O rato “Embora tenha sido inventado por Bill English, a sua patente pertence a Douglas Engelbart, com a patente nr. 3.541.541 nos EUA datando de 1970.
Engelbart apresentou este periférico pela primeira vez em 9 de dezembro de 1968 denominando-o de “XY Position Indicator For A Display System”. Constituía-se então em uma pequena caixa de madeira com apenas um botão. O invento de Engelbart ficou sem muita utilização devido a falta de necessidade de tal dispositivo. Afinal a maioria dos computadores utilizavam apenas textos sem cursores na tela.”

The Xerox Star Workstation introduced the first GUI Operating systems.
Engelbart’s work directly led to the advances at Xerox PARC. Several people went from SRI to Xerox PARC in the early 1970s. In 1973, Xerox PARC developed the Alto personal computer. It had a bitmapped screen, and was the first computer to demonstrate the desktop metaphor and graphical user interface (GUI). It was not a commercial product, but several thousand units were built and were heavily used at PARC, as well as other XEROX offices, and at several universities for many years. The Alto greatly influenced the design of personal computers during the late 1970s and early 1980s, notably the Three Rivers PERQ, the Apple Lisa and Macintosh, and the first Sun workstations.
The GUI was first developed at Xerox PARC by Alan Kay, Larry Tesler, Dan Ingalls and a number of other researchers. It used windows, icons, and menus (including the first fixed drop-down menu) to support commands such as opening files, deleting files, moving files, etc. In 1974, work began at PARC on Gypsy, the first bitmap What-You-See-Is-What-You-Get (WYSIWYG) cut & paste editor. In 1975, Xerox engineers demonstrated a Graphical User Interface “including icons and the first use of pop-up menus”.[3]
In 1981 Xerox introduced a pioneering product, Star, incorporating many of PARC’s innovations. Although not commercially successful, Star greatly influenced future developments, for example at Apple, Microsoft and Sun Microsystems.[4]

Xerox Alto and Xerox Star[edit source | editbeta]
The Xerox Alto (and later Xerox Star ) was an early personal computer developed at Xerox PARC in 1973. It was the first computer to use the desktop metaphor and mouse-driven graphical user interface (GUI).
It was not a commercial product, but several thousand units were built and were heavily used at PARC, other Xerox facilities, at least one government facility and at several universities for many years. The Alto greatly influenced the design of some personal computers in the following decades, notably the Apple Macintosh and the first Sun workstations.
