title	An Analysis of the Applications of Rapid Prototyping in Architecture

summary	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.

title	Optimization in the Balance between the Production Effort of E-learning Tutorials and their related Learning Outcome
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 122-126
summary	This paper provides evidence on the level of media richness that may be cost effective in the development of e-learning tutorials for teaching and learning computer visualization techniques. For such a purpose the author provides an analysis of low-cost / high-impact media rich products, the effort and cost required in their development and the measurement of related learning outcomes. Circa twenty years of R&D of multimedia and hypermedia applications for instruction have demonstrated the benefits of communicating relevant information to learners using engaging media. Based on this evidence, this paper assumes that due to the cognitive style of design students, the instructional packages for learning computer techniques for design visualization that are rich in media content, tend to be more effective. Available visualization technologies make the development of e-learning tutorials feasible and apparently the logical way to implement our instructional packages. However the question in the development of e-learning tutorials becomes a more strategic one when we are called to reach a level of optimization between producing a package with a basic standard, namely; text & still-graphic based tutorials, or a state-of-the-art package that is based on video demonstrations (more than enough?) that can accommodate the students’ learning requirements and also our production costs. The costs include the human resources (instructor, producers, assistants and others) and the material resources (hardware and software, copies, and others) involved in the creation of the e-learning tutorials. The key question is: What is good enough, and what is clearly superfluous? In order to confirm our hypothesis and propose a relevant balance between media richness and learning effectiveness, this paper describes an experiment in the use of two different levels of media richness as used to deliver instructions on the production of computer animations for design visualization. The students recruited for this experiment were fairly familiarized with the use of 3D modeling concepts and software, but had no previous knowledge of the techniques included in the tutorials; in specific; camera animation procedures. The students, separated in two groups, used one of the two methods; then they proceeded to apply their newly acquired skills in the production of an animation without using the help of any external means. The assessment of results was based on the quality of the final product and the students’ performance in the recall of the production procedures. Finally an interview with the students was conducted on their perception of what was accomplished from a metacognitive point of view. The results were processed in order to establish comparisons between the different levels of achievement and the students’ metacognitive assessment of learning. These results have helped us to create a clear set of recommendations for the production of e-learning tutorials and their conditions for implementation. The most beneficial characteristics of the two tested methods in relation to type of information, choice of media, method of information delivery, flexibility of production/editorial tools,! and overall cost of production, will be transferred into the development of a more refined product to be tested at larger scale.

title	PRIVATE/UN-PRIVATE SPACE: Scenario-based Digital Design for Enhancing User Awareness
doi	https://doi.org/10.52842/conf.caadria.2006.x.s8b

summary	Context awareness is important for human senses of places as well as human computer interaction. The aim of this research paper is focusing on controlling the user's privacy in a smart space which is adaptive to different users for enhancing the user's awareness in his diary life. In Environmental Psychology, the definition of privacy is that an individual has the control of deciding what information of himself is released to others, and under how he interact with others. (Westin 1970) And privacy is categorized as the linguistic privacy and visual privacy. (Sundstorm 1986). Solutions for privacy control: Plan Layout, Vision Boundary, Access Control and Architecture Metaphor - the transmission of information is not ascertainable for every single user. Although information are shown in public, but information is implied by cues and symbols. Only a certain user or a group of users have access to the full context of information. The methodology is to form an analytic framework to study the relationship between information, user and activities by using the computational supports derived from KitchenSense, ConceptNet, Python, 3d Studio Max and Flash; and to record patterns built up by users' behaviour and actions. Furthermore, the scenario-based simulation can envision the real world conditions by adding interfaces for enhancing user awareness.

title	Shape Grammar of Geometric Islamic Ornaments
doi	https://doi.org/10.52842/conf.ecaade.2006.290
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 290-297
summary	Shape grammars are the algorithmic systems used to analyze existing designs or create new ones. In spite of using text or symbols to express abstract representations, shape grammars aid to create novel designs through computational effort with shapes and rules. Many probabilities of rule selections and applications of these rules may generate emergent design solutions or create new design objectives. This paper aims to present the characteristics, shape grammar rules and historical background of geometrical ornaments in Islamic culture and to point out the possibilities of mathematics of symmetry. The knowledge presented in this paper can be used to generate new depictions and to gain new application areas like typography, wallpaper, landscape, façade design, tiling, jewelry, and textile designs. Even, these types of shape grammar studies can be used to open a novel approach as in Jean Nouvel’s “Arab World Institute” in Paris. The role of shape grammar analysis of geometrical Islamic ornaments explained in this paper is to increase the efficiency of architectural design education by facilitating the formal understanding of historical patterns. Novel use of shape grammars in education can enrich the designer’s ability to generate original designs. In this paper variants of Islamic ornaments are created with a CAAD program. A selected geometrical bezeme (ornament) from Islamic ornamental design is generated by encoding with a computer programming language. According to the generated bezeme, interaction scenario is as follows: Computer has the main control over grammar application. Only, some of the rules can be selected by the user. Varieties of this ornament are generated randomly through their line weight, line colors, filling types and filling colors. The shape grammar rules outlined in this paper are simple, but the resulting figures can be very inspiring. Furthermore, the endless potential for future design innovations is unlimited.

title	A Computational Approach to the Reconstruction of Surface Geometry from Early Temple Superstructures
source	International Journal of Architectural Computing vol. 3 - no. 4, 471-486
summary	Recovering the control or implicit geometry underlying temple architecture requires bringing together fragments of evidence from field measurements, relating these to mathematical and geometric descriptions in canonical texts and proposing "best-fit" constructive models. While scholars in the field have traditionally used manual methods, the innovative application of niche computational techniques can help extend the study of artefact geometry. This paper demonstrates the application of a hybrid computational approach to the problem of recovering the surface geometry of early temple superstructures. The approach combines field measurements of temples, close-range architectural photogrammetry, rule-based generation and parametric modelling. The computing of surface geometry comprises a rule-based global model governing the overall form of the superstructure, several local models for individual motifs using photogrammetry and an intermediate geometry model that combines the two. To explain the technique and the different models, the paper examines an illustrative example of surface geometry reconstruction based on studies undertaken on a tenth century stone superstructure from western India. The example demonstrates that a combination of computational methods yields sophisticated models of the constructive geometry underlying temple form and that these digital artefacts can form the basis for in depth comparative analysis of temples, arising out of similar techniques, spread over geography, culture and time.

title	SoundScapes & Architectural Spaces - Spatial sound research in digital architectural design
doi	https://doi.org/10.52842/conf.ecaade.2006.684
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 684-689
summary	The paper presents ongoing research focusing on the development of digital tools and methodologies for spatial design based on non-Euclidean geometries. It addresses the way sound can be used both conceptually and acoustically in the early stages of the design process, examining digital architectural design and modeling based on three-dimensional sound visualization and the acoustical analysis and evaluation of complex curved surface geometry. The paper describes SoundMatrix, the first part of a digital design tool created by using Max/Msp/Jitter, to assist in the preliminary design of building façades in small-scale urban environments, specifically studying the possibilities of curvature to decrease sound reflection between opposing street façades. Examples from a workshop with the SoundMatrix application illustrate the real-time 3D authoring and sound spatialisation processing currently implemented in the tool.

title	Generation of alternative designs in architectural problems using Shape Grammars defined with animation tools - A computer implementation of shape grammars using modelling and animation software
doi	https://doi.org/10.52842/conf.ecaade.2006.302
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 302-307
summary	We present a model of generation of alternative designs to selected architectural and spatial configurations of small complexity. Specifically we present a production pipeline of architectural / spatial configurations using the context of animation and time based design tools. Our model consists of time and space design constraints of boundaries / objects affecting a given architectural design, thus producing an alternative solution for every timeframe of the animation cycle. The alternative designs vary from the original according to their temporal and/or spatial distance from the original object on the animation time-line. The constraints placed upon the objects , used as actuators of Shape Grammars, are defined informally by the user/designer while their influence can vary according to time, speed, location, configuration of the object and/or the constraint itself. However the constraints further function as formal rules for the Shape Grammar creation so that our model tries to predict ahead of time the emergence of alternate designs. The employ of animation tools [shape driven curves, speed and time-line functions,parent child relationships] in the shape generation of our model empowers the user/designer to configure whole sets of shapes and designs interactively and without the need to define every solution independently. Simultaneously, a different, time-focused view of our model describes its use on designs that develop different configurations over time. Thus a duality of our model is established: either the animated schema may be a sum or family of various designs or the animated time-line represents a single design which changes over time. Finally the possibility of an automated analysis of every design is discussed, using Space Syntax diagrams so the designer can quickly evaluate the various spatial configurations produced by a single original.

title	The Holy Darkness: A Study of Light in Brihadeshvara Hindu Temple, in Tanjore, Tamilnadu, India (1010 AD)
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 425-428
summary	The study investigates how religious principles govern the treatment of light/darkness in sacred monument. Specifically, a digitized daylight simulation is used in the analysis of Brihadeshvara Hindu Temple, built in 1010 AD in Tanjore, Tamilnadu, India. This sacred monument, listed as one of UNESCO's World Heritage Sites, is an intriguing case study since the treatment of the 'holy light' in the temple is the treatment of the 'holy darkness'.In spite of the importance given to sun in ancient Hindu scriptures, natural light was used very sparsely in Hindu temples. According to Hindu religious belief, when a worshipper is in the presence of the divine, there should be nothing to distract his/her senses (including vision). Therefore, the innermost sanctum is shrouded in total darkness and the progression into the temple is a ritual movement where the devotee goes through the dynamic experience of the darkening spaces of the temple before reaching the dark sacred chamber (see Fig.1). The dictation of the Hindu faith to create this spiritual procession toward the 'holy darkness' is examined in the historic Brihadeshvara Temple by using Lightscape -- computerized lighting simulation software. To run the program, a 3-D CAD surface model of the temple was created and imported into Lightscape. Then the model was assigned materials and its openings and lighting systems were defined. The simulations were run on four interior horizontal (floor) and vertical (walls) surfaces, along four spaces of the procession in the temple. The simulation targeted three time frames: sunrise, sunset and at high noon on March 21st (the equinox). The location of Tanjore, India was used for light conditions. The Lightscape simulations used the process of radiosity to generate single frame daylight renderings along with light analysis of each surface. A lighting animation was then produced in Quick Time.The results of this analysis demonstrate that the average illumination values for specific surfaces of the temple along the procession sequence correspond to the schematic expectation depicted in Figure 1, i.e., a progressively decreased luminance towards the dark innermost chamber. Furthermore, the simulated values were compared to the Illuminating Engineering Society (IES) standards, which recommend ranges of luminance for specific visual tasks and areas. The comparisons showed that the average luminance in the temple, from the illuminated entrance in the east to the darker chamber in the west, is lower than the IES standards for 'public places with dark surroundings' for 'short temporary visits'. Finally, a morphological analysis of the temple along accepted daylight design guidelines corroborated the previous findings. The multi-method investigation of the relationship of light and darkness, light and objects, and the designated light quality in the Brihadeshvara Temple demonstrates the strong influence of the specific dictum of Hinduism on the light/darkness treatment in the temple. The paper concludes that digitized media such as computerized daylight simulations can examine the significance of light/darkness in sacred monuments as a spiritual experience. This quantitative investigation can augment the qualitative studies in the field of historic sacred architecture.

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.

title	Empathy over distance: Wearables as tools for augmenting Remote Emotional Connection
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 66-69
summary	Mainstream communication modes emphasise network speed, connection access, resolution, portability, and aesthetic design as primary to the success of their products. Within this vision a three by four centimetre screen and high resolution display are deemed adequate to emulate the intensities and complexities of face-to-face connection with loved ones. They allow us to ‘be there with you’ from wherever we might be. Yet interpersonal communication is a massively complex phenomenon. It involves a plethora of micro-activities which occur at a physical, physiological, and psychological level allowing us to recognise at a cellular scale intention, motive and emotional authenticity. Our conscious and non-conscious involvement in spatially collocated communication is substantial due to these myriad channels of real-time bi-directional information transfer. While contemporary communications technologies have the capacity to mediate our relationships, they fall short of encouraging the richness of spatially co-present interaction. The research discussed in this paper investigates the potential expansion of remote connection when electronically enhanced apparel is incorporated into the communications mix. Rather than pursuing the manifold functionalities of traditional communications media the garments discussed focus solely on the goal of enhancing empathy between physically distant individuals. This paper reports on the development and testing of a range of garments that conduct presence information between remotely located people. The garments sense, process, transmit and receive the heartbeat wavelength (ECG). They are enabled with ECG sensors, signal processing equipment, small vibration motors, and radio transceivers which allow users to ‘feel’ the heartbeat of a remote friend/lover/relative as vibration through their garment. The prototypes aim to enrich the remote communications experience through reintroducing an embodied, tactile dimension that is present in face-to-face communication. A range of user testing trials will be discussed which have been undertaken to assess the impact of the garments at a conscious and a non-conscious level. Conscious experiences were gauged through qualitative testing, by way of interviews and unsolicited written reactions, which have provided a range of engaging emotional responses. Non-conscious physiological reactions were assessed by recording ECG throughout user-testing periods. This data has been processed using HRV (heart rate variability) analysis software, running on MatLab. Preliminary results suggest that users have strong conscious and non-conscious reactions to the experience of wearing the prototype garments. The paper will describe the data processing techniques and findings of the user testing trials. The development of biosignal sensing garments has raised a range of issues including: innovative potentials for embedded peripheral awareness media; the expansion of the classical body to incorporate remotely sensed information; the issue of data semantics and the development of intensely personal non-verbal languages; and the issue of corporeal privacy when one’s biological information is exposed for potential download. They also bring into question how our bodily experiences might change when we incorporate remote sensory systems.

title	Visualizing the Operative and Analytic: Representing the Digital Fabrication Feedback Loop and Managing the Digital Exchange
source	International Journal of Architectural Computing vol. 4 - no. 3, 79-97
summary	Digital architecture is process-based and reliant upon a conversation between digital visualization, analysis, and production. With the complexity of information generated in process-based digital practices, we need to effectively manage and exchange the information. Feedback loops are integral to this process/product, and thus require extensive management of complex versions of visual and data related information. Quite a lot of scholarly attention has been focused upon highlighting innovative projects using digital fabrication and serial customization. However, there is a scarcity of scholarly work about innovations in visualizing and representing the design data integral in this feedback loop. This paper will examine innovative representational devices such as the matrix, sectioning, layering, bracketing, nesting, and other new forms of organizing, visualizing, analyzing, and simulating complex data, intent upon communicating multiple levels of operations during the design and fabrication process. With a rigorous taxonomy of operative and analytic devices for process-based digital design development, we can begin to outline a trajectory for future evolutions in practice. This writing is an attempt to make a few steps in this direction, and demonstrate some of these new representational ideas in practice.

title	Web Based Collaboration (for Free) Using Wikis in Design Studios
doi	https://doi.org/10.52842/conf.acadia.2006.190
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 190-199
summary	This paper presents a case study of the use of Wikis by students in a landscape architecture design studio to evaluate the suitability of Wikis for enhancing student collaboration in the site analysis and preliminary design stage of a project. It was anticipated that using Wikis to facilitate collaboration would provide alternatives to conventional peer to peer collaboration. In addition, Wikis could enhance feedback between the course coordinator and students. The Wiki was used to collect, compile and present data for the purpose of a precedent study of cultural and physical analysis of a site in New Zealand, for which the technology proved successful. The Wiki was less successful in contributing to the collaborative preliminary design of the project. The following discussion and presentation will include the evaluation of online Wiki services, the process used in the design studio, strengths and weaknesses observed, and opportunities for future research.

summary	This paper presents a study of the comparison of tangible user interfaces and graphical user interfaces on designers’ cognitive actions. We conducted individual design experiments using the protocol analysis method. The results reveal that designers using the tabletop system with 3D blocks reasoned more about spatial relationships among 3D objects, while the designers using the keyboard and mouse reasoned more about individual 3D objects.

title	“Not Every new Monday…”: on using computer-games technology in architectural design education
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	The application of new media is common practice in architectural offices and complements traditional forms of presentation such as drawings and physical ‘haptic’ models. Other interactive forms of presentation are also already available, for example in the realm of computer gaming, however the transfer and application of game engines to an architectural environment has not yet been explored in any depth. This paper looks at how “new media” can be used as a means of communicating architectonic information without simply emulating an already available traditional means of representation. We discuss the process of learning how “new media” (the computer as a multi media) can be used as a tool for the analysis and reconstruction of architecture. Using Mies van der Rohe’s unrealised project for a brick country house as a basis, a project was devised which communicates valuable design and analysis skills and also allowed us to explore the use of “new media” and to draw conclusions for teaching and research as well as to critically assess the opportunities, limitations and risks involved.

title	ASSISTANT TOOL FOR ARCHITECTURAL LAYOUT DESIGN BY GENETIC ALGORITHM
doi	https://doi.org/10.52842/conf.caadria.2006.x.s6m
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 641-643
summary	Architectural design is a very complicated process. It contains many sequences within the design process that the architects have to take into considerations. Within the process, the architect will look for every feasible schematic to make the best decision for developing the final design process. However, the preliminary design involves both conceptual and schematic design that concern about quantitative analysis and qualitative analysis. The objective of this research is to utilize an assistant method or tool to help form a preliminary design and a thinking process by using genetic algorithm to find the feasible solutions for conceptual and schematic design.

title	NEW METHODS FOR URBAN DESIGN AND ARCHITECTURE USING THE VR TECHNIQUE AND ANALYSIS OF THE PSYCHOLOGICAL INFLUENCE
doi	https://doi.org/10.52842/conf.caadria.2006.x.p0n
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 495-501
summary	Urban plan and architecture require the use of VR systems. We adapted the buildings into a VR system, and then performed a virtual realization in the world’s largest dome at Matsushita Electric Works, Ltd. Walking or flying through life-size space was enabled. We viewed the planned future scenes that featured real size, space composition, and a simulated environment. The construction, the materials and colors of the building were examined. In addition, VR system on PC was applied to city planning and architectural design and a number of novel functions were added to the VR system by plug-in, which assisted and facilitated the design process. The stereoscopic thinking mode in 3-D space can inspire and comprehend more directly the ideas of design, and confirm the intended effects. We accordingly carried out a further study on users operating the VR system to investigate their responses of “like” or “dislike” towards the real time adjustments of design effect at identical viewpoints. Fractals analysis was conducted to demonstrate physically the influence of real time 3-dimentional design and presentation on the psychological trends of subjective judgment. Our findings pave the way for future research on monitoring psychological impacts on observers of VR system during design process.

title	Towards a Digital Design Teaching Tool - A look at the ideas that should define a digital design primer
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 373-386
summary	Architecture in the 21st century has become an increasingly complex affair. In addition to new social and cultural norms, architects are inundated with constantly changing information regarding new materials, sustainable processes, and complex building types. This state of affairs has also affected the expectations placed on architectural education. Critics (in diverse spheres) have expressed concerns about the lack of requisite skills of graduates that characterise good design thinking strategies as well as promote responsible design. It has been proposed by this author in other forums that by using digital technology to empower design learning, we can allow students to confidently use (through reading and analysis) their sketches to develop conceptual ideas that reconcile disparate elements into a habitable, environmentally friendly and architecturally responsible whole that is fit for purpose, cost effective, sustainable and a delight to clients and users. This paper will seek to discuss one of the concepts that govern such a tool. It will start by delineating the problem (discussed earlier in the abstract) before outlining the concepts or principles that a design teaching tool should adhere to. These concepts acknowledge the importance for the tool to reflect the nature of design tasks, facilitate learning and be accessible to all learning types. The paper will then focus on one concept - the nature of design tasks. The subsequent sections will describe an information structure borne from this idea and make mention of a current prototype of the tool. The paper will conclude with a discussion of the strengths of considering this concept.

title	A 3D, interactive, multilayered, web-enabled model as a tool for multiple sets of end user groups: A case study and end user analysis
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 392-396
summary	This research undertakes a case study involving focus groups of potential end users, to identify how a successful digital tool could be created using new and emerging technologies, to accommodate the multiple needs of these end users. 2005 saw the completion of a research paper, which proposed that a single, 3 dimensional digital model of a city forming a core for many different information systems, is a better approach to the needs of the city than many individual models optimised for each information system. The case for the single 3D model was evaluated through the research, development, delivery and analysis of a prototype 3 Dimensional model of Wellington City, New Zealand, presenting different ‘views’ of information in Wellington: a rendered visualisation in an animated “walkthrough”; the impact of planning constraints on daylight; interactive “plots” of property values. The development and delivery of the prototype model was analysed in regards to how complex, costly and time consuming it may be to exploit one base model for several purposes; and also therefore how beneficial, affordable and potentially successful a single model may be. The prototype model was created to test the idea, and therefore provided conclusions based on a limited feasibility analysis - with four potential information layers modelled and two potential delivery methods tested. The prototype model and user analysis results were presented in a research report that suggested further research and development of a single model could be very beneficial: Positive feedback from potential end users and data providers, and examples of potential data mining opportunities forming the basis of the need for continued research. 2006 sees the research continue as an 18 month research project in conjunction with an industry partner, Terralink International, (http://www.terralink.co.nz/). Terralink International Limited provides GIS and mapping solutions which according to their web site: “enable better business management.” The company maintains a national resource of “imagery, cartography, and spatial databases” and provides consultancy services linking these to company databases through GIS systems. The research investigates the potential for 3 dimensional, interactive, multilayered models to enhance delivery of information to multiple end user groups. The research method uses functional prototypes in end-user focus group workshops. These workshops, consisting of a combination of presentations, hands on interactive examples, group discussions, and individual feedback surveys, aim to establish how a tool might best be developed to communicate to a wide range of end users. The means of delivery whether a stand alone tool or web-based is a key element of the user group workshop assessment process. Note: The submission of the prototype tool (via video or interactive media) would greatly increase the effectiveness of the research presentation. Ability to include such media would be greatly appreciated.
