10. OPTICAL MOUSE
• An optical mouse is an computer pointing device that uses a
light-emitting diode
an optical sensor, and digital signal processing ( DSP ).
• This mouse doesn’t have mouse ball and electromechanical
transducer.
• Movement is detected by sensing changes in reflected light,
instead of interpreting the motion of a rolling sphere.

11. WIRELESS MOUSE
• The Mouse without wire or cord is called wireless mouse
or cordless mouse.
• Most wireless mice use radiofrequency (RF) technology
to communicate
information to your computer.

sensors to detect a rotation of the ball. The user
rolls the ball with the thumb, fingers, or the palm of
the hand to move a pointer.

14. MECHANICAL MOUSE OR BALL

getting smaller and smaller.
• The design has also become more comfortable to
hold, as the first computer mouse
was quite square.

to an LED light, and now a laser. This improves the
quality of motion we see on the screen, and also
eliminated the use of the mouse pads.

making it easier to view web pages and folders.
