title	Practical Navigation in Virtual Architectural Environments
source	Helsinki University of Technology, Espoo, Finland
summary	The interest towards virtual reality (VR) and virtual environments (VE) is growing all the time. The applications being developed for VE run a wide spectrum, from games to business planning. This thesis concentrates on navigation in virtual architectural environments, movement in worlds that are very similar to our own. Navigation in a virtual world should be practical, intuitive and simple. Unfortunately, it is very often far from that - for some reason the usability issues in VEs have been usually left with little attention. Currently it is easy for a user to get lost and disoriented when traveling in a VE. This situation must change, navigating through virtual environments can no longer be considered a task reserved for the experts only. 3D-worlds and architectural applications for the common user require new, intuitive interface techniques. This thesis addresses issues related to both physical and cognitive aspects of navigation as well as theoretical models that bind them together. In the technology survey of this thesis, the virtual environment technology is presented. Different visual display systems, new input devices and some 3D user interface design aspects are described. The literature survey section discusses the main issues concerning navigation theory. The two parts of navigation, travel and wayfinding, are described in detail. The major challenges are discussed and some solutions and various research results are presented. A major part of the thesis consists of the description of HCNav, a new navigation system developed by the author. The system was constructed for use in the virtual room at Helsinki University of Technology. The purpose of HCNav is to provide a very intuitive and practical navigation interface. Three new experimental input devices, namely custom wand, data glove and speech recognition system, were tested. Another important part of the work is to evaluate the effectiveness of the HCNav system. A usability test was conducted to determine if the use of HCNav was actually improving navigation performance. Twelve subjects participated in a test where HCNav was compared with a traditional navigation software used previously in the virtual room. The experiment setup has been described and the results analyzed. The results are promising and show that the navigation methods adopted in HCNav are clearly better.

summary	The paper is an inclusive summary of research work on creating VR city models carried out over the last six years in the UK and Greece aiming to put into discussion the guidelines/ rules developed by the author. The paper is structured in three sections referring to the main stages in terms of either technical expertise and problem solving or conceptual structuring of information: creation of 3D city models, CAAD versus VR in digital city modelling and finally utilizing digital city models. The expected outcome of the work presented is the establishment of a body of knowledge that will facilitate the development of standards and guidelines for the creation of city models. There are obvious advantages in having a compatible set of city 3D models. On the other hand, there are different rules to be followed and issues to be solved, according to the scale of the model, level of detail that is needed—all these rules relate to the projected use of the model.

title	Virtual Exhibitions: How to put the gallery on-line?
source	International Conference on Generative Art
summary	This research is part of a project I developed at York University and realized at the Walter Phillips Gallery at Banff Centre for the Arts. It originated from a preliminary survey on the galleries and museum’s approach to the web: how did these institutions engage with the virtualspace? What tools did they employ to display their content? How did they exploit internet in order to promote and advertise their content and transmit a certain message? Following the examination of several interfaces and modes of display, a list of recurrent strategies, needs andlacks was compiled. A further development of the research consisted in a practical attempt to include all the characteristics observed and to add the elements supposedly missing in a single project. The project examined two distinct and very different exhibitions which took place during the summerat the Walter Phillips Gallery in Banff: they were analysed, documented and rendered on-line using a popular animation software such as Flash.

summary	Building activity in Germany is moving increasingly toward combined newbuild and renovation projects. Essential for effective computer-aided planning within an existing context is not only the use of on-site computer-aided measurement tools but also an integrative cooperation between the different disciplines involved via an information and communication system. Interdisciplinary cooperation needs to be tailored to the integrative aspects in renovation and revitalisation work. Economic factors determine the viability of an architectural project, and reliable costing information is vital. Existing IT-approaches to this problem are not yet sufficiently exploited. In ongoing research at our university (collaborative research center ”Materials and Structure in the Revitalisation of Buildings”) methods and techniques of revitalisation are being investigated. A special branch of the collaborative research center is investigating possibilities of computer-aided building measurement and communication platforms for professional disciplines (www.uni-weimar.de/sfb). The aim is to develop a general approach to the revitalisation of buildings. This paper discusses possible application areas of AR/VR techniques in the revitalisation of buildings from the point of view of the user and are based on the real project “Cooling factory Gera”. Based on the necessities of revitalisation projects, technical requirements are developed. The project is funded by the Deutsche Forschungsgesellschaft (DFG).

summary	To make whole one image on screens that is generated by many computers and synchronization among computers, there is a need for a network software environment for multi-projector display system. Although the development costs increase for parallel programming for multi-projector display system, there is a possibility that the program cannot be executed at an enough speed since the network bandwidth might become a bottleneck. There are some software environments for that kind of multi-projector display system like Chromium that is latest version of WireGL (Humphreys, 2001&2002). WireGL is a kind of Client-Server Model, which one rendering server sends the data of rendering to many computers. While it can use the application without modification of source, it requires heavy network traffics. The other type of operating software is VR Juggler (Cruz-Neira, 2002), and CAVE Library that is a kind of Master-Slave Model. In the Master-Slave Model, every computer has same application programs to render the image that only keep the synchronization of rendering and events. But, these programs require a specialized skill and knowledge to modify the source of program for the certain rendering PC-Cluster system.

title	XML for Flexibility an Extensibility of Design Information Models
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

title	Abstract but Tangible, Complex but Manageable
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the VR-DIS research program, an innovative design-information modelling technique has been proposed that is based on features. In this modelling technique, the designer is invited not only to model the form and spatial aspects of his or her design, but also to model the structure of the data behind the design. The designer is offered a way to control how abstract design data is structured and stored. In this way, the designer is given the power to model concepts like conformity, contrast, and scale on the formal data level, and this for both graphical and non-graphical design characteristics. Further, the designer is invited to input formal descriptions of own design concepts, and use these personal concepts during the design process. With this new information modelling technique, we expect that the designers will be better capable to handle the complexity of linking diverse kinds of information involved in a design process. This new way of computer aided design offers a unique design freedom: any design concept becomes addressable. On the other hand, this technique also puts the responsibility for the content of the CAD database entirely in the hands of the designer. In order to be able to enjoy the design freedom fully and at the same time handle the responsibility over the design database, a computer tool is needed that shows the precise content of the database, and that is easy and quick to interact with. Only with such a tool, the designer will be capable of keeping the complex data model in pace with his or her design reasoning. To realise this requirement, a “feature browser” has been developed with a 3D graphical user interface. It shows the data objects as 3D blocks, mutually linked by rubber-band arrows that closely reflect the database structure. The whole forms an interactive 3D graph. The intuitiveness and user friendliness of the interface was improved by adding features like the visualisation of the browsing history, the visualisation of link-semantics, and animated visual feedback effects. The hardware part of the interface is worked out as a Fish Tank VR set-up. This hardware configuration improves the experienced realism of the displayed 3D objects up to a feeling of physical presence. The interface as a whole therefore provides a highly attractive display of the abstract design data; abstract but tangible. It is a tool in which complex data structures can be explored and controlled: complex but manageable.

title	Virtual and full-scale modeling: A collection of resources

summary	In this paper the relationship between Virtual and Full-scale Mo-deling will be traced back. A number of publications supports the dis-semination of existing knowledge resp. experiences. Although a series of biannual EFA-Conferences (European Full-scale Modeling Association) produced a remarkable number of useful papers, the "scientific output" beyond this platform remained to be so far in the dust of gray literature. On the other hand the rapid growing interest for computer applications and tools rediscovered the working area of 1:1 simulation more or less the other way around. Although the term VR in the nineties was strongly occupied by computer-interfaces resp. -representations, soon the insight gained in importance that reality is by far more complex than some 10.000 polygons. Furthermore, some kind of unproductive competition resp. defense of good old modeling tra-ditions versus promising computer technology seemed to act as the main activity. However, the fusion of Virtual and Full-Scale Mo-de-ling could indefinitely serve as a promising field of research.

title	Visual Cues in the CYBER-REAL Complex
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	Current Computer Aided Architectural Design deals with issues of complexity in creation and interpretation of the built environment, complexity of the computer systems and complexity of the representations of the design object. The term ‘CYBER-REAL Complex’ in this paper is defined as the whole (un)conscious state of the architectural design project in the heads of the design-group and as how it is maintained in CAAD systems. The ‘CYBER-REAL Complex’ contains the design, its context and all related information such as planning, product specifications and design ideas. An Intranet is an interesting means for storage and approach of such complex project-data. However the knowledge and data of the project participants remains in their heads and new methods have to be developed in order to get each participant to share his or her personal information about the project. Meetings and intense data retrieval by an Intranet can establish a useful ‘CYBER-REAL Complex’. Then, as a designer wants to approach and change the information in the ‘CYBER-REAL Complex’, a very good set of tools, methods and media has to be at hand. The complexity of all the information can be overwhelming and it can take much effort to re-understand and re-interpret the information before new decisions and design-steps can be made. Currently, the understanding of CAAD representations by the designer and the deliberate execution of operations on increasingly complex datasets through increasingly complex user interfaces takes too much time and effort. An enhanced way of representation in the ‘CYBER-REAL Complex’ could help the approach and understanding of the information. Therefore the visual language of information systems needs further research and development. This paper explores several limits of human perception and ways to adhere to the human way of visual thinking in order to find and add new visual cues in CAAD, VR interfaces and in the ‘CYBER-REAL Complex’ as a whole. Successively the perceptive aspects of complex information, the role of visual cues in complex information and several examples of visual cues in research tests are presented. The paper draws from knowledge of the Gestalt Theory, Perception Research and findings of a PhD research project about Visual Language for Context Related Architectural Design. Findings of this research show that designers use distinct views to get overview and insight in the project data and that different kinds of data representation are needed for different phases in the design process. Finally it showed that abstract represented and filtered information can be very useful for remaining focus in the otherwise overwhelming dataset.

title	Virtual Environments for Special Needs. Changing the VR Paradigm
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 151-159
summary	The normal application of Virtual Reality is to the simulation of environments, which are in some way special - remote, hazardous or purely imaginary. This paper describes research and development work which changes the paradigm by simulating perfectly ordinary buildings for special people. Some 15% of the population have some form of physical impairment - a proportion which is likely to rise in line with an ageing population. New legislation, such as the UK Disability Discrimination Act places additional responsibility on building owners to ensure adequate access for people with an impairment and this in turn will place additional responsibility on the architect. Current methods of auditing access for new building are primitive and require the auditor to interpret plans/sections of the proposed building against a checklist of requirements specific to the special need. This paper reports on progress in the use of an immersive VR facility to simulate access to buildings for two broad classes of user: i) those with a mobility impairment; ii) those with visual impairment. In the former case, a wheelchair motion platform has been designed which allows the wheelchair user to navigate the virtual building; a brake and motor connected to the rollers on which the wheelchair sits facilitate the effects of slope and surface resistance. In the latter case, the main categories and degrees of visual impairment can be simulated allowing architects to assess the contribution of form, colour and signage to safe access.

title	Exploiting Tools of Evaluation to Improve CAAD Teaching Methods. A Case Study of Inter & Intra ECTM Model
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 215-230
summary	This paper reports on an ongoing research study model into the Evaluation of CAAD Teaching Methods (ECTM) of which a number of resolutions and strategies were attained via an empirical investigation. The first stage of the study findings proposed a framework for the evaluation of architecture courses in tandem with CAAD. The second stage was based on the Inter & Intra ECTM design model as a strategy for acquiring solutions to CAAD problems through the exploitation of CAAD evaluation tools. The ECTM model structure criteria: the Model Concepts, the Operational Context, Dialectic Meanings, Relational Context, Performing Methods and Level of Integration were illuminated. ECTM model has a twofold involvement junctures, which describe CAAD evaluation behaviour. The first involves the evaluator in an interdepartmental comparison of CAAD integration into the curriculum, and/or between schools of architecture. The second engages the evaluator in an intradepartmental study of CAAD integration, and within the institution. The study projected an attempt to validate the Inter & Intra ECTM design model in concert with evaluation. The paper presents an extended description of the objectives, procedures and testing designed for the two abovementioned junctures composing the proposed ECTM case studies. Sequences of methods of data collection employed as a vehicle for the ECTM were Kirkpatrick model, questionnaire survey, observation (using an ECTM checklist) and experimental studies. The paper also explores variables and indicators used, and advances to shed some light on the methods of statistical analysis employment. ECTM model as a tool to attain CAAD effectiveness might redefine the role of collaborators/ team partnerships in CAAD tuition; and induce the level of technology selection and adaptation amongst schools, e.g. tutors and coursework interconnectivity. The ECTM model may also work as a framework of strategies to augment interactivity and positive learning amongst both staff and students.

title	Preparing a multimedia-based gallery for institute of higher learning: A case study of Malaysian experience
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 305-316
summary	While the majority of medium and small sized institutions still rely on their physical or traditional content, it has been observed a pre-disposition usually by major, recently founded or contemporary art institutions to display net-based projects (Buiani, 2001) and to some extent established as a permanent display. This changing of exhibitions has penetrated in many Asian galleries and as a result many schools trying to re-position and present in such a way that it can be easily changed and adapted to host multimedia, Internet, interactive and computer-based content. This funded research project investigates the functions of gallery in IHL in Malaysia. A triangulated study was conducted to understand the potentials and issues faced by galleries in public and private universities focusing on design schools that include art and design, and architecture. This research starts with the understanding of gallery design theories. It is then followed by a qualitative method survey to all galleries in the IHL. This research continues with an in depth study and a survey on Electronic Gallery (e-Gallery), Faculty of Creative Multimedia (FCM), Multimedia University (MMU) to understand between the theories and design ideas. A set of questionnaires was developed based on Mathews (1991) and Stewart’s (2002) principles and guidelines on research methods and distributed to visitors throughout a period of time consisting of open-ended, close-ended, Likert Summated Rating Scale and Multiple-choice. This involved a controlled group of visitors comprises students and staff of the faculty. The results of these studies will be used as a reference to further conduct a wider scope of galleries worldwide towards designing a multimedia-based gallery framework for Institute of Higher Learning.

title	Discussing Image-Based Modeling Technology for 3D Digital Archival of Physical Architecture Models

summary	Besides drawings, physical models are important forms of representation commonly used for architectural design. They can serve as a useful resource for teaching and research, provided there is a proper archiving system that allows easy retrieval. Architectural models in 3D digital format seem to be able to overcome the limitation of physical constraints – they can be easily accessed anytime and anywhere over the Internet. The most common way of 3D model documentation is through geometric-based 3D CAD software. Image-based modeling (IM) allows the 3D digital model to be created from photographic images. Debevec (1998) investigated the hybrid geometry- and image-based approach whilst Tsou (2002) and Hawkins (2001) focused on the application of IM for GIS and digitizing cultural artifacts respectively. This paper aims to compare physical models and their IM counterparts in terms of communication of vital architectural information. Experiments were conducted to evaluate the extent the IM model resembled the physical predecessor in terms of its geometry and visual appearance qualities/faithfulness. A survey was subsequently carried out to compare their performance in terms of the communication of vital architectural information about building designs to the observers. The tabulated results were then examined to help understand the opportunities and weakness of IM for 3D archival of physical architecture models

summary	For several years we have been using the metaphor of play to conceive and deliver our design teaching. We report here results of a qualitative evaluation study on the effectiveness of our approach. We used both a participant observer methodology and a formal survey to gather and interpret data from the classroom. The results show tentative support for a positive role for play in early design education and several insights into how to build play into the design classroom.

summary	The internet is becoming increasingly more valuable in the field of architectural design that what we conventionally called CAD might soon be changed to iAD (internet Aided Design) (Zhou and Krawczyk 2000). In order to have a clear vision of what iAD will be or could be, we should first examine what is currently available. This research focuses on an investigation of selected web vendors, which are typical and most influential in providing internet related services for the AEC industry. Our purpose for doing this survey is: to understand the progress and development of internet application in the AEC industry, identify the technology used in this area, determine the advantages and deficiencies of current practice and develop a base for future research in proposing a evolutionary model of internet Aided Design for architecture.
