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

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

title	Three-Dimensional Shape Generation of Low-Energy Architectural Solutions using Pareto Genetic Algorithms
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 647-654

summary	This paper extends on a previous work on the application of a Generative Design System [GDS] to the evolution, in a computational environment, of three-dimensional architectural solutions that are energy-efficient and adapted to the climatic environment where they are located. The GDS combines a well-known building energy simulation software [DOE2.1E] with search procedures based on Genetic Algorithms and on Pareto optimization techniques, successfully allowing to tackle complex multi-objective problems. In the experiments described, architectural solutions based on a simplified layout were generated in response to two often-conflicting requirements: improving the use of daylighting in the space, while controlling the amount of energy loss through the building fabric. The choice of a cold climate like Chicago provided an adequate framework for studying the role of these opposing forces in architectural form generation. Analysis of results shows that building characteristics that originate successful solutions extend further than the building envelope. Issues of massing, aspect ratio, surface-to-volume ratio, orientation, and others, emerge from the analysis of solutions generated by the GDS, playing a significant role in dictating whether a given architectural form will prove adapted to its climatic and energy requirements. Results suggest that the questions raised by the exploration of form generation driven by environmental concerns are complex, deserving the pursuit of further experiments, in order to better understand the interaction of variables that the evolutionary process congregates.

title	Improving Design using Autonomous Spatial and Structural Generators
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 743-750
doi	https://doi.org/10.52842/conf.ecaade.2005.743
summary	During a building design process, a structural designer transforms a spatial design into a structural design and this structural system can be improved by optimisation methods or expert views of other structural designers. The improved structural system allows the architect a new spatial design, which can be transformed or altered again by the architect. This design cycle can be repeated several times and is defined as interaction of spatial and structural design. Case studies are used to demonstrate that this interaction occurs in practice and is needed to improve building quality. This paper presents a program with more or less autonomous spatial and structural generators. Each generator will facilitate one direction in the interaction process. Then using both consecutively leads to a design method that provides interaction between spatial and structural design. For the spatial generator, named “room positioning with structural constraints” a space allocation technique is used including constraints that handle structural boundary conditions. A zone generator based on pattern recognition and shape grammars handle the structural design. A Prolog-2 program was developed to demonstrate the application of the two proposed generators. “Zone generation” is performed per building storey and thus represents a horizontal two-dimensional procedure. Similarly “room positioning with structural constraints” is a planar vertical operation. In future these procedures can be made three-dimensional.

title	GENERATIVE INTERFACES AND SCENARIOS - INTERACTION IN INTELLIGENT ARCHITECTURE
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 107-113

summary	New media and modern building automation have a strong impact on contemporary architecture. So far one could regard built architecture as static. These new technologies introduce a dynamic impulse to architecture. The objective of our research and teaching work is to demonstrate the impact of innovative systems on architecture in daily usage while providing building automation, multimedia integration and facility management services in intelligent networked buildings. These technologies, as described in this paper are integrated in our second year course for students of Architecture. By designing an interactive graphical interface for the lab they were asked to create a spatial scenario as a self running Flash animation. Thus real space is merged with virtual reality.

title	Infilling Time into Space - A Pedagogical Approach for Evolving Space Using Digital Media
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 147-154

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

summary	Planning workshops are known to provide important opportunities for citizen’s participation in environmental planning. The digital camera is a convenient tool for such workshops though participants still face difficulties in smooth sharing of information amongst themselves. The authors developed a prototype system for a planning workshop that applies the web-GIS technique, and devised techniques for the system-applied planning workshop through a case study. This paper discusses, first, an assumed procedure for place studies at a planning workshop; second, the functional features of the developed system; third, arrangements for the environment of the workshop; fourth, an experiment of the system use with an urban design workshop in which 91 students participated, forming 16 teams; and finally, assessment of the operational ability of the prototype and necessary refinements for in the next version.

title	A Representation Language for a Prototype CAD Tool for Intelligent Rooms

doi	https://doi.org/10.52842/conf.acadia.2005.170
summary	Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

summary	This paper reports on a study of the role of place in a virtual learning environment for digital media design. Using an immersive 3D Virtual World based on Active Worlds, we have created a virtual learning place for students in a Website Design course. The virtual learning place has two distinct parts: a classroom-like place surrounded by student galleries. Students can navigate and communicate (synchronous chat) within the environment in the form of an avatar (virtual person). We recorded the conversations and activities of the students in discussions held in the virtual learning place and applied a communication coding scheme to analyze their discussions. In this paper we present our approach to developing an understanding of the role of place and evidence of its effect on the conversations of design students in a virtual learning environment. We show how we identified the characteristics of place and specifically how it provides a context for identity and presence for supporting collaborative and constructivist student centred learning.

title	DESKTOP VIRTUAL ENVIRONMENTS IN CONSTRUCTION EDUCATION
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 725-730
summary	In construction science, classroom oriented education remains the preferred mode of teaching. Alternative methods such as field trips, use of 3D drawings, and physical models often supplement and enhance the understanding of students. In addition to the risks involved with field trips, designated sites may not be at the particular stage of construction during the academic semester, or the construction sequence may not be fast enough to demonstrate the multiple facets during field visits. Considerable pedagogical advantages can be achieved by the integration of IT and visualization tools in teaching construction engineering/technology. The objective of this research was to develop a desktop virtual environment using 3D, animations, virtual reality and walkthrough of construction processes of steel, concrete, and lightwood structures. These visualization techniques can be valuable aids not only in teaching in the classroom but also an effective self-directed tool for open learning via the web.

title	VIRTUALITY IN ARCHITECTURE: A DESIGN METAPHOR
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 1, pp. 342-350
doi	https://doi.org/10.52842/conf.caadria.2005.342
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	Comparative Navigation System for Collaborative Architectural Design
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 293-299
summary	As information technology continues to evolve, it is affecting all creative art forms by providing new tools and surroundings, such as virtual environments. 3D real-time simulation environments strongly support communication and navigation, enabling users to collaborate on designs using centralized or distributed environments. The persons concerned must understand the proposed design. Systems that help them gain this understanding are therefore required. An effective concept for gaining understanding is comparison. However, comparing one design proposal with another using existing systems is difficult because the users must consider their viewpoints separately. In this paper, we describe the concepts, strategies, and functions of a 3D virtual design environment for collaborative, real-time architectural design that is based on our 3D comparative navigation system and real-time simulation technology. We also evaluate the advantages and disadvantages of using this design environment to support collaborative architectural design.

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.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 338-343
summary	This work deals with the process of exploiting the potentialities of Open Source software to promote distance learning of Digital Graphics. It is considered that this modality of study should offer flexibility in terms of software choices. The GRAFICA LIVRE group emerges with an interdisciplinary character to establish collaborative space of work between students and lecturers from Computer Science Course and Digital Graphics Post-Graduation Course. The hypothesis of this study refers to the possibility of identification and development of procedures to create virtual environments using open source software. The activities defined lead to the implementation of three-dimensional multi-user environment based on open source software in both senses, used to the construction of the environment and to the development of activities to distance learning on Digital Graphics. This paper describes the methodology to structure didactic material to be accessed remotely focusing on identification and enhancement of tools to develop specific activities.

summary	There have been many successful examples of Virtual Design Studio projects that have used a variety of network communication technologies, showing that interaction among participants enhances performance of the design team. However, the application of VDS techniques to a design studio program conventionally conducted in a studio space still seems to be limited, even though there is a clear need to improve interactions among students and teaching staff. The authors developed web-based groupware, GW-Notebook, and application techniques for a design studio program to enhance interaction in class hours in a studio space and also in off-studio hours, in which members work in separate locations. This paper discusses a model of communication and interaction in a collaborative design studio program conducted in a studio space. It also considers the major features of the developed system, the environment, and method of system usage in different teaching styles, and finally reviews performances of the latest system tested at junior collaborative design studio.

title	Townscaping: Development of Dynamic Virtual City Augmented 3D Sketch Design Tools
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 105-114
summary	The paper presents the development of an experimental Web-based design environment called Townscaping to be used at the conceptual stage of architectural and urban design. Inspired by Gordon Cullen's seminal work on Townscape (1960's-1970's), the idea of Townscaping is to explore how 3D digital sketch design tools could be developed to operate in connection with a dynamic virtual city system under a user's direct control. A prototype of Townscaping has been designed and implemented on the basis of an existing dynamic virtual city system. In Townscaping, a set of tools is provided for users to create and edit 3D graphic elements to be positioned directly onto the user-specified virtual city models. One of the key features of Townscaping is to enable sketching while navigation: designers can perform sketch design and gain immediate visual feedback while navigating the 3D virtual city models to any viewpoint at any moment. The current study suggests that it is feasible for virtual city models to serve as interactive urban contexts for 3D sketch design. Townscaping is considered primarily a research platform with which we are interested in investigating if designers' engaging in 3D space conceptions may be enhanced through interacting and sketching with virtual townscapes.

title	Design Innovation through Constraint Modeling
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 671-678

summary	This paper describes how constraint modeling can support design innovation. Furthermore, it lays out how constraints are employed in the construction and exploration of a model’s design space. The paper places this approach within the larger context of design exploration using computational and conceptual representations of design. Four general constraint types are identified and examples from several workshops and design studios are presented for each of the constraint types. The examples range from product design to structural design to fabrication issues in architecture. Based on a review of the literature the most common constraints are of geometric, topologic, functional, and quantitative type. Based on the case studies the paper describes how the different types of constraints can be used as design drivers and help in the exploration of solution space. In conclusion the paper identifies the addition of bi-directional properties to constraint modeling as the next challenge in improving the application of constraint modeling in design exploration. Furthermore, the paper demonstrates the necessity to develop better constraint models for cross domain design.

title	Architecture as the Computer Interface: 4D Gestural Interaction with Socio-Spatial Sonification
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 763-770

summary	Architecture today extends far beyond designing building shells and material, peripheral boundaries. Arguably, it has always been, and shifts increasingly in contemporary environments towards, designing space and interaction with space. Hence, the role of the designer includes integration of computing in architecture through ambient display and non-tactile interaction. This paper explores a framework in which the architecture is the computer interface to information sonification. (Sonification is automatically generated representation of information using sound). The examples in this paper are Emergent Energies, demonstrating a socio-spatially responsive generative design in a sensate environment enabled by pressure mats; Sensor-Cow using wireless gesture controllers to sonify motion; and Sonic Kung Fu which is an interactive sound sculpture facilitated by video colour-tracking. The method in this paper connects current information sonification methodologies with gesture controller capabilities to complete a cycle in which gestural, non-tactile control permutes and interacts with automatically-generated information sonification. Gestural pervasive computing negotiates space and computer interaction without conventional interfaces (keyboard/mouse) thus freeing the user to monitor or display information with full mobility, without fixed or expensive devices. Integral computing, a blurring of human-machine boundaries and embedding communication infrastructure, ambient display and interaction in the fabric of architecture are the objectives of this re-thinking.
