“…Dontcheva et al [14] enabled the animator to author character animations by imitating the movement under a customized Mocap system. Besides, the large scale Mocap databases have been constructed by many research institutions and companies [1], [2], and many works to generate motion sequences using the Mocap databases have been proposed [15], [16]. Then, we take a "data-driven" approach but consider (i) how to intuitively find motion data from the database and (ii) how to edit motion data for our needs.…”

“…Similarly, right-shoulder node, lower-neck node and their child nodes are allowed to be reassigned when the related movement is modified. The similar approach is applied by Iwamoto et al [16] which they segmented the hands movement and body motion to synthesize the dance motion sequence. Although this approach seems to work well, other methods can also be used in our framework.…”

Animating 3D characters using motion capture data requires basic expertise and manual labor. To support the creativity of animation design and make it easier for common users, we present a sketch-based interface DualMotion, with rough sketches as input for designing daily-life animations of characters, such as walking and jumping. Our approach enables to combine global motions of lower limbs and the local motion of the upper limbs in a database by utilizing a two-stage design strategy. Users are allowed to design a motion by starting with drawing a rough trajectory of a body/lower limb movement in the global design stage. The upper limb motions are then designed by drawing several more relative motion trajectories in the local design stage. We conduct a user study and verify the effectiveness and convenience of the proposed system in creative activities.
