title	iSphere: A Proximity-based 3D Input Interface
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 281-290
summary	This paper presents a 24 degree of freedom input device for 3D modeling. iSphere uses the proximity information of pulling-out and pressing-in capacitive sensors to manipulate 12 control points of a 3D surface simultaneously . The iSphere dodecahedron is demonstrated manipulating an analog parametric model with high-level modeling concepts like push or pull the 3D surfaces. Our pilot experiment shows that iSphere saved many steps of selecting the control point and going through menus. Experts were used to those extra steps and still found themselves doing them but novices saved significant time for surface shaping tasks. 3D systems are benefited to execute high-level modeling commands, but lacking of fidelity is a great issue of analog input device.

summary	Recently, more and more researchers dedicated in the development of human computer interaction for CAD systems, such as gestural input of three dimensional coordinates (Lee, Hu, and Selker, 2005), flexible manipulation of NURBS objects (Cohen, Markosian, Zeleznik, Hughes, and Barzel, 1999; Emmerik, 1990), and the creation of force feedback (Wu, 2003). These research results indicated that the more intuitive control the device can provide in modeling process, the more creative solutions can be generated (Lee, Hu, and Selker, 2005; Schweikardt and Gross, 2000; Wu, 2003).

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 799-805
summary	After numerous studies and practical of use, field and laboratory measurements, carried out among the years 1994 and 1999, we arrived to the elaboration and presentation of a methodology for the bioclimatic design and energetically sustainable that already takes two books publications. With the support of more than 600 figures that facilitate the understanding of the concepts explained in the books and 26 computer software and databases, that are attached to the second book, the work is facilitated so that designers of buildings that have not been never in contact with a certain climate, or that they don’t have sufficiently assumed by means of the observation of the particularities of a certain climatic situation, to understand the form in that the climate influence their design, condition or determine the design solutions and averge strategies that will choose when carrying out an architecture work.

title	Using the Mobile Augmented Reality Techniques for Construction Management
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 396-403
doi	https://doi.org/10.52842/conf.caadria.2005.396
summary	In this paper we attempt to develop a new system called “C-Navi” for construction site simulation and management system. By integrating AR technology with mobile computing, the new system will extend the abilities of AR systems to be implemented in large outdoor space. The concept of 4D CAD system is utilized by integrating related information and displaying them in the time-based visualization approach. Our system could help with decision making and also act as a tool for improved communications between project partners.

title	Applying Scientific Simulation to Integrate Thermoelectric Conductor Module into Architectural Design – Smart Wall for Thermal Comfort
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. 200-210
doi	https://doi.org/10.52842/conf.acadia.2005.200
summary	This paper presents the innovative architectural design concept, which is to integrate the new material and technology into the building design to achieve the thermal comfort and at the same time reduce the energy consumption of the building by making use of the renewable energy, including solar and wind energy. The system is developed based on the idea of regional thermal comfort in building. The advantage of the system is the environmental friendly approach, costless operation, reliability, flexibility, scalability and adaptability for the integration to the building design. With the design concept, we tried to do two application designs in two virtual sites. One is a badminton court for the 2008 Beijing Olympic Games and the other is a cooling pond in a shopping mall. We will introduce how computational simulation can contribute to the prediction of the performance of the design. We will also discuss how the computation simulation can help in the design optimization process. Through the development of the new design integration of the material to the building, we would like to feedback to the material industry to encourage further collaboration and development in the material enhancement, so that both industries and the society can benefit from the advancement.

title	Virtual Architecture as Representation for Creative Design Process - Through a Collaborative eDesign Studio
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 37-45
doi	https://doi.org/10.52842/conf.ecaade.2005.037
summary	Using Virtual Architecture (VA) as a general scheme for representations to sustain the reflection activities involved in the design process can help students to initiate creative design ideas. Because of its implicit abstract nature, VA can be used, to represent original ideas or processes, or well-known architectural theories to articulate design ideas. Furthermore, VA as a mean of expression, turn out to be a source of inspiration for students who perceive it as medium with very few limits with which to develop, explore and express their design intuitions. A recent collaborative edesign studio experience is reported to illustrate the benefit observed. Using three examples out of ten student projects, we show how designs and design process have been characterized by those virtual representations. In fall semester 2004, the edesign studio took place between the Schools of Architecture of Toulouse and Université Laval in Québec. VA was both an academic and a studio topic at Laval while the other school students had a traditional design task to tackle, namely the rehabilitation of Chapou University Residences for students in Toulouse. Students from both schools composed each edesign team. In addition, three common architectural themes were web-documented and introduced to both classes: room, as defined by Louis Kahn: “a space which knows what it wants to be is a room”; color, as an architectural medium in dialectic with structure; and body-space relationships, as articulated by Gilles Deleuze and its projection to cyberspace. From the edesign studio results, we are arguing that virtual architecture should be looked at not only as new domain to be investigated by architects and taught in academic studios but also as a new medium of design to develop and explore design intuitions through virtual representations.

title	Improving spatial ability using a Web-based Virtual Environment (WbVE)
source	Automation in Construction
summary	Spatial ability is one of the cognitive means used in problem solving activities particularly when manipulating and processing visuo-spatial information. With the increasing use of network communication, conventional teaching and learning has shifted towards the development of network environments, online learning, real-time interaction and high quality multi-user collaboration. This paper presents our experiment using a Web-based Virtual Environment (WbVE) that has improved a group of pre-service teachers' spatial ability understanding for teaching Engineering Drawing for secondary school subjects. The experiment is carried out in Universiti Pendidikan Sultan Idris (UPSI) comprising of 98 pre-service teachers taking the Computer Aided-Design (CAD) course. Selected subjects were pre-tested at the beginning of the semester with spatial tests focusing on mental rotation and spatial visualization to provide the baseline measurement. A desktop WbVE, which was employed and tested in the CAD laboratories to improve their spatial ability for five weeks of instructional treatment, will be demonstrated. Post-testing of spatial tests revealed significantly the overall spatial ability improvements as measured by the test scores. This paper concludes with a discussion on the impact of WbVE spatial learning that will be used as a precedent in the development of the VE teaching and learning prototypes for secondary school in Malaysia.

title	A Framework For Generating And Evolving Building Designs
source	International Journal of Architectural Computing vol. 3 - no. 4, 449-470
summary	This paper describes a comprehensive framework for generative evolutionary design. The key problem that is identified is generating alternative designs with an appropriate level of variability. Within the proposed framework, the design process is split into two phases: in the first phase, the design team develops and encodes the essential and identifiable character of the designs to be generated and evolved; in the second phase, the design team uses an evolutionary system to generate and evolve designs that embody this character. This approach allows design variability to be carefully controlled. In order to verify the feasibility of the proposed framework, a generative process capable of generating controlled variability is implemented and demonstrated.

doi	https://doi.org/10.52842/conf.caadria.2005.463
summary	This paper describes a generative evolutionary design system that aims to fulfil two key requirements: customisability and scalability. Customisability is required in order to allow the design team to incorporate personalised and idiosyncratic rules and representations. Scalability is required in order to allow large complex designs to be generated and evolved without performance being adversely affected. In order to fulfil these requirements, a computational architecture has been developed that differs significantly from existing evolutionary systems. In order to verify the feasibility of the this architecture, the generative process capable of creating three-dimensional building models has been implemented and demonstrated.

title	Spatio-Temporally Navigable Representation and Communication of Urban Cultural Heritage
source	Proceedings: VSMM 2005 International Conference on Virtual Systems and Multimedia
summary	Virtual environments are effective tools for the representation and communication of cultural heritage. We suggest that an interactive, immersive and dynamic navigation of the virtual representation of the urban environment will not only convey the essence of the culture and the changes it underwent in a more comprehensible manner, but will engender a 'sense of place'—genius loci— in the visitors. This cognitive mode will help them learn about much more than the geometry and materiality of the city: it will make them 'feel' part of the event itself. By presenting a socially shareable experience, we aim to introduce the medium the character of a genuine place, and make it a social venue for active exploration, discussion and interaction. Virtual reality surpasses both traditional media and 3D-models and offers what they cannot. The affordances of the medium, however, also have the potential to destroy the sense of place it strives to engender. It can do so by allowing a kind of ‘time travel,’ to different periods in the history of the site. This ability locates visitors not only spatially, but also temporally. Everyday experience helps us understand the meaning of spatial boundedness, but does not prepare us to deal with temporal boundedness: sensing the presence of fellow visitors at different times. In this paper we describe our experiences in producing spatio-temporally navigable virtual reconstructions of two distinct culturally significant historic sites: the neolithic village of Çatalhöyük, and the medieval city of Cairo. We demonstrate the use of spatio-temporal navigation through a dynamic, chronologically layered model that can be browsed by multiple users at the same time. Such a dynamic system for representing chronological architectural events requires the extension of our conception of place into the temporal domain. We introduce a new concept, temporal field of view (t-FOV) and discuss how it can aid us in resolving an intrinsic challenge introduced by the representation of the temporal dimension in virtual environments.

summary	In 1990, due to the traditional architecture design and construction method difficult to build the complicated and non-geometry free-form Fish Structure in Barcelona, architect Frank Gehry started learn from the field of aerospace to utilize CAD/CAM technology in design and manufacture process. He created the free-form fish model in CAD system and exported the digital CAD model data to CAM machine (RP and CNC) to fabricate the design components, and finally assembled on the site. Gehry pioneered in the new digital design process in using CAD/CAM technology or so-called digital fabrication. It becomes an important issue recently as the CAD/CAM technology progressively act as the new digital design media in architectural design and construction process (Ryder et al., 2002; Kolarevic, 2003). Furthermore, in the field of architecture professional, some commercial computer systems had been developed on purpose of standardizes the digital design process in using CAD/CAM fabrication such as Gehry Technologies formed by Gehry Partners; SmartGeometry Group in Europe and Objectile proposed by Bernard Cache. Researchers in the research field like Mark Burry, Larry Sass, Branko Kolarevic, Schodek and others are enthusiastic about the exploration of the role of CAD/CAM fabrication as new design media in design process (Burry, 2002; Schodek et al., 2005; Lee, 2005).

title	Developing a User Location Prediction Model for Ubiquitous Computing

summary	Our prediction model is based on the development of “Semantic Location Model.” It embodies geometrical and topological information which can increase the efficiency in prediction and make it easy to manipulate the prediction model. Data mining is being implemented to extract the inhabitant's location patterns generated day by day. As a result, the self-learning system will be able to semantically predict the inhabitant's location in advance. This context-aware system brings about the key component of the ubiquitous computing environment. First, we explain the semantic location model and data mining methods. Then the location prediction model for the ubiquitous computing system is described in details. Finally, the prototype system is introduced to demonstrate and evaluate our prediction model.

doi	https://doi.org/10.52842/conf.acadia.2005.142
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	Talking Dirty: Formal and Informal Communication in Construction Projects
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 265-274
summary	We analyse the emergence and use of formal and informal communication tools in group working to aid in understanding the complexity of construction projects. Our test case is the design and build of an interactive digital installation in an exhibition space, involving students. After the project we conducted focus group studies to elicit insights into the effective use of the digital communications available for the project. We recount key insights from the study and examine how digital messaging devices are contributing to or hindering creative discussion. Whereas the construction process is concerned with the removal of dirt and re-ordering, in this paper we reflect on construction’s ritualistic, contractual and unauthorized aspects, and dirt’s role within them. We draw on Bakhtin’s theories of the carnival in exploring ritual, and the mixing of the un-sanctioned (rumour) with the official (contractual). How does dirt impinge on issues of communication, open discussion, and the move towards “partnering” in construction practice? We conjecture that while physical dirt might be unpleasant, the removal of other forms of metaphorical dirt hampers construction as an efficient and creative process.

In this research, based on experts’ opinions about future space and lifestyle, we create a creative scenario and produce a video through video camera, digital image process, computer animation. In addition, virtual studio, camera matching and motion capture are added to simulate how people would interact with the spaces in the city life.

summary	It has been a ubiquitous problem that users generally do not participate in housing design process. In Taiwan, however, apartment buyers have a chance to customize their plan until the construction takes place. This paper attempts to solve the problem about user participation in apartment plan design by integrating scenario-based design and case-based design approaches. We build an interactive computational tool for designers to support user participation in the apartment plan design process and to prove our concepts by some concrete examples.

doi	https://doi.org/10.52842/conf.acadia.2005.226
summary	The research paper exemplifies a novel information integrated design technique developed at ONL (Oosterhuis and Lenard), Netherlands, specifically appropriated for envisaging complex geometric forms. The ‘informed design technique’, apart from being highly instrumental in conceptualizing and generating the geometric component constituting architectural form in a parametric manner, is also efficiently utilized for precise computer aided manufacturing and construction of the speculated form. Geometric complexities inherent in contemporary architectural constructs and the time spent in appropriation of such topologies, fueled the ‘informed design’ approach, which caters to issues of timely construction, precision oriented design and production (visual and material) and parametric modeling attuned to budgetary fluctuations. This design-research approach has been tested and deployed by ONL, for conceiving ‘the Acoustic Barrier’ project, Utrecht Leidsche Rijn in the Netherlands and is treated as a generic case for exemplifying the ‘informed design’ technique in this research paper. The design methodology encourages visualizing architectural substantiations from a systems perspective and envisages upon a rule based adaptive systems approach involving extrapolation of contextual dynamics/ground data in terms of logical ‘rules’. These rules/conditionalities form the basis for spawning parametric logistics to be mapped upon geometric counterparts exemplifying the conception. The simulated parametric relations bind dimensional aspects (length, width, height etc.) of the geometric construct in a relational manner, eventually culminating in a 3D spatial envelope. This evolved envelope is subsequently intersected with a ‘parametric spatio-constructive grid’, creating specific intersecting points between the two. The hence extorted ‘point cloud’ configuration serves as a generic information field concerning highly specific coordinates, parameters and values for each individual point/constructive node it embodies. The relations between these points are directly linked with precise displacements of structural profiles and related scaling factors of cladding materials. Parallel to this object oriented modeling approach, a detailed database (soft/information component) is also maintained to administer the relations between the obtained points. To be able to derive constructible structural and cladding components from the point cloud configuration customized Scripts (combination of Lisp and Max scripts) process the point cloud database. The programmed script-routines, iteratively run calculations to generate steel-wireframes, steel lattice-structure and cladding panels along with their dimensions and execution drawing data. Optimization-routines are also programmed to make rectifications and small adjustments in the calculated data. This precise information is further communicated with CNC milling machines to manifest complex sectional profiles formulating the construct hence enabling timely and effective construction of the conceptualized form.
