Abstract
Interactive multimedia agricultural work safety education software regarding springtime tilling by tractor was developed for use on a PC with mouse operation.
The scenes in the main part of this software are classified into 5 groups, and are composed of 19 individual scenes with associated questions. In individual scenes with questions, 98 questions are presented with scores of 1 to 5 per question, on a total of 78 question-and-answer screens. The results are ranked in 5 levels based on the score and displayed as a comprehensive evaluation, and the user can verify his/her awareness level regarding work safety.
To maintain the user’s motivation level, a variety of question and answer screens, such as multiple choice, image area selection, and specification of the correct sequence, were used. In addition, a total of 64 computer graphics (CG) movie clips with audio are played representing the contents of the answer, to increase the virtual reality experience and the feeling of being in a live situation. CG movie clips for wrong answers representing accidents intentionally used exaggerated expressions.
The software is intended for use as a safety training material, and 80% of the user base consists of organizations, such as regional agricultural extension centers. However, the effect of safety education was not consistent across generations, and thus further improvements are necessary.
