In recent years, the popularity for natural interfaces has experienced tremendous growth. Natural interfaces provide the computers or the so called machines with a sense of humanity. The basic knowledge required to understand and utilize a computer system is reduced to a minimal extent. There have been recent commercial developments in the area of natural interfaces, including the Microsoft XBOX Kinect and Nintendo WII. However, the capital cost of such a system remains very high. The primary intention of this paper is to design a technique to redesign every aspect of our interaction with the computer. It explores and develops an interface that helps simple computer systems to support gestural interface. We could utilize the low cost cameras available with the laptop or desktop to support detection of human gestures and multiple touch experiences, which would ultimately lead to the direct interaction of computers with humans. In such a system, the need for external input devices like mouse and keyboard could be eliminated. The paper discusses how such a system can be implemented, along with a brief description of the approach used.
