Performance-based method for 2D character animation

Performance-based animation has received significant attention because of its naturalness,intuition,and its easy-to-use for novices and non-professional animators.However,most existing performance-based systems either require special and expensive device or can only animate low degree of freedom objects such as a rigid body.This paper presents a new performance-based animation technique for novice animators and develops a 2D character animation system.It uses a pen as the prop and maps its movement to the character in real-time,the character's motion is recorded to form an animation.The evaluation result shows that the system lowers the barrier of animation authoring and allows novices to create animation simply and quickly.
