GreenMagic – Air Writing & Gesture Graphics

This repo contains the GreenMagic air-writing system. The main app lives in air_writing_system/.

Quick start

# From repo root
cd air_writing_system
python -m venv venv
./venv/Scripts/python.exe -m pip install -r requirements.txt
./venv/Scripts/python.exe air_writing_enhanced.py

For a minimal finger-tracking demo:

cd air_writing_system
./venv/Scripts/python.exe test_air_writing.py

Key features

• Real-time index fingertip tracking (MediaPipe HandLandmarker)
• Air-writing laser trail and smoothing
• Close-fist gesture to finish and trigger OCR
• OCR-driven text recognition → AI graphics generation and overlay
• Voice feedback, logging, analytics modules
