This AR headset bakes eye-tracking right into its OLED displays
Fraunhofer FEP has cooked up a new headset building on its latest bidirectional OLED microdisplays which, in addition to OLED pixels, have photodiodes sandwiched in-between. With those, the tiny screens can not only show data to the wearer, but watch where that person is looking too.
The bidirectional micro displays each run at 800 x 600 resolution, in fact, though Fraunhofer says that it’s really a starting point for commercial brainstorming.
However, potentially more important is foveated rendering. That effectively prioritizing graphics potency for the areas that the wearer is looking at directly, whereas the periphery is allowed to run at a less system-intensive resolution.
