Start full-body tracking easily on your iPhone.

When you input footage or video from a normal camera, our in-house developed image-recognition AI technology (deep learning) detects 24 body keypoints and outputs them as 3D coordinates with real-time motion capture using the TDPT (ThreeD Pose Tracker) system. This “TDPT system” has also attracted attention through academic presentations, published papers, and joint research.

Publications & Collaborations

Using the coordinates output by the TDPT system, the iOS version of TDPT allows you to manipulate an avatar’s bone rotations so that you can perform full-body tracking with just an iPhone — without attaching trackers to your body. It is widely used for VTuber activities, expressive motion in the metaverse, and more.

The app is free to download, and it also offers optional Premium Menu features available via one-time purchases. The Premium Menu adds functions such as switching avatars from VRoidHub, live streaming, motion data transmission, and export.
