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

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.

summary	Didactic and research experience developed at the "Dipartimento di Ingegneria dei Sistemi Edilizi e Territoriali del Politecnico di Milano" in the environment of Computer Aided Architectural Design (CAAD). From the early part of the 1980's, using initially at an experimental level the resources available at the departmental centre of calculation various applications of CAD techniques in the building sector have been effected at DISET (Dipartimento di Ingegneria del Politecnico di Milano). During 1983, after a three year period of experimenting with these systems, it was decided to organise and activate a small computer aided design centre, within the department, the use of which was reserved for dissertation and research students.

summary	While the basic ideas of frame systems are straight forward, complication arise in their design. A design strategy was developed and have been implemented in a representation system called Krypton. Krypton distinguishes between definitional and factual information by using both frame- based and logic-based languages. The result is a system defined in functional not structural terms

title	Spatial reasoning: improving computational efficiency
source	Automation in Construction 9 (4) (2000) pp. 361-367
summary	When spatial data is analysed the result is often very computer intensive: even by the standards of contemporary technologies, the machine power needed is great and the processing times significant. This is particularly so in 3-D and 4-D scenarios. What we describe here is a technique, which tackles this and associated problems. The technique is founded in the idea of quad-tesseral addressing; a technique, which was originally applied to the analysis of atomic structures. It is based on ideas concerning Hierarchical clustering developed in the 1960s and 1970s to improve data access time [G.M. Morton, A computer oriented geodetic database and a new technique on file sequencing, IBM Canada, 1996.], and on atomic isohedral (same shape) tiling strategies developed in the 1970s and 1980s concerned with group theory [B. Grunbaum, G.C. Shephard, Tilings and Patterns, Freeman, New York, 1987.]. The technique was first suggested as a suitable representation for GIS in the early 1980s when the two strands were brought together and a tesseral arithmetic applied [F.C. Holdroyd, The Geometry of Tiling Hierarchies, Ars Combanitoria 16B (1983) 211–244.; S.B.M. Bell, B.M. Diaz, F.C. Holroyd, M.J.J. Jackson, Spatially referenced methods of processing raster and vector data, Image and Vision Computing 1 (4) (1983) 211–220.; Diaz, S.B.M. Bell, Spatial Data Processing Using Tesseral Methods, Natural Environment Research Council, Swindon, 1986.]. Here, we describe how that technique can equally be applied to the analysis of environmental interaction with built forms. The way in which the technique deals with the problems described is first to linearise the three-dimensional (3-D) space being investigated. Then, the reasoning applied to that space is applied within the same environment as the definition of the problem data. We show, with an illustrative example, how the technique can be applied. The problem then remains of how to visualise the results of the analysis so undertaken. We show how this has been accomplished so that the 3-D space and the results are represented in a way which facilitates rapid interpretation of the analysis, which has been carried out.

summary	Knowledge engineering allows for the encoding of both numeric and symbolic knowledge as inferences. 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

title	Composing Letters with a Simulated Listening Typewriter
source	Communications of the ACM. April, 1983. vol. 26: pp. 295-308 : ill. graphs, tables. includes bibliography
summary	With a listening typewriter, what an author says would be automatically recognized and displayed in front of him or her. However, speech recognition is not yet advanced enough to provide people with a reliable listening typewriter. An aim of the authors' experiments was to determine if an imperfect listening typewriter would be useful for composing letters. Participants dictated letters, either in isolated words or in consecutive word speech. They did this with simulations of listening typewriters that recognized either a limited vocabulary (1000 or 5000 words) or an unlimited vocabulary. Results suggest that some versions, even upon first using them, could be at least as good as traditional methods of handwriting and dictating. Isolated word speech with large vocabularies may provide the basis for a useful listening typewriter

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

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

title	LISP - A CAD System Programming Language
source	Journal of Technical Topics in Civil Engineers. April, 1983. vol. 109: pp. 58-72
summary	LISP may currently be the best programming language to use for the development of engineering computer-aided design (CAD) systems. While languages like FORTRAN represent important advances over their predecessors, it may be that a single static programming language will never be completely adequate for engineering programming. What is needed is a language that can evolve in response to changing needs. This paper is concerned with the programming languages that support CAD systems. The choice of such a programming language significantly influences the flavor of the product derived from that language. The language should provide a style of interaction and a programming environment that is a good model for software developers. At the very least, this will lead to a consistency among most programs developed using that language. The language should also help reduce program complexity and permit one to program at the level of application concepts, rather than at the level of memory locations. LISP or LISP-like languages provide perhaps our greatest opportunity for reducing program complexity to manageable proportions. More importantly, the systems are of better quality when they reflect the style provided by LISP; they tend to be more easily tailored to the needs of individual users

source	Proceedings of the International Conference eCAADe [European Computer Aided Architectural Design Education] Brussels (Belgium) 1983, pp. II.10-II.22
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.

title	An Analysis and Algorithm for Polygon Clipping
source	Communications of the ACM November, 1983. vol. 26: pp. 868-877 : ill. includes bibliography.
summary	(This is one of the two standard algorithms for clipping. The other is the Sutherland-Hodgman reentrant algorithm). The process of polygon clipping is analyzed and the understanding gained thereby forms the foundation of a very direct algorithm. Each edge of the input polygon is considered to be a vector and is then extended to be a line of infinite extent. The boundary line segments of the clip window are extended in a similar fashion to become boundary lines. The intersection points of an extended edge with the boundary lines are identified as entry or exit points. It is observed that these entry and exit points can be used to characterize the visibility status of the edge. Not only might the edge have a visible segment, but it can also induce the inclusion in the output polygon of a vertex at a corner of the clip window called a turning vertex. To quantify the visibility conditions, the edge is written in parametric form. The possible contributions (including nil) that can be provided to the output polygon by a particular edge are established. This analysis is then embedded in an algorithm. An arbitrary example input polygon is given and the output of the algorithm is shown. The execution time for this example using this algorithm is measured to be half of what is required by the standard Sutherland-Hodgman reentrant polygon clipping algorithm

title	Delivery Types And Communication Modalities In The Flat-Pack Furniture Design Critic
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).

summary	This paper describes the results of basic studies on procedures for creating solid models of component geometry from two-dimensional orthographic projections. An interactive graphic program was developed to allow the input of three orthographic views of a component geometry by digitizing from a drawing. The views may contain straight lines and circular arcs, solid or dashed. No restrictions are placed on the order or direction of lines and arcs in any view. Using an extension of the Wesley-Markowski procedure, the program constructs a three-dimensional solid model of the object. When the projections are ambiguous, multiple solid models are produced. The solid model may contain planar, cylindrical, conical, spherical and toroidal surfaces. Topological information of the solid model is sotred in a winged edge sturcture. Geometric information is stored as vertex coordinates and surface equations.
