Keyboard as a Graphic User Interface

Usually abbreviated as GUI, it’s the term for physical shape, size, color and arrangement of the physical controls that put a human being in control of an industrial product. Designers of “personal technology” devices, perhaps game designers in particular, think about it a lot because it can spell the difference between a device that becomes easy and familiar — in short, a device one can play with — and one that’s a constant frustration.

The piano keyboard is an early and astonishingly successful example of an interface that expresses, or better, materialises an idea about sound. It also incorporates a sensitive and intelligent definition of “average” adult human hands — and ears and brains.
