Tangible Hologram

Although they quietly insist that those holograms are tangible 3D hologram but I still think this is merely a humble 2D projection with fairly limited interactive features on thin air at this stage. I believe hologram is on the way of moving away from two-dimensional and have now entered the limitless virtual world. I would dare to hope that when we touch a check box, floating in air, then a tick could appear on it in the near future.
