I Built Glasses-Free 3D for Web Browsers Using Webcam Head Tracking

The Problem
VR adoption remains low. Headsets are expensive and uncomfortable. But billions of people already have devices with cameras.

The Solution
Use webcam head tracking to create motion parallax depth on regular screens.

How It Works

1. Webcam detects face position
2. Calculate head position in 3D space
3. Adjust camera perspective to match viewer position
