Polling Oculus raw sensor data with native support.

Unity Engine
1

I’d like to upgrade to 5.1 and to use the new native support for Oculus. However, my use case requires raw accelerometer data. It doesn’t look like this is exposed anywhere from what I can tell. I see there is some sort of native pointer:

http://docs.unity3d.com/ScriptReference/VR.VRDevice.GetNativePtr.html

However, there is no documentation on how to actually cast the IntPtr to an Oculus data structure / function and use it. Any guidance you could give here would be appreciated. I pretty much can’t take advantage of the native optimizations until I figure out how to get the sensor data. I’m sure there are probably other developers in the same situation.

Thanks,
Ben

Bump. I’d take an answer of “not possible right now” with an ETA, but I’d at least like an answer. Thanks!

Oculus is planning on releasing a set of utilities that exposes the data that Unity 5.1 currently does not. This is happening in the next 2 weeks, but I don’t know the exact date.

And thanks for bringing up the missing pieces that are important to you, it’s useful for our future planning of Unity VR.

Hi. This topic is important for my bachelor thesis. Are there any news?

Oculus released their set of utilities earlier this week here: https://developer.oculus.com/downloads/game-engines/0.1.0-beta/Oculus_Utilities_for_Unity/

Please give this a try and see if it meets your needs.

We are still planning on hooking up Oculus sensors to Input.Gyro, but I don’t have a timeline on it.

Thanks for the link, getting it now. Urg it’s scary using something titled 0.1.0-beta

Hmm… I don’t see anything in that link for actually downloading utilities from Oculus? It looks like it just recommends using patch p3?

I have had similar desire – to use angle of head to apply some force (steering)… I tried VR.InputTracking, but unsuccessfully. For right now, I am trying a workaround based on the eulerAngles of the camera (since it rotates along with head, and is 90 Z at full-left-tilt and 270 at full-right), but that wouldn’t work for all cases…

Weird, all I see is a place to download the utilities :smile:2199063--145998--Screen Shot 2015-07-10 at 7.36.03 PM.png

Weird, now that’s all I see… bizarre, not where the link took me earlier?

EDIT: Doh! It skipped the actual link at top and jumped to Release Notes. Okay, it was the right page. I’ll hold onto this in case I need it (which I probably will, since getting sensor info seems to be lacking from Unity’s native support)
