Motion Generation Considering Physical Consistency

fig.1 Intuitive Interface

Outline

UTPoser is an inverse kinematics algorithm which provides the user with an intuitive interface shown in Figure 1. The user can pin any number of links and drag a link to generate natural motions or postures of a human figure.
We divide the constraints into two priority levels to avoid the singularity. This algorithm is implemented as the computational engine of SEGA|Animanium(TM).
