Feedback (Loop, Automatic Control Operation)

About

With instant choice, you start choosing something, you don’t like it, you just switch. Users don’t really perceive the benefit of giving explicit feedback, so they invest less effort.

Loop

Open-loop control

IF (time_for_action = TRUE) THEN
    take_action(X)
END

Discrete closed-loop control

IF (time_for_action = TRUE) THEN
    measure(Y)
    IF (Y = specified_condition) THEN
        take_action(X)
    END
END

Continuous closed-loop control

WHILE (Y <> specified_condition)
    take_action(X)
    measure(Y)
    wait(Z)
REPEAT
