How Not to Have to Navigate Through Too Many Displays
Abstract and Figures
The three trends in information visualization attempting to address the problems caused by large networks of displays of raw data are information animation, integrated representations, and coordination of multiple views. Coordination of multiple views is used to create a virtual perceptual field or a workspace in which practitioners carry out their work activity and is the theme of this chapter. This chapter concerns how the characteristics of computer-based networks of displays shape the cognition and performance of practitioners. The chapter reviews common findings from field studies that have shown how large networks of displays, available through a limited keyhole, can place new mental burdens on users. It also provide an overview of some of the techniques that designers can use to break down the keyhole and help users focus on the relevant portion of the data field as activities unfold. The work in human-computer interaction concerned with this level of analysis of a computer based information system often goes under labels such as navigation, browsing, hypertext, dialogue design, or window management. This chapter discusses ways in which designers can coordinate different kinds of display frames within a virtual workspace. The chapter refers to this level of analysis and design as workspace coordination—the integration of the set of displays and classes of views that can be seen together in parallel or in series as a function of context.
