Can't get this to work 😞 I keep getting the "This HMD doest NOT has eye-tracking feature, Error : 0" in my log, even though I've tried everything in this thread. I don't see "Eyechip" in devices, maybe that has something to do with it? But I don't know how to install that manually. Using a RTX 3090 and AMD Ryzen 9 3900X.

I see the EyeChip device hidden in device manager, with the error Currently, this hardware device is not connected to the computer. (Code 45). Could this be why? Any ideas how to fix this?

Hi guys I ended up fixing my error by removing Vive console and SRanipal 1.3.6.6 and installing SRanipal 1.3.1.1 instead. As soon as I plugged it in I got a message that the device was updating and then the robot finally turned orange and I was able to calibrate. Hope this helps someone!

It seems like many are still struggling with the eye tracking in the Vive Pro Eye...  

I recommend simpleXR!  https://github.com/unity-sXR/sXR

Before downloading the project, uninstall SRanipal using the uninstaller (don't just delete it).  Install Vive Console for SteamVR (through Steam). It comes with the latest SRanipal.  

Once you have  Vive Console, you need to add the SRanipal SDK to your Unity project.  https://developer-express.vive.com/resources/vive-sense/eye-and-facial-tracking-sdk/download/latest/

Install it by doing Assets->Import package-> Custom package.  Select the unity package for the sdk.  

If you've installed everything properly, you should be able to get all the eyetracker info by using sxr.StartRecordingEyeTrackerInfo().  You can access the eyetracker info in real time by making calls to the GazeHandler.Instance

I'll be launching a Vive Pro Eye tutorial for simpleXR early next week.  Feel free to reach out with any questions

I'll still be making a complete video walkthrough early next week, but this should be helpful:

I won't be able to test some of the newer functions until Monday.  If someone gets an error feel free to reach out (sxr.unity@gmail.com)

Vive Pro Eye Calibration Initialization Error Troubleshooting

Problem:
Launching calibration shows error: "Initialization Failed"

Solutions:
- Run "EyeCalibration.exe" manually in C:\Program Files\VIVE\SRanipal\tools\eye_calibration
- Power off/on PC & Link Box.
- Run 'sr_runtime.exe' as Admin. Default install path: 'C:\Program Files (x86)\VIVE\SRanipal'.
- Update SteamVR Runtime.
- Update graphics card drivers.
- Navigate to "Change User Account Control settings" via Windows Settings search or start menu search. Change to "Never Notify" and click "OK".
- Possible issue with some models of MSI laptops fixed with rollback to earlier NVIDIA driver. Fresh install of NVIDIA driver 417.71 (GPU BIOS not being updated and it does not support the latest NVIDIA driver).
- Uninstall 'VIVE_SRaniaplInstaller' & 'Tobii VRU02 Runtime'. Restart and Install latest 'VIVE_SRanipalInstaller_1.1.0.1.msi'. Plug in HMD and wait for any updates to complete.
- Update motherboard integrated Intel Graphics Driver (fixes system reference to incorrect openCL.dll (intel) instead of NVidia).
- Disable integrated graphic card
- Possible issue with wireless adapter, try running calibration with wired.
- Possible issues with early dev kits.

 

Check System Requirements:
- Use DisplayPort, mini-DisplayPort, or USB-C output from the dedicated GPU.
- Windows 8.1 or later (64-bit).

 

Problem:

Error in logs: "This HMD doest NOT has eye-tracking feature, Error : -5"

Solutions:

- Launch "SR_Runtime" and start calibration or eye tracking application
- Check Device Manager for "EyeChip" under "Universal Serial Bus Devices"
- Check Services for "Tobii VRU02 Runtime"
- Remove any other Tobii services installed
- Disconnect any other eye tracking devices attached

 

 

 

 

 

What if not have EyeChip in Device Manager?

I have been experiencing a Calibration Initialization Error recently, and I've noticed that the program crashes when calling SRanipal_Eye_Framework. I suspect that this issue might be related to the new version of SteamVR (v1.27.5). I didn't encounter this problem with v1.18.7, or could it be due to some other reason?

Has anyone else encountered the same problem recently and figured out how to resolve this problem?
