City Lights are space-efficient fisheye techniques that provide contextual views along the borders of windows and subwindows that describe unseen objects in all directions. We present a family of techniques that use a range of graphical dimensions to depict varied information about unseen objects. City Lights can be used alone or in conjunction with(More)
In this paper, we propose Zoomable User Interfaces as an alternative presentation medium to address several common presentation problems. Zoomable User Interfaces offer new techniques for managing multiple versions of a presentation, providing interactive presentation navigation, and distinguishing levels of detail. These zoomable presentations may also(More)
Software tools, including Web browsers, e-books, electronic document formats, search engines, and digital libraries are changing the way people read, making it easier for them to find and view documents. However, while these tools provide significant help with short-term reading projects involving small numbers of documents, they provide less help with(More)
The UC system employs hybrid quantum/continuous treemaps for fluidly interacting with documents in a personal digital library. By incorporating a document reader application within the visualization workspace, UC supports multi-document reading tasks that have been traditionally accomplished by laying out documents on a physical desk. One of the overall(More)
Making sense of information on computers is notoriously difficult because of limited size displays. Two interface techniques used to cope with these limitations are zooming and overview+detail. To evaluate these techniques, we ran a user study comparing a Zoomable User Interface (ZUI) and a folder-based overview+detail interface. The task used in the study(More)
This paper introduces a technique for viewing text objects under changing size constraints in 2D environments. Our approach automatically combines font size reduction and content reduction to preserve legibility of key words. Unlike traditional semantic zooming, our approach creates intermediate representations and transitions automatically. The main(More)
An advanced interface is presented for fluid interaction in a personal digital library system. The system employs a zoomable planar representation of a collection using hybrid continuous/quantum treemap visualizations to facilitate navigation while minimizing cognitive load. The system is particularly well suited to user tasks which, in the physical world,(More)
