how mouse pointer follow the motion of mouse?

[uday mehta]

i have a little knowledge about mouse technology. in mouse there is a sensor which sense the motion. and cursor follows that motion. there is an encoder which tells the position of mouse to computer. how this encoder works. And if i use another sensor for motion detection then how can i interface that with computer?

actually i want to make my own mouse using different sensor. question is that how will i tell to operating system that now i press left click and now i move my mouse to right etc.
Means i want the deep functioning of mouse. in which language and by which software i can do so? I saw a you tube video in which Mr. Belal control his system by keypad.

A mouse sends a code back to the host either as a TTL level serial stream (old type) or as a USB serial stream on newer types. The mouse doesn't know where it is, only which direction it is moving and whether a button has been pressed. All it does is send back a byte of data per movement of it's motion sensor. As far as I know, the only command you can send to a mouse is to request it's identity and it responds with either a single letter or in the case of a USB mouse, it's manufacturer and ID strings.
