History
The first documented radial menu is attributed to a system called PIXIE in 1969. Some universities explored alternative visual layouts.
In 1986, Mike Gallaher and Don Hopkins together arrived independently to the concept of a context menu based on the angle to the origin where the exact angle and radius could be passed as parameters to a command, or the radius could be used to trigger a submenu.
The first performance comparison to linear menus was performed at 1988 showing an increase in performance of 15% less time and a reduction of selection errors.
