LOL, That is incorrect. There was also a hologram of Wil.I.Am and the person in the studio looks at the hologram and describes how Wil.I.Am appears to him
"IN THE STUDIO".

This all reminded me of project bluebeam and it impressed me because anyone
that understands the properties of light would know that it needs to reflect off a surface. In the video there is no smoke or screens. The hologram is in mid-air AND is 3 dimensional!
Also, MSNBC also used this technology for virtual reality holographic displays and they actually interact with the hologram. I'll leave that one for you to research though.
To cut a long story short.. Yes, it is an actual 3-d hologram; NOT an image super imposed unto the screen.
