7. Alivn/GAME Lab./CSIE/NDHU Motion Doodles: An Interface for Sketching Character Motion7 Sketch Segmentation

8. Alivn/GAME Lab./CSIE/NDHU Motion Doodles: An Interface for Sketching Character Motion8 Gesture Vocabulary

9. Alivn/GAME Lab./CSIE/NDHU Motion Doodles: An Interface for Sketching Character Motion9 Motion Synthesis Employ a parameterized keyframe-based motion synthesis.

10. Alivn/GAME Lab./CSIE/NDHU Motion Doodles: An Interface for Sketching Character Motion10 Sketching in 3D Position the camera that covers the desired workspace in its FOV. The 3D character is modelled in advance. The 2D sketch segmentation points are back-projected into 3D scene.

11. Alivn/GAME Lab./CSIE/NDHU Motion Doodles: An Interface for Sketching Character Motion11 Sketching in 3D Motion moving directly towards or away the camera is difficult to sketch. Some gestures become ambiguous. 2 difference : foot placement and direction smoothing.
