Hand gesture based TV

Abstract

This project aims to control the TV through hand gesture without remote control, two important problems are taken into consideration while determining the gestures, first one is , choosing simple , expressive, and limited number of gestures to make it easy to be memorized . the second one is recognizing these gestures. A solution to these problems is that , users have six gestures to handle television control , the open hand for switch on the TV , the closed hand to switch off the TV, the other two gestures are for increment and decrement operations ( for both volume and channel) the fifth on to switch from the channel mode to volume mode , and the sixth gesture for no operation mode. While the other issue which is how the computer can recognize the gesture its solved using artificial neural network. We made a prototype of this system using a computer , webcam, interfacing circuit, parallel port and television, knowing that a black background was adopted . the system was implemented and tested successfully with an accuracy of 95 %.
