checking to see if my mouse works on all things, and so far, all the places mentioned, it works. my head, hand, clothes, wood, paper, gloss paper, plastic, metal, ect..
however i did not try a mirror. im guessing that the signal would get reflected somewhere else, and not work. sometimes though, if i pick my mouse up to readjust my posistion on the pad, my pointer losses its posistion and jumps to some random place on the screen. its more of a annoyance than anything. anyone else experiance this kind of behavoir?

D_999 - Quick question, by word a motion sensor dectects motion, but in the early mouses, did it not do it with just mechanical parts?

they detect motion wiht light censors, not touch censors. Light censores have a light on them.

Even the early, early ones? - Like the kind when they were first invented?

I think you forgot some crucial information. An OPTICAL mouse does not use TOUCH censors.

No, no - I am NOT talking about a optical mouse, I am talking about the first "mice" invented!

This was Death_999's point though, those rollers are attached to larger wheels with spokes, and those spokes are in-between a sensor and something that looks like a transistor. I assume the transistor heats up, gives off IR, and the sensor detects the alternations that are casused by the spokes moving.

We did. You did. Yes we can. No.

Interesting. I remember hearing that the first widely distributed commercial mouse, the one made for the 1984 Macintosh, used an internal optical sensor. This allowed it to have very little resistance against motion (a problem with early mechanical mice); it also let them keep working for a long time since it had no bending parts aside from the button's spring.
