While zoomable user interfaces can improve the usability of applications by easing data access, a drawback is that some users tend to become lost after they have zoomed in. Previous studies indicate that this effect could be related to individual differences in spatial ability. To overcome such orientation problems, many desktop applications feature an(More)
Existing information-visualization techniques that target small screens are usually limited to exploring a few hundred items. In this article we present a scatterplot tool for Personal Digital Assistants that allows the handling of many thousands of items. The application's scalability is achieved by incorporating two alternative interaction techniques: a(More)
ZuiScat is a visualization concept for querying large information spaces on Personal Digital Assistants (PDA). Retrieval results are presented in a dynamic scatterplot, which is enhanced by geometric and semantic zoom techniques to provide smooth transitions from abstract visual encodings to data content. The same visualization is also used to manage(More)
Definition Zooming facilitates data presentation on limited screen real-estate by allowing the users to alter the scale of the viewport such that it shows a decreasing fraction of the information space with an increasing magnification. Hence the system may first present a global overview of the information space for the benefit of orientation, and in a(More)
Due to continuous and rapid advances in mobile hardware and wireless technology, devices such as smartphones and personal digital assistants (PDAs) are becoming a truly mobile alternative to bulky and heavy notebooks, allowing the users to access, search and explore remote data while on the road. Application fields that benefit from increased staff mobility(More)
Maps are currently the most common application domain for zoomable user interfaces (ZUIs). Standard techniques for controlling such interfaces on pen-operated devices usually rely on sequential interaction, i.e. the users can either zoom or pan. A more advanced technique is speed-dependent automatic zooming (SDAZ), which combines rate-based panning and(More)
Previous research has shown that alphasliders are an effective tool for searching an alphabetically sorted list when only limited screen space is available for the graphical user interface. To improve user satisfaction, we propose equipping the widget with a novel text filter to dynamically limit the slider range. In this way, users are supported in(More)
Zusammenfassung. Es werden zwei neuartige Systeme zur Darstellung und Exploration großer Datenräume auf kleinen Bildschirmen vorgestellt. Die Basis der Applikationen bildet ein Punktdiagramm, welches aufgrund seiner komprimierten Datenkodierung eine effektive Ausnutzung der Präsentationsfläche kleiner Bildschirme erlaubt. Ein weiterer Vorteil des Diagramms(More)
