Washing machine:
What is wrong?

Bad communication between user and system.

 Bad communication between user and system.

Gulf of Execution: 

How do I know what I can do?

What actions are allowed by the system?

How do I do it?

Gulf of Evaluation:

How do I know what happened?

What does it mean?

Have I accomplished my goal?

 The position of the controls on the keyboard is not logical; the hand have to move from one extreme to another of the surface. Changing the cycle the washing machine automatically resets the spin.

 Examples of control panel that work better

Suggestions:

• redesign interface so you have a linear flow of choice
• mechanical or LED buttons: evident state for other parameters
• rotary knobs with a timer or LED display: show time progression of the washing cycle
