Samenvatting
In this paper, the authors describe the concept of the proximity compatibility principle (PCP) and demonstrate its relevance to display design. Displays relevant to a common task or mental operation should be rendered close together in perceptual space. Different forms of task proximity are discussed, as are the different information-processing mechanisms that underlie the effects of the several different design manipulations of display proximity. Experimental data that support this process-based elaboration of PCP are then reviewed in design contexts relating to aviation, graphs, display layout, and decision aiding.
