I work on glasses-free 3D: the optics, the open software that drives it, and the 3D content and AI it needs.

A multi-directional backlight: each pixel sends light in several directions, so each eye sees its own image. Drawn with the DisplayXR web SDK, in 3D on a DisplayXR display and flat everywhere else. Drag to tilt it.


DisplayXRAn open runtime for 3D displays

Spatial displays now ship from many vendors, but each app still has to integrate each panel by hand. DisplayXR is a vendor-neutral, OpenXR-based runtime: write an app once and it runs in 3D on any supported display, on Windows, macOS and Android. Leia is a founding member and the first display vendor. The project is independent and open to every display maker.

LeiaGlasses-free 3D, from the lab to products

Leia grew out of my research at HP Labs on diffractive light-field backlights, published in Nature:

Fattal et al., A multi-directional backlight for a wide-angle, glasses-free three-dimensional display. Nature 495, 348–351 (2013).

Today Leia builds switchable 3D displays with eye tracking and AI-based 2D-to-3D conversion for phones, tablets, laptops and monitors. More at leiainc.com.

Leo (@leofattal) and I build games together for fun. He is also a DisplayXR contributor: he wrote the Minecraft Bedrock stereo mod for DisplayXR Play and some runtime fixes.
