Face Mocap app is a face motion tracker, is able to detect facial gestures/expressions and head translation/rotation.

This app uses your camera to track a face and send the tracked data to your computer. You may implement a control for animated characters on a game engine like Unreal Engine, Unity or any other software. You can also implement a control for a flight simulator to move the camera with the head.

The data is sent using tcp, data are plain strings with no encription, you can use any tcp client to connect to FaceMocap App. The app listens for tcp clients and sends data each execution frame,
