title	Expert System for Generation and Evaluation in Architectural Design
source	Technion, Faculty of Architecture and Town Planing, Haifa
summary	The research field, focuses on a new research area of Knowledge Based Systems for Architectural Design. The research deals with concepts and tools emerging from Artificial Intelligence, Knowledge Based Systems and Expert Systems. The research is involved with the construction of a theoretical basis for the development of approaches and methods for the representation and control of design knowledge as a reasoning process. Key questions which attempt to reconsider representation and control in design are formulated. The following questions serve as a research framework out of which new approaches, methods and tools were developed. (1.)What are the existing ideas, methods and tools in Expert Systems? (2.) What are the performance characteristics of Expert Systems in Architectural Design ? (3.) What are the desired operative characteristics and interactions for Expert Systems in design ? (4.) How is it possible to formulate and apply the diverse forms of Architectural Knowledge in Expert Systems for design? (5.) What are the problems of implementation in the development of Expert Systems for design ? The state of the art in knowledge based systems is surveyed, while emphasizing the differences between conventional systems and knowledge based systems. Representation and control methods and the components of expert systems are reviewed. Expert systems for diagnosis, interpretation, planning and design are analysed with respect to their performance characteristics. Techniques and technologies of existing tools are defined. An expert system for the generation and evaluation of ill defined architectural design problems is develped. A formalization of the concept of 'design interpretation' is proposed and developed. It is applied in the process of defining and classifying the performance characteristics of expert systems for design. This concept is based upon two sets of reasoning processes: those which enable a mapping between design requirements and solution descriptions in the generation stage of design and those between solution descriptions and performance evaluation in the evaluation stage of design. On the basis of the formalization of this concept, an expert system capable of integrating various modes of performance is proposed and developed. The system functions as a 'design generator', a 'design critic', or a' design critic-generator'. These modes, which integrate generation and evaluation in the same system, operate by employing both forward chaining and backward chaining inference mechanisms. As a result of the examination of desired forms of interactions, a new approach for dual direction interpretation between graphic and verbal modes is developed. This approach reflects the importance of both graphical and verbal expression in design. The approach is based upon a simultaneous mapping between symbolic-verbal interpretation and graphic interpretation. The work presents the mapping process through the concept of design interpretation, employing geometrical knowledge, typological knowledge and evaluation knowledge. A tool which provides communication between an expert system and a graphic system was developed and is presented. The importance of such a tool in expert systems for design resides in the provision of free choice to the user for interacting with the system either graphically or verbally during the design process. An additional component in the development of knowledge-based systems for design is related to the important question of knowledge definition and the representational schemata of design knowledge. A new representational scheme for complex architectural knowledge, termed 'The generation and refinement scheme of a design prototype' is proposed and developed. Its operation as part of a total integrated design system is demonstrated. The scheme is based upon the structures of knowledge of design precedents which constitute typical situations and solutions in architectural design. This scheme provides an appropriate representation for the two types of knowledge which operate in a refinement process of a design prototype. Generative knowledge describes the solution space by predefined refinement stages; interpretive knowledge enables their selection. The examination of representational methods for the proposed scheme indicated that employing a single representational method lacked enough generalization and expressive power for the needs of the design knowledge structures. It was found that a way to represent complex structures is through the integration of multiple methods of representation, each one according to the knowledge characteristics. In order to represent the proposed scheme of design knowledge, a unique method was developed which integrates both rules and frames. The method consists of a rules-frames-rules structure for the representation of a design prototype. An approach is developed for the implementation of these concepts in an expert system for design. PRODS: A prototype based expert system shell for design is developed and demonstrated. The system consists of three basic components: a rule-based expert system shell, a frame system, and a knowledge base interface. All system interactions are controlled by the inference engine. It passes control between the rule-base and the frame-base inference engines, and provides communications between the rule-based and frame-based representations. It is suggested that expert system can interface with external CAD systems including graphics, communicating through a central representation. These concepts and developments are demonstrated in two implementations. The PREDIKT system for the preliminary design of the residential kitchen; the PROUST system for the selection and refinement of dwelling types. PREDIKT demonstrates the integration of rules and a graphical-verbal interpreter; in addition, PROUST demonstrates the significance of hybrid representation in the generation and refinement processes. The results and conlusions are summarized. Future research agenda within the field of knowledge-based systems for design is discussed, and potential research areas are defined.

title	Machine Learning for Expert Systems : Motivation and Techniques
source	i-iii, 51 p. : some ill Pittsburgh, PA: Engineering Design Research Center, CMU, June, 1988. EDRC 12-27-88. includes bibliography. First generation expert systems suffer from two major problems: they are brittle and their development is a long, effortful process. Few successful expert systems for real world problems have been demonstrated. In this paper, learning, the key to intelligent behavior and expertise, is described as the answer to both expert systems deficiencies. Machine learning techniques are described, with their applicability to expert systems. A framework to organize machine learning techniques is provided. The description is followed by examples taken from the structural design domain. AI / learning / expert systems / structures / techniques. 37. Requicha, Aristides A. G.

summary	Computational models of solid objects are potentially useful in a variety of scientific and engineering fields, and in particular in the field of design and manufacturing automation for the mechanical industries. In recent years a multitude of modelling systems have been implemented both by research laboratories and commercial vendors, but little attention has been paid to the fundamental theoretical issues in geometric modelling. This has led to severe difficulties in assessing current and proposed systems, and in distinguishing essential capabilities and limitations from user conveniences and efficiency considerations. This paper seeks a sharp mathematical characterization of 'rigid solids' in a manner that is suitable for studies in design and production automation. It draws heavily on established results in modern geometry and topology. Relevant results scattered throughout the mathematical literature are placed in a coherent framework and presented in a form accessible to engineers and computer scientists. A companion paper is devoted to a discussion of representational issues in the context set forth by this paper

summary	This paper will present examples of current practice in the Design Studio course of the BDE, University of Strathclyde. The paper will demonstrate an integrated approach to teaching design, which includes CAD among other visual communication techniques as a means to exploring design concepts and the presentation of complex information as part of the design process. It will indicate how the theoretical dimension is used to direct the student in their areas of independent study. Projects illustrated will include design precedents that have involved students in the review and assessment of landmarks in the history of design. There will be evidence of how students integrate DTP in the presentation of site analysis, research of appropriate design precedents and presentation of their design solutions. CADET underlines the importance of considering design solutions within the context of both our European cultural context and of assessing the environmental impact of design options, for which CAD is eminently suited. As much as a critical method is essential to the development of the design process, a historical perspective and an appreciation of the sophistication of communicative media will inform the analysis of structural form and meaning in a modem urban context. Conscious of the dynamic of social and historical influences in design practice, the student is enabled "to take a critical stand against the dogmatism of the school "(Gadamer, 1988) that inevitably insinuates itself in learning institutions and professional practice.

title	SEED: A Software Environment to Support the Early Phases in Building Design
source	Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary	The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

source	Second International Conference on Computer Aided Architectural Design Futures / ISBN 0-444-42916-6 / Eindhoven (The Netherlands), 20-22 May 1987, 261 p.
summary	The building Industry is Europe's largest single industry employing directly or indirectly 1 in 8 of the working population; yet it is fragmented, ill-organised and unprogressive. Part at least of the cause can be attributed to a failure by the architectural profession to adopt advances in Information Technology - notably Computer Aided Design. The purpose of the series of conferences on CAAD Futures is to chart a route towards a future in which the outcome of current and continuing research and development results in design tools which are acceptable to practioners and which substantially improve the quality of design decision-making and management. The papers which are printed in these proceedings make a significant contribution to our view of the future. Together they cover the range of issues which are the legitimate concern of researchers, developers, vendors, and users of CAAD software; as might be expected, they raise as many questions as they answer and they pose problems as well as reporting progress.

title	Logical Models for Rule-based CAAD
source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 107-116
summary	The aim of this paper is to present the basic results of a theoretic approach to represent architectural individual forms in CAD systems. From the point of view of design methodology and problem solving these descriptions might be conceived' as parts of possible environments satisfying the laws of some design theory in logical sense. This paper describes results in a series of logical studies towards rule and knowledge based systems for design automation. The effective use of programming languages and computers as design aids in architecture presupposes certain capabilities to articulate built environment logically. The use of graphic languages in the description of environmental items e.g. buildings might be theoretically mastered by formal production systems including linguistic, geometric, and spatio-material generation. The combination of the power of formal mechanisms and logical individual calculus offers suitable framework to generate arbitrary e.g. free spatial compositions as types or unique solutions. In this frame it is natural to represent in a coherent way very complex hierarchical parsing of buildings in explicit form as needed in computer implementations. In order to simulate real design work the individual configurations of possible built forms should be designed to satisfy known rules. In the preliminary stage partial solutions to design problems may be discussed in mathematical terms using frameworks like lattices, graphs, or group theoretical considerations of structural, functional, and visual organization of buildings. The capability to produce mathematically sophisticated geometric structures allows us to generalize the approach further. The theoretical design knowhow in architecture can be partly translated in to some logic and represented in a knowledge base. These rules are used as selection criteria for geometric design candidates in the sense of logical model theory and mathematical optimization. The economy of the system can be developed by using suitable conduct mechanisms familiar e.g. from logic programming. The semantics of logic offers a frame to consider computer assisted and formal generation in design. A number of semantic and pragmatic problems, however, remain to be solved. In any case conceptual analyses based on logic are applicable in order to rationally reconstruct architectural goals contributing to the quality of environmental design, which should be the main goal in the development of design systems in near future.

title	The Conceptual Approach to CAD Education
doi	https://doi.org/10.52842/conf.acadia.1988.035
source	Computing in Design Education [ACADIA Conference Proceedings] Ann Arbor (Michigan / USA) 28-30 October 1988, pp. 35-45
summary	Recent research at the Corps of Engineers Construction Engineering Research Laboratory (CERL) investigated embedded computer-based instruction for AutoCAD. The results of this study, which are the focus of this paper, indicated that the only factor which correlated with success in completing the final test was previous experience with another CAD system. Those who knew another CAD system had higher scores and required less than half the time to complete the lessons. Presumably their conceptual knowledge about CAD transferred to the new software environment, even though the Corps' study showed that they were initially biased against learning the new system. Such biased attitudes have been observed when users are asked to learn a second similar software of any kind. Architects who are deeply involved in computer-aided design have stated that one must learn to program the computer to build the conceptual framework for the creative process. We at CERL agree that an understanding of underlying graphics concepts is essential to the designer. Our research shows that giving students the freedom to explore an existing software program can result in the development of conceptual knowledge. Interviews also reveal that students can invent ways to meet individual objectives when "guided discovery" learning is encouraged.

title	Requirements for Developing an Information System for Architecture
source	CAAD futures ‘87 [Conference Proceedings / ISBN 0-444-42916-6] Eindhoven (The Netherlands), 20-22 May 1987, pp. 149-170
summary	This paper discusses possibilities of developing new tools for architectural design. It argues that architects should meet the challenge of information technology and computer-based design techniques. One such attempt has been the first phase of the development of an architectural design information system (ADIS), also an architectural design decision support system. The system should benefit from the developments of the artificial intelligence to enable the architect to have access to information required to carry out design work. In other words: the system functions as a huge on-line electronic library of architecture, containing up-to-date architectural design information, literature, documents, etc. At the same time, the system offers necessary design aids such as computer programs for design process, drawing programs, evaluation programs, cost calculation programs, etc. The system also provides data communication between the architect and members of the design coalition team. This is found to be of vital importance in the architectural design process, because it can enable the architect to fit in changes, brought about in the project by different parties. Furthermore, they will be able, to oversee promptly the consequences of changes or decisions in a comprehensive manner. The system will offer advantages over the more commonly applied microcomputer based CAAD and IGDM (integrated graphics database management) systems, or even larger systems available to an architect. Computer programs as well as hardware change rapidly and become obsolete. Therefore, unrelenting investment pressure to up-date both software and hardware exists. The financial burden of this is heavy, in particular for smaller architectural practices (for instance an architect working for himself or herself and usually with few or no permanent staff). ADIS, as an on-line architectural design aid, is constantly up-dated by its own organisation. This task will be co-ordinated by the ADIS data- base administrator (DBA). The processing possibilities of the system are faster, therefore more complex processing tasks can be handled. Complicated large graphic data files, can be easily retrieved and manipulated by ADIS, a large system. In addition, the cost of an on-line system will be much less than any other system. The system is based on one model of the architectural design process, but will eventually contain a variety of design models, as it develops. The development of the system will be an evolutionary process, making use of its users' feed-back system. ADIS is seen as a step towards full automation of architectural design practices. Apart from being an architectural design support system, ADIS will assist the architect in his/her administrative and organisational activities.

title	The Application of Cognitive Psychology to CAD Input/Output
source	Proceedings of the HCI'88 Conference on People and Computers IV 1988 p.477-488
summary	The design of usable human-computer interfaces is one of the primary goals of the HCI specialist. To date however interest has focussed mainly on office or text based systems such as word processors or databases. Computer aided design (CAD) represents a major challenge to the human factors community to provide suitable input and expertise in an area where the users goals and requirements are cognitively distinct from more typical HCI. The present paper is based on psychological investigations of the engineering domain, involving an experimental comparison of designers using CAD and the more traditional drawing board. By employing protocol analytic techniques it is possible to shed light on the complex problem-solving nature of design and to demonstrate the crucial role of human factors in the development of interfaces which facilitate the designers in their task. A model of the cognition of design is proposed which indicates that available knowledge and guidelines alone are not sufficient to aid CAD developers and the distinct nature of the engineering designer's task merits specific attention.

title	An Evaluation of Programming Languages and Language Features for Engineering Software Development
source	International Journal of Engineering with Computers. Springer-Verlag, 1988. vol. 3: pp. 183-199
summary	Also published as 'Procedural Programming Languages for the Development of CAD and CAE Systems Software,' in the proceedings of ASME International Conference on Computers in Engineering (1987 : New York, NY). The scope of engineering software has increased dramatically in the past decade. In its early years, most engineering applications were concerned solely with solving difficult numerical problems, and little attention was paid to man- machine interaction, to data management, or to integrated software systems. Now computers solve a much wider variety of problems, including those in which numerical computations are less predominant. In addition, completely new areas of engineering applications such as artificial intelligence have recently emerged. It is well recognized that the particular programming language used to develop an engineering application can dramatically affect the development cost, operating cost. reliability, and usability of the resulting software. With the increase in the variety, functionality, and complexity of engineering software, with its more widespread use, and with its increasing importance, more attention must be paid to programming language suitability so that rational decisions regarding language selection may be made. It is important that professional engineers be aware of the issues addressed in this paper, for it is they who must design, acquire, and use applications software, as well as occasionally develop or manage its development. This paper addresses the need for engineers to possess a working knowledge of the fundamentals of computer programming languages. In pursuit of this, the paper briefly reviews the history of four well known programming languages. It then attempts to identify and to look critically at the attributes of programming languages that significantly affect the production of engineering software. The four procedural programming languages chosen for review are those intended for scientific and general purpose programming, FORTRAN 77, C, Pascal, and Modula-2. These languages are compared and some general observations are made. As it is felt important that professional engineers should be able to make informed decisions about programming language selection, the emphasis throughout this paper is on a methodology of evaluation of programming languages. Choosing an appropriate language can be a complex task and many factors must be considered. Consequently, fundamentals are stressed

summary	Research into the various forms and processes of creativity has been a topic of great interest in the design field for many years. Part of the view is personality, and part of the answer is behavioural. Creativity is also explained through the identity of social values and the whole creative process. This paper proposes to use the interacting creativity model of Csikszentmihalyi as the basic structure, to establish the major criteria of testing creativity in the digital era. This paper demonstrates two facts: first, it confirms that creativity in architecture is truly valuable in the digital age; second, it proves that in the digital era, individuals, cultures and societies are all under the impact of digital technologies, a fact which transforms the model of interacting creativity proposed by Csikszentmihalyi in 1988 into a new model of digital interacting creativity.

title	A Conceptual Framework for Computing in Architectural Design
source	Pennsylvania State University
summary	A brief historical overview of architectural design reveals that there has been a slow development in the conceptualization of the scope of architectural design. Advancing our understanding of the architectural design process reveals new directions for computing in architectural design. This study proposes a conceptual framework for an integrated computing environment. Design disciplines have embarked on a rigorous search for theoretical perspectives and methods that encompass a comprehensive view of architecture. Architectural design has been seen as a sequential process similar to that of industrial design. Attempts to formalize this process based on industrial design methods solved only a fraction of the overall integration problem. The resultant models are inadequate to deal with the complexity of architectural design. Emerging social problem-solving paradigms seek to construct a cognitive psychology of problem solving and have a direct relevance to architectural design. These problem-solving activities include structured, semi-structured, and ill-defined problems, which are included to varying degrees in each problem situation across a continuum of difficulty. Problem solving in architectural design involves the determination of certain objectives and also whether or not it is possible to accomplish them. Developments in computing in architecture have paralleled developments in architectural methodologies. The application of computing in architectural design has predominantly focused only on sequential process, optimum solutions, and quantifiable tasks of the design process. Qualitative, generative, tasks of architectural design were dealt with through the introduction of paradigms from linguistics and knowledge-based systems borrowed from engineering applications. Although the application of such paradigms resulted in some success, this reductionist approach to computing in architecture fragmented its integration into the design process. What is required, therefore, is a unified approach to computing in architecture based on a holistic view of the architectural design process. The model proposed in this study provides such a conceptual framework. This model shifts the focus from product to process and views the design problem as a goal-oriented problem-solving activity that allows a design team to identify strategies and methodologies in the quest for design solutions.

title	A history and application of visual simulation in which perceptual behaviour movement is measured.
source	Architectural and Urban Simulation Techniques in Research and Education [3rd EAEA-Conference Proceedings]
summary	For our research on perception and judgment, we have developed a new visual simulation system based on the previous system. Here, we report on the development history of our system and on the current research employing it. In 1975, the first visual simulation system was introduced, witch comprised a fiberscope and small-scale models. By manipulating the fiberscope's handles, the subject was able to view the models at eye level. When the pen-size CCD TV camera came out, we immediately embraced it, incorporating it into a computer controlled visual simulation system in 1988. It comprises four elements: operation input, drive control, model shooting, and presentation. This system was easy to operate, and the subject gained an omnidirectional, eye-level image as though walking through the model. In 1995, we began developing a new visual system. We wanted to relate the scale model image directly to perceptual behavior, to make natural background images, and to record human feelings in a non-verbal method. Restructuring the above four elements to meet our equirements and adding two more (background shooting and emotion spectrum analysis), we inally completed the new simulation system in 1996. We are employing this system in streetscape research. Using the emotion spectrum system, we are able to record brain waves. Quantifying the visual effects through these waves, we are analyzing the relation between visual effects and physical elements. Thus, we are presented with a new aspect to study: the relationship between brain waves and changes in the physical environment. We will be studying the relation of brain waves in our sequential analysis of the streetscape.

summary	Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

summary	Application of commercial computer aided design systems to schematic design in a studio setting in a professionally oriented university provides the opportunity for observation of extensive use of CAD by designers with little or no orientation toward computing. Within a framework of studios intended to contrast media and highlight the issue of design representation, the most encouraging applications of computing have involved dynamic visual design representation. This paper presents a case study of three studios at the University of Texas at Austin together with commentary on the place of computing in this essentially artistic environment. It presents, in slide form, a body of aesthetically oriented CAD work which signals the spread of computer aided design out of the hands of researchers and into mainstream architectural design, where development of the visual and dynamic aspects of the medium may prove to be primary routes to improvement of itS power and acceptance. Much like a first design project, this paper then presents a lot of observations without yet much rigorous development of any one. It asks implicitly whether application of software constitutes research.

title	Natural Language Interface for CAAD System

summary	This work explores issues involved in the development of a natural interface for man-machine dialogue in architectural design processes. A hand-touch on an interactive surface is suggested as the best natural-language interface for architectural CAD systems. To allow the development of a rich range of hand-touch natural-language for communicating information and commands to the computer, it is proposed to develop a new type of a touch-panel, for which a set of specifications is presented. A conceptual design of an architectural workstation, having the described touch-panel, is presented. This workstation is characterized by the integration of the entire range of control and communication facilities required for any architectural task into a single interactive unit. The conceptual model for this workstation is the standard size drawing board, on which the architect is accustomed to spread documents, drawings, books and tools, shuffle them around and interchange them freely by using the natural-language interface developed in this work. The potential of the suggested hand-touch natural-language and the proposed workstation are demonstrated by a case-study.

title	Automation of Drafting and Building Modelling – Historical Review of Commercial Development since the Seventies
source	CIB-W78 Conference, Lund
summary	The present day GDS system has its roots in BDS, started in 1970, BDS was a 3D data-centered system for design, analysis and documentation of system-built buildings. GDS started as a 2D drafting system, and proved more effective and marketable. Specialized applications and 3D capabilities were added gradually. Current interest is in simplifying the software, especially its user interface.

title	A Cognitively Based Methodology for Evaluating Human Performance in the Computer-Aided Design Task Domain
source	Behaviour and Information Technology 1988 v.7 n.4 p.373-397
summary	This article describes a methodology for evaluating human performance in the computer aided design (CAD) task environment. The methodology is based primarily on cognitive theoretic frameworks that are consistent with processes presumed to underlie human design activities. The motivation for its development stems from rapid software and hardware advances in CAD systems and our relative lack of understanding of how these enhancements affect human design performance for (1) fundamentally different types of tasks and (2) different levels of complexity for a particular task. This methodology is currently being applied to computer aided architectural design, an area where artificial intelligence (AI), enhanced geometric modelling and other system features are being debated in terms of their usefulness in aiding the human's design activities.

title	Comparative Evaluation of Four Daylighting Software Programs
source	1998 ACEEE Summer Study on Energy Efficiency in Buildings Proceedings. American Council for an Energy-Efficient Economy
summary	By the mid-1980's, a number of software packages were under development to predict daylighting performance in buildings, in particular illumination levels in daylighted spaces. An evaluation in 1988 by Ubbelohde et al. demonstrated that none of the software then available was capable of predicting the simplest of real daylighting designs. In the last ten years computer capabilities have evolved rapidly and we have four major packages widely available in the United States. This paper presents a comparative evaluation from the perspective of building and daylighting design practice. A contemporary building completed in 1993 was used as a base case for evaluation. We present the results from field measurements, software predictions and physical modeling as a basis for discussing the capabilities of the software packages in architectural design practice. We found the current software packages far more powerful and nuanced in their ability to predict daylight than previously. Some can accurately predict quantitative daylight performance under varying sky conditions and produce handsome and accurate visualizations of the space. The programs differ significantly, however, in their ease of use, modeling basis and the emphasis between quantitative predictions and visualization in the output.

title	Expert Systems in Environmental Psychology
source	JAPS10 conference. 1988. includes bibliography
summary	The knowledge gathered through research in environmental psychology is not optimally used by designers and other people working in applied settings such as politicians and civil servants. In this paper a number of causes and possible improvements of this situation are discussed. Two aspects are highlighted in particular: the structure and the presentation of information. A recent development to present knowledge from environmental psychology is the use of computerized information systems or expert systems. Limitations and possibilities of expert systems in general and for environmental psychology in particular are discussed. The issue is illustrated with parts of an expert system on the design of children's play environments using the pattern language as a structure to present information efficiently and attractively to designers
