Controls for remote-controlled zoom lenses.
Experiments were conducted to investigate the expectation of members of the public of the relationship between a pair of pushbuttons, a rocker switch and the direction-of-zoom of a remote-controlled zoom lens. In neither case was a population stereotype found. Relatively large numbers of subjects suggested Zoom In/Zoom Out or Close-up/ Distant as labels for the zoom control buttons. A significant stereotype was demonstrated in a second experiment with a novel concentric button arrangement designed to embody the concepts apparent in the suggested labels.
