<P> Early dynamic information devices such as radar displays, where input devices were used for direct control of computer - created data, set the basis for later improvements of graphical interfaces . Some early cathode - ray - tube (CRT) screens used a light pen, rather than a mouse, as the pointing device . </P> <P> The concept of a multi-panel windowing system was introduced by the first real - time graphic display systems for computers: the SAGE Project and Ivan Sutherland's Sketchpad . </P> <P> 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 . </P> <P> Much of the early research was based on how young children learn . So, the design was based on the childlike primitives of eye - hand coordination, rather than use of command languages, user - defined macro procedures, or automated transformations of data as later used by adult professionals . </P>
