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.

title Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

title Constraint-Based Design in Participatory Housing Planning
source International Journal of Architectural Computing vol. 6 - no. 1, pp. 97-117
summary We introduce some novel ideas for a constraint-based design strategy to support participatory housing planning processes in Latin America. The following lines intend to open the discussion on the requirements and effect of the computer implementation of a constraint satisfaction approach to solve elementary design problems in architectural practice. The case study applies to the building massing design problem posed by the Chilean urban regulatory framework that addresses single-family affordable houses. Two different implementation criteria are being tested in an ongoing series of trials providing further considerations. One prototype uses MAXON's CINEMA4D XPRESSO® visual scripting environment to set up a semi-automated design environment which allows users to edit one feature-based 3D model of massing alternative at a time. The other prototype uses ILOG's OPL STUDIO® constraint programming environment to achieve fully automated search and 2D visualization of all possible solution alternatives to separate subdomains of the building massing design problem.

title Designing (tools (for designing (tools for ...))))
source RMIT University, Melbourne
summary Outcomes of innovative designing are frequently described as enabling us in achieving more desirable futures. How can we design and innovate so as to enable future processes of design and innovation? To investigate this question, this thesis probes the conditions, possibilities and limitations of toolmaking for novelty and knowledge generation, or in other words, it examines designing for designing. The focus of this thesis is on the development of digital design tools that support the reconciliation of conflicting criteria centred on architectural geometry. Of particular interest are the roles of methodological approaches and of biological analogies as guides in toolmaking for design, as well as the possibility of generalising design tools beyond the contexts from which they originate. The presented investigation consists of an applied toolmaking study and a subsequent reflective analysis using second- order cybernetics as a theoretical framework. Observations made during the toolmaking study suggest that biological analogies can, in informal ways, inspire designing, including the designing of design tools. Design tools seem to enable the generation of novelty and knowledge beyond the contexts in and for which they are developed only if their users apply them in ways unanticipated by the toolmaker. Abstract The reflective analysis offers theoretical explanations for these observations based on aspects of second-order cybernetics. These aspects include the modelling of designing as a conversation, different relationships between observers (such as designers) and systems (such as designers engaged in their projects), the distinction between coded and uncoded knowledge, as well as processes underlying the production and the restriction of meaning. Initially aimed at the development of generally applicable, prescriptive digital tools for designing, the presented work results in a personal descriptive model of novelty and knowledge generation in science and design. This shift indicates a perspective change from a positivist to a relativist outlook on designing, which was accomplished over the course of the study. Investigating theory and practice of designing and of science, this study establishes an epistemological model of designing that accommodates and extends a number of theoretical concepts others have previously proposed. According to this model, both design and science generate and encode new knowledge through conversational processes, in which open-minded perception appears to be of greater innovative power than efforts to exercise control. The presented work substantiates and exemplifies radical constructivist theory of knowledge and novelty production, establishes correspondences between systems theory and design research theory and implies that mainstream scientific theories and practices are insufficient to account for and to guide innovation.

title Adopting Building Information Modeling (BIM) as Collaboration Platform in the Design Industry
doi https://doi.org/10.52842/conf.caadria.2008.053
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 53-60
summary This paper discusses the preliminary findings of an ongoing research project aimed at developing a technological, operational and strategic analysis of adopting BIM in AEC/FM (Architecture-Engineering-Construction/Facility Management) industry as a collaboration tool. Outcomes of the project will provide specifications and guidelines as well as establish industry standards for implementing BIM in practice. This research primarily focuses on BIM model servers as a collaboration platform, and hence the guidelines are aimed at enhancing collaboration capabilities. This paper reports on the findings from: (1) a critical review of latest BIM literature and commercial applications, and (2) workshops with focus groups on changing work-practice, role of technology, current perception and expectations of BIM. Layout for case studies being undertaken is presented. These findings provide a base to develop comprehensive software specifications and national guidelines for BIM with particular emphasis on BIM model servers as collaboration platforms.

summary This paper outlines two major aspects of virtual environments for architectural design. On the one hand it focusses on how to use virtual reality as an extended tool to generate spatial design by building up and interacting with a three-dimensional digital model. On the other hand it describes - based on a case study - the relation between perception, interaction and immersion in virtual environments. Both approaches can be interconnected to a continues design process, that allows the designer to create, manipulate, visualize and decide on spatial concepts in a holistic three-dimensional simulation.

title A collaborative project experience in an architectural framework, working with Open Source applications and physical computing [Diseño de Plataformas Digitales e Interactivas: una experiencia educativa trabajando colaborativamente con aplicaciones de Código Abierto y Computación Física]
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary Nowadays, thanks to the telecommunication revolution and therefore the massive spread of Internet, we have seen the come up of international architectural offices with branches located in different continent, working in a collaborative fashion, surpassing physical and time frontiers. At the same time, the multidisciplinary work between designers, architects, engineers, programmers and even biologist, between others, have been taking place in the new network society. All transformations also supported by the arising of FOSS (Free Open Source Software) and the virtual communities behind them, which allow the creation of non-traditional or specific software, the association between disciplines, and also, the formation of meeting scenarios for a mixture of individuals coming up with multiple motivation to coexist in collaborative environment. Furthermore, it is possible to argue that Open Source applications are also the reflection of a social movement, based on the open creation and exchange of information and knowledge. Do the appeared of FOSS compel us to re-think our working and teaching methods? Do they allow new modes of organizing and collaborating inside our architectural practices?. This paper would like to address these questions, by presenting the results of the “Experience Design” course, which by implementing teaching methods based on Open Source principles and cutting-edge tools, seeks to approach students to these new “way of do”, knowledge and methodologies, and overall, focus them on the science behind the computer. This paper describes the “Experience Design” course, in which architectural graduate students of Universidad Diego Portales (Chile), put for first time their hands on the creation of interactive interfaces. By acquiring basic knowledge of programming and physical computing, students built in a collaborative way a responsive physical installation. The course use as applications “Processing” and “Arduino”. The first one is an Open Source programming language and environment for users who want to program images, animation, and interactions. It has a visual context and serve as a software sketchbook and professional production tool. Processing is a project initiated by Ben Fry and Casey Reas, at the MIT Media Lab (www.processing.org). The second is an Open Source electronics prototyping platform based on flexible, easy-to-use hardware and software. Arduino has a microcontroller (programmed with Processing language) which can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators (www.arduino.cc). Both environments shared a growing community of people working in related projects and extending useful assistance for beginners. In this paper it is presented the current state of the pilot course and some of the initials results collected during the process. Students and teacher’s debates and evaluations of the experience have been exposed. Together with a critical evaluation in relation to the accomplishment of the effort of place together different disciplines in one collaborative project akin, architecture, design, programming and electronic. Finally, futures modifications of the course are discussed, together with consideration to take in account at the moment of bring Open Source and programming culture into the student curriculum.

title Towards Effective Interfaces for General Architectural Learning

source Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 569-576
summary The persistence of difficulties related to communication of the participants in the design process is mainly due to the diversity of interests and the abilities of visual communication. The research presented has been focused especially on the first issue - professional vs. general public relations. It builds on the idea that general public should be approached with both: adaptation to its abilities and with additional teaching to improve these abilities. The initial questions lead to the isolation of (i) elements and (ii) characteristics that could possibly define architectural educational interfaces for general public. The experiment puts the prototypical eco-spatial interface to the test in primary schools and observes the effect the level of interactivity has on learning outcomes. The results show possible ways of enhancing the efficiency of GUI-s and help developers and designers evaluate and fine-tune such tools for the process of general architectural learning.

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 A paradigm shift in the world of architecture brought by the recent developments in visualization and communication technology not only offers us drastically different ways to collaborate, but also questions traditional location dependent collaborations. This new technology offers us new possibilities for a more phenomenologically rich mode of creative activity and participation. The goal of the Participatory Design Studio was to allow architecture students in multiple locations to collaborate in real-time by sharing computational resources, geometric datasets, and multimedia content including high-definition video. The technologies involved in this research include the National LambdaRail (layer 3, PacketNet with 1Gb/s connection) and CA*net 4 (Canadian broadband layer 2 with 10gb/s lightpath connectivity) allowing Standard Definition videoconference, utilization of Deep Computing Visualization, Remote Visual Networking (RVN) and Web Service access and control of the APN devices through the dashboard solution that makes integration seamless to the workflow and transparent to the user.

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

title Design Rationalization of Irregular Cellular Structures
source International Journal of Architectural Computing vol. 6 - no. 2, pp. 197-211
summary Complex geometries found in nature are increasingly used as images and analogies for the creation of form and space in architectural design. To be able to construct the resulting complex building forms, strategies to handle the resulting production requirements are necessary. In the example of a design project for a Japanese noodle bar, a strategy for the realization of an irregular cellular spatial structure is presented. In order to represent its complex geometry, building principles relating to foam are applied to transform and optimize the design, which is based on hexagonal, cellular compartments defining the different interior spaces. The principles are converted into software code and implemented into a digital design toolbox to be used within a 3D-modelling environment. Utilizing the tools within the redesign process made a rationalization of the cellular structures possible without sacrificing the desired visual irregularity. The toolbox also enables the extraction of the cell geometry to support the generation of production documents. The result is the dramatic reduction of production effort to realize the complex cellular structures by keeping a maximum of design flexibility and desired visual appearance.

summary Designers; architects and artists in general always proceed with one crucial goal in their mind when they design: to be able to materialize the scheme in their mind. There are some tools that can help designers to test their design to see if it will be successfully constructed or functioned as close as possible as the way they imagined or expected; visual simulation models in digital environments of the designs are such important tools for architectural design process, but these models does not provide enough data to determine the design’s applicability. Therefore, the need of a tool that would work with the designer in order to determine the possibility of whether the design could be built or not as the way designer imagined, is vital.

title Creating Metallic Color Sequences for an Architectural Wall

source Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 308-315
summary A metallic paint scheme for an architectural wall is created using computer aided color appearance design techniques. New computer graphic hardware that allows real-time rendering of complex reflectance functions is employed to produce photo-realistic images of the metallic paint applied to the surface of the wall. An interpolation scheme is developed that permits one and two dimensional metallic shade sequences to be determined between individual bricks in a single row of the wall and between the complete rows of bricks that compose the wall. Paint formulation software, originally developed for auto refinish applications, is used to determine the paint mixtures necessary to realize the metallic colors in the design. A prototype of the wall is constructed and exhibited in a museum gallery.

summary The paper discusses the use and possible applications of stereoscopic projection and anaglyph representation for the design-process and visualization of architectural spaces and three-dimensional objects. As the topic of stereoscopic vision is quiet broad and has a long tradition in various fields (photography, art, virtual reality) the paper focuses on the implementation of anaglyph representation in 3D-Modeling-Software as a tool to support spatial perception within the design process. Against this background and based on a test-series with 113 students the benefits and conditions of spatial perception, vision and sense using anaglyph representation are examined.

summary Digital media, with the capacity to master complexity, has permitted an unprecedented ability to reinterpret natural processes. An infinite number of realities can emerge from their interpretations that can be developed into physical structures or spatial models that can further be appropriated to inform the design of architecture. In this paper the potential of these digital interpretations to inform architectural design processes will be discussed. Demonstrating how digital media can operate as an interface that couples information with cognitive processes I will show how digital media can be constructed in order to intensify our perception of our natural environment. Examples from projects that were developed with students during the spring semester of 2008 at Georgia Institute of Technology will be used to support the argument.

title Multi-Directional Interrelationship Approach For Hybrid Interactive Design Tool For High-Rise Building

summary The role of computers in architectural design is constantly increasing, as may be seen in the efforts to develop generative design tools which are focused on helping create innovative results. Some of these are generated by sets of rules, constraints, theoretical models and algorithms, for which the computer is used as the implementing tool. This research introduces a new approach in hybrid interactive design tools, which are focused on the clustered and hectic urban context in the modern age, meaning that architecture is continuously developing vertically, in high-rise buildings. The main point in this research will be the abandoned gap in connecting the internal functions and external appearance. This is another main point which cannot be ignored in designing high rises, which ideally contain both internal and external perceptive aesthetics. The scope of this research will cover three aspects: Function, Perception, and Proportion. Therefore, the work flow of this design tool will be a multi-directional interrelationship between these three steps: 1) internal function and external form generation by various types of constraints, 2) internal function and external form inspection, and 3) internal function and external form modification by the users.

summary The focus of the research presented in this paper asks how a designer can create a flexible system of physical making which can accommodate multiple programmatic functions within a smooth whole, rather than creating an a priori singular formal object. This adaptable system of construction works through the development of an intelligent CAD model that can be mapped to a flexible manufacturing mechanism, i.e. a reconfigurable mold. This system of manufacturing can be used to cast totally unique solid modules without creating a unique mold for each part by manipulating the topological structure of the system. This approach takes the notion of mass-customization beyond the expensive and unsustainable one-offs that the design world has seen recently, and into a new paradigm of a sustainable, economically viable world of mass-customizable form and space.

title MxR: A Physical Model-Based Mixed Reality Interface for Design Collaboration, Simulation, Visualization and Form Generation
doi https://doi.org/10.52842/conf.acadia.2008.464
source Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 464-471
summary MxR—pronounced “mixer”—is a Mixed/Augmented Reality system intended to support collaboration during early phases of architectural design. MxR allows an interdisciplinary group of practitioners and stakeholders to gather around a table, discuss and test different hypotheses, visualize results, simulate different physical systems, and generate simple forms. MxR is also a test-bed for collaborative interactions and demonstrates different configuration potentials, from exploration of individual alternatives to group discussion around a physical model. As a MR-VR transitional interface, MxR allows for movement along the reality-virtuality continuum, while employing a simple tangible user-interface and a MagicLens interaction technique.
