A STUDY ON CONTROLLING A COMPUTER WITH HAND GESTURE

Hand gesture is an innovative technique of interaction between human and computer. As compared to existing techniques, hand gesture technique has the advantage of being easy to use. By using this technique the traditional way of using mouse and keyboard will be change because one can then interact with the computer with hand gestures. In this technique, ultrasonic sensor is used to classify the hand movement in real-time. Ultrasonic sensor measures the distance of hand by using sound waves. The main idea of our approach is to speed up the interaction with computer, using general purpose hardware like personal computer, Arduino UNO board and low cost sensor like ultrasonic sensor. In this way any user can easily interact with the computer using hand gestures.
