summary	With the public's high consciousness of townscape, a new form of Color Planning incorporating Citizen Participation is necessary. This paper proposes the use of Dynamic Hypertext Mark-up Language (DHTML) in a Web-oriented Interactive Townscape Assessment System. This system consists of two parts, the first part includes tools for Analytic Hierarchical Process (AHP), Magnitude Estimation, Semantic Differential (SD) and Color Semantic Differential (Color SD) method, and the second part includes tools for Interactive Color Planning System (ICPS). Interactive Assessment is possible by the inclusion of JavaScript and Cascading Style Sheet (CSS). Efficiency is improved by client-side operations, data-collection using Common Gateway Interface (CGI) and presentation using Tabular Data Control (TDC). A case study of large-scale resort facility in Aso Region, Kumamoto Prefecture, Japan is undertaken. The result shows efficiency of the system.

summary	Design computing is an interdisciplinary field that centers on the intersection of design, computer science, and cognitive science. These multi-dimensional faces of this new paradigm necessitate a mutual understanding of computing and design as a whole, which are usually conceived as separate stages of computer-mediated design. This paper explores the use of multiple representations in stimulative design computing learning and teaching environment. This paper starts with an overview of computer-mediated collaborative learning, multiple representations and learner-centered design. Then issues related to the methodology in implementing the system are discussed. Agent models and prototype of the above computer-mediated collaborative learning system are constructed. The research is under progress.

summary	Design Computing is an interdisciplinary field that centres on the intersection of design, computer science and linguistics. This multidimensional face of the new paradigm of design computing necessitates a mutual understanding of computing and designs as a whole, which are usually, conceived as separated stages of computed-mediated design. Based on cognitive and computational approach, with the integration of scaffolding strategies and multiple representations, an interactive and real-time design computing learning system is constructed. By interactively manipulating the various attributes, codes, parameters and digital media contents in a distributed system, learners are gradually exposed to the mutual relationship of representational digital multimedia and the underlining programming syntax in a collaborative environment. The author attempted the use of game programming technology in the development of the above system to support design learning and research in understanding design activities. The aim is to identify the design process that if taught well would address the core goals of design education.

title	Body-Borne Assistive Robots for Human-Dependent Precision Construction - The Compensation of Human Imprecision in Navigating 3-Dimensional Space with a Stand-Alone, Adaptive Robotic System
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. 545-554
doi	https://doi.org/10.52842/conf.caadria.2018.1.545
summary	The rapid growth of complex contemporary architecture design, contributed by the advance in parametric CAD/CAM software, is accompanied by challenges in the production process; it demands both highly trained workers and technical equipments. This paper reviews current technologies in robotics-aided construction and wearable computers for generic purposes, and proposes the design of a robotic device for construction guidance. It guides the user, the worker, through the assembly process of precision modular constructions, by providing procedural mechanical or haptic assistance in the 3-dimensional positioning of building components. The device is designed to be wearable, portable, and operable as a completely stand-alone system that requires no external infrastructure. A prototype of the device is tested with a mock-up masonry construction experiment, the result of which is reported in this paper, along with discussion for future improvement and application opportunities within the context of highly developed, condensed Japanese urban environments. A greater objective of this paper is to bridge current studies in Human-Computer Interaction (HCI) and digital fabrication in architecture and promote the potentials of human workers in future construction scenes.

title	Graphic Data Comprehension In Design Thinking
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	There exist several kinds of data qualities when we see a graphic. In such a procedure, we rarely describe all the qualities by language. This is an interesting phenomenon. We are doing something that we understand but we cannot tell when we are thinking or drawing a graphic. A problem like this touches the central point related to the understanding of drawing in design. It is the purpose of this study. A series of experiments is conducted to compare two sets of data: design by drawing and design without drawing. The major result of this experiment is that the type without drawing contains less design contents and is easy to reassemble. The drawing type contains much richer design contents which easily disappeared when reassembled through the descriptions. We believe there exist two major characters of visual data: nameable and unnameable. Nameable data may be designed and communicated without drawing. For the unnameable one, we may proceed when its qualities show out. According to this study, we conclude that the mental representation of visual data is basically prepositional rather than picture-like. But, in design procedures, the picture-like one may appear when the figure comes out of the mental world, with lots of unnameable qualities.

title	Controlling inter-process coordination in a web-based collaborative environment
source	CAADRIA 2001 [Proceedings of the Sixth Conference on Computer Aided Architectural Design Research in Asia / ISBN 1-86487-096-6] Sydney 19-21 April 2001, pp. 113-124
doi	https://doi.org/10.52842/conf.caadria.2001.113
summary	This paper presents a rule-based mechanism for mediating design processes in a web-based collaborative environment. This mechanism is developed based on a logical description of flexible declarative inter-dependency relationships between collaborative design activities. We address design coordination problems by focusing on overlapping problem solving within dynamic workflow. A system prototype is presented to demonstrate our approach. This prototype is part of "DECADE", a long-term project to develop the needed technologies supporting design collaboration.

title	Location of a Point in a Planar Subdivision and its Applications
source	SIAM Journal of Computing. September, 1977. vol. 6: pp. 594-606 : ill. includes bibliography
summary	Given a subdivision of the plane induced by a planar graph with n vertices, in this paper the problem of identifying which region of the subdivision contains a given test points is considered. A search algorithm, called point-location algorithm, which operates on a suitably preprocessed data structure is presented. The search runs in time at most O((log n)2), while the preprocessing task runs in time at most O(n log n) and requires O(n) storage. The methods are quite general, since an arbitrary subdivision can be transformed in time at most O(n log n) into one to which the preprocessing procedure is applicable. This solution of the point location problem yields interesting and efficient solutions of other geometric problems, such as spatial convex inclusion and inclusion in an arbitrary polygon

doi	https://doi.org/10.52842/conf.acadia.2011.x.g8x
summary	To the architect, city zoning ordinances that pertain to site setbacks and building envelope profiles are often viewed as restrictive and introduced late in the design process. Conversely, to the urban planner, building design that is more individual, varied, and/or formally sculptural can be viewed as having a negative impact on the urban fabric. Is there a way to create a healthy dialogue between these seemingly polarizing disciplines with a common language?

title	Context Aware Paper-Based Review Instrument A Tangible User Interface for Architecture Design Review
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 317-327
doi	https://doi.org/10.52842/conf.acadia.2006.317
summary	We describe the design and implementation of a prototype computer-supported collaborative work (CSCW) environment for review of architectural construction documents. This environment utilizes a novel plain-paper tangible interface that supports shared activity such as review of construction documents using an “over the shoulder” computational assistant called CAPRI.Despite the increasing use of computers, work in most architecture firms still largely revolves around paper drawings. Architects structure their work around paper instead of digital representations for reasons of legal liability and tradition, as well as technical limitations. While hardcopy is intuitive, dense, and easy to access, it lacks direct connection to the wide range of design knowledge increasingly available in interactive design environments. This lack is felt most acutely during design review processes, when the designer or reviewer is often called upon to consult and consider holistically a variety of supporting (backing) documents, a task which requires focused attention and a good memory, if errors are to be avoided.Our prototype system enables multiple reviewers to interact equally with a paper construction document using a tangible interface to query detail and backing data from a project knowledge base. We believe this will decrease the reviewer’s cognitive load by bringing design data to them in a contextual and timely way. In doing so, we believe errors will be caught sooner and mistakes reduced.

summary	The existing historic city attracts the attention of architects and educators for its architectural value and history. In addition, many researches on visualisation of historic sites such as world heritage sites are in progress in order to represent the importance of preservation and restoration. New Lanark is the best-preserved example of a cotton-spinning village from the early period of Britain’s industrialisation, and is of international significance in terms of economic, architectural and social history. The village has also been nominated for inclusion in UNESCO’s list of World Heritage Sites. This paper aims to describe development procedure of virtual historic village of New Lanark for educating people about its significant social history and a unique type of building. A multimedia environment is useful for this purpose considering dynamic links among different kinds of resources such as text, images, 3D models and animations. Through this environment people can access from where they are to virtual heritage and navigate 3D space by animation with virtual guidance.

title	The evaluation system for design alternatives in collaborative design
source	Automation in Construction 10 (3) (2001) pp. 295-301
summary	The evaluation of design alternatives is an important phase for supporting design decision and for producing new design concepts, and it is repeatedly processed. To proceed with the design process in standard, the repetition is reduced to minimum, and design must be optimized in limited cost and time. For smooth and fast process, lots of design alternatives are provided within the limit of possibility and they must be evaluated appropriately. It's possible to evaluate design alternatives using various media. This paper describes the characteristics of various media that have been used for evaluation of design alternatives, and propose the evaluation system for design alternatives based on the findings of case studies.

doi	https://doi.org/10.52842/conf.ecaade.1997.x.q2n
summary	The architectural design requires collaboration among various participants, such as architects, clients, engineers in the stages of the design process. The Sasada laboratory has been involved in the various collaborative architectural design projects. The authors found several important issues in the process of those projects. Firstly, the presentation data is composed of different kinds of data such as documents, computer generated still images, movies and 3D objects. The participants involved in those projects need to access these data as necessary. Secondly, it is virtually impossible for all participants to attend at the same time and place. Therefore, computer networked collaborative design work is essential, in particular, for an international project and for a complex architectural design project.

summary	Graduate Institute of Architecture, National Chiao Tung University, Hsinchu 30050, Taiwan The evolution of design media has kept a close relationship with the development of design methods in the history. Nowadays, different computer media have been used in different stages of the design process. It is to believe that computer media have great impact on the design process and methods. The objective of this paper is to realize the design process and methods when designers use computer modeling to tackle an architectural design problem. The methodologies are non- participant observation and retrospection. The findings of this research prove that media does contribute to the changes in design process and methods. Not only does its conclusion help to better understand properties of different media, but also benefit the development of computer media.

summary	Korean traditional structure is constructed as prefabrication jointed in largely characterized by its unique components under the specific rules of assembly and proportion. This point is a double-edges sword. Because, while various shapes and sizes of components based upon an objected-oriented form appear the potential possibility of producing changeable prototypes to build up, these various characters of components and several jointed methods has made difficulties to handle. Accordingly, an automatic 3D modeling algorithm is focused on the methodology of changeable prototypes of Korean Traditional architecture keeping traditional jointed methods with setting various characters of components

summary	This paper describes the color design process of the house in the village. The color design process proposed in this paper constitutes design stages such as color selection, color application, and color design analysis and evaluation. In the color selection step, a method of arranging colors using a color pallet or a color scheme is described. The color application stage includes the process of creating a village color design alternatives by specifying the color information of the hue, value, and saturation based on the BIM model. The color analysis stage is to numerically identify the color design attributes of the generated color design alternatives. The reason for color analysis and evaluation is to produce various design alternatives with the color harmony and improve the quality of the design.

doi	https://doi.org/10.52842/conf.caadria.2019.1.341
summary	This paper presents a visibility analysis for 3D urban environments and its possible applications for urban design. This multi-view visibility analysis tool was generated by 3D isovist in Grasshopper, Rhino. The advantage of this analysis tool is that it can be compared within the measurement area. In addition, setting a visual object different from the existing isovist. The visual object is a landmark of a city space, such as landscape or object. First, the application experimented on the relevance between the calculation time and precision by this analysis tool. Based on the results of this experiment, it applied it to an actual part of an urban space. The multi-view visibility includes confirming the possibility of a comprehensive evaluation on the urban redevelopment and change of the view caused by the building layout plan - by numerical analysis showing the visual characteristics of the area while using 3D isovist theory. The practically applied area is Shinkiba, which is a part of Tokyo's landfill site; and while using the calculated data, multi-view visibility of each plan in the simulation of the visibility map is compared and evaluated.

doi	https://doi.org/10.52842/conf.acadia.2002.279
summary	In this paper, we present a user-friendly and practical method for seamless integration of computergeneratedimages (CG) with real photographs and video. In general, such seamless integration isextremely difficult and requires recovery of real-world information to simulate the same environment forboth CG and real objects. This real-world information includes camera positions and parameters,shapes, material properties, and motion of real objects. Among these, one of the most important islighting.Image-based lighting that is developed to recover illumination information of the real world fromphotographs has recently become popular in computer graphics. In this paper we present a practicalimage-based lighting method that is based on a simple and easily constructable device: a square platewith a cylindrical stick. We have developed a user-guided system to approximately recover illuminationinformation (i.e. orientations, colors, and intensities of light sources) from a photograph of this device.Our approach also helps to recover surface colors of real objects based on reconstructed lightinginformation.
