Recently, use of a computer becomes common and it has spread as a tool useful for anyone. In the background, there is development of the user interface for computer operation. Also in user interface, a mouse interface is famous. The mouse interface was developed for the first time by
Douglas Carl Engelbart in 1961. Various mouse interfaces in which a design and convenience were considered were developed. A mainstream mouse interface has three functions, “Left-click”,
“Right-click” and “Cursor movement”. Currently, a mouse interface with these three functions is in use. However, these mouse interfaces have operation restrictions. It is that a flat place is indispensable. From this, we think that there is big interest in a new mouse interface with the basic function of the mouse without needing operation restrictions of the existing mouse interface. In this paper, we propose the new mouse system with a different concept by using the Augmented Reality, and develop a prototype system.
