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.

Famous quotes containing the word nod:
“Wynken, Blynken, and Nod one night
Sailed off in a wooden shoe—
Sailed on a river of crystal light,
Into a sea of dew.”
—Eugene Field (1850–1895)
“Sometimes we see a cloud that’s dragonish,
A vapor sometimes like a bear or lion,
A towered citadel, a pendant rock,
A forked mountain, or blue promontory
With trees upon ‘t that nod unto the world
And mock our eyes with air. Thou hast seen these signs;
They are black vesper’s pageants.”
—William Shakespeare (1564–1616)
“Romance, who loves to nod and sing,
With drowsy head and folded wing,”
—Edgar Allan Poe (1809–1849)
