Learning Two-Person Interaction Models

We address the problem of creating believable animations for virtual humans and humanoid robots that need to react to the body movements of a human interaction partner in real-time. Our data-driven approach uses prerecorded motion capture data of two interacting persons and performs motion adaptation during the live human-agent interaction. Extending the interaction mesh approach, our main contribution is a new scheme for efficient identification of motions in the prerecorded animation data that are similar to the live interaction. A global low-dimensional posture space serves to select the most similar interaction example, while local, more detail-rich posture spaces are used to identify poses closely matching the human motion. Using the interaction mesh of the selected motion example, an animation can then be synthesized that takes into account both spatial and temporal similarities between the prerecorded and live interactions.

Blender Conf 2015 Talk

At Blender Conf 2015 I was honored to talk about our human-character interaction framework. The presentation mainly focuses on extensions we made to Blender including motion capture addons for optical A.R.T. tracking systems and Kinects as well as Matlab bindings to compute character responses.
