Tracking menus, system and method
Abstract:
The present invention is a system that includes a tracking menu that tracks the movement of a position transducer, such as a stylus or a mouse, as the transducer is moved about in association with a display. The menu is typically displayed on top of other objects in the display. The menu includes a tracking symbol, such as an arrow or cursor, positioned corresponding to inputs from the transducer as it is moved by a user. A mobile tracking region is also included. This tracking region has a tracking boundary or edge enclosing the tracking symbol where the tracking symbol is movable within the boundary or hits without the menu moving. The tracking region or entire menu moves in correspondence to the tracking symbol when the tracking symbol encounters the boundary or hits while the symbol is moving. The tracking region also has menu controls or buttons that are activatable when the tracking symbol corresponds to the controls.
