Core Concepts
A novel machine learning model and interactive visualization tool that enables artists to generate and explore diverse 3D human motion sequences based on fine-grained attribute descriptions.
Abstract
The paper introduces a design tool for artistic performances based on attribute descriptions, focusing on the dynamics of falling movements. The researchers collected a unique dataset featuring complex labeling of falling actions, characterized by a new ontology that divides motion into three distinct phases: Impact, Glitch, and Fall.
The core of the approach is an Attribute-Conditioned Variational Autoencoder (AC-VAE) model that can learn these phases separately and generate realistic 3D human body motions from the motion capture data. The model employs a cyclic design, where the last frame of the generated video is used as the initial guiding pose for the next phase, contributing to the accurate representation of each phase.
The researchers also developed an interactive web-based interface that allows artists to manipulate the generated 3D motions with fine-grained control over motion attributes and visualization tools, including a 360-degree view and a dynamic timeline for playback manipulation. This platform aims to amplify the creative potential of human expression and make sophisticated motion generation accessible to a wider artistic community.
The paper presents a unique collaboration between artists and computer scientists, where the artist's creative vision drives the development of the machine learning model. The resulting tool offers new creative possibilities for falling animations, which could be extended to various other choreographed motions.
Stats
"We collected approximately 150 trials of the artist performing dramatic falling actions labeled with these attributes and granular sub-definitions of expressive motion."
"Unlike previous works, the falling movement is complex and has multi-phase labels."
