However, timing is critical to make the character’s action appear realistic. To control the time before the character begins its active response to the impact, we introduce a deliberate delay before changing the desired values tomatchthetransition-toclip. Withasmallornodelay,thecharacter appears to be anticipating the contact and with a large one, the character responds more slowly, as if stunned. With the proper delay time (0.1-0.2 s, which falls in the range of real human response delays), we found that the character’s response to the interaction became much more believable. Since the controller acts while the impactishappening,oursystemcreatesbothactiveandpassivedynamic response simultaneously.
