The Mobile Tree Browser: A Space Filling Information Visualization for Browsing Labelled Hierarchies on Mobile Devices

This paper describes a new information visualization technique for browsing labelled hierarchies on mobile devices. The display is optimized for readability and navigation on devices with limited display space, using animation to smooth the transition between views when a user clicks on nodes to navigate the hierarchy and fisheye-distortion to brows long lists. The technique is evaluated by comparing it to more traditional text based table and node-link tree views with users expressing a clear preference for the space filling hierarchy view. This demonstrates the potential of information visualization to improve interface usability and functionality on mobile devices.
