IE558 · TOPIC 03 CONTROL EXPERIMENT
A steady hand.
A changing system.
Explore how people adapt when the way they control a system changes. Your task is simple: keep two bars aligned.
01Practice the movementGet a feel for velocity control.
02Keep the centers alignedCorrect the blue bar when it shifts.
03Compare two sensitivitiesThe same task, a different response.
THE TASK POSITION ALIGNMENT

Model correction uses delayed model task error, never fit residuals. K describes the combined human and controlled system; it does not measure finger sensitivity. Validation across different sensitivities tests transfer, not within-condition repeatability.
