| The goal of WITS Welding Intelligent Tutoring System is to provide a realistic and safe virtual reality environment to train electrical workers in performing standard alumino-thermal ground welding procedures on equipment in an electrical switching station yard. The WITS training system allows users to practice a variety of welding scenarios which satisfy company practices and provides help, feedback, and a performance evaluation. The Virtual Reality Interface, Expert System, Virtual Environment, and Monitoring modules of WITS are presented. This thesis focuses on the monitoring of human interactions in the WITS Welding Intelligent Tutoring System. The Monitoring module design includes welding task, manipulation, physics, scheduling, and weather agents. Implementation test results show the feasibility of this approach for monitoring the user's manual interactions in this training environment. |
