SUMMARY:Control Operators for Interactive Character Animation
DESCRIPTION:Ruiyu Gou (Epic Games), Michiel van de Panne (University of Br
 itish Columbia), and Daniel Holden (Epic Games)\n\nNeural-network-based ch
 aracter controllers are increasingly common and capable. However, the inte
 gration of desired control inputs such as joystick movement, motion paths,
  and objects in the environment, remains challenging. This is because thes
 e inputs often require custom feature engineering, specific neural network
  architectures, and training procedures. This renders these methods largel
 y inaccessible to non-technical designers. To address this challenge, we i
 ntroduce Control Operators, a powerful and flexible framework for specifyi
 ng the control mechanisms of interactive character controllers. By breakin
 g down the control problem into a set of simple operators, each with a sem
 antic meaning for designers, and a corresponding neural network structure,
  we allow non-technical users to design control mechanisms in a way that i
 s intuitive and can be composed together to train models that have multipl
 e skills and control modes. We demonstrate their potential with two curren
 t state-of-the-art interactive character controllers - a flow-matching-bas
 ed auto-regressive model, and a variation of Learned Motion Matching. We v
 alidate the approach via a user study wherein industry practitioners with 
 varying degrees of ML and technical expertise explore the use of our syste
