Annotating 3D electronic books
Lichan Hong, Ed H., Stuart K. Card · 2005
The importance of annotations, as a by-product of the reading activity, cannot be overstated. Annotations help users in the process of analyzing, re-reading, and recalling detailed facts such as prior analyses and relations to other works. As elec-tronic reading become pervasive, digital annotations will become part of the essential records of the reading activity. But creating and rendering annotations on a 3D book and other objects in a 3D workspace is non-trivial. In this paper, we present our exploration of how to use 3D graphics techniques to create realistic annotations with acceptable frame rates. We discuss the pros and cons of several techniques and detail our hybrid solution.
