🏃♂️VR Full-Body Tracking with XSens DOT Trackers [WIP]
❗This project currently is in active development!
Core tracking and rotation mapping are implemented. I am currently validating position and scaling from test objects to a full body rig.
What it Does:
Full Body tracking for Meta Quest using Xsens DOT trackers inside Unity.
The project streams live motion data from multiple Xsens DOT trackers over Bluetooth LE into a standalone Quest build, then maps that data onto in game objects and a body rig to drive full body movement.
Key Features & Challenges:
- Feasibility first: proved that the entire idea is possible and that trackers can indeed connect to the Meta Quest through Bluetooth by getting a single tracker connected with the example XSens app.
- Bluetooth LE integration in Unity: used a Unity BLE package to scan, connect, subscribe to notifications, and handle reconnects on Quest.
- Services and characteristics: learned and implemented the BLE model to find the right services and characteristics, then subscribe to the correct data streams.
- Decoding live sensor output: extracted usable orientation and motion data from the incoming packets and built debug tooling to validate correctness.
- Rotation mapping and calibration: solved coordinate space and quaternion issues so the cube rotation matches the real tracker, including offsets and axis remapping.
- Position tracking work in progress: exploring approaches for positional movement, dealing with IMU drift, filtering, and reset strategies.
Impact on the Project:
- Established a working pipeline from Xsens DOT to Quest in Unity, de risking the technical unknowns early.
- Produced a solid rotation mapping foundation that can be reused for multiple trackers and avatar bones.
- Defined clear next steps for position by narrowing the problem to drift and reference constraints, guiding the roadmap towards IK or hybrid anchoring.
📽️ Unity Video-to-FBX Converter Tool
What it Does:
Video-to-FBX converter is a tool which can convert multiple videos (mp4, mov) to an FBX animation all within Unity using MoveAI.
Key Features & Challenges:
- MoveAI API Intergration: the tool converts videos using MoveAI’s API by launching a custom-made Python script in Unity.
- Clear user interface: the tool provides an easy-to-use UI for a frictionless workflow.
- Parallel Conversion: the tool uses Unity’s tasks system to run multiple conversions at the same time.
- User feedback per task: each task provides clear feedback on the job’s status and progress.
- Runs in the background: the tool runs in the background and doesn’t disturb regular editor workflows.
Impact on the Company:
- Simplified the workflow for the senior programmer from a three-step operation (uploading videos to MoveAI, downloading the FBX, importing to Unity) into a one-click operation all within Unity, saving a lot of time.
- Improved user feedback by providing clear status and progress per video within Unity, giving reassurance and understanding to the user.
- Allowed for multiple video conversions in parallel, turning from a 15-minute consequitive conversion for 3 videos into a 5-minute parallel conversion for 3 videos (and more).
