What is a Computer Mouse Who invented it ?
Just what is a computer mouse ?
for many of us it’s simply a tool to control a computer, by manipulating the
computers cursor movement in parallel to the physical movement of the mouse.

History
Who invented the
computer mouse ?
The first prototype computer
mouse is now over 40 years old, it was invented in 1964 by Douglas Engelbart, it
was designed with a wooden shell, and had 2 metal wheels, unlike today the
cable to the computer came from the back of the mouse, hence where the name
mouse came from. Engelbart designed the computer mouse to change the way
computer could be used, up until this point computer were considered to be very
specialized equipment, used only by the like of scientists.

The First Computer Mouse Designed
By Douglas Engelbart " what is a computer mouse "
The computer mouse has
undergone a lot of changes over a relatively short period of time, we have seen
literally all aspects of it changing from the following.
The early mice used a serial
type connection, which at the time was a problem as the port was normally being
used by devices such as printers so computer manufacturers started added
multiple serial ports, usually they would come with a 2, the larger 25 pin type
and the small 9 pin for the mouse.
The next incarnation of the
mouse was the Mini DIN or PS/2 type connector, it now shared the same type of
connecter as the keyboard, but each would only work in it’s own specific port,
so manufacturers started to color code mouse and keyboard connectors to match
the same on the computer, green for a mouse and purple for a keyboard.
Now we move onto the USB
(universal serial bus) standard which is the most common type of connection
around today, when the USB connectors were first introduced there was literally
no devices or peripherals available for them (hard to believe now today) and it
got the nick name useless serial bus.
The big advantage of USB
computer mice is the ease in which a mouse can be installed, generally just plug
in, wait a few minutes and it will be installed and ready to use.
Unlike the older PS2 and serial
technologies a USB mouse can be plugged in and recognized while a computer is
switched in.
Still with the USB standard,
the next computer mouse replaced the mouse ball with a laser which suffers far
less from dirt and grime as picked up on the older types, it also means it works
more accurately when on an adequate surface.
And finally we went wireless,
the original wireless mice used Infra red, the same type as a type or video
remote control, but due to the unreliability of the signal this was soon
replaced by Wireless technologies such as Bluetooth.
New generations of computer
mice have expanded into all directions including shape or ergonomics, novelty,
multiple buttons, plus lots more bells and whistles
So in a very short space of
time, we’ve seen the invention of the computer mouse, the changes in interface,
control systems, and removal of cables, but at the end of the day it still does
the same thing as the original.
