Don Norman's 6 Principles

Visibility - you can see (recognition) Feedback - activation feedback - click on mouse you can see mouse icon change few millisecond. behavioral - feedback click on icon and window pop up Affordance - when someone see something, they know how to use it. Mapping - mapping logic (control: effect) Constraint - user only have got limited option to do (toggle button --> can only turn on and off, not increasing or decreasing) Consistency - QWERTY keyboard -> all keyboard in the world based on the same QWERTY pattern.

Interaction Styles: Command language (CL) - like command line to execute something in computers Menu selection - only limit of lists are provided for users. Direct Manipulation(DM) - like drag and drop icon to bin means delete.
