Abstract

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.

Apparatus for improved virtual keyboard input

    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.

These would be oriented under the F and J keys. The pieces can either be separate (2 pieces) or connected. This is illustrated in figure 1. An apparatus such as above with a location transmission mechanism. The apparatus transmits

its location to the projection device which then automatically "aims" at the apparatus. The apparatuses above with a ground-fastening mechanism such as rubber strips on the bottom
