Abstract

This paper describes a web-browser based on the focus+context technique Flip Zooming. A prototype was developed and evaluated against an ordinary web-browser that used scrollbars on a small screen with a resolution of 160*160 pixels. A preliminary evaluation show that the prototype provides better overview and makes searching for specific items easier compared to the traditional browser. These findings indicate that there are constraints that have to be acknowledged when designing the user interface on small screens. Keywords Information Visualization, Focus+Context techniques, Small Screens, Flip Zooming INTRODUCTION The dramatically increased growth of mobile information technology, such as personal digital assistants (PDA:s) and cellular phones, raises new questions about interface usability. On web-browsers developed for ordinary screens, scrollbars are used in order to enable users to explore a page too large to fit into the screen. Is this strategy useful when designing for s...
