The optomechanical mouse uses a ball that rolls wheels inside the mouse, each containing holes detected by sensors. As the wheels spin, the lights represent mouse movement on the x and y axes. While more accurate than mechanical mice using only wheels, optomechanical mice are not as precise as optical mice. It functions similarly to mechanical mice but uses LEDs and photodetectors to sense ball movement and translate it to cursor position.

2.  The optical-mechanical or optomechanical
mouse consists of a ball that rolls one of two
wheels inside the mouse. Each wheel contains
a circle of holes or notches, allowing an LED
light to shine through and be detected by a
sensor. As the wheel spins these lights
represent an X or Y axis for the mouse
pointer on your screen. This mouse is more
accurate than a mechanical mouse that uses
only wheels and rollers, however, is not as
good as an optical mouse.

4.  •Basic construction of optomechanical
mouse is same as that of the mechanical
mouse.
 •Only different is in the sensing circuit i.e
a combination of LED and photo detector
is used to sense the distance travelled by
the mouse.
 •In this mouse, there are two rollers as
similar to the mechanical mouse. Each
roller is connected to a wheel . There are
small opening on the rim of each wheel.
 •As the wheel rotates a pair of LED and
photo detectors detect the number of
opening passed between them.

5.  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.
