Even if a more perceptually valid code could be constructed, the effort would be wasted. The designer of a new symbology for Air Force or Navy charts must live within the confines of existing symbols because of the huge amount of effort invested in the standards. We have many standardized visualization techniques that work well and are solidly embedded in work practices, and attempts to change them would be foolish. In many applications, good design is standardized design. Conventional symbol systems persist because they have become embedded in ways in which we think about problems.

The processing of certain kinds of sensory information is hardwired and fast. We can represent information in certain ways that are neurally processed in parallel. 8, which shows five different textured regions. The two regions on the left are very difficult to separate; the upright Ts and inverted Ts appear to be a single patch. The region of oblique Ts is easy to differentiate from the neighboring region of inverted Ts. The circles are the easiest to distinguish (Beck, 1966). The way in which the visual system divides the visual world into regions is called segmentation.
