The computer mouse as we know it today was invented and developed by Douglas Englebart during the 60's and was patented on November 17, 1970. While creating the mouse, Douglas was working at the Stanford Research Institute, a think tank sponsored by Stanford University, and originally referred to the mouse as a "X-Y Position Indicator for a Display System." This mouse was first used with the Xerox Alto computer system in 1973. However, because of its lack of success the first widely used mouse is credited to being the mouse found on the Apple Lisa computer. Today, the mouse is now found and used on every computer.

The picture to the right was taken by Maracin Wichary at the New Mexico Museum of Natural History and Science, and is an example of what the first computer mouse looked like. As can be seen by the picture, the mouse was much larger than today's mouse, square, and had a small button in the top right corner.

Doug Engelbert invented the first mouse on 1963-1964 together with Bill english as a combined investor. During that time, it has only one button. Engelbert invented this mouse in the SRI labs. The first mouse, a bulky device with two wheels at right angles and the rotation of each is rendered on one axis.

On November 17, 1970,  Engelbert got a patent of $3,541,541 for the X-Y position Indicator For a Display System. However, in 1968 Telefunken (a German company) distributes their demo. In 1984, it was improved by an updated version of the fundamental Lisa mouse. And right after that, they added LED and up to this moment, it becomes better and faster and it is called as Optical Mouse. We can even control this optical mouse even from afar by means of Bluetooth connection.

Well it is indeed a great invention - Computer Mouse. The thing about technology is that it isn't stable, it never remains fixed but it just keeps on running, sprinting will be the correct word. The mouse which was invented by him, if we compare it with today's mice, we really won't recognise it as a mouse at all.
