Broadly speaking: yes! I wish we used this more, it's not hard and it looks very convincing and subtle stuff feels quite good... ... when latencies are VR-like. When it lags even a little, it feels awful. So it tends to work pretty well for tech demos like this, and not at all when exposed to the real world. Specialized hardware and software stacks can do a pretty good job - see the Fire Phone for an example there. It did quite well on technical notes, the experience was smooth and battery-efficient(-enough) and the illusion was almost fast enough to be transparent. But it failed. Unless we get this kind of thing baked into everything for years, it will continue to fail, because there will be no content. And integrated webcams and their related software continue to be utter shit. We're not close to (or even moving towards) being able to use this, unless Apple surprises everyone in their next lineup and kicks off a renaissance. ..... and that's before getting into privacy issues with exposing an API that reveals info about your face. It's a harder practical realm than it seems it should be, when people have been making very effective tech demos for decades on commodity (but specific) hardware.
