A Development of Virtual Reality Training System -An Application to Ordinary Mission of Electric Industry-

概要 （図表や脚注は「報告書全文」に掲載しております）

ＶＲ技術を用いて電気事業の通常業務を対象とする教育訓練システム（ＶＲＥＥＤＳ）を開発した。本システムは、既開発のトンネル火災時ＶＲ緊急時対応訓練システム（ＶＲＴＳ）のコンセプト（メニュー形式の訓練条件設定、ＶＲ訓練中の行動パスとアクションの記録、終了後の行動パスとアクション履歴の再生）をベースとしいる。ＶＲＥＥＤＳは、港湾における輸送容器のハンドリングと検査業務を例題として開発されており、あらたに、ネットワーク接続した２台のＰＣ（役割を分担）による協調訓練機能、ヒューマンエラーを誘う表示トラップの設置とうっかりミスによる作業忘れなどのエラーの警告・記録機能、訓練開始前の条件呈示と操作連数を行うブリーフィング機能、訓練結果を採点評価するデブリーフィング機能等を実装した。開発終了後に、輸送業務を行う関係者による試用とアンケートを行い、画像の質感や上記機能に関して高い評価を得た。

概要 （英文）

Our laboratory has been developed the virtual reality training system (VRTS) for emergency response in case of tunnel fire. As the result of development of the system, it was confirmed that VRTS is available for practical use for emergency response of electric industry, other industries and organizations. However, the problems, concerning to graphics reality, conversion to PC version, development of interface and indication of other workers, were extracted by persons concerned to electric industries. It is also supposed that a virtual reality training system of ordinary mission is also useful for efficient newcomers’ training and experts’ training concerning to human error.After needs sounding in various fields of electric industries, a new virtual reality training system of ordinary mission in radioactive materials transport was developed. This system has the following operational and technical characteristics. a) Two personal computers connected by Ethernet cable realize the cooperative training in the same virtual reality space. As the result of cooperative virtual reality training, each computer displays different viewpoint.b) Two trainees individually operate each personal computer that plays a director or a worker. Each computer program has different scenarios that are decided for the director and the worker. c) Human error inducing traps are set in the program, while omission errors are warned in the program. Those are also recorded in a file for debriefing.d) Before execution of training, an elementary training program of mouse operation and radiation measuring are prepared in briefing program. e) The virtual reality training consist of preparation of crane handling device, operation in a hold, radiation measuring, crane handling, operation on the transport vehicle and radiation measuring. Those virtual reality scenes except crane handling are executed sequentially or individually.After development of the training system, engineers concerned to radioactive materials transport executed a practical review. According to their review, the new virtual reality training system is practical in the ordinary mission of radioactive materials transport.
