summary The paper documents the design and implementation of an interactive multi-sensory environment (DETOUR) created by the interdisciplinary group VE_Design for an international open-air exhibition in Athens, Greece during the summer of 2004. The paper describes the creative process followed throughout the project and registers how computers, sensors and effectors have been utilised to either facilitate the creation of electronically mediated experiences or support the design. The architectural concept of the multi-sensory installation is analyzed in relation to its potential for creating communicative experiences as well as addressing physical form simulations. Notions such as ephemeral structures, parasites, social space, game as art and communication are discussed. The body – space interaction is investigated, enabling the team to elaborate on a modular construction. Finally, the impact of the work is discussed on the basis of recorded observations by visitors.

summary This conference paper examines experimental design exercises on a simulated model in relation to designing on a physical model. In the initial design phases, the process of designing on both a haptic and digital model is analysed with regard to the didactic objectives. In this context, only form-related aesthetic aspects are discussed. The starting point is the didactic necessity of imparting to students the process of designing on spatial models. Reduced to form determination, the question examined is for which aspects of design theory the potentials of real and virtual models, as well as of the interaction of both types, can be exploited.

title VIRTUAL CONTEXT - INVESTIGATING THE CHARACTERISTICS AND OPPORTUNITIES OF DIGITAL VISUALISATION MEDIA FOR SITUATED APPROACHES TO ARCHITECTURAL DESIGN IN AN URBAN ENVIRONMENT
source Delft University Press
summary This research initiative addresses the issue of Design in relation to Virtual Context.

Central to this study are the innovative potentials and instrumental opportunities of computer based media techniques, capable of generating interactive models and changing perspectives for the benefit of urban and architectural design.

The ambition was to not only make a contribution to the existing body of knowledge concerning digital technologies and their applications, but explore theoretical conditions which might help define and stimulate further study.

From the outset, the focus was on furthering the opportunities for computer based representation media in creative design. On the basis of a series of explorative studies the subject of this research was targeted: the issue of Design in Context, or more specifically: Design(ing) in a Virtual Context.

During the process there was a marked shift in the conception of the subject from – more or less immersive – VR technologies in the direction of approaches which might be expected to become readily available in practice and education and could be effective in actual design processes. This insight also brought about a shift in emphasis from realism per-se towards creating a sense of situatedness.

The design representation system which was developed was intended to not just allow for one type of model view, but to afford an array of different views, from which the designer would be able to choose freely, depending on the phase and focus of design as well as personal preferences. A series of interface prototypes and support tools were developed especially and successively tested experimentally. 

For the intended final design driven experimental study, different virtual context models were considered. Eventually, an integral –  purely fictitious – design ‘environment’ was constructed in the computer, so that the workings of the proposed system and its components would be tested systematically.

A conscious choice was made for an in depth study, on a relatively modest scale, which would a certain amount of mutual involvement between designer and researcher, to confront the participants with the finer aspects of the proposed system in a relatively short time and to gather detailed data. A half dozen design professionals were invited to participate in a closely monitored experimental exercise.

The results of this study therefore do not offer straightforward, indisputable facts, to be considered representative for the design community as a whole, but indicate that the working methods of the individual designers – when discovering aspects of the site, developing and presenting proposals and reflecting on the qualities of represented designs – tend to vary considerably. For this reason the interactive representation system proved to be of value. Participants could express different view preferences, with more or less realistic image modes being used in different phases of their design developments, with varying experiences of situatedness. Some of the design professionals participants were very appreciative of the system’s opportunities, others tended to be more ‘set in their ways’.

The results of this experimental study indicate that there may particularly be opportunities for interface applications which are able to function interactively, offering individual designers –  as well as others involved in evaluating design proposals – a variety of tools with which to approach specific design artefacts in their changing contexts. Virtual models can play not only an important role as a ‘reminder’ for the designer but also to other parties playing an active role in the design and implementation processes. Interactive environment models are not only promising as exploration tools for existing sites, but could be valuable to test the impact of a design on its location. This could be especially interesting if the site is difficult or impossible to visit or as yet a virtual construction. In addition such an approach might be beneficial for objective comparison and evaluation of design proposals in competitions and in education as well as in on-line collaborative design projects where the context is still in the process of being developed.

title Towards a Virtual Reality Tool for Lighting Communication and Analysis in Urban Environments

summary The objective of this paper is to evaluate the use of virtual reality as a potential decision-making tool to cognitively evaluate urban daylighting ambiences. This paper evaluates the solar effects visual perception in a real urban path in comparison to a virtual urban path in order to extract the characteristics of these effects and use them to figure out the necessary conditions for generating a physical and sensitive phenomena simulation. The comparison is based on questionnaires and interviews with participants on their judgements on sunlight during their walk through the chosen path. Our results highlight the relation between perception and the context of the urban environment, and prove that -in spite of its limits- virtual reality is able to simulate a large part of real solar effects.

title Log Knot
source ACADIA 2020: Distributed Proximities / Volume II: Projects [Proceedings of the 40th Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-95253-6]. Online and Global. 24-30 October 2020. edited by M. Yablonina, A. Marcus, S. Doyle, M. del Campo, V. Ago, B. Slocum. 114-119.
summary Log Knot, developed by the Robotic Construction Laboratory (RCL) at Cornell University, is a robotically fabricated architectural installation that establishes a method for variable compound timber curvature creation utilizing both regular and irregular roundwood geometries. Moreover, the project develops methods for minimal formwork assembly and moment force optimization of customized mortise and tenon joints. Following the logic of a figure-8 knot, the project consists of an infinite loop of roundwood, curving three-dimensionally along its length. There are a variety of techniques to generate single curvature in wood structures – such as steam bending (Wright et al., 2013) or glue lamination (Issa and Kmeid, 2005) – but only a few techniques to generate complex curvature from raw material within a single wooden structural element exist. To construct complex curvature, the research team developed a simple method that can easily be replicated. First, the log is compartmentalized, establishing a series of discrete parts. Second, the parts are reconfigured into a complex curvature “whole” by carefully manipulating the assembly angles and joints between the logs. Timber components reconfigured in such a manner can either follow planar curvature profiles or spatial compound curvature profiles. Based on knowledge gained from the initial joinery tests, the research team developed a custom tri-fold mortise and tenon joint, which is self-supportive during assembly and able to resist bending in multiple directions. Using the tri-fold mortise and tenon joint, a number of full-scale prototypes were created to test the structural capacity of the overall assembly. Various structural optimization protocols are deployed in the Log Knot project. While the global knot form is derived from spatial considerations – albeit within the structurally sound framework of a closed-loop knot structure – the project is structurally optimized at a local level, closely calibrating structural cross-sections, joinery details, and joint rotation in relation to prevailing load conditions.

summary The impact of ubiquitous digital technologies on the analysis and synthesis of our urban environment is undoubtedly great. The urban topography is overlaid by an invisible, yet very tangible digital topography that is increasingly affecting our urban life. As W. J. Mitchell (Mitchell 2005) pointed out, the digital revolution has filled our world with “electronic instruments of displacement” that “embed the virtual in the physical, and weave it seamlessly into daily urban life”. The mobile phone, the most integrated mobile device is closely related to the notion of a digital identity, our personal identity on this digital space. The Bluetooth is the mainly used direct communication protocol between mobile phones today and in this scope, each device has its own unique ID, its “MAC address”. This paper investigates the potential use of recording and analysing Bluetooth enabled devices in the urban scale in understanding the interrelation between the physical and the digital topographies.

summary New digital tools or information technologies are providing the means for architects to realize unprecedented architectural creations. Unfortunately, the promise these technologies hold is far from their potential expression in the built physical environment. A contributing cause to this disjunctive state is the multiplicity of languages and knowledge sets employed by the various team members or actors engaged in a building project. From the cost models of the owners to the shop drawings of the fabricators, each actor views the project in terms specific to their individual discipline. In order to successfully engage the building process, these new technologies must account for this condition and develop means in which to span across traditional boundaries. This paper will examine the disjointed and fractured nature of the building project and identify opportunities for the deployment of information technologies to bridge boundaries, ultimately providing for and delivering architectural projects of unparalleled precedence. Specific aspects inherent to these technologies will be examined to understand where their application may benefit the building process. The key attributes this paper will focus on include: visualization tools, centralized database, cross discipline platform tools and novel forms of information representation. A case study of an architectural project will serve as the means in which to study the successful implementation of these attributes and their resulting impact on the design process and building project. This study will demonstrate how information technologies can be implemented within the multifaceted framework of conventional building projects to yield a project of unprecedented form.

title Multimodal Spatial Emergence in the Design of Sensate Spaces
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 427-432

summary Design of reactive, intelligent and sensate spaces is a form of spatial design that demands creating thinking in terms of non-permanent, non-tactile and sometimes non-visual media. This implies spatial conceptualization using sensory modalities that are ordinarily of secondary importance to vision in design, such as proprioception and hearing. This paper explores these alternative modalities for both spatial perception and spatial expression with a view to developing innovative interfaces for spatial design. Computer games and installation art environments are analyzed for use of alternative spatial immersion techniques. This informs a physical spatial interaction environment. Motion-capture input and digital auditory output provide real-time, intuitive feedback to the user. Useful interaction strategies are acquired that can be used in a non-intrusive manner in sensate spaces for communal, commercial, or public contexts.

summary This paper presents a pedagogical approach to explore the relationships between time and space by using digital media. Based on a pedagogical model called e-Space proposed by Lai (2004), we apply motion as a spatial issue to approach this study. Through integrating with the characteristics of digital media, students are encouraged to evolve architectural space and form by decomposing, re-organizing, interpreting and realizing the spatial composition. Simultaneously, diverse digital media applications integrated with design thinking in a design process enables students to bridge two design spaces - physical and virtual. This process introduces the students to a new approach of design-creation and form finding. Finally, we use an advanced digital media course as an example to understand the impacts of the pedagogical approach. The students’ outcomes are also reported in this paper

title VIRTUALITY IN ARCHITECTURE: A DESIGN METAPHOR

summary Traditionally, architecture in its design process employs physical matter, requires physical presence and relies on real world environment using conventional methods of 2D depictions such as paper and pen or 3D representations such as physical models and communicates design ideas in verbal or text-based form. The conventional design process, for example an interior design, a residential house, a commercial complex or even urban design projects, follows the same hierarchy of activities. Efforts are made to the satisfaction of both parties to give the ideas of a physical shape through sketches, drafts and models which may take weeks even months. Finally the project gets its final shape in a working drawing, 3D visualisation or model making. This process is time consuming and somewhat redundant. In recent years technology has offered architects a new tool - the virtual environment. Architects use virtual environment increasingly as device of communication and presentation of design intensions. Virtual environment enables users to interact in real-time with design but unfortunately have not been used widely in the process of design development. The aim of this paper is to investigates the relationship between present design process and the emerging technology of virtual reality, establish a relationship between the two and its influence on architecture to form a new translated design process and communication, an interface between architect and client.

title Representational Thickness: a quantitative comparison between physical, CAVE and Panorama environments
source International Journal of Architectural Computing vol. 3 - no. 1, 127-144
summary This study compares aspects of spatial perception in a physical environment and its virtual representations in a CAVE and Panorama. To measure accuracy of spatial perception, users were asked to look at identical objects in the three environments and then locate them and identify their shape on scaled drawings. Results were then statistically compared for differences. In a discussion of the results, the paper addresses three hypothetical assertions – that depth perception in physical reality and its virtual representations in CAVE and Panorama are quantifiably different; that differences are attributable to prior contextual experience of the viewer; and that design professionals and laypeople have different perceptions of what they see in VR. In conclusion, the concept of 'representational thickness' is suggested by the results.

title Simulation of architectural lighting in a virtual environment - A case study on real and fake High Dynamic Range Images (HDRI)
source Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 566-572
doi https://doi.org/10.52842/conf.ecaade.2006.566
summary The early findings of this research were presented in eCAADe 2005 International Conference, Lisbon primarily to highlight the concept of High Dynamic Range Images (HDRI) when representing architectural spaces in the form of still images. An experiment had been carried out to compare the results between HDRI rendering and ‘conventional’ lighting simulation algorithms namely ray tracing and radiosity. The results were based on static and using the same exposure factors, when capturing HDRI. This project, funded by Intensification Research Priority Area (IRPA) grant continues to present and report HDRI results in a simulation environment. In this paper, we first briefly explain on the concept of real and fake HDRI. Then a comparison experiment is conducted to compare these two methods and discuss the impact and effectiveness of the illumination computation in architectural simulation environment. In order to carry out the experiment, a few models of the architectural scenes were developed. These models were then textured with real photos and manipulated with ‘shaders’, and further rendered using fake and real HDRI techniques. As for the fake HDRI, two methods were developed. The first was using an image as the ambient map and different exposures were created by increasing the value of Hue, V of HSV and saturation. The second involved a series of digital photos with the selection of the brightest and darkest area using Adobe Photoshop to establish the scale of luminosity. A few camera movements were triggered and position for ‘real-time’ rendering simulation. The result of the experiment has shown a significant improvement on the rendering time and quality of the rendering. Finally this paper suggests the selection criteria for choosing real and fake HDRI, and how each technique can be best utilized for architectural representations in a simulation environment.

summary Mindstage is a multi-user real-time 3D environment in which is embedded a lecture on film design by Christopher Hobbs. The spatial design follows the structure of the lecture, and is richly illustrated with stills and film clips. The environment, implemented in Virtools, proved to be a visually intriguing combination of architectural, filmic and virtual space, though it was found that co-presence induced some problems with the concept of time.

summary A diversified, open-ended, and critical approach of architectural design that interplays with a variety of media, suggests an innovative development to gain new spatial solutions. Architects and designers are aware of these possibilities by integrating physical and digital media during their design process, yet the creative potentials of these media are rarely used to their full potentials. The architectural design process can be enriched by using uncommon perceptions, comprehensions, and conceptions of spatial design translations within both physical and virtual environments. A wilful interplay with the design media and the process offers the possibility to dismantle the limits of each domain and explore the design itself in unorthodox ways. The overall engagement within both real and virtual environments leads to innovative form creations and powerful design solutions. Following the tradition of artists, who explore media in unusual ways, new architectural interpretations emerge, reflecting on the media as well as the architectural design.

summary It is debatable whether design can be taught. Frank Lloyd Wright himself mentioned that architecture should be taught by its principles, discerning the principles underlying in works by various architects. In the absence of thoroughly satisfactory methods of combining various means of digital representation for analysis, this paper investigates the features of 3D computer models; in particular, its animation environment to aid graphic analysis of built forms. Computer 3D animations, which are generated from 3D models, have an unparalleled capability to demonstrate spatial experience. Animations can also manipulate the constitute components of the spatial structure, thus illustrating analytically the composition of a building or object. The most significant aspect of 3D animation is in its flexibility of manipulation of various physical and rendering attributes of a 3D model. For the purpose of case study analysis, Richard Meier’s Atheneum in New Harmony, Indiana is chosen for its clarity in design elements and demonstration of applicable principles. Through various animation clips, the basic techniques are illustrated as an effective method of communicating concepts of graphic analysis.

summary Today and in the future, architectural students must be prepared for designing both physical and adaptive, computer-integrated spaces. The question is: How do we easily and effectively convey architecturally relevant theories and practices of pervasive computing in teaching? In this paper, we present a didactic model that has proved to be a possible answer. During a semester long design class, we supervised an interdisciplinary group of architecture and computer science students who teamworked on an early so called serious pervasive game prototype, entitled “ETHGame”. The class culminated in a two week compact phase and a presentation before ETH representatives involved in e-learning projects. The resulting interactive prototype takes advantage of our campus’s extensive wireless local area network infrastructure, allowing for user positioning and location based learning, servicing, and peer-to-peer communication. The game mutates the whole of the ETH Zurich campus into a knowledge space, issuing position dependent and position relevant questions to players. The ETHGame forces participants to engage with a given space in the form of a quiz and rewards them for collaborating both face-to-face and facelessly. The game helps them build a collective academic and space aware identity whilst being immersed in a sentient environment. Thus, in this paper we are introducing serious pervasive game design as a novel design research and teaching paradigm for CAAD, as well as a e-learning design strategy.

summary This work is about realizing that human perception is inherent to architecture. It is an asset and a trait subject to training and development in an empirical way, involving physical and manual action. It cannot be taught literally through convention and logic reasoning. It is a human achievement of great significance built on intellectual and scientific knowledge. It is something, being physical and empirical, that is supported on instrumental procedure. The computer, as a machine and an instrument, does not shorten the empirical experience of manipulation; on the contrary, it enhances J.J. Gibson’s findings about the perception of space in relation to eye and body movement. Being a cybernetic machine the computer may, and shall, evolve, and become perceptive. In order for that to happen, it is important to keep in mind the mechanism of human perception. Through producing a computerized model of a major architectural work, we develop natural knowledge about its physical features and the thought that lies underneath. To be able to use the computer as an instrument provides a user with explicit knowledge about its ways and mechanism that has to be made available. It involves training, which is to a great extent self-explanatory, and also explicit knowledge about the conventions that are being used, such as programming, reasoning and trigonometry.

title From Bézier to NURBS: Integrating Material and Digital Techniques through a Plywood Shell

summary The development of digital fabrication has reintroduced material processes with digital processes. There has been much discussion about the tool and the objects of the tool, but little discussion of the implication of the material process on the digital process. A brief historical review on the development of computer numerical control and the origins of the Bézier curve reveals an instrumental fact: computer numerical controlled tools necessitated advancements in computational surfaces which eventually led to NURBS (Non-Uniform Rational B-Splines) surfaces. In other words, the origins of NURBS surfaces resides in its relation to material processes, rather than many current approaches that develop free form surfaces and then force the tool onto the material without regard to the material properties. From this historical and mathematical review, this project develops toward more intelligent construction methods based on the integration of NURBS differential geometry paired with material qualities and processes. Specifically, a digital technique of developing conceptual NURBS geometry into piecewise surface patches are then flattened based on the material thickness and density. From these flattened patches, a material technique is developed to intelligently remove material to allow the rigid flat material to re-develop into physical surface patches. The goal of this research is to develop digital and material techniques toward intelligent construction based on the correspondence between digitally driven surface and digitally driven material processes. The application of this technique as a rational and flexible system is to support the dynamic response of form and material toward such performative aspects as structure, daylight, ventilation, and thermal properties.

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—like other designers—tend 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—in the way architecture is conceived, taught and critiqued—results 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 “movement”, “guiding” and/or “rest” 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.

title Inhabiting the Drawing - 1:1 in time and space

summary One of the fundamental characteristics of architectural drawing is its use of scale. Since the Renaissance - during which architectural production shifted from the construction site to paper - this scalar understanding began by using bodily measurements. In developing designs, the architect projects future occupation of the drawing with their eyes and hands moving over both its physical surface and represented space. The different relationship established between the digital drawer and the body has been criticised; Paul Emmons argues that CAD's full scale - or rather scale-less - capabilities omit this bodily presence of the drawer (Emmons, 2005). Due to the use of full scale data recording, the drawer zooms in and out to consider aspects, severing the drawing's relation to the operator's body. This paper explores ways in which the body and drawings intersect, beyond Emmons definition, and hence considers the influence of the method of drawing on perceptions of scale and the inhabitation of digital drawings. It uses ongoing collaborative research projects and exhibitions to explore the inhabitation of digital drawing at full scale. These works highlight the fundamental importance of the line within architecture, not as demarcation, divider or indexical reference, but as a traces of bodily projections.
