Virtual Hand Gesture Calculator

This project is a Virtual Calculator that uses hand gestures to interact with the calculator. In this no mouse or keyboard is needed! It uses your webcam, detects your hand using MediaPipe (via cvzone), and allows you to press calculator buttons with just your fingers.

How It Works

• Your webcam captures live video.
• The program detects your index and middle fingers.
• When your index and middle fingers touch (distance < threshold), it's treated as a "click".
• If your fingertip is over a button, it's considered pressed.
• The result or ongoing equation is shown at the top of the screen.
