MoveBox is a toolbox to animate the Microsoft Rocketbox avatars (https://github.com/microsoft/Microsoft-Rocketbox) using motion captured in three different ways. Each form of avatar animation is presented as a separate project: a capture studio, an IK and Hand tracking tool for realtime use, and an offline video tracking plugin.
Watch the presentation of the tool at IEEE AIVR:

Reilly, Tabitha C Peck, Andrea Stevenson Won, Anthony Steed and Eyal Ofek (2020) "MoveBox: Democratizing MoCap for the Microsoft Rocketbox Avatar Library". IEEE International Conference on Artificial Intelligence and Virtual Reality (AIVR) Paper
We created a Motion Capture (MoCap) studio using a single depth sensor, such as Azure Kinect or Windows Kinect V2. Our toolbox enables real-time animation of the user's avatar by converting the transformations between systems that have different joints and hierarchies. Additional features of the Captire Studio include recording, playback and looping animations, as well as basic audio lip sync, blinking and resizing of avatars. Our main contribution is both in the creation of this open source tool as well as the integration of MoveBox with Kinect V2 and Azure Kinect, as well as the interfacing with the Microsoft Rocketbox avatars.
Using an off the shelf HMD we recover realtime motions to create avatar embodiment. The hand and head positions and rotations of the user are transferred to a Microsoft Rocketbox Avatar of your choice. All in realtime. The hand tracking is used for an Inverse Kinematics (IK) solver (included) that reconstructs a possible elbow position. Our demo project also includes finger tracking for the Oculus Quest.
Movebox can parser the SMPL body models extracted by an external tool for 3D multi-person human pose estimation from RGB videos. We utilized a deep-learning based approach open sourced as VIBE (https://github.com/mkocabas/VIBE), which trains a temporal model to predict the parameters of the SMPL body model for each frame while a motion discriminator tries to distinguish between real and regressed sequences. NOTE: the VIBE repo has a research only license and you should check if your project can use it (https://github.com/mkocabas/VIBE/blob/master/LICENSE) The output of the model is a sequence of pose and shape parameters in the SMPL body model format (https://smpl.is.tue.mpg.de/). To animate Microsoft RocketBox avatars with predicted 3D poses, the toolbox first extracted the joints data from pose parameters, computed the transformation between SMPL and RocketBox skeleton structures, and then mapped to the corresponding joint in the Microsoft RocketBox avatar skeleton.
Note: Tools from the capture studio (MoveBox) can be imported to project 2 if there is a need to record the motions of the participant or user for later use.

Open the MoveBox_CaptureStudio project in Unity. Open the Visual Studio Solution associated with this project "MoveBox_CaptureStudio.sln". If there is no Visual Studio Solution yet you can make one by opening the Unity Editor and selecting one of the csharp files in the project and opening it for editing. You may also need to set the preferences->External Tools to Visual Studio
In Visual Studio: Select Tools->NuGet Package Manager-> Package Manager Console
On the command line of the console at type the following command:
Install-Package Microsoft.Azure.Kinect.BodyTracking -Version 1.0.1The body tracking libraries will be put in the Packages folder under MoveBox_CaptureStudio
You can do this by hand or just run the batch file MoveLibraryFile.bat in the MoveBox_CaptureStudio directory

Open the Unity Project and under Assets\Microsoft Rocketbox MoveBox\Scenes select the MoveBox_CaptureStudio Introduce the Microsoft Rocketbox avatar into the scene Attach the MoveBoxPlayback script if you are reproducing exising animation Or select the avatar parent in the MoveBox script on the MoveBox gameobject for realtime capturing and/or recording. On the inspector select whether you use a Kinect v2 or an Azure Kinect
Press play.
MoveBox_IKHandTracking enables users of VR headsets to embody their rocketbox avatars and use their controllers to control the avatar motions in realtime from their HMD. We extrapolate the position of the upperbody (head and arms) based on the head and the hand-controllers positions and rotations. The demo also has finger tracking implemented for users of Oculus Quest.
Using an external tool we can retrieve the skeletons from archival footage and convert them to animations for the rocketbox avatars.
