Abstract
With the progress of the computerization in the society, it is needed to teach and transmit the methods of operating information-processing equipment and software to the beginners. This paper focused on the windows software operated using mouse and keyboard, and then modeled how manuals affect the type/occurrence rate of use error. A systematic experiment for forty panels was planned and implemented, with the observed data being analyzed statistically. According to the results, the occurrence rate of use error changes by the method of describing the manuals, and the relationships between them depend on the type/conditions of the operations. Moreover, based on these results, a method for evaluating a manual in respect of the error-proneness in the operations was proposed, and its effectiveness was examined through the application to a case.
