OG Emoji Reactor

About

Uses MediaPipe's Face Mesh and Pose detection to track your expressions and body language through your webcam in real time. The app overlays matching emojis on screen as you move — a smile triggers 😊, raising both hands shows 🙌, and a straight face defaults to 😐. Built entirely in Python with OpenCV for video capture. Fully customizable: swap in your own emoji images or adjust detection thresholds. An original project that proves computer vision can be fun.
