• Pictorial shape
• vision as user interface
• perspective cues
• pictorial depth

Human observers adjust the frontal view of a wireframe box on a computer screen so as to look equally deep and wide, so that in the intended setting the box looks like a cube. Perspective cues are limited to the size distance effect, since all angles are fixed. Both the size on the screen, and the viewing distance from the observer to the screen were varied. All observers prefer a template view of a cube over a veridical rendering, independent of picture size and viewing distance. If the rendering shows greater or lesser foreshortening than the template, the box appears like a long corridor or a shallow slab, that is, like a %26apos;deformed%26apos; cube. Thus observers ignore %26apos;veridicality%26apos;. This does not tit an %26apos;inverse optics%26apos; model. We discuss a model of %26apos;vision as optical user interface%26apos;.
