Radial Menus, Release to Select

Engaget recently covered the release of a new mobile device by Enblaze. I like the radial interface, and the move away from buttons, which in my opinion is one of the weakest interactions of a touch screen. Some downsides of this approach include

• accidental triggering of features when you lose your grip momentarily
• Bias or inefficiency (unless it automatically switches) to switch between left and right hands
• Loss of spatial memory
• Loss of the visual efficiency in vertical and horizontal grid alignment
