RingEdit: A Control Point Based Editing Approach in Sketch Recognition Systems

Editing a sketch should be one of the essential features provided by sketch recognition systems to allow people to modify what they have drawn, without having to delete and redraw shapes. This paper introduces a control point based editing approach we call RingEdit. RingEdit differs from other sketch editors in that the user actually draws their own control points on the sketch, rather than relying on control points generated by the recognition system. It provides modes that allow moving, rotating, scaling, and bending on both the shape level and stroke level. RingEdit shows great editing capabilities.
