Hi, I'm testing using OpenXR and the new Vive WAVE. I'm able to run the demo as described here and the tracking works as it should: https://developer.vive.com/resources/openxr/openxr-pcvr/tutorials/unity/integrate-facial-tracking-your-avatar/ . However when using the OpenXR Unity Gaze system, the device is not tracked. The following code prints 'Not tracked', meaning an EyeTracking device has been found, but is not tracking. private InputDevice eyeDevice; private static readonly List<InputDevice> Devices = new(); private void Update() { if (!eyeDevice.isValid) { InputDevices.GetDevicesWithCharacteristics(InputDeviceCharacteristics.EyeTracking, Devices); if (Devices.Count > 0) { eyeDevice = Devices[0]; } Debug.LogWarning("Not valid"); } else if (!eyeDevice.TryGetFeatureValue(CommonUsages.isTracked, out bool isTracked)) { Debug.LogWarning("Failed to access isTracked"); } else if (!isTracked) { Debug.LogWarning("Not tracked"); } } Vive Pro Eye Unity 2021.3.1f1 SRanipal 1.3.5.4 VIVE Wave OpenXR Plugin 1.0.4 Both Facial tracking and Eye Gaze Profile are on:

Thanks for the reply either way. Raycast is not an option for us but I still don't know how it would help since I'd need to do the inverse projection matrix calculation and I don't know the projection matrix for the VR view. It seems that this whole issue is actually a Unity bug / behaviour so I'm trying to solve it with them now, see http://fogbugz.unity3d.com/default.asp?1304082_gsk09e85lf3m2k7i

After discussion with HTC engineer I submitted this as a bug report to Unity: http://fogbugz.unity3d.com/default.asp?1304082_gsk09e85lf3m2k7i

ViveSR_Log.zip Attached. The issue appears in Unity 2019.4.10f1 with SteamVR 1.14.16 and SRanipal Ruuntime 1.3.0.9, camera version 2.41.0-942e3e4.

Once we start the calibration process from Unity, using the SRanipal_Eye_API.LaunchEyeCalibration(IntPtr.Zero); the environment changes to the grey calibration screen and displays "Loading" with the loading animation. This disappears after about 5 seconds, and only the gray background remains. Previously, we would see an animation that would advise us on correct positioning of the headset. If we try to restart our application once the calibration has been started, our application freezes. This issue has appeared last week and it seems it follows after the SRanipal SW auto-updated. We have reproduced it on two different PCs.
