System Input Using Marker Based Hand Gesture Recognition

Abstract

Human Computer Interaction(HCI) has been changed in this new era. People want to interact with their devices in such way that has physical signi cance in the real world and of course want ergonomic input devices. We propose a new method of interaction for the computing devices, having a consumer grade web-cam, with the beck of the hand. Our system is also suitable where touch screen is not feasible like large screen or projected screen. Our method uses two colored marker(red and green) worn on tip of nger to generate eight distinct hand gestures. We have implemented all the usual system commands through di erent gestures. Our system can easily recognize these gesture and give corresponding system commands.
