DESIGN OF A PICTURE LANGUAGE TO IDENTIFY VEHICLE CONTROLS. III. A COMPARATIVE EVALUATION OF SELECTED PICTURE-SYMBOL DESIGNS

Abstract : This study investigated the accuracy of identification of each of 90 picture-symbol designs with each of 34 vehicle control names. Two sets of designs were evaluated. The set which had been empirically derived in a preceding study was found to be more effective than the set which had not been empirically derived. Effective symbols were found for 24 out of 34 vehicle control names. Ten new symbols have been developed. They will be presented subsequent to further evaluative tests. (Author)
