ABSTRACT
The authors developed an experience-based learning software named SIM-ERROR, on which we can learn human error prevention by using the point and call method. Many workers in Japan use the point and call method primarily to recognize objects and verify their correct operation. The SIM-ERROR includes five tasks, in which workers can experience various error prevention functions of the point and call method, by comparing their performances with vs. without the point and call method. The authors validated the effectiveness of each task in the SIM-ERROR software using training for train operators. A total of 736 apprentice train operators participated in the training. They performed one of five tasks and were shown their error rate graph. Next, the instructor explained to them the methodology of the task. Then the participants answered a five point scale questionnaire about the five human error prevention effect of the point and call method. A comparison of the respective mean subjective ratings for five point and call method functions, before and after the training session, indicated that the participants were more convinced of the human error prevention effectiveness of the point and call method after the training than before in the three of five tasks. In the other two tasks, there were no differences between pre- and post ratings, but very high ratings were shown.
