The computer industry often measures mouse sensitivity in terms of counts per inch (CPI) or dots per inch (DPI). When comparing mice, you can compare CPI and DPI directly as it is the same measurement. Mouse speeds by technology below;
The first commercially available computer mouse was for Apple's Lisa computer and it was based largely on the Xerox PARC designed mouse. The Xerox PARC was the beginning of the mouse driven Graphic User Interface (GUI) that Apple and Microsoft modeled their operating systems after.
The first mice were using a mechanical ball. Mechanical ball mice had a small ball in the bottom that communicates the mechanically via small rollers which are turned as you move the mouse. Then optical mice were introduced which had no moving parts and offered more precision, Optical mice utilize a light-emitting diode and photodiodes to detect movement. The colour of the optical mouse's LED can vary, but red is the most common and least expensive to manufacture. Other colours can be used and I’ve used blue LED mice. In 1998, the laser mouse was invented and became mainstream by 2004. Laser mice utilize a laser for even more accuracy and makes for excellent gaming mice. Now Microsoft offers BlueTrack mice which combine optical and laser technology to work on almost any surface with great accuracy.
