I am extremely skeptical about such things.
One reason for this is a job I had about 2 years ago at a motor show. Someone had had the bright idea that the presenter could stand at a Plexiglass lectern which was the monitor of a computer. The screen on the lectern was also projected onto a big screen behind the presenter so that the people could see what was going on. The lectern was only one layer of plexiglass and see through. The navigation was hand gestures across the screen on the lectern, and all it really did was play films about the product.
Great idea, super high tech image, super cool. They rehearsed with it for 3 days before they had the device sorted out so that it was half way reliable and the presenters knew which gestures would work and which wouldn't. My impression was that such things will probably work one day, but at the moment they are everything other than reliable and easy to use. And the question is, who needs it?
