A Non-traditional Approach Painting with Light [Bandyopadhyay, Raskar, Fuchs 2001]

Goals Understand advantages of Spatial AR Discuss issues in traditional AR approaches Explore alternative AR methods Graphics, Vision, Optics techniques Learn math of rendering and calibration See new applications in art and industry What we will not cover Fundamentals of AR and VR

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 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/people/raskar/raskar.html

Part 2: Introduction to Current Approaches for AR (Bimber) I want to give you an overview about what is to be due of this lecture. At first I‘m going to introduce you in our work. Then I tell you some details about our subproject frustum reconstruction Then I give the word to my associate Emanuel, who displays you our subproject Lowcost optical tracking with some live demos . Last but not least he presents the conclusions and further working possibilities of our project.
