The Future of Virtual Reality: Head-Mounted Displays Versus Spatially Immersive Displays

The head-mounted display (HMD) is the de facto display device for "true" virtual reality (VR) systems. However, walk-in spatially immersive displays (SIDs) such as CAVE and domed projection environments promise to challenge the HMD's role in VR display. This panel compares the ultimate utility of HMDs and SIDs in various VR applications. Issues include user mobility, single- and multi-user interactivity, stereoscopic viewing, applicability to augmented reality, visual quality, viewer fatigue, and sense of presence.

Roundtable: Art on the Web, the Web as Art

Web-specific artwork and art sites on the Web are fostering a seamless environment in which the boundary between the artwork itself and the "space" it inhabits is vanishing. The Web offers the promise of a direct and intimate connection between artist and audience, and requires a shift in aesthetics and approaches to storytelling, narrative, and interaction. This panel explores the interface of art and art space, and the dynamic qualities of art created for the Web.

VRML: Prelude and Future

As it enables interactive 3D graphics on the World Wide Web, the Virtual Reality Modeling Language (VRML) is triggering fundamental changes in accessibility, economics, mindset, and membership for the 3D graphics community. A panel of experts examines how this collaborative standards process works and where VRML is going next.

Breaking the Myth: One Picture is NOT (Always) Worth a Thousand Words

We need to understand both the power and frailty of images (compared to words, for example) to be able to effectively use new visualization and computer graphics technologies in science, education, entertainment, life, and most importantly on the World Wide Web. The panel and audience discuss and debate the weaknesses of images, including the difficulty of using them to represent information clearly; the dependency of visual and information perception on past memories, experiences, beliefs, and culture; the difficulty of making effective use of color; and what could be learned from the art and design communities.

Digital Stunt Doubles: Safety Through Numbers

Logical precursors to computer-generated actors are digital stunt doubles, computer-generated human figures designed to stand in for human actors for visual effects that are either too dangerous, too expensive, or impractical to shoot with human doubles. In this panel, visual effects supervisors present and discuss their application of digital stunt doubles to feature film projects.

Global Multi-User Virtual Environments

Networking technology and virtual environment technology are ready to enable shared, distributed, cooperative activities. This panel addresses infrastructure, systems, and applications related to multi-user virtual environments, especially the global (intercontinental/international) aspects of these issues.
