3) MECHANICAL MOUSE

The mechanical mouse is what we use in the good old days and one of the
most traditional mice in the history of computers. It is otherwise known as a
ball mouse because it uses a rubber ball to detect motion – That ball spins
along as you move the mouse, and sensors will pick up on which direction
you moved.

4) OPTICAL MOUSE

This is the common Joe mouse that you see everywhere these days. But instead of
using a rubber ball and mechanical sensors, an optical mouse uses an LED and
detects movement by sensing changes in the reflected light.

5) LASER MOUSE

The laser mouse is also a kind of optical mouse, and the working principals are the same
– To sense the movement by reflecting light. But just as the name implies, a laser mouse
uses a laser beam instead of an LED. This basically allows the mouse to be used on glass
and plastic surfaces due to the different properties of light but suffers from some
inaccuracy.

6) GAMING MOUSE

While a typical mouse usually only have 3 buttons, a gaming
mouse is characterized by having many buttons and touting
itself to be accurate. These extra buttons are often
programmable to do various things… Mostly for the purpose of
gaming.

7) TRACKBALL MOUSE
