The document discusses the history and types of computer mice. It explains that the mouse was invented in 1968 by Douglas Engelbart to control the movement of the cursor on a screen. Mice come in various forms such as optical mice which use light sensors rather than a ball, wireless mice which communicate via radio signals, and trackball mice where the ball is stationary and rolled by the thumb. The mouse's design has evolved over time from square wooden models to smaller, more ergonomic designs with additional features like scroll wheels.

3. WHAT IS MOUSE ?
• A mouse is an external computer hardware device.
• 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.
• During the 1980’s, computer mice became the dominant way for people to
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.

4. INVENTION OF MOUSE
The first computer mouse was publicly unveiled in 1968 by its inventor, Douglas
C.Engelbart.It was made of wood.

5. Mouse Physical Description
• Computer mice come in many shapes and sizes but are all designed to fit either
the left or right hand.
• The standard mouse has two buttons toward the front (to left-click and right-click)
and a scroll wheel in the center (to quickly move the screen up and down).

6. HOW THE MOUSE COMES ITS
NAME ?
It just looked like a mouse with a tail, and we all called it that.”

7. Mouse vs mice or mouses
When talking about one (singular) we refer to a computer mouse as a "mouse." When
talking about two or more (plural), we refer to them as "mice" or "mouses" although
"mice" is more standard.

8. TYPES OF MOUSE

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.

11. GSTICK MOUSE
• Gordon Stewart designed the Stick to add a more authentic and natural feel to
artistic manipulations on both Macs and PCs.
• These mice are Wireless and pocket-sized. It looks like a pencil.
• GStick mouse is like a pencil.
• It can be used for web browsing, office work or whatever you do with your
traditional mouse, with more comfort.

12. TRACKBALL MOUSE
• A trackball mouse is a pointing device.
• 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.

15. • Drag and drop -Once something is selected it can also be moved
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.

16. What does a laptop use for a
mouse?

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.

BUT NOW A DAYS THERE IS ALSO ANOTHER MOUSE
WHICH IS THE PART OF COMPUTER
