Controlling 3D projected objects with your finger...
Anyway, I'm looking for an article about a form of controlling where it senses your nerves....
I've seen that in a documentary a couple of years ago. There was a girl playing a FPS just by holding her finger in a sensor. She controlled the game with her mind. It sounds really unbelievable, but I think it's true...
But I don't know how to find an article about that.
Here's a site with new technologies.
