THE MOUSE
The mouse has been since its first appearance a vital part of the pc, in these days we can’t imagine a
desktop pc without a mouse but very few people knows how or when this appears.
1952: Born the first trackball, invented by the Canadian NAVY
1963: The first mouse prototype appears, invented by Douglas Engelbart: Consisted of a wooden
shell, circuit board and two metal wheels that came into contact with the surface it was being used on.
1970: The mouse appears on the market: “X-Y Position Indicator for a Display System” worked
with two gears that recorded horizontal and vertical cursor positions.
A few weeks after submitting Engelbart, the German company Telefunken launched a mouse model
that had a small rubber ball inside, responsible for recording the coordinates. Although the device was
part of the computer components brand, that was regarded as the first commercially available mouse
history.
1973 – 1981: The Xerox mouse: The following mouses that won the market were sold with Xerox
personal computers, such as Alto, 1973, the first computer to use as desktop which had a usage-based
"mouse”.
1983: The first apple mouse: In 1983, Apple launched the famous Lisa computer, which included a
mouse. A salient feature of this model is that instead of using a rubber ball, mouse Lisa wore a metal
sphere. This was the model that set the standard of a single button mouses for all of the company for
nearly 20 years.
1999: Optical mouse is released: Although research in 1980 this technology was in 1999 that came
the first commercial model of this type. The IntelliMouse with IntelliEye of Microsoft, worked on
almost any surface and showed significant improvements compared with the mechanical mouse.
The main difference was that the "ball" of the mechanical mouse was replaced by an infrared LED,
with the advantage that this model did not accumulate dirt, preventing the user having to open the
device for cleaning. The IntelliMouse series was the first to incorporate the scroll Wheel

Later, these models have continued to evolve and the LED was replaced by a laser, invading the
market in 2004.
The evolution of mouses does not end there, now incorporated mouses gyroscopes, allowing it
unnecessary to use on a flat surface physic. These types of models require only some small
movements to move the cursor, thereby reducing physical fatigue caused by dragging the mouse all
day.
Another innovation are called 3D mouses, specially developed for editing and navigation of images in
three dimensions , but are not limited to such use.
Also emerged new models to which they can add their effects generated sensations, such as vibrate
cause the device to be the cursor over a graphical element.
It is necessary to mention a device like the Kinect, Xbox 360, which can guide the development of
future mouses, wherein it is not necessary to take any element by hand to move the cursor.
As we can see, may be the mouse is condemned to disappear but only as a external device all the
functions and apps for this device keep appearing in many ways.
