Google Glass of the future

An American patent of October 2011 reveals that in the future Google Glass could look like completely normal glasses. The technology now used by Mountain View to carry the image of the applications is that of a project that does not contemplate the use of the glasses of the glasses. In fact, it really only takes the idea of ??the classic glasses frame to place a projector directly to the retina.

The key to current glasses is a prism. At the end of the mount is a projector that emits an image on a prism. Through this, the natural light passes collecting that projected image that reaches us directly to the retina. Since each eye and each face is different, its angle can be adjusted for correct vision.

In this other patent a little later than the original Google Glass but that has been approved yesterday by the USPTO, we see a different way to approach it. A real screen exists in the glass itself. In the patent it is described as screen close to the eye with diffraction grating that tilts and focuses the light. That is, this would allow the prism to disappear and be installed directly on the glass.

The subsequent description that they make of the nature of the screen is somewhat confusing but it comes to say that it is composed of a substrate that lets light through. It contains a grid with a continuous diffraction pattern. Diffraction is the reflection of light with an opaque body. Intentional manipulation of the elements that make up that diffraction grating would generate the type of image to be transmitted. That is, with natural light itself would also create artificial images.

<p>It is only a patent and may never be realized, but on occasion Sergey Brin has talked about adapting Glass to normal glasses. This patent shows that they know how to do it.</p>
