Meta’s Quest SDKs now allow putting digital objects on surfaces with out a scene scan, displaying a passthrough cutout of any keyboard, and discovering close by headsets for colocation by way of Bluetooth.
On the spot Placement and Keyboard Monitoring can be found in v71 of Meta’s Blended Actuality Utility Equipment (MRUK), and Colocation Discovery is out there in v71 of the Meta XR Core SDK.
On the spot Placement
Many combined actuality apps place digital objects on actual surfaces, equivalent to your desk or wall, by leveraging the Scene Mesh that Quest 3 and Quest 3S can generate by way of the elective combined actuality room setup course of.
If an app tries to leverage the Scene Mesh in a room the person hasn’t scanned one in, the person will likely be pressured to undergo that setup course of, which might take as much as a minute of panning their head across the room.
That is a number of friction for an app that will solely must know the place a desk or wall is and that is what MRUK’s new On the spot Placement function goals to resolve.

As an alternative of utilizing the Scene Mesh, On the spot Placement leverages the Depth API to supply a raycast from a controller or hand to an occluded place in 3D house, permitting spawning a digital object or interface on a floor.
Bear in mind, nevertheless, that that is solely applicable for spawning easy stationary objects and interfaces. If they should transfer across the desk or work together with any of the remainder of the room, the Scene Mesh would nonetheless be wanted.
Keyboard Cutout
Meta’s SDKs have included a function that permits rendering a digital model of choose supported tracked keyboards for years now.
However trying to mannequin each potential Bluetooth keyboard could be a dropping battle, and in v71 of Quest’s Horizon OS Meta added the flexibility to trace any keyboard and minimize it out by way of passthrough, as a substitute of rendering a mannequin of it.

Now, that functionality is out there to app builders too, as a part of MRUK. Meaning any VR app that wishes to can have your keyboard present by way of a passthrough cutout, notably helpful for productiveness software program.
Digital Desktop has been doing this manually for months now by leveraging the monitoring of the choose supported keyboards. Now, in principle, its developer might broaden this assist to any keyboard.
Bluetooth Colocation Discovery
For over a yr now, Quest headsets have supported same-space native multiplayer, often called colocation, by way of the Shared Spatial Anchors API.
However a significant friction level in enabling colocated experiences has been the necessity to use the identical sort of UX as on-line multiplayer, a contact invite or room code circulate, typically involving a sequence of menus.
Quest 2 Lastly Helps Shared-House Native Multiplayer
Quest 2 lastly helps shared-space colocation. “Colocation” is the time period for a number of headsets sharing the identical bodily play house with the identical digital coordinate house. Fb confirmed off an “enviornment scale” prototype of this function in late 2018, however didn’t ship it to a headset till late final yr
With v71 of the Meta XR Core SDK, Meta now has a Colocation Discovery API. Below the hood, it leverages the headset’s Bluetooth connectivity to permit it to ship a small quantity of information, 1024 bytes, to close by headsets to speak the wanted parameters to affix a session.
In principle, this implies builders ought to be capable of construct a simplified native multiplayer UX the place one headset hosts a session and close by headsets robotically be part of it.
