Getting 6DOF with older 3DOF XR glasses

Video: How to get 6DOF with older 3DOF XR glasses using Breezy and OpenTrack

Breezy can now turn a 3DOF (degree of freedom) device into a 6DOF device by augmenting the missing positional data from a webcam. Spoiler! It is not the cam strapped to my face – this is just for the demo you can watch here, on PeerTube or YouTube.

The cam, that I used for this task, is sitting on my monitor. How this works? Well not with magic! This requires a somewhat decent webcam – really anything from the last decade should suffice – and OpenTrack, of course.

OpenTrack is a head-tracking application with multiple tracker plugins. One of it’s plugins is the Neuralnet Tracker, an AI powered extension that comes with a bunch of different head pose models to choose from. With a webcam connected this can now locally run the detection model with very low latency – so it’s usually blazing fast on most systems!

This alone is already 6DOF and is used a lot for gaming already – so what does Breezy do with this? Simple! It reads the forwarded data via an UDP listener, a very quick way to transmit data on a local network or system [and complements it’s own rotational data with the missing positional data].

With this a Breezy user still gets the rotational data from the XR’s very sensitive IMU, that is short for Inertial Measurement Unit btw, and the not so important positional data sent from OpenTrack.

This works of course only while the webcam can still see the user. So sadly no walking around while using this.

And the best thing? It can also send the data back! This means that the very same combined values can be forwarded – e.g. to a computer game – benefiting from the best available data sources for rotation and position.

That’s not the main use case, of course, and only of importance for some nerds like myself. This is mostly relevant for the productivity features of Breezy, because sometimes a text may be too small to read with the glasses on. We do no longer have to increase the font size – we can now simply lean in! That is a feature that is usually only available with glasses, that come with little cameras of their own, so they can have native 6DOF support. And when I say native I mean that such glasses usually also outsource exactly this calculation to the connected computer. It’s my understanding that this seems to require a lot of computation power, which is something many XR users with the more modern devices complain about.

Well not so much with OpenTrack and the Neuralnet tracker, that utilizes the ONNX runtime under the hood. That’s a high-performance, cross-platform engine to power exactly such models locally. The runtime automatically makes use of the best available hardware acceleration, if there is any.

Overall I’m rather hyped about this feature – especially because I’m using the OpenTrack output option of Breezy for quite some time now, to get a VR like experience with stereoscopic 3D rendering in Side-By-Side mode. I can now keep using my older XR glasses and still enjoy this more modern 6DOF feature. This is rather expensive hardware after all.

And all that on Linux PC!

Do you need an open source 3d joystick or "3d controller" ? Check out https://www.youtube.com/watch?v=YoGgdORVARs and https://gorkem.cc/projects/Trinteract/ #3d #spacemouse #cad #3dcad #3DOF

Btw., #HotelAstoria, the #VR app we and #hugfilms worked on at #blendFX a while ago, is available on #Steam.
All the #3d environment was modeled and rendered in #b3d, programming was done in #madewithunity.

Originally it was produced for the #OculusGo, but shortly before we finished it #Meta killed off the whole #3dof platform, so we didn't have a way to publish the app, resulting in a lot of extra work to make it work on other platforms.

Made progress on the 3DoF simulator today. The traction loss motor is mounted with the control arms roughly measured out. Just need to fab up a frame mount and weld it to the bottom frame and then I can paint it. Next up fabricating the seat frame #simracing #3dof
