This chapter presents an overview of several recent developments in vision science and outlines some of their implications for the management of visual attention in graphic displays. These include ways of sending attention to the right item at the right time, techniques to improve attentional efficiency, and possibilities for offloading some of the processing typically done by attention onto nonattentional mechanisms. In addition it is argued that such techniques not only allow more effective use to be made of visual attention but also open up new possibilities for human–machine interaction.
Introduction
Graphic displays such as maps, diagram and visual interfaces have long been used to present information in a form intended to be easy to comprehend (e.g., Massironi 2002; Tufte 2001; Ware 2008). While it is clear that such a goal is important, it is not so clear that it has always been achieved. Are current displays for the most part effective – do they enable user performance to be rapid, easy and accurate? Are they optimally so? Or are better designs possible?
These concerns are discussed here in the context of how to manage visual attention in graphic displays (including visual displays). This chapter is not directly concerned with the design of displays that respond effectively to the user (e.g., Roda and Thomas 2006; Vertegaal 2003). Rather, it focuses on the complementary perspective: how to design a display so that the user responds effectively to it. Results here apply equally well to static, dynamic and interactive displays.
