Project Standalone

UW Reality Labs' in-house standalone XR headset. Compute is a Qualcomm RB5. Display and optics come from Project North Star, in a modified form factor. The software stack is a Godot launcher running on a Monado fork with custom drivers, on an Arch-based OS.

Software components

Layer	Scope
App	Launcher in Godot via OpenXR. Starts other OpenXR apps and composites non-XR apps as in-app windows. Repo: https://github.com/uwrealitylabs/standalone-launcher
CV	SLAM: hardware-accelerated (e.g. GPU) implementation, not Basalt out of the box. Hand tracking: required; open whether to build from scratch as a learning exercise or integrate (e.g. Monado's Mercury)
Runtime	Monado fork with drivers for our hardware → Monado headset driver
OS	Arch-based; see OS and kernel
Drivers	Displays, cameras, IMU. Panel driver ported from the RPi 5 build → Display

Ownership

Hardware lead: everything below the kernel (FPGA firmware, camera sync, hardware timestamping).
Software team: kernel drivers and up.

Launcher dependency

Launching other OpenXR apps and compositing alongside them depends on Monado's multi-client service mode and overlay support. Confirm these cover the launcher's needs before building on them.
