We present an approach for generating a character's response in anticipation of an impending impact. Protective anticipatory movement is built upon several simple actions that have been identified as response mechanisms in monkeys and in humans. These actions are parameterized by a model of the interaction based on the approaching object (the threat) and are defined in procedural rules according to heuristics. We guid the character to perform these actions while obeying physical limits for balance and maintaining characteristics taken from the behavior just prior to the interaction, in our case, a motion caputre sequence. We combine our anticipation model with a physically-based dynamic response to reproduce animations where a character anticipates an impact before collision and reacts to the contact after the collision. We present a variety of examples including threats that vary in approach direction, size and speed. |
