The most recent Meta MR Utility Equipment SDK replace for Quest 3 lets Unity builders simply decode and 6DoF observe QR codes.
It is already potential for builders to decode and/or observe QR codes utilizing a third-party or customized pc imaginative and prescient library, as Meta has given Quest 3 builders entry to the headset’s passthrough cameras, if the person approves, since early this 12 months.
The brand new Meta MR Utility Equipment for Unity replace delivers this as a system-level function. It is a lot faster and simpler to implement, and solely requires the person to grant the Spatial Information permission already used for different combined actuality options, not the extra nefarious Headset Digicam permission.
When QR code monitoring is enabled, the SDK gives a 6DoF positional pose, 2D bounding field, 2D boundary polygon, and decoded payload of the code, akin to a URL.
QR Codes are the second “trackable” of Meta’s MR Utility Equipment, becoming a member of the prevailing Keyboard trackable. For those who depend Contact controllers and the Logitech MX Ink stylus, it is technically the fourth type of inanimate object that Quest 3 can positionally observe at a system-level.
Meta notes that, as with keyboard monitoring, the place replace fee is comparatively low, so this is not appropriate for monitoring shifting objects by strapping QR codes to them. The place will replace if the QR code is moved, sure, however not in real-time. This is not like getting a Pico Tracker for the price of printing a QR code on a bit of paper – it is extra akin to visionOS 2 object monitoring.
Additional, even this low-rate monitoring has a efficiency value, so Meta recommends enabling the function dynamically when wanted.

Builders might use tracked QR codes as a extra dependable methodology of preliminary calibration for colocation, in comparison with Meta’s Shared Spatial Anchors system, which does not at all times work effectively.
Whereas it is most likely not a good suggestion to depend on client audiences having a printer in 2025, it might be significantly helpful for enterprise and location-based VR and combined actuality growth.
QR code monitoring is an non-obligatory function in v78 of Meta MR Utility Equipment for Unity. It helps Quest 3 and Quest 3S, in addition to all future Horizon OS headsets, and helps QR codes as much as model 10.
