Triggering Artwork Swaps for Live Animation

Abstract: Live animation of 2D characters is a new form of storytelling that
has started to appear on streaming platforms and broadcast
TV. Unlike traditional animation, human performers control
characters in real time so that they can respond and
improvise to live events.
Current live animation systems provide a range of animation
controls, such as camera input to drive head movements, audio for
lip sync, and keyboard shortcuts to trigger discrete pose changes
via artwork swaps. However, managing all of these controls during a
live performance is challenging.
In this work, we present a new interactive system that specifically
addresses the problem of triggering artwork swaps in live settings.
Our key contributions are the design of a multi-touch triggering
interface that overlays visual triggers around a live preview of the
character, and a predictive triggering model that leverages practice
performances to suggest pose transitions during live performances.
We evaluate our system with quantitative experiments, a user study with
novice participants, and interviews with professional animators.
