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 guide 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 capture sequence.
We combine our anticipation model with a physically-based dynamic response
to produce 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. |
