Opto-mechanical mouse has a ball with two freely rotational rollers, which are 90 degrees apart. One roller detects the forward-backward motion and other the left-right motion of the mouse.
In 3D Pinball place your cursor over the mouse, but do not launch the ball. On your keyboard type hidden test and then click the ball and hold the left click down, you can then move the ball with your mouse.

That's called a trackball. The device stays in place and you move the ball (usually) with your thumb, rather than moving a mouse which in turn moves the ball inside (or with the newer optical mouse, electronically senses the mouse motion).
Well the mouse sends the movements of it to the computer. A mouse with a mouse-ball has rollers inside of it that move with the ball and from there can operate similar to a keyboard. An optical or 'laser' mouse is much more advanced.
They both do the same job. And on an older mouse it's easy to see the similarities. An older computer mouse would have a ball underneath. Then as you moved the mouse around the ball would roll and the computer would count the rotations. A track ball was basically a mouse turned upside down. Instead of moving the mouse to rotate the ball, you'd move the ball directly with your fingers instead.
Bill English actually did not design the mouse. Douglas Englebart did. Bill English was one of the engineers who helped Englebart build it. He is credited with the introduction of the first commercial ball mouse.
The laser of the optical mouse may bounce off certain colors and shapes on a mouse pad.There are no disadvantages to a optical mouse. The optical mouse just works better and smoother than the ball mouse, and you never have to worry about the ball getting dirty or hanging. I would suggest getting an optical mouse and throwing the ball mouse away.
If the ball is on the bottom, it's a "roller ball." If it's on the top and meant to be touched, it's a "trackball."
A "ball mouse" or mechanical mouse is a computer mouse which detects user inputs using a system of servos detecting the movements of a ball (inside the mouse) which rolls on the desk surface. The most common alternative, the "optical mouse" uses optical sensors to detect user inputs. The optical mouse is widely considered to be superior in all important respects, and is therefore becoming much more common then their mechanical cousins.
