Speaker
Oliver Bimber is a Junior Professor for Augmented
Reality at the Bauhaus University Weimar,
Germany. He serves on the editorial board of
the IEEE Computer magazine (graphics and
multimedia editor). Bimber invented several AR
displays, such as the Virtual Showcase,
Interactive Holograms and Augmented Paintings. He
published in several journals, such as IEEE
Computer, IEEE CGA, Presence, Computers and
Graphics, and at many graphics, AR and VR
conferences. Bimber is member of IEEE,
Eurographics, ACM and ACM Siggraph. He has
exhibited in the Emerging Technology Laboratory
of Siggraph02 and was a speaker in the
Siggraph02 course Building Interactive
Workspaces. Together with Ramesh Raskar, Bimber
organized the proposed course at Eurographics
2003 and 2004

Speaker
Ramesh Raskar is a Senior Research Scientist at
MERL-Cambridge Research. His research interests
include projector-based graphics, projective
geometry and non-photorealistic rendering. During
his doctoral research at U. of North Carolina at
Chapel Hill, he developed a framework for
projector based 3D graphics, which can simplify
the constraints on conventional immersive
displays, and enable new projector-assisted
applications. He has published several articles
on immersive projector-based displays, spatially
augmented reality and has introduced Shader
Lamps, a new approach for projector-based
augmentation. His technical papers have appeared
in SIGGRAPH, EuroGraphics, IEEE VR, IEEE
Visualization, CVPR and many other graphics and
vision conferences. He was a course organizer and
speaker for Siggraph 2002, 2003 and 2004. He is a
member of the ACM and IEEE. http//www.merl.com/pe
