Design of a human-error-tolerant interface using fuzzy logic
This paper describes the development of a humanmachine interface which is tolerant of human error during the control of a simple industrial process. Human-error-tolerant interfaces (HETI) should be applied to industrial processes in order to keep the human operators sufficiently vigilant to enable them to handle unexpected events. With this goal, a global architecture for a HETI is proposed here; it integrates a human operator model (concerned with possible human actions and potential errors). For the design of this model, preliminary human behaviours and errors during the control of a simulated process have been analysed. This enables the authors to devise general rules, to be used when programming such an interface, using fuzzy logic. The HETI design and evaluation are described in the paper.
