disconnected gesture demo →

Run the bridge on this PC — Windows: py -3 bridge.py · macOS/Linux: python3 bridge.py. (Not python bridge.py on Windows — see “Get the bridge”.)
Start camera below and allow webcam access.
OpenTrack: Input = UDP over network (port 4242), Output = your game.
Tune the axes, Recenter, and save a preset.

Status: disconnected bridge not reached · connecting trying (start the bridge) · streaming sending pose. A console ws://127.0.0.1:8765 failed just means the bridge isn’t up yet — it retries.

Your video never leaves this device. Only six pose numbers are sent, and only to your own PC over ws://127.0.0.1.

Get the local bridge

Run this on your gaming PC (needs Python 3.8+, no install). Start it from the bridge/ folder:

py -3 bridge.py      # Windows
python3 bridge.py   # macOS / Linux

On Windows, don’t use python bridge.py or bare py bridge.py — the Microsoft Store “App execution alias” intercepts them and the bridge never starts. py -3 avoids that.

It should print waiting for browser.... Then in OpenTrack pick input UDP over network (port 4242) and your usual game output.
