Implementation of Real Time Virtual Clicking using OpenCV

Digital devices are presently being used in most of the public places like ATM, ticket booking counters, exit surveys in showroom. The digital devices used in these places needs direct contact with the screen. In pandemic situation what we are presently in, this physical contact paths way for the spread of disease. Use of digital devices without the physical contact is the need of the day. In this work a virtual mouse is proposed which does not need any contact and can be used in public places without any harm. The current technologies both wired and wireless needs a physical mouse for the cursor control. The proposed model made the Human Computer Interface (HCI) technology move to the next stage of development with Hand Gesture Recognition. So this avoids the need of physical mouse. The initial step begins capturing of the image with the inbuilt or external camera. Further the image is processed and then move with the tracking of various points in the hand with the algorithm developed. The next process is allocating various cursor controls to the various operations in the cursor to different hand gestures, like clicking is done by joining index finger and middle finger. The software's we utilise in this project are python. The output of the image is shown in the system screen to move with further process. Through this hand gestures we could able to perform various clicking and cursor moving operations without using physical mouse. Hence, the proposed work helps us to minimise the spreading of covid-19 by avoiding human interaction and the computer's reliance on hardware devices.
