  1. 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
  2. Hi! I've been trying to get the Vive Pro Eye to work for a while now but am running into issues. In particular, I am unable to get the SRanipal robot tray icon to turn its eyes from orange to green and I've run out of ideas. I've been following the Getting Started guide but Step 3 says to "Make sure the VIVE Sranipal SDK works before going to the next step" and I am not entirely certain what that means in practice. It seems to be compressing a lot (like a potential whole other Getting Started Guide) into that one short sentence. I've downloaded and unzipped the SDK. I then downloaded and installed United and imported the package into the sample scene, as instructed in the SDK guide. I tried playing but nothing really happens so I can't verify if it's actually working or if the sample is just pretty plain. I've also had a bear of a time calibrating the Pro Eye. Out of the more than fifty times (over several days), I've only succeeded once, somewhere around the 30th attempt. Every other time, after following the dot, I get a "Calibration Failed" message. It would be helpful to know what exactly is causing the failure since the routine gets very frustrating if I don't know why it's failing. I've cleaned the lens, etc., but to no avail. I'm wondering if I'm missing something, the Getting Started Guide needs some serious editing, or the technology is really ready for use. Probably a bit of each...Thanks in advance for any help!
  3. Hello All, I've been developing an application using HTC Vive Trackers on Foots. When you play the scene the first thing I made user do is make a calibration. then user make sure that the trackers are on the right places. and on the next step, user select a scene to play and gets in and play. However, when user gets back to main menu I loose the calibration states of the trackers and user should calibrate it again before selecting next scene. What am I probobly missing, can you please help me? Kind regards, ukfdr.
  4. Is it possible to spectate during the eye calibration from HTC? I use Unity and start the eye calibration by calling SRanipal_Eye_API.LaunchEyeCalibration() the HTC Eye Calibration is neither visible from the Unity game window nor being picked up from a screen recorder like unity recorder v2. I would like/I need to help participants (especially children!) during the calibration step, and it would be great if I can see what they see. It is also possible to change the language that the eye calibration screen uses programmatically? Thanks, @Corvus @Daniel_Y @zzy
  5. @Corvus Is it possible to GET calibration data as byte array OR json (or any other data set) and SET it for different users via Unity app?
