User interface designers still have to rely on personal creativity and skill when designing computer icons for program functions that have no existing conventional representation. Further, designers often stumble upon usable icons by trial and error. We designed an Icon Intuitiveness Test to gain better insight into how users interpret icons. Our hypothesis was that users would interpret icons ...
