Visi On (also known as VisiOn) is an operating environment for IBM PCs and compatibles running DOS, developed by VisiCorp and released in December 1983. Visi On was the first piece of software with a graphical user interface (GUI) for the IBM PC platform.[1] It was also one of the first GUIs available on any personal computer. Visi On was never popular, as it had steep minimum system requirements for its day, but it was influential in the development of later GUIs like Microsoft Windows.
VisiCorp had programs for sale that were compatible with VisiOn, including a spreadsheet program called "VisiOn Calc". (Not to be confused with VisiCalc).[2][3]
One of Visi On's features was an hourglass cursor that indicated when the system was loading data from a disk. At the time, most software would display words on the screen like "busy" or "please wait" instead.[3]
