about the history of mouse ...uploded by usman

1. New Product Development

2. The Mouse !
 In computing, a mouse is a pointing
device that functions by detecting two-
dimensional motion relative its
supporting surface (a mouse pad)
 The name mouse, originated at the
Stanford Research Institute, it use to
have a cord at the back of the device
which resembled a mouse tail.

3. The invention of mouse
Douglas Engelbart changed the
way computers worked in 1964.
He invented the computer
mouse, a user friendly tool that
anybody can use.

4. HOW IT CAME TO BE!
 The trackball, the first version of the mouse was
invented by Tom Cranston, Fred Longstaff and
Kenyon Taylor who were working on the Royal
Canadian Navy‟s DATAR project in 1952. It used a
standard Canadian five-pin bowling ball. It was a
secret military project.

5. WHY DO WE NEED IT?
 The mouse allows the user to operate on a GUI
(graphics user interface) which is usually
displayed via a monitor.
 It is possible to use a computer without a mouse
or a touchpad (“laptops mouse”) as you can
navigate with just the keys but that may be a little
tricky for the average person.

6. The First Mouse
The first mouse was designed 1970
in the U.S. by Douglas Englebart
and constructed by Bill English in
1972.

7. Mechanical Mouse:
This type of mouse was the first one around which uses a
moving ball inside to work. As you move the mouse
across a surface, the ball moves too. Two rollers are also
inside the mouse which track the horizontal and vertical
movement of the ball.

8. Optical Mouse:
The most common type of mouse in use today. This
mouse uses optical technology, so it doesn‟t require
moving parts. The LED light inside the mouse, reads the
pattern or grid on the surface.

9. Laser Mouse:
This mouse works very similar to the optical
mouse, but produces better results. Laser mice
can work flawlessly on any type of surface.

10. 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 you see on the screen, and also
eliminated the use of mouse pads.
•A „scroll wheel‟ is also available on most mouses, making it easier to view web
pages and folders.
