Mechanical
The most basic form of mechanical motion detection is in the form of a switch or trigger. These motion detection devices are common in our everyday lives. The keys of a typewriter, or even the keys on the keyboards used to type this article employ a mechanical method of detecting motion. Each key is a manual switch that is either off or on. Each letter that appears is a result of motion on that corresponding key and the switch being turned on. This simple binary code concept is at the heart of the digital age, with mechanical switches being replaced by ever shrinking transistors.

Famous quotes containing the word mechanical:
“There is only one evil, to deny life
As Rome denied Etruria
And mechanical America Montezuma still.”
—D.H. (David Herbert)
“A committee is organic rather than mechanical in its nature: it is not a structure but a plant. It takes root and grows, it flowers, wilts, and dies, scattering the seed from which other committees will bloom in their turn.”
—C. Northcote Parkinson (1909–1993)
