Mechanical Mouse: A mechanical mouse has inside of it a ball which comes in contact with the desktop or mousing surface. As the user moves the mouse around on the desktop, the ball rolls with these movements. This rolling is detected by two wheels at 90 degree angles from each other which are positioned in this way so that one wheel can detect up & down movement, while the other detects left and right movement, together they can reliably detect mouse movement in any direction. A third wheel, the guide wheel is spring loaded and presses the ball against the two sensor wheels.Optical Mouse: Optical mouse use LED and photo technology to detect movement, rather than a physically moving ball. It tracks the cursors movement through photo sensors which take over 1,000 pictures per second. This instantly tells the computer the position of your mouses cursor.
