The Campfire will have two main aims: sharing information and forging new directions. Because of the interesting mix of disciplines, there will be both introductory information-sharing sessions and more focussed panels and presentations which concentrate on the challenges of interdisciplinary collaboration. All attendees will compose a short position paper, indicating their area of expertise, what they would like to learn from this Campfire, and issues they wish to discuss. A program will be developed which incorporates all of the elements just mentioned, i.e. tutorial-style presentations, more detailed descriptions of research problems, personal experiences: problems and solutions, panel discussions following each set of presentations on specific themes and more wide-ranging explorations of future directions and collaborations. More informal sessions and discussions may be continued during breaks and in the evenings.

The invited submissions will guide the selection of the topics to be discussed. Places on the campfire are restricted, and will be allocated on a first-come, first-served basis. A place will be reserved for you upon receipt of your position paper. This will be confirmed once you have registered and paid the appropriate fee. Here we have provided a list of suggested questions, which we hope will inspire further ideas from all participants:

• Realistic Image Synthesis: What are the remaining "big issues"? How does this community feel that perception can be used to achieve true realism? What parts of the image can be rendered at a lower level of detail, or even eliminated, without the change being perceptible to the viewer?



• Metrics and Evaluation: How does the CG community feel about the issue of wanting to see some experimental validation of the effectiveness of new proposed techniques? What good metrics can be used to evaluate image realism? Animation is particularly difficult to evaluate, due to the high number of variables involved: how do we develop appropriate psychophysical investigations without examining each factor in isolation?



• Perceptually-based acceleration of interactive graphics: What are the main challenges in interactive rendering? Can we use psychological data to develop heuristics which may be used for perceptually adaptive simplification techniques? What types of simulation can afford to be degraded without people knowing? When do we need physically-accurate handling of events such as collisions, and when can we cheat? What can we learn from research about attention?



• Virtual Reality: How do we achieve a feeling of full immersion or "presence" in a virtual world. What do we know about haptic input? How do we effectively deal with the multiple modality of such environments?



• Eye-movements and Eye-tracking: It has long been established that many visual processing tasks deteriorate at increasing eccentricities from the fixation point. How can this be exploited in all areas of graphics generation? Can eye-movement patterns give us invaluable information about the way that humans view rendered scenes and animation? To what extent could we exploit the phenomenon of change-blindness, which may occur after an eye-movement, to mask the imperfections of our graphical simulations?



• Perception and Visualisation: How can we develop more effective techniques for portraying the 3D spatial relationships between objects? What are the visual cues in an image or animation which provide information about depth, contact and motion. What role does colour play?



• Interdisciplinary Collaboration: How do we successfully build collaborations between CG people and psychology researchers? How can the results of research in graphics, VR, perception, neuroscience, eye-movements, optometry etc.. be integrated in a timely fashion?
