Motion editing often requires repetitive operations for modifying similar action units to give a similar effect or impression. This paper proposes a system for efficiently and flexibly editing the sequence of iterative actions by a few intuitive operations. Our system visualizes a motion sequence on a summary timeline with editable pose-icons, and drag-and-drop operations on the timeline enable intuitive controls of temporal properties of the motion such as timing, duration, and coordination. This graphical interface is also suited to transfer kinematical and temporal features between two motions through simple interactions with a quick preview of the resulting poses. Our method also integrates the concept of edit propagation by which the manual modification of one action unit is automatically transferred to the other units that are robustly detected by similarity search technique. We demonstrate the efficiency of our pose-timeline interface with a propagation mechanism for the timing adjustment of mutual actions and for motion synchronization with a music sequence.
