The document discusses using facial tracking with AI and WebXR to create a pseudo-3D representation. It provides steps to download sample files and setup, then explains using MediaPipe and TensorFlow to implement real-time facial recognition and link the camera position to the detected face position, creating a sense of 3D. Code snippets are included to initialize the model, start face tracking each frame, and display the 3D scene and camera video feed.
