My problem with the video is that it's the kind of depiction you get when there is nobody able or willing to say "this is impossible to do". Every display seems capable to project 3D images in the air, some of them translucent, others opaque. At the same time, there are screens hung on walls (or on fridge doors). There is also a translucent touchscreen that seems to project different images on each side. Technically,…
3D projection in the air is already being done: http://www.aist.go.jp/aist_e/latest_research/2006/20060210/2...
As for the translucent screen, projecting different images on each side is (at the same time) is just an assumption. It could very easily have a accelerometer to detect the 'flip' and change based on that.
