Design and Implementation of Gesture Recognition and Writing Text Virtually Using Finger

Abstract

This paper deals with real time gesture recognition and writing alphanumeric letters over the air using fingertip. The human and machine interaction lays an important role in gesture recognition. The proposed method contains two parts: First, a video camera is used to acquire the image for gesture recognition and then the fingertip is recognized from the live video frames. In this work, the Optical Character Recognition (OCR) algorithm is applied to plot the alphanumeric characters with respect to the finger movement. As a result, we can eliminate the requirements of the input devices like keypad, mouse, stylus, stick, and glove or pen and so on. Using Python language coding, we have obtained the text on the screen. Further, recognition of gesture does not require sensors or any hardware other than a camera. Since, the proposed work is a simulation based approach; hence the developed algorithm executes the recognition task in a simple, fast and lucid manner.
