NOD
NOD is a head-motion operated mouse device that Wilbur and Rod came up with one afternoon in about 1983. It works by putting a special reflective pencil behind your ear and a quadrature detector that track its movement. The point was to be able to use the keyboard while you used the mouse cursor. It had a RS-232C interface and cost $400 USD. Apple Inc. were presented with a prototype but the project it was intended for got canceled.

Sailed off in a wooden shoe—
Sailed on a river of crystal light,
Into a sea of dew.”

Must be won without pride,
With a nod from nature,
With a lack of strain,
And a loss of stature.”
