It’s a design done in collaboration between the Optics Team and the Firmware team, and utilizes the core nanostructure of the Lume Pad’s DLB backlight in tandem with low-level Android OS wizardry.
It’s super complicated! Even I can’t totally wrap my head around it!
I assume the wallpaper needs to be special so it can use DLB to project in to the background. Android needs to continue to use the ‘normal’ 2D screen at the same time DLB is running. Like rubbing my tummy and patting my head at the same time. The special wallpaper allows Android app icons and widgets to be displayed without interfering with DLB.
Imagine the possibilities! Exploiting lightfield at the same time as maintaining compatibility with everything else. Outstanding!
@Kano3D In theory, yes. In practice, there are only very particular things that this specific implementation would be useful for. We’re always trying to do new and cool things though!
