Why does the computer mouse sometimes jump in a random direction?
It shouldn't, when just sitting still. I assume you mean when you are moving it. Older mouses had a ball that made two different little wheels inside rotate, and that would be translated by the computer into mouse motion.
The Short Answer
It shouldn't, when just sitting still. I assume you mean when you are moving it. Older mouses had a ball that made two different little wheels inside rotate, and that would be translated by the computer into mouse motion. But those little wheels would pick up dust and gunk and that could make them get erratic. Most modern mouses use a laser diode emitter and a sensor. The laser diode shines a bright light at the surface, and tiny changes in the reflections back into the sensor are used to determine the direction that the mouse is moving. But if that sensor gets dirty, or the surface it is being used on is dirty or very uneven, then the software gets a bit confused. This can also happen on some very shiny or smooth surfaces, since there isn't much information for the sensor to work with.
