Are there computers controlled from the air like in the movies?

Question

Computers

Dear experts, does anyone know if there are now computers with air control like in films?
Some kind of image is projected in the air and this image can be controlled...
A vivid example of such a computer is used in the film "Iron Man".
Still, such a computer, such technologies, is it something real or is it a movie feature so far?

Thank you.
