As traditional keyboard is bulky and inconvenient to carry , it fails to meet the demand of mobile terminal. In smart devices like Smart phones, tablets etc. a hardware keyboard is missing[1][2]. In order to overcome this the appearance of Virtual Keyboard presented is a new solution for input on portable device. This paper defines a new way of easy handling keyboard by using a smart phone and a paper keyboard (Fig.a) placed on a plane surface and also by using digital image processing . The virtual Keyboard will be done by using a smart phone with IP camera by using some suitable app, where the images will be captured by detecting the key pressed on the paper keyboard[3][4]. Through wifi there will be connection between Smart Phone and laptop/PC. Also the software used is the Matlab software. It will process and detect the character and display on screen and Virtual Keybord will have an additional feature of voice announcement in the background after every keypress.. Reference[5] also presented virtual keyboard using laser and image processing but the hardware is complex in it. As compared to this in this paper the hardware is less complex and it has more accuracy.
