Using Google VR Head Tracking without activating VRMode

Hi,

Out of all sensor fusion algorithms I've seen on the web, GVR's Head Tracking is by far the best and most precise sensor fusion algorithm on smartphone I could find.

It is so much better that I am trying to do something that might seem weird: I want to have access to

Code (CSharp):

1. VR.InputTracking.GetLocalRotation

without having either stereoscopic view, landscape mode forced or my view automatically rotating : I just need to access the quaternion.

I only managed to get GetLocalRotation to work if I first load the cardboard device

Code (CSharp):

1. VRSettings.LoadDeviceByName("cardboard");

But as soon as I do this:
- The whole scene rotates with my device
- Landscape mode is forced

Do I have to write my own plugin using Google Native SDK to achieve this?

Thanks!

 

Hey joejo, do you know if there are any plans to change this?

I'm trying to build a single app that handles Daydream, Cardboard, and Magic Window, but the current restrictions in GVR / Unity prevent this from being possible without UX issues (ex. daydream view interstitial popping up even when VRSettings.enabled = false). See this post of mine on GitHub:

https://github.com/googlevr/gvr-unity-sdk/issues/703

 

I use Google Cardboard SDK v0.6 to get a VR view without needing any native VR mode or additional Google VR services or apps installed on the device. I also have control over phone's orientation.

 

What's the version of your Unity Editor? Because I work with Unity 2017.1 and afraid that there is no way to use old GVR SDKs with newest Editors.
Thank!

 

You're correct, there's some problem with Unity 2017 due to a change on the constructor of com.unity3d.player.UnityPlayer. Here's more information on the problem (you can verify with your logcat you're getting same error): https://forum.unity3d.com/threads/crash-in-unity-2017-com-unity3d-player-unityplayer.492450/

For now, you can use Unity 5.6 with GoogleVR 0.6,
