Multi-Touch Menu (MTM)

This paper describes a new menu technique called Multi-Touch Menu, that is especially well suited for multi-touch ineractive surfaces. In contrast with traditional menu techniques, the Multi-Touch Menu makes the most of new capabilities provided by these new interactive devices: instead of only using two degrees of freedom, it makes it possible to use the five fingers of the hand simustaneously for interacting with applications. By providing several interesting properties, such as eyes-free selection or the ability to navigate seamlessly in the hierarchy of commands, Multi-Touch Menus make it possible to enrich and facilitate interaction on multi-touch devices.
