History of the graphical user interface In the 1960s, Douglas Engelbart's Augmentation of Human Intellect project at the Augmentation Research Center at SRI International in Menlo Park, California developed the oN-Line System (NLS). This computer incorporated a mouse-driven cursor and multiple windows used to work on hypertext. Engelbart had been inspired, in part, by the memex desk-based information machine suggested by Vannevar Bush in 1945.
