Here is source code for an example of hand tracking application (Virtual calculator) using openCV and mediapipe. It is a project for practicing skills in using openCV and image processing in computer vision. With this code, you can create a Virtual calculator and do basic mathematical calculation.

A virtual calculator is a software-based calculator that allows users to perform mathematical operations using a graphical user interface (GUI) or voice commands. It can be implemented using various programming languages such as Python.

The Hand Calculator is an interactive Python application that allows users to perform basic arithmetic operations using hand gestures captured via a webcam. It leverages computer vision techniques to detect and count fingers for inputting numbers (0-5) and recognizes specific hand gestures to select mathematical operations.
