The New York Times reports that Google is working to deliver a heads-up display allowing users access to email, maps and other tools through a wearable interface. You could do all this while at the library, reading census records, or even while playing online games.
The device reportedly will be available later this year, and sell somewhere in the raange of $250 to $600.
The glasses will be worn like normal eyeglasses. A small display screen will sit a few inches from the eye. The glasses will also have a 3G or 4G data connection and a number of sensors including motion and GPS as well as a low-resolution built-in camera that will be able to monitor the world in real time and overlay information about locations, surrounding buildings and friends who might be nearby. The glasses are not designed to be worn constantly, but will be more like smartphones that are used when needed.

I suspect this will become part of the next generation of ever-shrinking computers. Laptop computers, or whatever we wish to call them, can already be built smaller than existing units. The primary obstacles today are the size of the keyboards and the size of the display screens. Making them smaller with existing technology results in units to small too be used. It sounds like Google may have found a solution to one of those obstacles. Now, how do we shrink the keyboard?
