Abstract
A virtual keyboard which doesn’t require any external support and it can be operated by simply moving fingers on the paper on which keyboard is drawn, rather than typing on the physical keys of keyboard. In this paper, Camera is used to take input from the virtual Keyboard drawn on the paper. Here Camera is use to track the finger movements of typist to detect the users desired keystroke to type onto the Screen. Mapping of the keystroke is done to recognize the typed characters. The Proposed system is performed as: A Keyboard is drawn on a Plain Paper and user’s finger is been covered using colored tape. HSV (Hue, Saturation and Value) values are been set for the colored tape used by the user using the scale provided to set value on the GUI panel. The finger covered using tape can be discernible from background using BLOB Analysis. As well as a grid is provided on the panel in the GUI to display the finger moment of the user. Then the user start typing on the paper keyboard and the typed character is been captured using camera. Then based the position of the finger placed in the grid the character is been recognized and then the recognized character is typed on the screen.
