Google already has been researching lightfield technlogy:
https://www.blog.google/products/google-vr/experimenting-light-fields/So this is probably adding the stuff that Lytro did to that,since they want to leverage this for VR use.
OTH,it also has implications for phone cameras a few years down the line. Being able to selectively blur and bring into focus objects after the picture is taken,would be another step in computational photography for the masses. The only issue is the hardware is quite bulky,but I can see as it is refined it might be possible in a smaller form factor at some point.
