Did you know even the old-school computer mouse uses light to work?
The new school just don't have a mechanical component of a ball and two rollers which spin two separate "gears" which blocks light and then math to figure out the horizontal change + vertical change.
I found that pretty neat when I learned. (I'm old enough to remember the pains of using a gunked up ball mouse.)
- kevin_thibedeau 8y agoThe old-school mice were also called "optical mice" because the old-old-school mice used mechanical sensors.
- watmough 8y agoFor old-school meaning about '85 or so, 'optical mouse' meant a mouse on a special gridded pad that worked optically.

That's not a regular mouse pad, it's a special red/blue/silver grid detected by a laser in the mouse.
