VIRTUAL KEYBOARD: AN INTELLIGENT INTERACTION SYSTEM FOR DESKTOP USING STANDARD CAMERA

A virtual keyboard is a type of keyboard which doesn’t require any external physical support and can be operated by simply moving fingers, rather than typing on the physical keys of keyboard. Camera tracks the finger movements of typist to get the correct keystroke. The software and hard ware type recognizes the typed characters and passes to the computer. The Proposed system is performed as: the typing will be captured by camera and the object can be discernible from background using BLOB Analysis. Then we estimate the location of user’s fingertip by fingertip detection. By using Shadow analysis, we check whether the fingertip is in contact with the table keyboard mat. Mapping the touch to keystrokes and recognize the character and finally, sending the keystroke to the display screen.
