Shape coding is a method of design of a control that allows the control's function to be signified by the shape of the control. It was used successfully by Alphonse Chapanis on airplane controls to improve aviation safety.
Famous quotes containing the word shape:
““Must a name mean something?” Alice asked doubtfully.
“Of course it must,” Humpty Dumpty said with a short laugh: “my name means the shape I am—and a good handsome shape it is, too. With a name like yours, you might be any shape, almost.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
