The need for visualisation applications developed for small handheld devices such as PDAs and intelligent mobiles are growing. A visual user interface VUI model based on zooming user interface techniques (ZUI) to adapt two complete different visualization application areas on-line brand shopping and flood warning system for PDAs is presented. The on-line brand shopping was evaluated in a benchmark usability study comparing it to traditional PC based eNet shopping. This paper is also a blueprint to inform researchers and software engineers about our experience in developing visualization applications for PDAs with existing development platforms.
