A virtual keyboard had recently been disclosed in the popular press. As shown below, a projection device connected to a computing apparatus projects an image of a keyboard. The device also has the ability to detect when a finger taps a virtual key. One problem with such a keyboard is the lack of feedback, especially for touch typists. We propose an apparatus that, used in conjunction with a virtual keyboard, will provide some feedback. We consider the following variants within the scope of the invention: A small, preferably plastic, preferably thin and flat, piece with raised areas to assist touch typers.
