Key-note Talks

Key-note Talk 1: Cyberworld Modeling: Integrating Cyberworlds, the Real World and Conceptual Worlds
by Tosiyasu L. Kunii, Kanazawa Institute of Technology 

The globalization of the real world we live in has been almost exploding in its speed and scale in all the key aspects including business, economy, industry, education and culture, making it hard for human beings to cognize what's going on. Thus the links between the real world and conceptual world is getting weaker. The globalization is mainly driven by the Web-based activities in their cyberspaces creating cyberworlds as seen in e-business, e-commerce, e-manufacturing, and cultural heritages through the Web and on the Web. Thus the links between the real world and cyberworlds are becoming ever tighter nonlinearly in time and space. It is now crucial to find a way to automatically integrate the dynamically changing worlds, namely the real world, cyberworlds and conceptual worlds, fast enough. It is a hard task owing to the vast complexity of the worlds to be integrated, and it requires an advanced abstraction modeling. This talk is an interim progress report on it, presenting the outline based on the previous works on the abstraction hierarchy modeling of cyberworlds, imposing minimal cover generation at each level of the abstraction as a new and realistic method, and utilizing available high speed computation such as grid computing. The design issues of the modeling are also discussed.

Tosiyasu L. Kunii is currently Director of IT Institute and Professor at the Department of Computer and Information Engineering, Graduate School of Engineering, Kanazawa Institute of Technology. Before that, he was Professor at Hosei University. He is also Honorary Visiting Professor of University of Bradford, and Professor Emeritus of the University of Tokyo and of the University of Aizu of which he was the Founding President from 1993 to 1997. He received his B.Sc. in 1962, M.Sc. in 1964 and D.Sc. in 1967, all from the University of Tokyo. He had been Professor at the Department of Computer and Information Science at the University of Tokyo from June 1978 until March 1993. He has also contracted both academic and commercial licenses with Bell Laboratories. He received the 1998 Taylor L. Booth Education Award from the IEEE Computer Society, the highest educational award of IEEE Computer Society which is given to one individual annually. In January 1991 he was elected Fellow of IEEE for his contribution to visual computer and visual computation. He was also elected Fellow of the Information Processing Society of Japan (IPSJ) for ‘International Contributions to Pioneering in and Establishing the Discipline of Visual Computing’, March 14, 2000. He authored and edited around 50 books in computer science and in general areas, and published over 300 refereed original academic/technical papers in computer science and applications.

Key-note Talk 3: Combining the Real and Cyber worlds using Mixed Reality and Human Centered Media
by Adrian David Cheok, Nanyang Technological University

This talk outlines new facilities within ubiquitous human media spaces supporting embodied interaction between humans and computation, both socially and physically, in both the real world and cyber world. The research has the aim of developing novel interactive computer work and entertainment. We believe that the current approach to developing electronic based entertainment environments is somewhat lacking with regard to support for multi-person multi-modal interactions. In this talk, we present an alternative ubiquitous computing environment based on an integrated design of real and virtual worlds. We discuss some different research prototype systems: the Virtual Kyoto Garden, Touchy Internet, Tilt-Pad, Magic Land, and the Human Pacman. The functional capabilities implemented in these systems include spatially-aware 3D navigation, tangible interaction, and ubiquitous human media spaces. Some of its details, benefits, and issues regarding design support are discussed.

Adrian David Cheok is Director of the Interaction and Entertainment Research Center at NTU. He is also Associate Professor in both the School of Computer Engineering and School of Art, Design, and Media. He has previously worked in real-time systems, soft computing, and embedded computing in Mitsubishi Electric Research Labs, Osaka, Japan, and NUS. He has been working on research covering mixed reality, human-computer interaction, wearable computers and smart spaces, fuzzy systems, embedded systems, power electronics, and multi-modal recognition. He leads a team of over 20 researchers and students. He was IEEE Singapore Section Chairman 2003, and is presently ACM SIGCHI Chapter President. He was awarded the Hitachi Fellowship 2003, the
A-Star Young Scientist of the Year Award 2003, and the SCS Singapore Young Professional of the Year Award 2004.

SUN Microsystems Inc., Mr. T. Mohandoss
Changing Trends in Computing - Distributed Clusters & Horizontal Scaling

Computing is undergoing rapid changes. First the architecture changes in technical computing workloads. The need to build faster and cost effective infrastructure have pushed the technical computing architecture to 'shared nothing clusters'. How better the architectures of Opteron Processor and InfiniBand Interconnect are making impact as a case in point is suggested.
   In Business computing the shift from client/server to web centric computing model and the rise of J2EE and .NET are giving option to scale horizontally. Oracle, MS SQL server and IBM DB/2 are also pushing the architecture toward Grid databases or clustered DB.
    The third area is virtualization. In Technical computing workloads Grid has gained ground but now Virtualization is also making its presence felt in business computing workloads.

T.Mohandoss is Director - Volume Solutions, Asia South Sun Microsystems. He is with Sun for more than 10 years in Sales, Product Management,  and Industry Business Development.  Mohan has total of 19 years experience in IT and he is a mechanical engineer with an MBA degree.

GraphicsJungle Research Group, Computer Science Department, University of Calgary, Canada
by Brian Wyvill

In the last 20 years there has been much research into the implicit modeling metaphor, however these techniques are little used in games or commercial animation. The traditional view is that these models are slow to visualize and are restricted to cartoon-like models that cannot be textured. In fact recent work has produced engineering models using CSG, shape control using space warping, detection of contact, animation constraints, and non-photorealistic rendering, all using implicit techniques. Moreover the use of spatial caching and tree pruning has made possible real time interaction. The BlobTree encapsulates these advances and has also been used in a sketch-based system that produces a 3D implicit surface from a few strokes drawn by a designer and textured in real time. In this talk the underlying methodology of the BlobTree is presented along with some of the latest results for modeling highly complex models, such as realistic bio-logical trees, and a new parameterization technique for texture mapping sketch-based implicit surfaces.

Brian Wyvill is a full professor at the University of Calgary, Computer Science department. He received his PhD from the University of Bradford in 1975 and continued his interest in computer animation as a research fellow at the Royal College of Art. After working as a consultant for various animation projects including some scenes from the film 'Alien', he joined the University Calgary faculty in 1981. At Calgary he built up the GraphicsJungle research group and there are now five faculty and about 30 graduate students in the group. In the implicit modeling field, Brian, together with his brother, Geoff Wyvill, have contributed fundamental algorithms such as the first implicit surface polygonizer and more recently the BlobTree data structure and associated algorithms, in which many complex models have been built. Current research interests include implicit modeling, non-photo realistic rendering and sketch based modeling. He is a member of Eurographics, ACM, CGS, and editorial boards of the Visual Computer, Journal of Computer Animation and Virtual Worlds, and the Journal of Shape Modeling. Recently Brian was elected to the Eurographics executive committee.
