Presenting Large and Complex Information Sets on Mobile Handhelds

Abstract

The opportunity to access information at any time and any place caused a boom in the development of small mobile devices in recent years. Due to their application, these handhelds become smaller and handier, which leads to new challenges in human-computer interaction. Due to limited resources of these devices new paradigms for information presentation and interaction facilities are needed. We take this into account by applying concepts for interaction and display of information from the field of information visualization to mobile pocket-sized devices. We focus on concrete problems caused by presenting huge images and large hierarchies in such environments. Moreover, we introduce an effective technique for browsing the World Wide Web via mobile handhelds. The presented techniques offer an improved support in navigation, orientation and interaction that enables the user to browse, interpret and handle presented information much more easily.
