Meta Quest Pro’s eye tracking might do more than previously thought.

Text explaining the eye-tracking features was discovered in the Meta Quest 2 beta firmware. VR leaker Brad Lynch posted the description on Twitter.

“Eye tracking is a feature of your Meta Quest Pro headset (also known as Meta Quest Pro device) that uses cameras to estimate the direction your eyes are looking. This feature is used to make eye contact and facial expressions of your avatar more natural when interacting virtually with other users and to improve image quality in the area you are viewing in VR,” it reads.

It further states that eye tracking can also be used as an input method to interact with virtual content. According to the description, eye tracking will not be used to identify users. It will be possible to enable and disable eye tracking in the settings of individual VR applications or in aggregate.

Foveal rendering: a powerful rendering technique

While the other features of eye tracking (eye contact, input method) are confirmed or obvious, the image enhancement mentioned in the text makes us sit up and take notice.

Could this mean that Quest Pro will support rendered foveal? This rendering technique uses eye tracking to determine which area of ​​the image the eye is currently focusing on, and only that area is rendered in full detail. This saves a lot of computing power, which developers could invest in higher resolution or better graphics.

The Playstation VR 2’s gaze tracking also supports foveal rendering, and according to early press reports, it does so with one big advantage: the image is exceptionally sharp without reduced graphics being noticeable in the periphery. visualization. In a GDC presentation, it was said that the Playstation 5 can render 3D graphics up to 3.6 times faster with foveal rendering enabled – a huge performance boost.

It’s not yet clear how accurately foveal rendering works in Sony’s VR headset. This will be clarified in more extensive testing in the spring when PSVR 2 is finally released.

Does Meta Quest Pro support foveal rendering?

Meta’s description does not necessarily suggest foveal rendering for Meta Quest Pro, especially since Meta’s chief technology officer, Andrew Bosworth, said nearly a year ago that rendering technology “doesn’t not yet bring that much in terms of performance” for stand-alone headsets.

However, the headset could also benefit from eye tracking in other ways: for example, by displaying the targeted areas in certain VR applications with higher resolution or by applying algorithms against image distortions. Both could lead to better image quality.

In any case, the description gives hope that Meta Quest Pro still has one or two surprises in store, despite numerous leaks. The helmet will be unveiled on October 11 and will go on sale the same month.
