OFMspert II: intelligent tutoring for complex control

This paper begins with a discussion of the perceived requirement for general psychological models to underpin the design of human interaction with complex systems. A proposal is made that general psychological models may not be necessary, if indeed possible to create, for many applications of interest. For the applications of interest, cognitive engineering or human-machine systems models, such as the operator function model (OFM), may suffice. Next, a brief overview of the current state of OFM and its computational implementation, OFMspert, is presented. It describes how OFMspert has been extended to support the design of two intelligent tutoring systems (ITS) for operational control of safety-critical systems. An intelligent tutoring system requires two models: an expert model and a student model. This paper describes how the OFM can serve as the basis of the expert model and the OFMspert architecture as the basis for the architecture of the tutor itself.
