In this paper, we propose a novel interface for controlling crowd animation. Crowd animation is widely used in movie production and computer games. However, to make an intended crowd animation, a lot of agent model parameters have to be tuned through trial and error. Our method estimates crowd parameters based on a few example paths given by a user through a sketch-based interface. The parameters include guiding paths, moving speed, distance between agents, and adjustments of the distance (crowd regularity). Based on the computed parameters, a crowd animation is generated using an agent model. We demonstrate the effectiveness of our method through our experiments.
