Abstract: A computer based training system (1) resides on a server and allows a conventional client computer such as a PC to be used by a student to conduct a course. Information resource (30), content (37), and navigation (31) frames are generated by associated frame programs which operate independently. An Applet control program (32) is a frame program establishing a hidden frame. It receives requests from the information, content, and navigation frame programs and parses an XML content data file to take the necessary actions for progress through the course. The navigation frame program updates progress variables.

Abstract: A training system (1) has various media for interfacing with a user. A system controller (2) uses an interface file (17) to automatically execute action commands to perform an interfacing event. The action commands are delimited by interactivity point commands, execution of which halts an execution path and allows interactive inputs. A simulation program (19) may then be retrieved to allow the controller (2) simulate interfacing of the training subject. Screen controls are dynamically linked with simulation handlers of the simulation program. They are all disconnected after use of a simulation program. A combination of automatic interfacing and interactivity is achieved in a simple way for effective user training.
