1. A computer-based engineering knowledge acquisition system, comprising: a digital processor supporting a user-interactive training material associated with a respective domain that includes at least one diagram; a display monitor coupled to the processor and rendering to an acquirer-user at least one screen view of the user-interactive training material, the at least one screen view having any of text and graphics in a certain locational arrangement relative to graphical content; and an eye-tracking member coupled to the processor, the eye-tracking member (i) tracking eye movement of the acquirer-user viewing the at least one screen view, and (ii) detecting eye traces of the acquirer-user for the at least one screen view; in response to the detected eye traces, the processor generating a summary of knowledge acquisition patterns of the acquirer-user and assessing whether the acquirer-user has missed viewing one or more regions of the at least one diagram; and a rules engine coupled to the processor, the rules engine performing an evaluation of the acquirer-user's viewing of the at least one screen view based upon the detected eye traces and the generated summary of knowledge acquisition patterns, and the rules engine providing one or more metrics as real-time feedback to a user.
