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.
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.
