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	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

summary	Digital Fabrication and Hybrid Interface: Lessons in Agriculture :abstract Two vitally important fields of work in architecture and computing—in digital fabrication methods and in the development of interfaces between digital and analog systems—can find new forms in their combination with one another. Moreover, a recent such experiment in the production of landscape rather than building not only suggests a number of implications for architectural work, but of ecological, economic and urban structures that underlie the projects’s visible formal and aesthetic orders. This project, “Hyperculture: Earth as Interface,” studied the potential outcomes of modifying a commonly employed information infrastructure for the optimization of agricultural production throughout most of America’s heartland; and that same infrastructure’s latent flexibility to operate in both “read” and “write” modes, as a means for collaborative input and diversified, shared output. In the context of industrialized agriculture, this work not only negotiates seemingly contradictory demands with diametrically opposed ecological and social outcomes; but also shows the fabrication of landscape as suggestive of other, more architectural applications in the built environment. The Hyperculture project is sited within several contexts: industrial, geographically local, ecological, and within the digital protocols of landscape processing known as “precision agriculture.” Today, these typically work together toward the surprising result of unvariegated repetition, known commonly as monoculture. After decades of monoculture’s proliferation, its numerous inefficiencies have come under broad recent scrutiny, leading to diverse thinking on ways to redress seemingly conflicting demands such as industry’s reliance on mass-production and automation; the demand for variety or customization in consumer markets; and even regulatory inquiries into the ecological and zoning harms brought by undiversified land use. Monoculture, in short, is proving unsustainable from economic, environmental, and even aesthetic and zoning standpoints. But its handling in digital interfaces, remote sensing and algorithmically directed fabrication is not.

title	A Framework of Haptic Design Parameters for Architects: Sensory Paradox Between Content and Representation
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. 685-700.
summary	Architects‚Äîlike other designers‚Äîtend to think, know and work in a visual way. In design research, this way of knowing and working is highly valued as paramount to design expertise (Cross 1982, 2006). In case of architecture, however, it is not only a particular strength, but may as well be regarded as a serious weakness. The absence of non-visual features in traditional architectural spatial representations indicates how these are disregarded as important elements in conceiving space (Dischinger 2006). This bias towards vision, and the suppression of other senses‚Äîin the way architecture is conceived, taught and critiqued‚Äîresults in a disappearance of sensory qualities (Pallasmaa 2005). Nevertheless, if architects design with more attention to non visual senses, they are able to contribute to more inclusive environments. Indeed if an environment offers a range of sensory triggers, people with different sensory capacities are able to navigate and enjoy it. Rather than implementing as many sensory triggers as possible, the intention is to make buildings and spaces accessible and enjoyable for more people, in line with the objective of inclusive design (Clarkson et al. 2007), also called Design for All or Universal Design (Ostroff 2001). Within this overall objective, the aim of our study is to develop haptic design parameters that support architects during design in paying more attention to the role of haptics, i.e. the sense of touch, in the built environment by informing them about the haptic implications of their design decisions. In the context of our study, haptic design parameters are defined as variables that can be decided upon by designers throughout the design process, and the value of which determines the haptic characteristics of the resulting design. These characteristics are based on the expertise of people who are congenitally blind, as they are more attentive to non visual information, and of professional caregivers working with them. The parameters do not intend to be prescriptive, nor to impose a particular method. Instead they seek to facilitate a more inclusive design attitude by informing designers and helping them to think differently. As the insights from the empirical studies with people born blind and caregivers have been reported elsewhere (Authors 2010), this paper starts by outlining the haptic design parameters resulting from them. Following the classification of haptics into active, dynamic and passive touch, the built environment unfolds into surfaces that can act as ‚Äúmovement‚Äù, ‚Äúguiding‚Äù and/or ‚Äúrest‚Äù plane. Furthermore design techniques are suggested to check the haptic qualities during the design process. Subsequently, the paper reports on a focus group interview/workshop with professional architects to assess the usability of the haptic design parameters for design practice. The architects were then asked to try out the parameters in the context of a concrete design project. The reactions suggest that the participating architects immediately picked up the underlying idea of the parameters, and recognized their relevance in relation to the design project at stake, but that their representation confronts us with a sensory paradox: although the parameters question the impact of the visual in architectural design, they are meant to be used by designers, who are used to think, know and work in a visual way.

summary	The Attractive City Generator is an interactive installation with which users can create or rearrange virtual cities by placing and moving physical objects. Through the set of simple inputs that the users provide and which represent city areas, landscapes or landmarks, the ACG is capable of creating complex and growing cities. In addition, a plethora of factual feedback on these cities is calculated. Becoming physically involved enhances the learningprocess and increases the user’s interest. The users are drawn to the colourful and simple interface. Due to the practical feedback that the city returns, the users can feel more attached to the city they have created. A dynamic dialogue is formed between the city and its creators, that involves the wishes of the users versus the needs of the virtual city, the practical interaction on the table versus the theoretical calculations taking place inside the computer, the physical input versus the digital output.

summary	This paper presents an overview of the current developments in people flow analysis in Buro Happold’s analytical group SMART Solutions. The role of people flow analysis has become an established one, within many leading consultancy firms with their own specialist groups supporting the architects and planners in the design of buildings and urban spaces. This paper proposes that the key development in the progression of this work is a due to a change in emphasis, away from a passive analysis task where its key role is to validate assumptions of flow and alleviate areas of high concern to using the process as a design instigator/driver. The new paradigm emerging, involves calculating people flow at the conceptual stage of a project in collaboration with the respective architectural firm, and using this information as a primary design input. This paper describes and analyses the two objectives set out by Buro Happold’s SMART group in order to improve the process of design; firstly to make it more prominent in the design environment and secondly to see if it has the potential to work as a design driver. These objectives create a design methodology defined by people flow and suggest value in innovating and conceiving of robust simple methods of improving designs.

summary	Online communities use a “wall” as a place to articulate non - synchronic communication among its members. Such a place, however, poorly explores the metaphor of the wall as a means of enhancing online experiences. Online “walls” do not explore or challenge the richness of a real wall, and they do not embrace new experiences that are only possible in the digital world. In order to tackle these issues, this paper analyzes three movie scenes where the everyday perception of the wall is altered by madness and estrangement. Finally, the paper suggests how these perceptions of the wall could be integrated into interfaces using touch screen technologies.

title	Automated Cost Analysis of Concept Design BIM Models
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. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

summary	We present a simulation platform to evaluate procedurally generated 3d city models with a set of agents representing urban street actors and pedestrians towards greenhouse gas emissions from transportation. Our aim is to give architects and urban planners an empiric tool to analyze, predict and quantify traffic fluctuations over time, and define the number of occupants, individual traffic and public transport in a city. In this project we show that the allocation of functions within a city is an important factor for the appearanceof traffic. The occupant’s decisions where they want to go are defined by the allocation of functions – and the distance defines the mode of transportation. We simulate the decision processes and gain information about the path, the mode of transportation, and the emissions they produce, and individual experiences like stress and effort. The autonomous driving cars are equipped with an acceleration based emission model allowing us to evaluate the inpact of jammed streets on the emission of cars.

summary	The paper follows the development of digital tools for architects and briefly discusses their utility within education and practice. The move from static CAD tools to time based media followed by programmatic processes and virtual environment design is addressing the evolution of the profession and to an extent reflects practitioners’ needs. The paper focuses on the notion of interactivity and how it is been addressed in various fields. Borrowing from computer science and game design the author presents a course dealing with designing interactivity, responsiveness and users feeding their input back in the design. The aim of the paper is to analyse and support a new set of tools in architectural curricula that will implement interactivity and integrate it into spatial design leading to a holistic approach promoting intelligence, hybridity and responsiveness of the built environment. Following, the elaboration of the rationale, a brief discussion on tools and project directions is carried out.

The intention of the work is to investigate multi-objective criteria both as a material system and as a processing system by creating prototypes with structural integrity, where the thermal energy flow through the prototype, to be understood as a membrane, can be controlled and the visual transparency altered. The work shows performance based feedback systems and physical prototype models driven by information streaming, screening, and application.

title	Applying augmented reality for data interaction and collaboration in BIM
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 511-520
doi	https://doi.org/10.52842/conf.caadria.2010.511
summary	Building Information Modelling (BIM) is expected to enable efficient collaboration, improved data integrity, distributed and flexible data sharing, intelligent documentation, and high-quality outcome, through enhanced performance analysis, and expedited multi-disciplinary planning and coordination. Despite these apparent benefits, the collaboration across the architecture, engineering and construction (AEC) disciplines is largely based on the exchange of 2D drawings. This paper reports the findings from a research project that aims at developing measures to enhance BIM-based collaboration in the AEC industry. Based on focus group interviews with industry participants and case studies of BIM applications, visualisation was identified as an interactive platform across the design and non-design disciplines. It is argued that visualisation can enhance the motivation for BIM-based collaboration through integration of advanced visualisation techniques such as virtual reality (VR) and augmented reality (AR). An AR interface for a BIM server is also presented and discussed in the paper. AR can open up potential opportunities for exploring alternatives to data representation, organisation and interaction, supporting seamless collaboration in BIM.

title	A Computational Medium for the Conceptual Design of Mix-Use Projects
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 109-116
summary	Mix use development is receiving wide attention for its unique sustainable benefits. Nevertheless, the planning and designing of successful mixed use projects in today's environment is a complex matrix of skill sets and necessary collaborations between various stakeholders and design professionals. From a design point of view, architects are required to manage and coordinate large information sets, which are many time at odds with one another. The expansive space of knowledge and information is at its best vague and substantially ill-structured. A situation that continues to overburden architects mental and intellectual ability to understand, address and communicate the design issue. In the face of this complex condition, designers are gravitating towards information modeling to manage and organize the expansive data. However, is becoming increasingly evident that current building information modeling applications are less suited for early design activity due to their interrupted and rigid workflows. Against this background, this paper presents a theoretical framework for a computational medium to support the designer during early phases of exploring and investigating design alternatives for mix-use projects. The focus is on the conjecture between programming and conceptual design phase; when uncertainty and ambiguity as at its maximum, and the absence of computational support continues to be the norm. It must be noted however, the aim of the medium is not to formulate or automate design answers. Rather, to support designers by augmenting and enhancing their ability to interpret, understand, and communicate the diverse and multi-faceted design issue. In literature on interpretation, Hans-Georg Gadamer explains that understanding is contingent on an act of construction. To understand something is to construct it. In light of this explanation. To help designers understand the design issue, is to help them construct it. To this end, the computational medium discussed in this paper is conceived to model (construct) the mix-use architectural program. In effect, turning it into a dynamic and interactive information model in the form of a graph (network). This is an important development because it will enable an entirely new level of interaction between the designer and the design-problem. It will allow the designer to gather, view, query and repurpose the information in novel ways. It will offer the designer a new context to foster knowledge and understanding about the ill-structured and vague design issue. Additionally, the medium would serve well to communicate and share knowledge between the various stakeholders and design professionals. Central to the discussion are two questions: First, how can architects model the design program using a graph? Second, what is the nature of the proposed computational medium; namely, its components and defining properties?

summary	This paper explores the use of subdivision algorithms for the production of three-dimensional ornament. In a first step, this paper presents modifications to the Catmull Clark and Doo Sabin processes’ weighting schemes. In a second step, it proposes how these modified processes can be applied specifically to the generation of ornament. It presents methods for specifying weights using parameters both intrinsic and extrinsic to the mesh. Strategies for working with both very uniform and more differentiated input meshes are considered.

title	(In:)forming Interactive Architectural Systems, Case of the xMAiA Meta-model

doi	https://doi.org/10.52842/conf.acadia.2010.203
summary	This paper positions the domain of interactive architecture (iA) and searches for an appropriate model for structure and processing of information in the design and operation of such architecture. It is shown that there are different approaches to ways in which iA system models can be defined, each with numerous advantages and disadvantages. However, due to complexity of encountered problems, application of such models can be only partially validated by simulation and hence their design is inherently dependent on creation of operational and experiential full-scale prototypes of the systems these models represent. Another observation is the lack of correspondence between existing iA models and other contemporary models of computation for architectural geometry, fabrication and engineering. A meta-model for extensible multi-agent interactive architecture (xMAiA) is consequently proposed as a remedy to this situation. xMAiA meta-model is aimed to provide an open framework for integrated evolution, development and operation of interactive architectural systems. It delivers an extensible platform, in which diverse, project-specific models and approaches can be implemented, tested, and further evolved. Such a platform has the potential to empower agile development and operation of interactive architectural ecologies, as well as to substantially facilitate integration of creative design and experiential prototyping from day-1 of project design and development cycle. An example application conforming to the xMAiA meta-model is consequently presented and illustrated with a case study project performed in the university education context.

summary	The miniature replicas of multi-billion dollar property development projects provide every year a spectacle of the vast imagination of architects and master developers at Cityscape Dubai exhibition. The technical aspect of the model-making industry component is a complex one in that it often engages the modelling of very subtle structures such as twisted towers. One illustration of these is the Infinity Tower in Dubai Marina (designed by SOM). To be completed in 2011, this 330-metre high-rise is composed of 80 floors and is intended to be the world’s tallest high-rise featuring a 90_ twist. Each floor rotates by 1.2 degrees to attain the full 90_ spiral, creating the shape of a helix. The paper discusses the physical modelling of this tower, with a description of both the digital and the constructive parts.

summary	Urban design, perhaps even more than architecture, is a timedependent discipline. With its multi-layered complexities, from individual buildings to entire regions, decisions made at one level, that may not show effect immediately, may prove to have disastrous consequences further down the line. The need to incorporate time-based simulations in urban modeling, and the demand for a means of evaluating the changes have led to explorations with multi-agent systems in computation that allow for decisions to be decentralized. From the first basic rule-based system of Conway’s Game of Life [1] to recent urban simulations developed at institutions like the ETH Zurich [2], or UCL CASA [3], these programs synthesize the various exigencies into complex simulations so that the designer may make informed decisions. It is however not enough to simply use parametrics in urban design. Rules or desires implemented at one scale may not apply to another, while isolating each scalar layer for independent study reverts to the disjunctive and shortsighted practices of past planning decisions. Central to current parametric research in urban design is the need to deal with multiple scales of urbanism with specific intelligence that can then feed back into the collective system: a networked parametric environment. This paper will present the results from a city-generator, developed in Processing by Dino Rossi, Dominik Zausinger and Jeannette Kuo, using multiagent systems that operate interactively at various scales.
