5. Speaker Oliver Bimber is currently 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 CG&A, 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 Siggraph’02 and was a speaker in the Siggraph’02 course “Building Interactive Workspaces”. Together with Ramesh Raskar, Bimber organized this course at Eurographics 2003 and 2004

6. 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. He was a course organizer and speaker for Siggraph 2002-2006. He is a member of the ACM and IEEE. http://www.merl.com/people/raskar/raskar.html

7. Speaker Masahiko Inami is a professor in the Department of Mechanical Engineering and Intelligent Systems at the University of Electro-Communications (UEC Tokyo), Japan. He directs the Human Interface and Interactive System research group. His research interests include multi-modal augmented reality, augmented human perception, display-based computing and telexistence. Optical Camouflage, one of his doctoral research at University of Tokyo, was chosen as one of the coolest inventions of the year by TIME Magazine in 2003. His technical papers have appeared in IEEE CG&A, resence, IEEE VR and other conferences. He has exhibited 15 installations at the Emerging Technologies of SIGGRAPH 1997 through 2005. He is a member of the ACM and IEEE Computer Society. http://inami.info/
