Automatic trace analysis and comparison system for interactive learning and training systems

A learning and training process, comprising:

• storing traces of a learner solving an exercise as learner traces on a non-transitory computer readable memory;
• using one or more computer processors to attach meta labels to the learner traces;
• using the one or more computer processors to compare the learner traces to reference traces of a referent solving the exercise, meta labels being attached to the reference traces;
• using a displaying device for:
• displaying a visualization of at least one of the learner traces adjacent a visualization of at least one of the reference traces;
• displaying a visual indication of actions common between the at least one of the learner traces and the at least one of the reference traces;
• and
• displaying a visual indication of actions different between the at least one of the learner traces and the at least one of the reference traces;
• wherein the reference traces and the learner traces include indicators of:
• modification in a simulated printing process;
• observation in the simulated printing process;
• and
• measurement in the simulated printing process,
• and wherein the using the one or more computer processors to compare includes assessing virtual time and virtual costs for each action corresponding to the indicators of modification, observation and measurement.
