NaturalMotion's Active Character Technology (A.C.T.) is based on Oxford University's research on the control of human and animal body motions. In essence, we build a physical, biomechanically-realistic model of a character (e.g. a human or a dinosaur), implant an appropriate brain structure (usually a neural network), and use optimisation techniques (such as artificial evolution) to create the desired behaviour.
