Zoomable User Interfaces for the Authoring and Delivery of Slide Presentations

Title of Dissertation: ZOOMABLE USER INTERFACES FOR THE AUTHORING AND DELIVERY OF SLIDE PRESENTATIONS Lance Everett Good, Doctor of Philosophy, 2003 Dissertation directed by: Professor Benjamin B. Bederson Department of Computer Science Millions of slide presentations are being authored and delivered with computer software every day. Yet much of the computer’s power for these tasks remains untapped. Existing interaction techniques leave presenters wrestling with limited size computer displays to get meaningful overviews of their work. Without these overviews, they have trouble finding patterns in their data and experimenting with alternate organizations. They also have difficulty communicating the structure of large or complex talks to the audience and keeping the audience oriented during unexpected transitions between ideas. A natural solution is Zoomable User Interfaces (ZUIs) since they offer the capability to view information at multiple levels of detail and smoothly transition between ideas. This work presents two ZUIs, Niagara and CounterPoint, for authoring and delivering slide
