fog: Generating Expressive Motion through Layered Function Composition of Code for Heider-Simmel Animation

Abstract:Motion and emotion are core parts of intelligent, expressive behavior. In this paper, we introduce fog, a layered function composition framework for generating motion functions. We demonstrate how fog can be used to express motion and emotion in Heider-Simmel style animations. This code generation framework can help users generate functions for verbs, adverbs, and emotions to capture the trajectory, manner, and feeling of motion. It is complemented by an animation editor that helps users provide spatial context in the form of marks, arrows, and paths. We evaluate our approach with a technical evaluations investigating different function generation and composition setups. In a mixed-methods user study (n=12), we find that fog can support users can support users by relaying spatial context they mark and draw and giving them more dimensions for control.
