Estimating the term…
A training system for use in a wide variety of training tasks and environments comprising a user interface simulating the same information available to a trainee in the task environment which allows the trainee to assert actions to the system; a domain expert which can use the same information available to the trainee and carry out the same task; a training session manager for evaluating such trainee assertions and providing guidance to the trainee appropriate to his acquired skill level; a trainee model which contains a history and summary of the trainee actions; an intelligent training scenario generator for designing increasingly complex training exercises based on the current skill level and any weaknesses or deficiencies that the trainee has exhibited in previous interactions; and a blackboard that provides a common fact base for communication between the other components of the system. The domain expert contains a list of "mal-rules" which typifies errors usually made by novice trainees. Also, the training session manager comprises "intelligent" error detection and error handling components. The present invention utilizes a rule-based language having a control structure using a specific message passing protocol for tasks which are procedural or step-by-step in structure. The trainee may reach "the solution" by any of a number of alternate valid paths.
A computerized intelligent training system adaptable for use in the training of a trainee having a current skill level in the performance of at least one of a plurality of training tasks within a specific task environment, where the performance of each task comprises performance of certain procedural steps called actions such that each task has at least one desired action called a correct action and training is accomplished using the system by having the trainee perform simulated task by performing simulated actions on a computer, the computer system comprising:
A computerized intelligent training system adaptable for use in training persons, called trainees, in the performance of training tasks in a specific task environment, the computer system comprising a plurality of modules, each module comprising a set of production rules, said rules of the various modules acting in concert to implement the system, wherein said modules communicate with each other via an intermodule interface by means of messages sent in accordance with a message passing protocol, wherein all of said modules may write facts to said intermodule interface and all of said modules may read facts from said intermodule interface, and wherein each said message, to comply with said message passing protocol, contains facts indicating which of said modules sent the message and which of said modules is to receive the message.
The computer implemented method of training a trainee having a skill level to perform actions necessary to accomplish the training steps of a training task in a specific task environment, the trainee performing trainee actions at various times in the training, the various actions being represented by rules, the method using a computer having modules comprising sets of rules and including an intermodule interface to which facts may be written by modules and from which facts may be read by other modules, comprising the steps;
