Flip zooming is a novel focus+context technique for visualizing large data sets. It offers an overview of the data, and gives users instant access to any part. Originally developed for visualizing large documents, the method might be adapted for different types of information, including web pages, image collections and as a general windowing interface. A first practical demonstration of flip zooming is the Zoom Browser, a World Wide Web-browser that uses flip zooming to present web-pages.
