software to interface easily with a computers input and output devices.
Although he recognized the need for change, it was several years before Bill
Gates and Microsoft Corporation would take action.
At .A 1982 computer convention, VisiCorp Corporation demonstrated a
software interface called VisiOn. VisiOn contained many of the operating
system changes Gates had imagined. In response to VisiOn, Microsoft
Corporation began the development of what was called the Interface Manager .
A design team was formed and announcements were made that Microsoft was
working on a product superior to VisiOn.
The graphical user interface concept used to develop the Interface Manager
was a descendent of the experimental versions of the graphical user interface
from Xeroxs Palo Alto Research Center
