Abstract: The authors investigated the effectiveness of pictograms in manufacturing settings, where supervisors and workers often do not share the same language or cultural background. Pictograms for manufacturing steps, such as |cut|, |push| and |measure|, were designed. Their comprehensibility was examined by questionnaires and a comprehension experiment. The questionnaires were presented to 73 Japanese and 34 Portuguese-speaking subjects. The experiment was conducted with Japanese subjects and each subject|s response time to the pictograms was measured. The pictograms for procedures performed by a body part induced erroneous responses when they did not include the object of an intended action. On the other hand, the pictograms for procedures using a tool, such as cutting and measuring, tended to be comprehended more correctly and spontaneously. The results indicate that well-designed pictograms for an action combined with the illustration of an object can be used effectively in manufacturing settings, where safety and productivity are critical.
