Hello everyone

Update to my previous post: https://www.reddit.com/r/Xreal/s/aacV6fUqxI

Here is a short demo of Half-Life: Alyx running through XR Gate on XREAL Ultra AR glasses, running on the AMD Radeon 890M iGPU in a Ryzen AI 9 HX 370 mini PC.

No external trackers are used. Tracking (6DoF + hand tracking) comes from the glasses cameras. For input/buttons, I use inexpensive Bluetooth VR controllers that are mapped to/emulate SteamVR left and right controllers.

You can try it on Linux:

Hi everyone,

I want to share my open-source project XR Gate:

https://github.com/vladoshub/xr-gate

XR Gate is an experimental XR pipeline that allows dual-camera AR glasses to be used as a lightweight VR/XR headset with basic 6DoF tracking, hand tracking, and controller emulation — without requiring proprietary vendor SDKs.

At the moment, the main supported device is XREAL Ultra.

Current features:

* 6DoF / 3DoF tracking modes

* ML-based hand tracking with gestures such as grab and pinch

* External controller input — use gamepads or joysticks for button input while hand tracking provides the spatial pose for the left/right virtual VR controllers. Supports per-controller remapping

* Fallback controller input mode — read button input from external controllers when hand tracking is lost or unstable

* Experimental spatial vision support, used in the demo project

* Experimental 90 Hz mode, with some limitations

* Ubuntu 24.04 support; other Linux distributions may work, but Ubuntu 24.04 is the only tested target

* Open source

* No proprietary vendor SDK dependency

* Seamless switching between 6DoF and 3DoF, useful for seated or lying-down use

* Experimental tap-based controls for switching modes

* Working SteamVR and Monado drivers are included

Important disclaimer: this does not turn AR glasses into a full replacement for a real VR headset. The FOV, tracking precision, stability, and overall experience are still much worse than a dedicated VR headset. This is more of an experimental portable XR/VR setup, especially useful for developers, tinkerers, and people who enjoy XR experiments.

There is currently no Windows support.

Some default settings may also not work perfectly for everyone, especially gesture behavior. You may need to get used to it or tune the startup/runtime parameters for your own setup.

Where I think this can be useful:

* As a very lightweight portable VR/XR setup for travel

* For VR/XR developers who want to quickly test an application without carrying a full headset

* As an experimental companion for handheld PCs

* For developers interested in computer vision, tracking, and XR pipelines

* For games or applications where you can combine modes, for example using 6DoF/3DoF tracking while disabling hand tracking and using standard controls instead
