title Determining Type, Part, Color, and Time Relationships
source IEEE Computer. IEEE Computer Society, October, 1983. vol. 16: pp. 53-60 : ill. Includes bibliography
summary Several kinds of inference problems arise constantly in question-answering processes, which without special handling can absorb large computational resources. One kind requires determining how two types of things are related, others require determining these or similar relationships among parts of objects, color or times. As people we are equippedÔ h) 0*0*0*°° ÔŒ with certain sensory organs, we have special ways of modeling our perception of color, categorizing and cross-correlating the entities whose localization in space and persistence in time renders them cognitively coherent and of analyzing spatial properties, such as parts structure. To match our cognitive skills AI system will need analogous special methods. The methods described in this paper are designed to supplement a deductive question-answering algorithm that is now operational. The algorithm draws on a base of logical propositions organized as semantic net

title A digital Procedure of Building Construction: A practical project
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title Before Programming : On Teaching Introductory Computing
source 1983? 10 p. includes bibliography
summary In comparison with most other human intellectual activities, computing is in its infancy despite the progress we seem to have made in such a short time. Consequently, there has been insufficient time for the evolution of 'best ways' to transmit computing concepts and skills. It is therefore prudent to look to more mature disciplines for some guidelines on effective ways to introduce computing to beginners. In this respect the discipline of teaching people to read and write in a natural language is highly relevant. A fundamental characteristic of this latter discipline is that a substantial amount of time is devoted to teaching people to read long before they are asked to write stories, essays, etc. In teaching computing people seem to have overlooked or neglected what corresponds to the reading stage in the process of learning to read and write. In the discussion which follows the author looks at ways of economically giving students the 'computer-reading experience' and preparing them for the more difficult tasks of algorithm design and computer problem-solving

title Smalltalk-80: The language and its implementation
source New York, NY: Addison Wesley Co
summary Smalltalk-80 is the classic standard Smalltalk language as described in Smalltalk-80: The Language and Its Implementation by Goldberg and Robson. This book is commonly called "the Blue Book". Squeak implements the dialect of Smalltalk described in this book, but has a different implementation. Overview of the Smalltalk Language Smalltalk is a general purpose, high level programming language. It was the first original "pure" object oriented language, but not the first to use the object oriented concept, which is credited to Simula 67. The explosive growth of Object Oriented Programming (OOP) technologies began in the early 1980's, with Smalltalk's introduction. Behind it was the idea that the individual human user should be the most important component of any computing system, and that programming should be a natural extension of thinking, and also a dynamic and evolutionary process consistent with the model of human learning activity. In Smalltalk, these ideas are embodied in a framework for human-computer communication. In a sense, Smalltalk is yet another language like C and Pascal, and programs can be written in Smalltalk that have the look and feel of such conventional languages. The difference lies * in the amount of code that can be reduced, * less cryptic syntax, * and code that is easier to handle for application maintenance and enhancement. But Smalltalk's most powerful feature is easy code reuse. Smalltalk makes reuse of programs, routines, and subroutines (methods) far easier. Though procedural languages allow reuse too, it is harder to do, and much easier to cheat. It is no surprise that Smalltalk is relatively easy to learn, mainly due to its simple syntax and semantics, as well as few concepts. Objects, classes, messages, and methods form the basis of programming in Smalltalk. The general methodology to use Smalltalk The notion of human-computer interface also results in Smalltalk promoting the development of safer systems. Errors in Smalltalk may be viewed as objects telling users that confusion exists as to how to perform a desired function.

summary The history of computers in architectural design is very short; only a few decades; when compared to the development of methods in practical design (Gero 1983). However, the development of the user interfaces has been very fast. According to the practical observations of over one hundred architects, user interfaces are at present inflexible in sketching, although computers can make drafts and the creation of alternatives quicker and more effective in the final stages of designing (Haapasalo 1997). Based on our research in the field of practical design we would wish to stimulate a wider debate about the theory of design. More profound perusal compels us to examine human modes, pre-eminently different levels of thinking and manners of inference. What is the meaning of subconscious and conscious thinking in design? What is the role of intuition in practical design? Do the computer aided design programs apply to creative architectural sketching? To answer such questions, distinct, profound and broad understanding from different disciplines is required. Even then, in spite of such specialist knowledge we cannot hope to unambiguously and definitively answer such questions.

title Using Formal Specifications in the Design of a Human-Computer Interface
source Communications of the ACM April, 1983. vol. 26: pp. 259-264 : diagrams. includes bibliography.
summary Formal specification techniques are valuable in software development because they permit a designer to describe the external behavior of a system precisely without specifying its internal implementation. Although formal specifications have been applied to many areas of software systems, they have not been widely used for specifying user interfaces. In the Military Message System project at the Naval Research Laboratory, the user interfaces as well as the other components of a family of message systems are specified formally, and prototypes are then implemented from the specifications. This paper illustrates the specification of the user interface module for the family of message systems. It then surveys specification techniques that can be applied to human-computer interfaces and divides the techniques into two categories: those based on state transition diagrams and those based on BNF. Examples of both types of specifications are given. Specification notations based on state transition diagrams are preferable to those based on BNF because the former capture the surface structure of the user interface more perspicuously. In either notation, high-level abstraction for describing the semantics of the user interface is needed, and an application-specific one is used here

summary The main interest of the organisation is to improve the design, teaching. The design remains the core of the professional education, while computer science can support a better understanding of the design methods. Computers should amplify the human capabilities like engines allowed to carry higher forces, radio and television enabled communication over larger distances and computers today should aid the human intellectual activities, to gain a better insight in design methodology, to investigate the design process.Design research should study more extensively how buildings behave, the integration and interaction of different disciplines which contribute to the optimization of a design and the design criteria. Computers could increase the possibility to satisfy building regulations, to access and update information, to model the design process and to understand how decisions affect the building quality (functional and economical as well as formal aspects). More effort and money should be spent on this research. The organisation has been sponsored by the EEC for bringing CAAD (Computer Aided Architectural Design) educational material at the disposal of the design teachers. The Helsinki conference is the third European meeting (after Delft 1982 and Brussels 1983) which concentrates on information and experience exchange in CAAD-education and looks for common interests and collaboration. A specific joint study program works on typical audiovisual material and lecture notes, which will be updated according to teacher's needs. A demand has been done to implement an integrated CAAD package. eCAADe focuses to integrate computer approaches across country boundaries as well as across disciplinary boundaries, as to reach a higher quality of the design education.

source T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary A computer-based design critiquing system analyzes a proposed solution and offers critiques (Robbins 1998). Critiques help designers identify problems as well as opportunities to improve their designs. Compared with human critics, today’s computer-based critiquing systems deliver feedback in quite restricted manner. Most systems provide only negative evaluations in text; whereas studio teachers critique by interpreting the student’s design, introducing new ideas, demonstrating and giving examples, and offering evaluations (Bailey 2004; Uluoglu 2000) using speech, writing, and drawing to communicate (Anthony 1991; Schön 1983). This article presents a computer-based critiquing system, Flat-pack Furniture Design Critic (FFDC). This system supports multiple delivery types and modalities, adapting the typical system architecture of constraint-based intelligent tutors (Mitrovic et al. 2007).

summary UNIGRAFIX is a three-dimensional graphics modeling environment that runs under the UNIX operating system. It comprises a terse, human-readable descriptive language that allows scene files of complex objects to be created with little overhead. These scenes can be used as input to a set of UNIGRAFIX programs which can be run either as separate functional units, or from within the interactive UNIGRAFIX environment. Programs are available to transform and illuminate the scene descriptions and to display them in a variety of styles on various output devices. The built-in hidden-face and hidden-line elimination routines use a scan- line algorithm which makes strong use of scan-line coherence as well as object coherence.

summary The research is based on the theory of Space syntax (Hillier and Hanson, 1983). Just as the backbone is essential to compose the human body, two sorts of backbones of the outer spatial configuration of campus are proposed and defined in this thesis. The first is syntactically abstract, which is constituted with the axial lines to represent the relations between the buildings located in campus, and to characterize the essential spatial configuration of campus. The second is a road network which could be represented as a realistic backbone for human activities, and through which human get personal impression and knowledge of outer space of campus. Based on the concept of the backbone, several spatial patterns of campuses are explored and extracted, and the relationships with the spatial cognition and comprehension are quantitatively evaluated.

summary The paper describes an application of CAAD techniques by Final Year architecture students using the computer program AIR-Q to dynamically simulate the emergency evacuation of people from a multi-storey department store. This is presented in the context of a fire emergency and reference made to the local Building Regulations which govern the size and location of fire exits. It is suggested that the technique not only provides students and designers with an easily assimilated understanding of the consequences of design decisions but also allows alternative design solutions to be quickly compared in a search for the optional design strategy. The exercise also demonstrates, to the students, the logic behind the rules contained in the Fire Regulations while demonstrating possible weaknesses and inadequacies of the empirical approach that these regulations are constrained to adopt.

summary Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.

summary GABLE CAD SYSTEMS comprise a suite of integrated sub-systems, one of which is OMS. The use of OMS in the development of a building design enables three dimensional graphical modelling of objects associated with buildings. Thus furniture, fittings and fixtures may be located within any room in a building or outside a building or in relation to other groups of objects unrelated to a building. Once located, objects and building may be seen in 2D plan and elevation/section projection or 3D projection (perspectives, axonometrics, isometrics, etc.). In this way furniture, people, cars, trees,landscape objects may all be modelled and graphically represented in addition to the modelling capabilities enabled using GABLE BMS (Building Modelling System). These graphically represented 2D and 3D views of objects can then be passed into GABLE IDS for further embellishment, annotation or dimensioning to produce detailed working drawings.

title Gaming Simulation: A Communication Tool for Architects and Designers
source University of Michigan
summary In today's technological society, people spend more and more time in built environments that they have little or no control in shaping. There is also a large gap in communication between designers of the built environment and non-designers. The language that non-designers use to communicate specific spatial needs, whether aesthetic or functional, is different from the formal language that designers use to communicate these issues with each other. Gaming simulation, as a communication tool, has a number Note of characteristics that make it useful for improving communication and increasing participation among designers and non-designers. In this study, a method of teaching the design of gaming simulation to designers of the built environment is developed. This method includes a Game Design Index or cataloging system of gaming tehniques, within the context of a game design process. A questionnaire was used to interview the designers of the most current physical design games about the gaming techniques in their games. Their answers were organized into the Game Design Index and set within the context of a process for designing a game. This process was tested by teaching a course to graduate students in Urban Planning and Architecture. Further testing was done by holding a game design workshop for professional architects. The findings indicate that it is possible to analyze existing games for their gaming techniques and to index them in an organized way. It is also possible to add this index to an existing game design process. By using this process, graduate students were able to design gaming simulations of high quality, although professionals who attended a day-and-a-half workshop, were not so successful. This latter problem was primarily the result of the complexity of the task and the time constraint imposed. This dissertation describes the game design process that was used to teach neophytes to design games as well as the Game Design Indexes for ten existing games. A comprehensive review of games concerned with physical design is included

It provides a fundamentally different means of representing buildings than do traditional data structures and databases. A prototypical knowledge engineering reasoning system which reasons about topological relationships, geometric entities and attributes of buildings is described. It is applied in the analysis of an existing small hotel. Using knowledge engineering we can expect future CAAD system to be different to the one with which we have become familiar

source Electronic Computation Conference Proceedings (8th : 1983 : Houston, TX). American Society of Civil Engineers, pp. 559-571. CADLINE has abstract only
summary This paper proposes a database schema that supports structural engineering design of buildings. An evaluation and comparison of hierarchical, network, and relational databases shows that relational databases are especially suited to a structural engineering design database. The proposed database schema represents the complex relationships between the components of a building-design database. The schema consists of a structural system hierarchy that relates abstract database components to basic building elements. In addition, it combines topology with attributes to achieve an integration that allows the representation of a broad range of common building configurations and structural systems. The user can combine a basic set of constructs to generate either a general or a very detailed description of a structure. The high degree of integration of topology and attributes yields a database that possesses desirable relational characteristics. The database provides efficient access to components based both on their location and on their attribute values. It also allows the user to add, delete, retrieve, and modify database components and values. The versatility and flexibility of the relational model make it a useful tool for managing building engineering data
