Laser projection keyboard already exists
The less your computer, the easier to use. And most important it takes up little space. A clear proof of the decrease in the size of different gadgets. However, "sharp" is still a problem with the keyboard, in that moment, when you are using a desktop computer. That is why, scientists have created a prototype laser projection keyboard.
The principle of operation of this device has long been known. A device using a laser beam projects a glowing button on any flat surface. It is at least convenient, and from the point of view of fashion and unusual. And of course the key point is space-saving. The lack of a large push-button "Board", replaced by a small laser projector saves space, provides additional ergonomics of the workplace.
For design laser keyboard can be connected not only to ordinary computer but with a smartphone or tablet. Thus to expand the range of possibilities of this gadget.
