Air Writing Recognition Using Mediapipe and Opencv

Abstract

Have you ever wished you could draw something just by waving your finger in the air? This can be accomplished in this day and age using a variety of technologies. This paper describes an application that uses the Python modules MediaPipe, Numpy, and OpenCV to write/draw geometrical shapes in real time over air in front of a camera. The proposed method accomplishes two goals: first, it recognizes the hand and the fingers from video frames, and then it monitors hand movements to create diverse designs. Furthermore, this technology allows for genuine Human-System interaction without the use of any form of character input device. The application is created in Python and tested in a variety of circumstances with variable illumination. This Software-based solution is relevantly basic, quick, and straightforward to use.
