Display-control compatibility: the relationship between performance and judgments of performance.
This study examined whether people can judge the usability of display-control mappings. Participants identified one of two alternatives which were presented in a questionnaire. Several types of stimuli were tested, ranging from simple shapes to semantic stimuli. Choices were found to be predominately correct when usability was defined by an unambiguous spatial relationship between displays and controls. In contrast, estimates were less accurate for items which did not solely rely on spatial congruence. The findings were interpreted in terms of the factors that need to be considered for judgments to be free of error.
