Design Meetings
source	Gero JS and Brazier FMT (eds) (2002) Agents in Design 2002. Key Centre of Design Computing and Cognition, University of Sydney, pp. 203-218
summary	We present an agent-based system for capturing and indexing software design meetings. During these meetings, designers design object-oriented software tools, including new agent-based technologies for the Intelligent Room, by sketching UML-type designs on a white-board. To capture the design meeting history, the Design Meeting Agent requests available audio, video, and screen capture services from the environment and uses them to capture the entire design meeting. However, finding a particular moment of the design history video and audio records can be cumbersome without a proper indexing scheme. To detect, index, and timestamp significant events in the design process, the Tahuti Agent, also started by the Design Meeting Agent, records, recognizes, and understands the UML-type sketches drawn during the meeting. These timestamps can be mapped to particular moments in the captured video and audio, aiding in the retrieval of the captured information. Metaglue, a multiagent system, provides the computational glue necessary to bind the distributed components of the system together. It also provides necessary tools for seamless multi-modal interaction between the varied agents and the users.

title	Evaluación de Participación e Interacción en LMS MOODLE [Assessment of Participation and Interaction in LMS MOODLE]
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008, pp. 164-167.
summary	Learning Management Systems (LMS) embody spaces that combine Virtual Classrooms, learning communities, repositories of educational resources and communication devices. The use by faculty members and students, in a campus containing the schools of Architecture, Design and Geography, of Open Source LMS MOODLE, during the years 2005-2006, was assessed. An analysis of the Digital Vestiges, the metadata in the logs database, distinguished between the levels of informative and communicational interaction. The results draw attention to a trend, similar to previous measurements in Latin America, of more use of ICT educational resources for informational purposes than communicational interactions between teachers and students.

title	Ludi: A Concurrent Physical and Digital Modeling Environment
doi	https://doi.org/10.52842/conf.caadria.2018.1.515
source	T. Fukuda, W. Huang, P. Janssen, K. Crolla, S. Alhadidi (eds.), Learning, Adapting and Prototyping - Proceedings of the 23rd CAADRIA Conference - Volume 1, Tsinghua University, Beijing, China, 17-19 May 2018, pp. 515-523
summary	This paper explores the potential of a concurrent physical and digital modeling environment. We describe a prototype for a novel design modeling interface where users can take advantage of the affordances of both physical and digital modeling environments, and work back and forth between the two. Using Processing, along with the Kinect depth sensor, the system uses depth data read from a physical modeling space to produce an enhanced digital representation in real time. Users can design by moving and stacking wooden blocks in a physical space, which is represented (and enhanced) digitally as a "voxel space," which can in turn be edited digitally. The result is a proof-of-concept concurrent physical and digital modeling environment combining design affordances specific to each media: the physical space offers tactile and embodied forms of design inter-action, and the digital space offers parametric editing capabilities, along with the capacity to view the modeling space from different perspectives, and perform basic analyses on designs. Following a brief review of experimental computational and tangible interaction design interfaces, the paper discusses the system's implementation, its limitations, and future steps.

title	Envelope tesselation with stochastic rotation of 4-fold penttiles
doi	https://doi.org/10.52842/conf.caadria.2012.253
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 253–262
summary	The challenge of developing adaptive, responsive low-energy architecture requires new knowledge about the complex and dynamic interaction between envelope architecture and optimisation between competing environmental performance metrics. Advances in modelling the geometry of building envelopes and control technologies for adaptive buildings now permit the sophisticated evaluation of alternative envelope configurations for a set of performance criteria. This paper reports on a study of the parametric control of a building envelope based on moveable façade components, acting as a shading device to reduce thermal gain within the building. This is investigated using a novel pentagonal tiling strategy considering the component design, tessellation and control methods.

title	A Survey of 3D Interaction Techniques
source	Computer Graphics Forum, 165
summary	Recent gains in the performance of 3D graphics hardware and rendering systems have not been matched by a corresponding improvement in our knowledge of how to interact with the virtual environments we create; therefore there is a need to examine these further if we are to improve the overall quality of our interactive 3D systems. This paper examines some of the interaction techniques which have been developed for object manipulation, navigation and application control in 3D virtual environments. The use of both mouse-based techniques and 3D input devices is considered, along with the role of feedback and some aspects of tools and widgets.

title	Computer Aided Cognition and Creativity: A Three Year Monitoring Exercise
doi	https://doi.org/10.52842/conf.ecaade.2012.2.233

summary	This paper tracked the progress of 24 students who were ‘intensive’ users of CAD and 26 ‘occasional’ CAD users over a 3 year period. At the end of each year, student attitudes toward creativity dimensions were monitored, using questionnaires and semi-structured interviews. The collected data was analyzed with the Statistical Package for Social Sciences (SPSS). The statistical tests displayed a signifi cant difference between both groups in terms of ideation fl uency and ideation fl exibility (P<0.05). Within the intensive CAD group the tests also yielded signifi cant differences between years (P<0.05). Ideation fl uency correlated positively with years of study and was infl uenced by CAD and design maturity both as a ‘main effect’ and as an ‘interaction’. The cognitive preference for complexity as a design trait in the intensive group also correlated with the increased complexity of the digital tools used; preference for low complexity correlated with the use of direct CAD tools whereas higher levels of complexity correlated with the deployment of parametric and generative tools.

title	Tools as Design Instruments: Computers and Cognition?
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 1-12.
summary	This inquiry researches the impact of digital tools on the design process and empirically tests the association between computer aided design tools and each of cognition and creativity in architectural practice. The paper analyses the ‘design-tool’ relationship and reviews research in the field of computers as an instrument for creativity, examines their deductions and conducts a case study. Statistical analysis of the case study suggests that three measures of creativity correlated significantly with the length of time a subject spends using the computer in design: rho=0.487, P<0.05 for elaboration of design ideas; rho=0.605, P<0.05, for volume of ideas; rho=0.687, P<0.05, for ideation variety. Also, the length of designer-computer interaction seems to scaffold various forms of design reasoning and help cognition: rho=0.591, P<0.05. The study found little evidence to support the notion that computers prevent other forms of knowing.

title	Visual Simulation as a Tool for Planning Education - Computer Aided Participation Support
doi	https://doi.org/10.52842/conf.ecaade.2004.500
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 500-507
summary	Contemporary computer techniques offer many new opportunities to engage citizens into the planning process. There are new possibilities of interaction, introducing an observer into the “game”. The research project presented in the paper assumes the use of a visual 3D language which consists of a series of schematic types of buildings. They form a language which is easy to understand both by professionals and by laymen. Understanding is the very first step towards getting convinced by the ideas presented. The next step is interaction - the user’s action induces the response of the system. The solution proposed by the user meets an evaluation from the part of the system which evokes the user’s interest - in the case presented here the evaluation introduces the simulation of future state of the site. The problem posed is to find out the best way to convince people that some places are less or more suitable for settlement, depending on the media present there, distance from the urban areas and the environment protection. The attempt to create a tool which could be helpful in an educational process is described in the paper. The idea is to prepare a form of a master plan record which uses the visual 3D language and may be accessed via World Wide Web pages. The paper formulates the assessments for the software described above and examines the possibility to create an application. The trial to prepare a web based service using the flash and shockwave technology is presented.

summary	This paper outlines two major aspects of virtual environments for architectural design. On the one hand it focusses on how to use virtual reality as an extended tool to generate spatial design by building up and interacting with a three-dimensional digital model. On the other hand it describes - based on a case study - the relation between perception, interaction and immersion in virtual environments. Both approaches can be interconnected to a continues design process, that allows the designer to create, manipulate, visualize and decide on spatial concepts in a holistic three-dimensional simulation.

summary	Next to the possibilities of digital form-finding strategies, parametric design and computational visualization techniques, which lead to an increasing virtualization of our society - rapid technologies allow today for the direct translation of the digital model into the physical world. As a result of this process the experience of digital realities, driven by virtual environment gets an interesting shift back to the physical world. Against this background the paper points out that it is a question of design to define contemporary and intended matters, processes and strategies of interaction, in other words: to inform the design.

summary	The fourth Industrial Revolution is characterised by the computational fusion of physical, digital and biological systems. Increasing information in terms of size, speed and scope exponentially. This fusion requires improved, if not new, tools and methods to deal with complexity and information processing. By opening Generative Systems to interact with the context, we believe that they can develop solutions that are more adequate for our time. This research began with a literature review about generative systems and their application to solve problems. We then selected the tools, Cellular Automata, L-Systems, Genetic Algorithms and Shape Grammar, and thought about how to translate these original mathematical tools to specific design situations. We tested the application of these tools and methods in a workshop, implementing recursive loops to open these techniques to interference. Analysing the empirical results made us revise our design thinking, relying on the study of complexity to understand how these techniques can be more context-aware, so we can make design evolve. Finally, we present a comparative framework analyses that interlaces techniques and methods, so in the future we can merge physical, digital and biological information.

title	Design support via simulation of building and plant thermal interaction
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Design decision support related to building energy consumption and/or indoor climate should be based on an integral approach to the environment, the building, heating, ventilating and air-conditioning (HVAC) system, and the occupants. The tools to achieve this are now available in the form of computer simulation systems which treat the building and plant as an integrated dynamic system. Although its potentials reach beyond the area of Computer Aided Building Design, the paper describes building and plant energy simulation within the context of CABD, design decision support and design evaluation. Currently, computer simulation is only used indirectly as a design decision support mechanism; that is, its power is not delivered very efficiently to the design profession. This paper suggests some future research directions. These are aimed at providing a mechanism to overcome this problem by developing an intelligent front end' which bridges the gap between sophisticated computer simulation tools and the design profession.

title	On the Thermal Interaction of Building Structure and Heating and Ventilating System
source	Eindhoven University of Technology
summary	In this dissertation, developments in the field of building performance evaluation tools are described. The subject of these tools is the thermal interaction of building structure and heating and ventilating system. The employed technique is computer simulation of the integrated, dynamic system comprising the occupants, the building and its heating and ventilating system. With respect to buildings and the heating and ventilating systems which service them, the practical objective is ensuring thermal comfort while using an optimum amount of fuel. While defining the optimum had to be left for other workers, the issue of thermal comfort is addressed here. The conventional theory of thermal comfort in conditions characteristic for dwellings and offices assumes steady-state conditions. Yet thermal conditions in buildings are seldom steady, due to the thermal interaction between building structure, climate, occupancy, and auxiliary systems. A literature rewiew is presented regarding work on thermal comfort specifically undertaken to examine what fluctuations in indoor climate may be acceptable. From the results, assessment criteria are defined. Although its potentials reach beyond the area of Computer Aided Building Design, a description is given of building and plant energy simulation within the context of the CABD field of technology. Following an account of the present state-of-the-art, the choice for starting from an existing energy simulation environment (ESPR) is justified. The main development areas of this software platform - within the present context - are identified as: fluid flow simulation, plant simulation, and their integration with the building side of the overall problem domain. In the field of fluid flow simulation, a fluid flow network simulation module is described. The module is based on the mass balance approach, and may be operated either in standalone mode or from within the integrated building and plant energy simulation system. The program is capable of predicting pressures and mass flows in a user-defined building / plant network comprising nodes (ie building zones, plant components, etc) and connections (ie air leakages, fans, pipes, ducts, etc), when subjected to flow control (eg thermostatic valves) and / or to transient boundary conditions (eg due to wind). The modelling and simulation techniques employed to predict the dynamic behaviour of the heating and ventilating system, are elaborated. The simultaneous approach of the plant and its associated control is described. The present work involved extensions to the ESPR energy simulation environment with respect to robustness of the program, and with respect to additional plant simulation features, supported plant component models and control features. The coupling of fluid flow, plant side energy and mass, and building side energy simulation into one integrated program is described. It is this "modular-simultaneous" technique for the simulation of combined heat and fluid flow in a building / plant context, which enables an integral approach of the thermal interaction of building structure and heating and ventilating system. A multi stage verification and validation methodology is described, and its applicability to the present work is demonstrated by a number of examples addressing each successive step of the methodology. A number of imaginary and real world case studies are described to demonstrate application of the present work both in a modelling orientated context and in a building engineering context. Then the general conclusions of the present work are summarized. Next and finally, there are recommendations towards possible future work in the areas of: theory, user interface, software structure, application, and technology transfer.

summary	This project suggests a specific study of design using domotics, including its skins and limits, and its equipment. We recognize the capacity of domotics to optimize the functions of diverse architectural typologies by systematizing already - existing technologies. We present an example of design that contemplates the inclusion of domotics in transportable typologies using innovative materials to explore the designs and proposals of haptic technology; this increases the number of traditional interfaces so users—including children and individuals with different disabilities—can increasingly interact with architecture and technology.

summary	This paper presents the research and development of a concrete micro-architecture proposal, based on a useful design for an interstitial urban space.The typology is a hydration station in the doors of an urban park, the park Sarmiento of the city of Córdoba where many gymnasts converge. The space with inmotic technology is resilient, able to mutate to be more comfortable, and is able to offer water with use control to ration in case of urban emergency. Working with domotics allows us to optimize the management of resources and therefore increase the efficiency of the systems of use and control.
