Invited Talks

IT1: Cyberworlds as the Leading Power of World Evolution
       Tosiyasu L. Kuni
       3 December, 9:00-10:00

This paper solely serves as an initial summary of algebraic topological resources for studying cyberworlds starting from the very elementary set theoretical level. High social impact application cases of e-financing and e-manufacturing are presented at the end.

IT2: Believable Cyberpeople: A True Challenge for the Decade
       Daniel Thalmann
       4 December. 9:00-10:00

We define cyberpeople as people represented on the net using embodiment. These people can be either avatars that are a representation of a real human or completely synthesized virtual humans or embodied agents. In this paper, we discuss the two kinds of cyberpeople and show how it will become difficult in the near future to distinguish avatars from embodied agents. We will demonstrate with examples how embodied agents become more and more intelligent and autonomous.

IT3: This Year in the MOVES Institute
       Michael Zyda
       5 December, 9:00-10:00

The MOVES Institute’s mission is research, application and education in the grand challenges of modeling, virtual environments and simulation (MOVES). The institute’s focus is on 3D visual simulation, networked virtual environments, computer-generated autonomy, human performance engineering, immersive technologies, defense/entertainment collaboration, and combat modeling and analysis. In this talk, we discuss our research vision, and specific projects within that vision.


3 December

T1: Cybersurgery
      Wolfgang Mueller-Wittig, CAMTECH, Singapore

This tutorial is an introduction to the field of using new enabling technologies in medicine focusing on surgical training. It addresses individuals new to the field or those interested in innovative technologies. Moreover, this tutorial will help the surgeon move into the world of virtual surgery. A survey of current use of new technologies in medicine is provided. Possibilities and research challenges in using state-of-the-art medical simulators will be highlighted.

T2: From Macys to Mars, Virtual Environments in Vertical Applications
      Bruce Damer, The Digital Space Commons, USA

This tutorial will cover the commercial and educational use of virtual environments from industrial simulations for NASA to collaborative learning to fashion design. A history of the virtual environments field will be given to set today's context where we see some successful application of the medium. Detailed implementations of some vertical applications built using the new Adobe Atmosphere platform will be provided.

T3: Dancing In Cyberworlds:  Real Medicine, Realtime Art 
      Galen Brandt, The Digital Space Commons, USA

This tutorial focuses on both artistic and medical uses of cyberworlds, and considers them as two faces of the same practice.  We will examine VR as an effective treatment for psychological, perceptual, behavioral and biological disorders, from autism to ADD, phobias to PTSD to Parkinson's Disease.  We will look at VR also as an artistic medium, from classic practitioners to cutting-edge projects, self-constructing art galleries to 3D fashion-spaces, interactive installations to real-time avatar performances.  All involve artful collaborations with machines that re-link mind and body, rethink medicine, re-humanize self and reanimate space.

T4: Effective Strategies in Introducing Synchronous Communication Tool
       Alan Soong, Centre for Educational Development, NTU, Singapore

The tutorial session will provide participants a framework which has been adopted in fostering a flexible learning environment in NTU. Participants will also have an opportunity to experience the various tools which supports flexible delivery. Technical aspects/considerations in implementing flexible delivery will also be discussed.

Industrial Presentations and Exhibitions

4 December

IP1: Silicon Graphics Pte Ltd.
Talk by Dr. John Kan and exhibition

Accelerating workflow with Visual Area Networking
The vision of Visual Area Networking is to enable universal access to advanced visualization using any computing device, over standard networks.
     Visual Area Networking is the SGI vision of providing universal access to advanced visualization--to any user with any client device located anywhere in the world. Using the SGI graphics server as its core, Visual Area Networking enables remote access to the graphics, compute and I/O power of a visualization supercomputer and multi-user collaborative access to that power using existing network and desktop resources  as well as wireless devices.
     The concept of Visual Area Networking represents a shift from focusing only on advancing pure rendering power to include consideration of the location and availability of visualized data sets across the network. Visual Area Networking makes rendered data available to the user by sending only the pixels of the visualized graphic, rather than the raw data, to be visualized locally. As such, it protects the integrity of the data being visualized by eliminating redundant copies and version control problems, as well as limiting unauthorized access.

IP2: Hewlett-Packard Company 
Talk by
Mr. Mark Manners and exhibition

Cool Web services for the Cyber World
People are nomadic. They move around to work, to shop, or to play. Increasingly the places they enter are computerized. Their workplaces are filled with computers; the stores they browse are computerized; the toys they buy are computerized. And communications networks reach into every corner.
     In Cooltown, technology transforms human experience from consumer lifestyles to business processes by enabling mobility. Cooltown is infused with the energy of the online world, and web-based appliances and e-services give you what you need when and where you need it for work, play, life. 
     Most of our work at Cooltown has focused on extending Web services  technology, wireless networks, and portable devices to create a virtual bridge between mobile users and physical entities and electronic services. We think the physical world and the virtual world would both be richer if they were more closely linked.
     In this presentation, Mr. Mark Manners – Director Mobility Program Office and Cooltown Innovation, will discuss the work, the vision and the impact of Cooltown and webservices on the market.

IP3: Christie Digital Systems, USA Inc 
Talk by Mr. Jonathan Lim and exhibition

Immersive Market: VR and Simulation
The constant aim to recreate realities has first propelled the growth of the simulation market and in the recent years, formed the foundation for the genesis of virtual reality (VR). People are now able to regenerate realities that are more than real as well as to explore actualities that used to be inaccessible to us. This paradigm shift has proposed new potential of a new market, known as the immersive, as a major contributor to societal infrastructures such as science, manufacturing, medicine, marketing, telecommunications, entertainment, education, medicine, art and media. 
     In this presentation, Mr. Jonathan Lim seeks to explore on the market’s formation and the evolution that it has undergone as well as to discuss the driving forces behind its rapid growth and the ways the application has helped in transforming visions into realities.

IP4: NTUC Income 
Exhibition and hands-on demonstrations in the foyer

BigTrumpet project will be showcasing various scenarios and consumer service applications within the portal.
     BigTrumpet.com is a collaboration between Singapore Infocomm Development Authority (IDA) Microsoft and NTUC Income to build community web services for the public sector, private sector and all people. BigTrumpet.com aims to aggregate useful daily-life public sector and private sector services into simple and easy-to-understand scenarios, for the convenience of the people at anytime and any place.
     For organization, BigTrumpet.com will be a place where they can easily integrate and operate their business by simply "plugging-in’ to known standards and processes. It will be an attractive channel through which their services can reach out to the public through the latest web services technology.

IP5: Konica Minolta Photo Imaging Asia H.Q. Pte Ltd
Exhibition and hands-on demonstrations  in the foyer

Minolta Non Contact 3D Digitizer VIVID 910 is a compact and portable state of the art digitizer that is no bigger than a computer CPU. It comes with 3 interchangeable lenses: Tele, Middle and Wide lens that meets the challenge of scanning objects of different sizes.
Using a laser light stripe, the VIVID scans over 300,000 points in just 2.5 seconds. VIVID also captures color images that are equivalent to a 3 CCD digital camera with full 24-bit color depth.  With auto focus functions the VIVID does away with the need for lengthy set up and calibration time before and during the scanning process. Just frame the object in the LCD viewfinder and press a button. With an optional Compact Flash Memory Card the VIVID becomes the world’s only truly portable 3D digitizer. Scanning has never been easier.
