Lynx launched an open-source 6DoF positional monitoring system that ought to work on any Android headset with a Qualcomm chip.
For those who’re unaware, Lynx is a French startup that in 2020 introduced Lynx R1, a standalone combined actuality headset with an open periphery design. Had it shipped on time, in 2022, it could have been the primary client standalone headset with shade passthrough. However after repeated delays it was crushed to market by Meta Quest Professional, and by the point most backers had acquired their headset, Quest 3 and Apple Imaginative and prescient Professional had shipped too.
One among Lynx’s core acknowledged ideas is to be as open as potential, together with open sourcing no matter it could actually. Now, the corporate has launched a ready-made 6DoF positional monitoring system for Android. It ought to already work for any headset utilizing a Qualcomm chipset, and may be modified to work on any ARM {hardware}.

To be clear, the Lynx R1 by default doesn’t use this open-source answer. Qualcomm, the corporate behind the chipsets that energy each non-Apple standalone VR headset available on the market, additionally supplies a closed-source positional monitoring system if corporations need. Whereas greater corporations like Meta and Pico roll their very own monitoring system, smaller corporations like Lynx typically simply use Qualcomm’s offered software program.
For Lynx, the exception to this can be a small variety of prospects who work in environments the place the software program analyzing digicam imagery must be open supply.
“Open-source SLAM algorithms are excellent, and have been good for the final 8 years or so. There’s a good selection to select an algorithm with a very good vary of sensor configurations. The actual drawback with 6DoF has been the productization of it: together with it within the runtime, managing edge-cases, restoration, and so forth.”
– Lynx founder Stan Larroque
For these prospects, and in pursuit of its ideas of openness, Lynx tailored the industry-standard ORB-SLAM3 algorithm to run properly on Android and leverage the {hardware} acceleration of the Hexagon DSP on Qualcomm chipsets.
DSPs are specialised chips designed particularly for sensor and picture processing. Leveraging the DSP offloads a lot of the computational work away from the CPU, drastically decreasing the efficiency price of positional monitoring. This method is used on all delivery standalone XR headsets.
Oculus Quest ‘Considerably Sooner’ Than Oculus Go, 6DoF Monitoring ‘Doesn’t Have an effect on’ Efficiency
Oculus Director of Ecosystem Chris Pruett revealed in a discussion board AMA yesterday that Oculus Quest shall be “considerably sooner” than Oculus Go: Quest is considerably sooner than Oculus Go from each a CPU and GPU perspective. A part of that is simply the uncooked efficiency of the chipset itself, however a
Lynx says the result’s an open-source library that takes in 640×400 digicam inputs and outputs a 6DoF pose at 90FPS on a Snapdragon XR2 Gen 1, the Qualcomm chipset in Quest 2, Pico 4, and Lynx R1.
You’ll find the documentation for Lynx’s adaptation of ORB-SLAM3 for Android XR headsets on its web site.
It is accessible underneath the GPLv3 license, which means anybody that ships it should maintain it open supply underneath the identical license.
