Taking advantage of preattentive processing in information visualization can greatly improve intuitiveness of representations yielding in a faster and more natural way of acquiring information.
A partial list of preattentive visual features, together with references to research that showed they were preattentive.[Chipman, 1996],
Detecting the Red Object preattentively.[Healey et al., 1996] One visual variable and very easy to find it.
Detecting the Circle preattentively.[Chipman, 1996] It is more difficult but still preantentiv.
Examples of two target detection tasks: (a) target can be detected preattentively because it possess the feature “filled”; (b) target cannot be detected preattentively because it has no visual feature that is unique from its distractors.[Healey et al., 1996]
Region segregation by form and hue: (a) hue boundary is identified preattentively, even though form varies randomly in the two regions; (b) random hue variations interfere with the identification of a region boundary based on form.[Healey et al., 1996]
Any visual processing of that item prior to the act of selection can be called “preattentive”.[Wolfe, Treisma, 2003]
Preattentive processing can help to rapidly draw the focus of attention to a target with a unique visual feature (i.e., little or no searching is required in the preattentive case). [Healey, 2005]
