Abstract:
Nowadays, animation of human interaction is predominantly modelled statically. Animations are adapted manually to each set of participating characters to ensure visual fidelity. To automate this process, we propose a novel procedural animation technique where character interactions are modelled dynamically with fuzzy logic and compare our technique to conventional inverse kinematics. The ’handshake’ interaction is used as an example interaction, in order to illustrate how basic animation rules are defined, while leaving room for parametrization of character specific properties. Our results show that, although inverse kinematics delivers higher precision in positioning than fuzzy logic, they are dependent on paths describing the motion of the final element in the kinematic chain. Fuzzy logic, on the other hand, is independent of such motion paths and solves towards the target location locally. The presented handshake model using fuzzy logic can serve as a basis for future models for v
irtual-human interaction.
