summary This paper examines the existing commercial and on-going research computer applications for architectural design. It investigates their uses, predictions and limitations; and reviews the teleology, technologies and theories exploited for computerising design. Finally, I will discuss two trends in the developments of CAAD, and present the new directions in CAAD research. This study will be based on understanding the computer's roles in designing, and further on establishing a new theoretical paradigm for mediating a computer system.

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.2005.142
source Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 142-155
summary Intelligent environments are buildings and other settings that can recognize the changing needs of their users and/or the changing nature of their context, and respond to them by adjusting some key environmental parameters (temperature, light, sound, furnishings, etc.). Unlike the currently common approach, which is based on systems theory (i.e., adjusting the parameters of the environment to match some pre-defined use profile), the approach proposed in this paper is based on dynamic, collaborative design: it views the (built) environment as comprised of multiple independent object-agents, each of which is responsible for one small aspect of the environment. Each can sense the immediate changes pertaining to its domain of responsibility, and propose corrective measures, which are negotiated with other agents to form a collective response. The paper hypothesizes that such an approach can be made more context-sensitive and dynamic, is easily scaleable, and can respond to the needs of multiple different users of the environment at the same time. The paper presents the rationale for developing the multi-agent approach, its hypothetical implementation, and its application to hypothetical case studies.

title Cultural Difference in Colour Usages for Building Exteriors Focusing on Theme Park Buildings

summary The notion of globalisation has become widely spread in various fields, and accordingly, it is increasingly more important to take account of indigenous culture characteristics in each field. An as- pect of achieving globalisation, globalization with local consideration, is to consider the difference of colour usage between distinct cultures. This study suggests an approach to investigate the colour difference between eastern and western cultures with the case analysis of build- ing fac?ade colours in Disneyland Paris and Tokyo Disneyland. We an- alysed cultural colour usage characteristics and derived tendencies for both Paris and Tokyo Disneyland building fac?ade colours. To do this, we use image based k-means clustering algorithm and CIELAB colour space distances to explore colour characteristics. Our analysis indi- cates an overall colour usage tendency that Paris uses more green and bluish colours and Tokyo uses more red and yellowish colours for building fac?ades, based on CIELAB colour space values. The major motivation of this paper was to reflect the atmosphere and the mood of the space that can be easily felt but not readily expressible into a cultural colour palette. Eventually, by finding the characteristics of perceived colours, we hope to create a colour recommendation system for different cultures based on cultural clues.

summary The “Case Studies in Architecture” phase of a course in architectural design includes in-depth comparisons and analyses of architectural precedents. However, with the large number of cases now readily available, Web searching and navigation is a time-consuming, low precision activity. In the work described in this paper, we built eCAADe, an educational commendation system for the adaptive semantic Web to allow students to query and retrieve semantically for architectural cases during the case study phase of an architectural design process. In our suggested system, we built a Semantic Web for design knowledge representation to make query and retrieval efficient. We also applied a hybrid recommendation mechanism, which is combining both content-based filtering and collaborative filtering to help for students to find relevant cases more efficient and precise with their preferences. We illustrate our concepts with several concrete examples.

title A formal approach for the interpretation of cultural content(s): evolution of a Korean traditional pattern, Bosangwhamun

summary This paper develops a formal approach to investigate the evolution of a Korean traditional pattern, Bosangwhamun. The approach employs the structure of symbolic memes embedded in the pattern as a framework of hierarchical decomposition of a pattern to describe an evolutionary development process of a given pattern with a set of rules in shape grammar as style changes. Further, the formal descriptions of the given pattern become the basis for generating its variations. With this process, the validity of the rules and their appropriateness in the representation of Bosangwhamun are examined.

summary Physically-based manipulation can be recognized as a promising approach to implement interactive computational tools to solve the user participation problems. To support the designer’s justifications as well as to clarify the innately ambiguous expressions provided by the clients, we propose to build a fuzzy-based expert system integrated with a 3D physically based manipulation. This paper focuses on a system prototype for the client customization process in apartment plan design to exemplify our concepts.

title Developing the Reinforcement-Learning Child Agents for Measuring Play and Learning Performance in Kindergarten Design
doi https://doi.org/10.52842/conf.ecaade.2023.1.069

summary Although kindergarten design requires promoting play behaviours related to physical and social development and ensuring safety of children to support a child-oriented design, the systemic evaluation of design performance remains challenging because of the children’s dynamic play behaviours. As one solution, agent-based simulations have been applied in the design field, but there are limitations in reflecting children’s behavioural richness. To overcome this shortcoming, this study developed reinforcement learning (RL) child agents to compute the dynamic play behaviours associated with physical and social development. Several iterations were conducted to implement the RL agents’ play behaviours, and the results were incorporated into the simulation. To validate the play behaviour model, we conducted a case analysis with authentic and unbuilt kindergarten designs and measured the quantifiable design performance in terms of physical and social play behaviours and safety. The results indicated that the RL child agents enabled a holistic analysis and the calculation of generative behavioural responses, depending on physical variations. By facilitating an unknown design affordance, the RL-powered simulation model is expected to provide data-driven evidence to support a child-oriented design.

summary This study applies self-organization as a methodology to understand the complex process of city networks caused by interactions between spatial structures and individual behaviors. The agent-based simulations have been conducted to investigate the visible and invisible networks understanding the self-organized aspects of city development processes. To develop optimal future networks providing connectivity and accessibility this study investigates spatial network configurations from internal individual behavior and movement. As results, it was found that the spatial configurations of the agent movement trails match to the current district boundaries and the similar network patterns were seen in various control values of agent behavior settings. This study contributes to searching out the hierarchy of network structures which is an important factor for re-planning of the way system.

summary The unique integration of geometries and techniques allows the natural organisms to adapt to different environments in creative ways. In this study, a bio-inspired pneumatic facade is presented as a strategy to improve the efficiency of natural ventilation performance by controlling the adaptive openings. The Computational Fluid Dynamics simulation has been conducted to visualize airflows in order to explore how the changing configurations of openings enhance natural ventilation efficiency. The airflows are investigated with changes in wind speed and direction to find out the opening configurations which provide indoor airflows at the comfort level of velocities. As results, it was shown that indoor air velocities were modulated by controlling opening sizes, geometries and positions of the openings, and it was a beneficial strategy to apply the optimized opening configurations implementing automatic control. Also, the air distribution can be enhanced by changing opening configurations in changing conditions of wind speed and direction. An effective methodology for an intelligent façade opening control to encourage natural ventilation is presented in this study to deliver users comfort and efficiency.

title An Intuitive Heritage Education System for Learning Architectural Structures and Styles - Focusing on the historical Korean architectures
doi https://doi.org/10.52842/conf.ecaade.2016.2.529
source Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 529-537
summary Although national and international attention toward the cultural heritage is on a rise, there is a lack of public attention toward cultural heritage sites. One of the main problems is the lack of interaction and the visualization of cultural heritage on the sites. Especially Korean historical architectures are structurally complex and are not easily understood by common people. To improve the public awareness of architectural heritages, we propose a model-based diagnosis system to educate the visitors and tourists. The system is designed to guide the users to model an appropriate architecture in accordance with the era, location, and the usage. For the system, we built a robust set of cases based on the ontological structure we designed especially for architectural heritage education. It basically enables users to reconstruct buildings intuitively in six steps from bottom to top. A system evaluation was conducted on the affective, cognitive, operative aspect of the system at a heritage site. The results show well in terms of cognitive aspect but was evaluated poorly in terms of the operative aspect.

source Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 199-208
summary This paper presents a novel approach to the potential of mixed reality embodied in smart phones and ubiquitous environments. We analyzed the related works to the concept of context and mobile computing and then investigated into leading companies by interviewing senior manages of the mixed reality (MR) projects in Korea. As a result, the concept of context immersion is proposed for describing the various context relationships among the real locations, objects and persons. By considering the MR environments as a converged world, this paper characterizes the context immersion as the combination of the time & location-based, object-based and user-based contexts. Through the context immersion, users can be connected to the real life, not limited to the imagery world, thus experiencing strong immersion in the MR environments. At the end, we present the development direction for the future with a focus on the MR contents rather than the technical aspects.

summary Creating space is the essence of architectural design. Architects actually work with three-dimensional (3-D) space, although two-dimensional (2-D) drawings are perhaps the most commonly used design medium. It is thus valuable to help architects truly see 3-D space, while making drawings in 2-D. In addition, architects usually use symbols in their drawings to identify architectural concepts. By recognizing the symbols, it is possible to identify architectural configurations of the design. This paper introduces a symbol-based modeling tool—SpaceMaker—that allows architects to make freehand floor plans and apply symbols to identify different functional spaces. SpaceMaker then converts those floor plans into 3-D models according to the symbols.

source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 874-883
summary This paper describes the development of a constraint-based generative system (FSF system) to support the design of middle and high-rise apartment façades from architectural plans. Floor plan and façade designs are heavily interrelated, and, sometimes, the plan constrains the façade design during the design process. This relationship lends itself to apply constraint-based systems and we have designed the system to connect intelligently between apartment plan and façade. In our system, we define constraints into three categories: structural form, architectural style and function. We use genetic algorithm to generate plausible alternatives quickly and augmented by a constraint-based system, façades can be generated and modified much more easily in terms of real-time visual feedback for checking violence of the constraints and of dealing with updates smoothly through intelligent connecting plans to façades.

title Strength Guided Motion
source Computer Graphics. ACM, August, 1990. vol. 24: pp. 253-262 : ill. includes bibliography
summary A methodology and algorithm are presented that generate motion imitating the way humans complete a lifting task under various loading conditions. The path taken depends on 'natural' parameters: the figure geometry, the given load, the final destination, and especially, the strength model of the agent. Additional user controllable parameters of the motion are the comfort of the action and the perceived exertion of the agent. The algorithm uses this information to incrementally compute a motion path of the end-effector moving the load. It is therefore instantaneously adaptable to changing force, loading, and strength conditions. Various strategies are used to model human behavior that compute the driving torques as the situation changes. The algorithm runs in near-real time and offers an agent-dependent toolkit for fast path prediction. Example are presented for various tasks

source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 587-594
summary The paper addresses the influence of digital technology on architectural design and production, particularly considering the possibilities of sound for the design and conception of architecture based on the dynamic condition, which is present in the “everyday” and its permutations. The day-to-day condition is regarded as a highly dynamic flux of economic, social and political aspects and conceptually linked to sound and musical variation as guiding design principles, to actually retain and reflect the vitality of every day’s measure. We have traced precedents and cases in sound reproduction and its implications on the codification of architecture and have created a digital design tool in Max/MSP. The primary objective of the tool is to produce the corollary between sound reproduction and the conception and production of an architectonic codification, and ultimately to propose a strategy of architectural construct that has given way from the clarity of static geometry to the complexity in dynamic variability, that of dissonance. Virtual architecture and its techniques are considered to express and implement such permutations and induce a measure of change in every step and direction of the design process. The application of digital technology is regarded as the intervening of “apparatus” and to represent a different approach in relation to the prevailing regime.

title A fuzzy navigation system for mobile construction robots
source Automation in Construction 6 (2) (1997) pp. 97-107
summary Fuzzy navigation systems control a robot by implementing a fuzzy logic controller (FLC). Fuzzy navigation systems are simpler to implement than other navigation systems because they can handle infinite navigation situations with a finite set of rules. Existing fuzzy navigation systems for path finding in an unknown environment tend to find the shortest path in convex obstacle fields, but fail when obstacles are concave or placed continuously in certain configurations. This paper presents a fuzzy navigation system that can escape from concave and maze-like obstacle fields in an unknown environment. The system combines a tangent algorithm for path planning with sets of linguistic fuzzy control rules. In particular, we introduce the control rules for a Tracking mode of the FLC and improvements to the commonly used, intuitively reasonable tangent algorithm.

summary The Department of Architecture at the Massachusetts Institute of Technology has conducted a series of experimental design studios, as part of a larger ongoing research endeavour called The Design Studio of the Future, an interdisciplinary effort focusing on geographically distributed computer-mediated design and work group collaboration issues. A recent exploration was a collaborative design project joining geographically dispersed design students, faculty, researchers, and practitioners from Kumamoto University, Kyoto Institute of Technology, and MIT to examine the nature of computer networked collaborative environments and advanced computer-aided design technologies to support architectural education and practice. This paper will describe this project, which provided the students and faculty members with practical experience in the use of emerging technologies for collaboration, design, and communication in both the day-to-day activities of distributed groupwork as well as in the more formalized reviews.
