title Human visual perceptions in built environment: Applying image-based approach for architectural cue recognition
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 328-341
summary This paper first presents a review on visual perception in the built environment and human vision simulation. Followed by the description of the Standard Feature Model of visual cortex (SFM), an architectural cue recognition model is proposed using SFM-based features. Based on the findings of the experiments it can be concluded that the visual differences between architectural cues are too subtle to realistically simulate human vision for the SFM model.

title Computational Fluid Dynamics in Building Design Practice
source ACADIA 2020: Distributed Proximities / Volume I: Technical Papers [Proceedings of the 40th Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-95213-0].

summary This paper provides a state-of-the-art of computational fluid dynamics (CFD) in the building industry. Two methods were used to find this new knowledge: a series of interviews with leading architecture, engineering, and software professionals; and a series of tests in which CFD software was evaluated using comparable criteria. The paper reports findings in technology, workflows, projects, current unmet needs, and future directions. In buildings, airflow is fundamental for heating and cooling, as well as occupant comfort and productivity. Despite its importance, the design of airflow systems is outside the realm of much of architectural design practice; but with advances in digital tools, it is now possible for architects to integrate air flow into their building design workflows (Peters and Peters 2018). As Chen (2009) states, “In order to regulate the indoor air parameters, it is essential to have suitable tools to predict ventilation performance in buildings.” By enabling scientific data to be conveyed in a visual process that provides useful analytical information to designers (Hartog and Koutamanis 2000), computer performance simulations have opened up new territories for design “by introducing environments in which we can manipulate and observe” (Kaijima et al. 2013). Beyond comfort and productivity, in recent months it has emerged that air flow may also be a matter of life and death. With the current global pandemic of SARS-CoV-2, it is indoor environments where infections most often happen (Qian et al. 2020). To design architecture in a post-COVID-19 environment will require an in-depth understanding of how air flows through space.

title Multi-touch - the future of design interaction
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 557-572.
summary The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title An agent-based street simulator
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 833- 846
summary This paper aims to study interactions between a behavioral model of pedestrians and urban spaces, and regards micro-scale urban spaces as its target. This paper suggests constructing and analyzing a pedestrian behavioral model using the “Attention Theory”, and introducing the rules and attributes of agent behavior oriented simulation. Based on the validation of actual street cases, the findings show that the pedestrians can be represented by an agent program, and behavioral reactions of walking agents under different stimulus can be further simulated.

title A Prototype Using Multi-Agent Based Simulation in Spatial Analysis and Planning

doi https://doi.org/10.52842/conf.caadria.2009.513
summary Pedestrian’s movements and spatial cognition in urban environments are main issues for urban designers in urban spatial planning and analysis. This paper aims to study interactions between a behavioural model of pedestrians and urban spaces. The pedestrians can be represented by an agent program, and behavioural reactions of walking agents under different stimulus can be further simulated. Thus, this study suggests that, a correlation study on pedestrian behaviours and spatial environments become the criterion for urban designers in order to help them create better flows.

title Retrieving Lost Space With Tangible Augmented Reality
source Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 135-142
doi https://doi.org/10.52842/conf.caadria.2009.135
summary Tangible Augmented Reality can be an innovative way for designers to understand the spatial conception. Due to the high integration of tactile and vision, this realm allows users to gain a better understanding how to retrieve ‘lost space’ in an urban context. By using a variety of visualisation methods, such as wireframe and transparencies, hidden or other ways unperceivable (lost) space is made available. With the aid of Tangible Augmented Reality designers are subsequently able to evaluate the design context and its solution more holistically. This paper argues that the retrieval of lost space enhances the design communication.

doi https://doi.org/10.52842/conf.caadria.2009.737
summary The purpose of this paper is to investigate colour combination tools of visual communication designers’ need. Participants were twentythree students of Visual Communication Design Graduate School to follow the questionnaire survey and seven students of Design Doctoral Program Graduate School to follow the interview survey. The findings display that visual communication designers seldom use web-based colour combination systems. Based on the findings, we developed a colour combination support system: the adobe illustrator plug-in to proof this hypothesis. The databases of the tool use the book of “colour combination charts”, and the tool of this paper provides a personal database.

summary The goal to reach Simplicity has been the key point of Human- Computer Interface since 1980s. In this research, we would like to know what Simplicity is and how to reach it. We used case studies to get two factors of Simplicity, which are the information modeling and the experience of perception through senses. Based on the factors, we implemented a prototype to refine the concepts of simplicity. The prototype was a new attempt to consider only the simplicity of HCI. Further research efforts on emotion, creativity, and aesthetics related to simplicity are important.

title Preliminary tectonic phenomena of diversified architectural spatial forms in digital age
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 599-608
doi https://doi.org/10.52842/conf.caadria.2010.599
summary The research on tectonics in the architectural field began from the middle of nineteenth century and in recent twenty years digital technology gradually developed and permeated through the field of architecture. Liu and Lim (2006, 2009) integrated classic and digital tectonic factors a present framework of new tectonics. However, the previous studies related to the tectonics in this digital age were only on architectural cases that use a great deal of digital media. The research wants to know what and how the tectonic factors affect the different spatial forms of modern architecture and focused on a case study of the diversified spatial forms, orthogonal, folding and curving. The results show the classic tectonic thinking is imperative until now. It is critical to prove the significance of adding the new digital tectonic factors in digital age.

summary Recently we developed a prototype general shape grammar system, called Grammar Environment (Li et al. 2009). It differs from other systems in that it aims to support designers who design with shape grammars. One task of such a system is to support users in editing shapes. The guidelines that we followed in developing Grammar Environment suggested that the shape editing system should both be integrated into the system and be powerful as a drawing tool. This seemed to be contradictory. We decided to make two shape editors: one stronger on integration, the other on drawing power.

title A Prototype System for developing two- and Three-Dimensional Shape Grammars

doi https://doi.org/10.52842/conf.caadria.2009.717
summary A number of researchers have developed shape grammar systems, with a variety of aims. These systems all help users (to varying degrees) to run grammars, but not to develop grammars. However, we believe that developing grammars is also work and needs to be supported. A system to do this would make it easier and more convenient for people using grammars to do design work. Following the generate-test model, we design and implement a prototype system that supports the user in editing grammars, testing grammars, and switching easily between the two types of activity. We emphasize the graphic nature of the task: the user is all the time working with graphic objects, namely shapes.

source ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 140-151
doi https://doi.org/10.52842/conf.acadia.2016.140
summary Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 572- 584
summary This paper discusses the proposed idea of using Tangible Augmented Reality to gain design knowledge since information sharing has been limited by one way receiving knowledge without enough response and interaction in the learning process. The new instructional technology is not only available through visual cues, but also opens up multi channels from different cues. It describes some guidelines for space utilizing between buildings and followed by a scenario. The proposed system offers three levels of information which affects aspects of individuals experience of space as they move the digital contents in the real environment.

source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 861- 874
summary Pedestrians move according to their internal states and the spatial information that they perceive at their locations. We use Markov chain to define the state transition of a pedestrian as a stochastic process, and the concept of cellular automata to simulate the way information disseminates in space. We have implemented an agent-based computer program to observe some emergent behaviors from the interactions between pedestrians and the information space they are surrounded. It is expected that the representational model can be used to assist designers in analyzing the relation between building plan and the circulation pattern.
