Over a decade ago I used a holographic video conferencing system that used kinect for depth mapping, it was very convincing. It would also reorient the display based on your head position. so you could look "around" the avatar. There are demos of binocular 3d conferencing done with a lenticular display (lookingglass), although those large displays are extortionately priced (1/4 of the size of this google one is $3000...) - keeping them out of the hands of most devs. No doubt google are doing the same, but can afford these larger displays. You can easily find examples (and research papers) by googling for the relevant terms. Google claiming they have invented a "new technology" just shits on all those folk who dont have the publicity/funding of google.
