It’s come to gentle that Lemnis Applied sciences, a startup creating varifocal optics to be used in VR headsets, has reportedly been absorbed by Fb in an ‘acqui-hiring’ transfer.
Lemnis co-founder and CEO Pierre-Yves Laffont launched a weblog publish in mid-August stating that the corporate can be “embarking on a brand new journey,” nevertheless at time it was unclear what that might imply for the Singapore-based startup.
As reported by Chinese language AR/VR publication Yivian, Laffont not too long ago up to date his LinkenIn profile to point that he’s been working full-time for Fb since February 2020, together with his most up-to-date posting at Fb Actuality Labs in Pittsburgh, Pennsylvania.Picture captured by Highway to VR
“Shifting ahead, we’re excited to proceed tackling phenomenal technical challenges constructing the subsequent computing platforms, with an excellent higher influence at an unprecedented scale,” Laffont mentioned within the weblog publish. “We hope you’ll find the subsequent chapter from the Lemnis Applied sciences workforce to be as fascinating and significant as we do!”
Of the corporate’s 9 staff, solely Laffont has up to date his LinkedIn profile to point the transfer to Fb. Others, together with the corporate’s VP of Operations Pierre-Yves Guillemet and Senior Mechanical Engineer Shukri Abdul Jalil, have since moved on from the corporate completely, which might point out that solely Lemnis’ IP and its core expertise (learn: Laffont) had been absorbed, however no different workers members.
Neither Fb nor Lemnis have publicly acknowledged an acquisition or particulars pertaining to 1. We’ve reached out to Laffont to offer additional clarification on the specifics.
Fixing a VR Drawback
Beginning in 2016 and later included in 2017 in Singapore, the corporate got down to remedy an issue that’s plagued VR since its inception: the vergence-accommodation battle.
If you happen to’re already effectively versed within the vergence-accommodation battle, hold studying. We’ve summarized what’s at stake with varifocal shows on the backside of the article.
Suffice it to say that future VR headsets will seemingly incorporate some type of varifocal expertise (and requisite eye-tracking) in effort to resolve this and due to this fact make VR extra reasonable and comfy for long-term use. Fb has been engaged on this difficulty since no less than 2018 when the corporate unveiled its personal varifocal prototype headset at Fb’s annual developer convention.Lemnis Applied sciences newest ‘Verifocal’ XR headset, Picture courtesy Lemnis Applied sciences
Lemnis Applied sciences first publicly demonstrated its ‘Verifocal’ prototype in 2018, which is predicated on an optic following an Alvarez lens design. This combines two adjustable lenses that shift in response to the attention’s gaze with a view to serve up a variety of focal planes. This differs from what we’ve seen from Fb’s varifocal prototype, which options adjustable shows to simulate depth of area. Each varifocal applied sciences use eye-tracking to perform this.
The corporate’s Verifocal platform, then formally unveiled at SIGGRAPH 2019, was meant to extra simply improve current industrial headsets with varifocal optics, eye-tracking, and combined reality-capable digital camera sensors. It’s clear the corporate’s specialization can be put to good use in Fb’s AR/VR skunkworks.
If you happen to missed that primer on the vergence-accomodation battle, hold studying under:

In brief, the vergence-accommodation battle is a bodily phenomenon that happens when the headset’s show presents gentle at a static distance out of your eye, making your eyes pressure to resolve no matter digital object you occur to be taking a look at.
In a headset with a fixed-focus show or optics, you’re mainly left with an uncomfortable mismatch that goes towards ingrained muscle reminiscence developed over the course of your total life; you see an object rendered a number of toes away, your eyes converge on the item, however your eye’s lenses by no means change form because the gentle is at all times coming from a static supply. You possibly can learn extra about vergence-accommodation battle and extra eye-tracking associated stuff in our intensive editorial on why eye-tracking is a sport changer for VR.
