We have developed several basic components for our Virtualized Classroom project: automated data collection, intelligent media integration, and flexible user interfaces. As an example of media integration, we show that when the PPT slides are projected onto the digital whiteboard where the instructor annotates, modifies, or expands the PPT presentation, geometrically registering high-resolution images from the two sources yields high quality digital presentations (e-presentations). We use a low-cost digital camera as a bridge to align the two sources and present a hybrid registration approach to align the PPT and handwriting images. Experimental results are presented to validate our approach.
