Animating armatures using traditional 3D modelling and animation packages is complex and difficult for novice users to use. A sketch-based articulated figure animation tool is introduced that provides users with an intuitive interface to pose and animate armatures of any topology easily. An isomorphic mapping between the sketch and the armature is determined and a recursive algorithm poses the armature so that it matches the pose sketched. It is shown how sketch- and depth ambiguity can be resolved using disambiguation information and pressure sensitivity. The tool developed allowed novice users to successfully and easily sketch stick figures to pose articulated figures for sketch-based animation.
