Feedback (Loop)

> User Interface (GUI)

1 - 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.

2 - Loop

2.1 - Open-loop control

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

2.2 - Discrete closed-loop control

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

2.3 - Continuous closed-loop control

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