Hologram Keyboard Technology

I saw a Holographic keyboard in the invention fair. There was a small stick like thing that would display an image of a keyboard like a projector would; When a spot was touched that had the light of that key on it the computer would then type that key just like a normal keyboard. At first when the key was touched I thought that the blocked light was sending a signal but other keys were blocked but only the key that was touched was input into the word proccesser.

The stick could be placed a lot of diffrent way and could be focused, to make the keys bigger or smaller. Only when the surface of the object that the keyboard was projected on, was the key typed then inputted into the computer.

It cought my eye and made me wonder how it worked so well and what went into designing that piece of equipment.
