ACM UIST 2000 - Speed-Dependent automatic zooming for browing large documents

They propose a navigation technique for browsing large documents that integrates rate based scrolling with automatic zooming. The view automatically zooms out when the user scrolls rapidly so that the perceptual scrolling speed in screen space remains constant. As a result, the user can efficiently and smoothly navigate throgh a large document without vecoming disoriented by exremely fast visual flow. An informal usability study suggest that a document browsing task, most subjects prefer automatic zooming and the technique exhibits approximately equal performance time to scroll bars, suggestion that automatic zooming is a helpful alternative to traditional scrolling when the zoomed out view provides appropriate visual cues.
