Why Tracking Data Export Works Here
Vis Exo isn't only a visual effects tool — every tracking mode produces structured, per-frame data alongside whatever's rendered on screen: an ID, position, size, and velocity for each tracked object. That data can be exported as a CSV file once tracking finishes, or streamed live as JSON over a WebSocket while it's running. Useful for movement research, sports/dance motion analysis, generative-art pipelines in Processing or p5.js, or feeding a live installation controller.
Frame-by-frame CSV export
One row per frame per tracked object — ID, center X/Y, bounding box width/height, and velocity — downloadable once a recording or analysis pass finishes.
Live JSON over WebSocket
The TouchDesigner / OSC panel broadcasts the same data live instead of waiting for an export, for anything that can open a WebSocket client.
Works across all 7 modes
Blob, Motion, Face, Object, Pose, Person, and Hand tracking all export data the same way — not a feature limited to one mode.
Built for research and analysis
Plain CSV/JSON drops straight into a spreadsheet, Python/pandas, or any other tool that reads structured data — no proprietary format.
Also feeds TouchDesigner, Max/MSP & Ableton
See the TouchDesigner Alternative guide for the OSC/WebSocket streaming side of this in more depth, including a ready-to-paste receiver script.
Nothing leaves your device
Detection and data export both run entirely client-side via WebAssembly — no video or photo is ever sent to a server to generate the data.
Frequently Asked Questions
What data is included in the CSV export?
Frame-by-frame telemetry for each tracked object: an ID, center X/Y coordinates, bounding box width/height, and velocity, one row per frame.
Can I stream tracking data live instead of exporting a file afterward?
Yes — the TouchDesigner / OSC panel broadcasts the same per-object data live as JSON over a WebSocket, so a tool like TouchDesigner, Max/MSP, or Ableton (via Max for Live) can consume it in real time instead of waiting for a CSV file.
Does data export work for object detection and pose data, not just blob tracking?
Yes — CSV and live streaming export work the same way across all seven tracking modes: Blob, Motion, Face, Object, Pose, Person, and Hand.
What can I use the exported tracking data with?
Any tool that reads CSV or JSON — spreadsheets, Python/pandas for research analysis, Processing or p5.js for further visualization, or TouchDesigner/Max/Ableton via the live OSC/WebSocket stream.
Is my video uploaded anywhere to generate the tracking data?
No. Detection and data export both run entirely in your browser — no video or photo is ever sent to a server.
