As cool as this is, it's not really a hologram. This is an example of Pepper's Ghost, which is also what's used to project images into your field of vision using Google Glass.
This is one of the coolest things I have seen. I hope that this is the direction that user interfaces goes in down the road, it is much more exciting than 2D.
this is amazing. the future of the interface indeed. forget iron man this is more like star wars. but more seriously, i'm very interested to see what comes next with this in terms of interaction. i'm not sure how long lived the LEAP device will be, but this sort of holographic interaction technology certainly has a big future!
The following is a fake video of a hologram gaming console. I hope it will inspire someone to make it real: <a href="http://www.youtube.com/watch?v=iaaHcH9nQmI" rel="nofollow">http://www.youtube.com/watch?v=iaaHcH9nQmI</a>
