Virtual Keyboard

The paper deals with the enhancement of human interaction with the digital world. Miniaturization of computing devices allows us to be in continuous touch with the digital world. Restriction of information on traditional platforms like paper, digital screen etc is overcome with the help of this technology. Dependency on traditional hardware input devices like keyboard, mouse etc will be reduced considerably, thereby allowing portability. It makes use of hand movements/gestures to feed input to a computer or any other digital device.The Virtual Keyboard is an adaptation of the 6th sense technology developed by Pranav Mistry,PhD student at MIT media labs.It works on a similar principle of hand movement/gesture control to perform simple functions like Right/Left click, Scroll control etc, which would otherwise have to be performed with the help of a mouse or a keyboard.Image Processing technique is an important basis for the implementation of this technology.The key features of this technology include media player volume control, power point slide control, camera control, scrolling,mouse control, initiation and termination of call.
