Graphics, User Interfaces This is the sixth article in a series on common usability and graphical user interface related terms [part I | part II | part III | part IV | part V]. On the internet, and especially in forum discussions like we all have here on OSNews, it is almost certain that in any given discussion, someone will most likely bring up usability and GUI related terms - things like spatial memory, widgets, consistency, Fitts' Law, and more. The aim of this series is to explain these terms, learn something about their origins, and finally rate their importance in the field of usability and (graphical) user interface design. In part VI, we focus on the dock.

Since the dock expands and contracts both east and westwards, you are never quite sure where each individual icon is currently residing (spatial memory, anyone?).


Thom, not knowing where the application is going to be and destroying spatial memory is a carefully constructed design feature. ;)

If the user can't rely on muscle memory, the user has to stop and think about what needs to happen. It's like a speed bump, it slows the user down making them think about what they are doing. Since the user is going slower thinking about what they are doing, they make fewer mistakes.
