An Expert System for the Selection of Input Devices

This research effort consisted of the development and implementation of a user interface model in an expert system. The model, User-Input Device Model (UIDM), was composed of three parts: user, device, and task components. The expert system, Input Device Selection Assistant (IDSA), applied primary and secondary measures of ergonomic criteria on combinations of the UIDM components to develop a knowledge base for the selection of an input device. Personal Consultant Plus provided the inference engine to determine the most appropriate device. Results of experimentation and experience taken from human factors literature composed the expertise.
