For data creation of 3D animation, mainly three processes
are required; 1) creation of 3D motion data (we call the data
“3D animation” in the rest of the paper), 2) definition of a
state transition graph for 3D animations and 3) definition of
gestures to call the corresponding animations to play. To
make the process simple and easy, we propose a technique
using an off-the-shelf realtime range sensor and efficient GUI.
