Intelligent user interface for expert systems applied to power plant maintenance and troubleshooting

A research and development project is under way to specify, design, construct, and evaluate a user interface system to meet the requirements of a knowledge-based system for gas turbine electronics equipment maintenance and troubleshooting. The user interface is a portable device with text display, video and overlay graphics display, voice recognition and speech production, special-function keypad, and printer. A modular software structure based on a serial communications protocol between the user interface device and expert system host computer provides flexibility, expandability, and a simple, effective user-interface dialog.<
