Menus leaf: enrichir les menus linéaires par des gestes

We present a new kind of linear menu based on gesture, called Leaf menu. The Leaf menu is adapted to the selection of commands for the cases of small handheld touchscreen devices (PDA, smartphone): Indeed it supports finger-based interaction, minimizes the required screen space, manages occlusion and can be used close to the screen borders. Moreover the Leaf menu suppports eyes-free selection. It can also be used in the context of a tabletop and of a personal computer by providing an alternative to keyboard shortcuts.
