Spatial interactive visualization on small screen

Abstract

The amount of data stored in personal digital devices increases rapidly as their memory capacities increase. These devices are usually equipped with relatively small displays, which makes presenting the information a challenge. We set out to explore the spatial design space for small screen user interfaces by incorporating additional dimensions into the visual representation, and investigate techniques that may be used to display more information at once. We focus on interactive visualization, with a document manager as a target application. We present the design factors and a simulated application running on a desktop computer. We also report a formative usability study with promising results.
