Description¶

To separate trainee performance from disturbance effects in adaptive logic, the article describes passing the disturbance through a high pass filter and the error through a low pass filter, each with a 5 sec. time constant. This shaped-spectrum, filtered-error scheme has the advantage of fairly rapid response with less influence by the disturbance than instantaneous error, enabling difficulty level to be obtained as a function of filtered error.

Design Implications¶

Context¶

Requirements¶

• Filters must cut off sharply enough that difficulty level is not affected directly by the disturbance

Constraints¶

• The additional lag made the task easier but negated to some extent the attempt to reduce the direct influence of the forcing function on the difficulty level

Target Learners¶

• trainees in adaptive manual-control training systems

Target Learning Goals¶

• manual control skill
