Sony mocopi Pro Kit

The Sony mocopi Pro Kit is a lightweight, wearable motion capture system designed for rapid full-body motion capture without the need for external cameras or fixed studio installations. The system uses multiple compact IMU-based sensors worn on the body, enabling fast setup and portable capture in labs, studios, classrooms, or field environments.

Motion data is processed using XYN Motion Studio, which provides tools for pose reconstruction, motion cleanup, retargeting, and export. The software supports common animation and real-time engines, allowing captured motion to be applied directly to digital characters, avatars, or simulation models with minimal post-processing.

Captured motion can be exported in standard formats such as FBX and BVH, enabling integration with Unity, Unreal Engine, Blender, and custom biomechanics or robotics pipelines. This makes the system suitable for both real-time XR embodiment and offline analysis workflows.

Typical use cases include character animation, XR embodiment and avatar control, virtual production prototyping, biomechanics and movement studies, sports and performance analysis, and human–computer interaction research.

Compared to camera-based optical systems, mocopi prioritizes mobility and fast iteration. While IMU-based capture may exhibit drift or reduced absolute accuracy over long sessions, it enables motion capture in environments where optical systems are impractical or impossible.

Development & Research Advice: Validate sensor placement consistency before long recordings and test retargeting with simple avatar rigs before moving to complex characters. When combining mocopi with eye tracking or biosensing, synchronize data streams at the software level using timestamps or a shared clock rather than relying on post-hoc alignment.
