[VIVE OpenXR support for VIVE Cosmos]

We are using the Vive Pro Eye with Unity and OpenXR. When we use the SteamVR OpenXR runtime EyeGaze Interaction does not seem to be supported. Is there a different runtime or a different setup we should be using?

Still nothing on this?

[OpenXR faillure with SRanipal]

Is there indeed OpenXR gaze support available in Unity for the Vive Eye Pro?

I am using Unity 2021.1.15, SDK and the Unity OpenXR plugin v1.2.3.

I set up the control scheme like so:

 

 

 

 

The Gaze Ray Sample works in this scene, but I seem to be missing the connection to the New Input System and/or OpenXR.

Thanks @Hank_Li for your suggestion, but I have no trouble using physics raycasts. 

I believe I confused the issue by mentioning the nose tracking.  The problem is that the eye tracking system doesn't  appear to work on machines WITH OR WITHOUT a Vive Pro Eye when the build was performed on a machine that hasn't had a Vive Pro Eye connected to it.

What I am looking for is whatever files or libraries are missing from the development machine that enables the build to work properly.

I am just about to revisit this issue on another project and I will start by only installing the SRAnipal libraries to isolate that from the Tobii libraries.

I'll discuss with @Jad off-line and post back if we find a resolution.

I am wanting to us the SRanipal functions on systems with and without eye tracking capability (on the Vive-without-Eye systems it falls back to nose tracking).

The issue is that I am the only one on the team that can make a build that works (I assume) because I am the only one with a Vive Pro Eye.  This is not optimal on a team with 6 developers who want to be able to build our app.

If @Daniel_Y, @Corvus, or @Jad have any suggestions I would love to hear them. @Hank_Li

Yes, it does-- if it is built on a machine with a Vive Pro Eye. 

Eye tracking does not work at all when the build was performed on a machine with no HMD and then run on one with a Vive Pro Eye.

We have a medium sized team building an Vive Pro Eye-enabled app.  The people doing the final builds are not necessarily the ones who have access to the Vive Pro Eye (especially since we are all working under shelter-in-place).  We are having trouble getting the builds to work with eye tracking when built with systems without HMDs.  We have installed the SRAnipal runtime on those systems and yet the builds still aren't working.  Is there an obvious set of files or data that we can transplant to make this work?
