Pure conjecture: relighting in Pixel phones. I don't think they have too many AR-like products. I'm surprised so much of this research is coming out of Google and not Meta.
I'm a little surprised Google hasn't included lidar into their Pixel phones (even after including and dropping some oddball stuff like Soli) to support some of these radiance field / photogrammetry techniques. I guess the <2.5% market share of Pixel phones wouldn't encourage any third parties with bothering to develop for lidar on Android.
