• It allows a user to control the motion of a computer cursor.
• It also select objects on the screen by moving and clicking the device.

interface with personal computers after testing with various devices showed it to
be the most convenient and simple to use.
• The mouse works on the basic principle that the movement of the device is
translated into the movement of the cursor on the screen.

9. 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.
10. 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.

• It consists of a ball held by a socket containing 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.
13. MECHANICAL MOUSE OR BALL
MOUSE
• A mechanical mouse is a computer hardware input device comprised of a metal or
rubber ball in its underside.
• Moving the mouse causes the ball to roll, and sensors inside the mouse detect the
movement of the ball and consequently send signals to the cursor on the screen.
14. FUNCTION OF MOUSE
• Move the mouse cursor - The primary function is to move the
mouse cursor on the screen.
• Open or execute a program- Once you've moved the cursor
to an icon, folder, or other object clicking or double clicking that object opens the
document or executes the program.

using the drag and drop method.
• Scroll - When working with a long document or viewing a long webpage you
may need to scroll up or down which can be done using the mouse wheel or
clicking and dragging the scroll bar.
17. • Because a laptop is designed for portability almost all laptops today use
a touchpad as the mouse, and some lenovo laptops still use a trackpoint.
18. What does a smart phone or tablet
use for a mouse ?
19. • Smart phones and tablets use a touch screen as their primary input device, and
therefore your finger is the mouse on these devices. With most tablets, you also
have the option to connect a computer mouse and use it on the tablet.
20. HOW HAS THE DESIGN CHANGED?
• The computer mouse has definitely changed size, getting smaller and smaller.
• The design has also become more comfortable to hold, as the first computer mouse
was quite square.
• Motion detectors have changed from a tracking ball, 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.
• A ‘scroll wheel’ is also available on most mouses, making it easier to view web pages
and folders.
