ArBrush is a simple desktop app (Electron + Python) that lets you draw in the air using your hand in front of a webcam.
Hand tracking is powered by MediaPipe Hands (JS).
- Pinch (index + thumb together) — draw a line.
- Fist — erase an area under your hand.
- Video is mirrored for natural interaction.
- You can adjust stroke thickness and save your drawing as PNG.
This project demonstrates how to combine hand gesture tracking (MediaPipe) with an Electron interface and a lightweight Python server for saving images. It serves as a foundation for more advanced gesture-controlled interactive apps.
