🧠 NeuroVision — Eye-Gaze Virtual Keyboard

Type using only your eyes — gaze left or right to pick a keyboard half, then blink to select a letter.
Built with MediaPipe FaceMesh, Python, and OpenCV. No hands required.

⚙️ How It Works

1. Your webcam captures a live video feed.
2. MediaPipe FaceMesh detects 468 facial landmarks in real-time.
3. Iris position is tracked to detect gaze direction (left or right).
4. A LEFT / RIGHT menu appears — hold your gaze on one side for ~1 second to pick that half of the keyboard.
5. The keyboard scrolls through letters one at a time, highlighting each key.
6. Blink when your target letter is highlighted — hold the blink for ~6 frames to type it.
7. < = Backspace, _ = Space.
8. Typed text appears live on the Board window below.

🖥️ Software Setup

1. Clone the Repository

git clone https://github.com/LIKTHANSH/NeuroVision_KeyBoard.git
cd NeuroVision_KeyBoard

2. Install Dependencies

Make sure you have Python 3.8+ installed.

pip install -r requirements.txt

3. Run

python software/virtual_keyboard.py

Note: Sound files (sound.wav, left.wav, right.wav) must be in the sounds/ folder.
If they are missing, the program still runs — just without audio feedback.
