NASA Kids Science News segment explaining the technology of the computer mouse.
Hi, I'm Jared with more computer news you can use.
00:00:00
My computer mouse broke.
00:00:07
How can I fix it?
00:00:10
First you have to know how a mouse works. It's an optomechanical device.
00:00:12
A what?
00:00:16
Let's break it down. Here, opto refers to light and mechanical refers to motion, like with wheels and shafts.
00:00:18
When you move your mouse, the ball on the bottom rotates two shafts attached to wheels that have small holes in them.
00:00:24
Cool! What's next?
00:00:32
Light emitting diodes send light beams through the holes and detect them on the other side.
00:00:34
As the holes spin by, the light is cut off.
00:00:39
The detector signal is sent to the computer to locate the mouse's cursor on your screen.
00:00:42
Now that we know how a mouse works, let's figure out what's wrong with your mouse and fix it.
