Abstract: This paper presents an interactive motion-editing method for human animation. Through sketches, users are able to create a 3D skeleton model without any constraints. Then motion retargeting is used to adapt the original motion to the model obtained from the sketches. For supporting expression of intention, our method provides users with direct manipulation of the key parts of the model and uses inverse kinematics to update the gesture. Finally, a new motion is created by smoothly propagating the motion displacement to neighbour frames by linear interpolation. Experimental results prove the effectiveness of the proposed method.

Keywords: motion editing; 3D skeleton modelling; motion retargeting; inverse kinematics; trajectory editing; human animation; interactive editing.
