ABSTRACT
The seminal work known as Sketchpad [Sutherland 63] by Ivan Sutherland has inspired many researchers in the field of human-computer interaction (HCI) and three-dimensional user interface (3DUI). Sutherland created an elegant and sophisticated system, which is considered by some as the birth of computer user interface studies. The invention of the mouse by Douglas Engelbart in 1963 [English et al. 67] and the invention of the Graphical User Interface (GUI) at the Palo Alto Research Center (PARC) gave way to one of the most successful paradigms in HCI: Windows-Icon-Menu-Pointer (WIMP), which has allowed users to interact easily with computers.
