Interacting with big interfaces on small screens: a comparison of fisheye, zoom, and panning techniques
Carl A. Gutwin, Chris Fedak · 2004
Mobile devices with small screens are becoming more common, and will soon be powerful enough to run desktop software. However, the large interfaces of desktop applications do not fit on the small screens. Although there are ways to redesign a UI to fit a smaller area, there are many cases where the only solution is to navigate the large UI with the small screen. The best way to do this, however, is not known. We compared three techniques for using large interfaces on small screens: a panning system similar to what is in current use, a two-level zoom system, and a fisheye view. We tested the techniques with three realistic tasks. We found that people were able to carry out a web navigation task significantly faster with the fisheye view, that the two-level zoom was significantly better for a monitoring task, and that people were slowest with the panning system. ways to solve this problem. First, applications can be redesigned for the smaller screen. Although there are examples of this approach (e.g., Pocket Word or Internet Explorer for PocketPC devices), it requires that multiple versions of the application be produced, and requires that users become familiar with a second GUI. There will also be cases where no redesigned version of an application is available—so another approach is needed. Key words: Large interfaces, small screens, mobile devices, screen space, zoom and pan, fisheye views. 1
