Abstract
Provided is multi-stroke marking menu techniques that increase menu breath over an eight-item limit of some orientation-based marking menus. Zone and polygon menus can be provided wherein the breadth can be increased by a factor of about two or more while providing quick selection and maintaining selection accuracy. Various geometric attributes can be analyzed to determine a selection stroke. These attributes can include orientation, position, and/or length of each stroke. Hybrid techniques are also disclosed that further increase menu breadth and performance.
