▶️ Demo Video

NicheApple is a tiny real-time face-reaction toy. It uses a webcam feed and MediaPipe Face Mesh to classify a few simple expressions and swaps an on-screen apple sprite accordingly.

Features

• Neutral – baseline calibrated from your face.
• Tongue-Out (closed lips ok) – detects a protruding tongue without requiring a wide open mouth.
• Shock – big mouth + brows/eyes up.
• Cry – mouth corners pulled down with a neutral mouth opening.
• One-key Recalibration – press c for a quick neutral recalibration (~2s).
• Camera Switching – press [ and ] to cycle cameras at runtime.
• Lightweight Logging – periodic metrics print to the terminal for quick tuning.

⚠️ I may add a “mad/angry” expression in a future update. For now, please enjoy the current set—and feel free to contact me if you hit any issues.
