we get in huge steps off-topic here
@Ben
No, Minority Report-like interfaces are for small men like Mr Cruise, who like huge, room spanning gestures...
What I have in mind is a 3D mouse, like in my sketch here:
The ball has to hover somehow, to allow rotations like a conventional trackball, but push/tilt/lift also for the 3 room axis; with such a device you could manipulate 3D objects on a screen (or VR) very intuitive.
@Pielle
hmmmm, very charming (you're Italian?

) but the men in my family die before 60 - I don't expect that happening in the next two years, or, die in their mid 90ies - which in my case asks for some revolutionairy therapy for Parkinson, I suffer for quiet a while (I'm excellent in testing Optical Image Stabilizations LOL

)
Naw, mind control? I would prefer some sort of 'real', tactile, force-feedback …
And, Ben, I'm a huge fan of my MTP too - I said in some other thread, I think, FCPX is made for such an input device - alone 'swiping' thru the timeline is awesome!
