The rapid development of handheld devices is driving the development of new interaction styles. This paper examines one such technique: using hand motions to control a menu system. Previous research on this topic deals with systems which rely heavily on graphical feedback, a disadvantage in many mobile scenarios. Inspired by marking menus, our system is designed to be used "eyes-free" and based on making relatively large scale rotational strokes. We describe the system and an initial evaluation in detail. The results indicate that its performance is comparable to previous motion menu systems, but that this can be attained without visual feedback. This represents a substantial benefit.
