  1. Hi, I'm new to this and I'm trying to set up SRanipal in Unreal so that I can get the eyetracking data. I have followed the manual and can get to the point where I have to enable the plugin, but it does not show up in the list of plugins in Unreal. Any ideas what could be wrong? I tried copying the unzipped 'Plugins' folder into the project folder and also tried copying the 'SRanipal' folder into the 'Plugins' folder of the game engine. Best, Maartje @Daniel_Y @zzy @Corvus
  2. Hello. I want to calculate the gaze point in Unreal Engine. I have some questions about EyeData. (I'm using Unreal Engine 4.22.3, SRanipal_Runtime 1.1.2.0, SRanipalSDK 1.1.0.1) 1. Shouldn't gaze_origin_mm be used to calculate the gaze point? Why EyeFocusSample doesn't use gaze_origin_mm? 2. Is eye_data_validata_bit_mask a value that is set a bit corresponding to SingleEyeDataValidity? For example, if only gaze_origin_mm and gaze_direction_normalized are valid, eye_data_validata_bit_mask is ((1<<SINGLE_EYE_DATA_GAZE_ORIGIN_VALIDITY) | (1<<SINGLE_EYE_DATA_GAZE_DIRECTION_VALIDITY))? (SingleEyeData::GetValidity() seems to be wrong.) 3. The convergence_distance_validity seems to be always FALSE. Is convergence_distance_mm supported now? Thank you.
  3. Help me! The line of sight is no longer displayed on the screen after calibration is complete. Also, it was displayed without problems until last week. If anyone knows a solution or cause, please let me know. Thank you. @Corvus @zzy @Daniel_Y
  4. Vive Pro Eye Calibration Initialization Error Troubleshooting Problem: Launching calibration shows error: "Initialization Failed" Solutions: - 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. - 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).
  5. Hello! I am developing with Unity2017.4.34f1 using Vive pro eye. In the project I developed, scene transitions occur frequently, but at that time, an error [[SRanipal] Initial Eye: DEVICE_NOT_FOUND] occurs and the eye tracking function stops responding. Please help me if you know the cause or solution of this problem. Thank you! @Daniel_Y @zzy
  6. Hello. Is it possible to display the eyes of the user wearing Vive pro eye as an infrared image on the monitor? It will be helpful if someone tells me.
  7. Cory, from HTC VIVE, will conduct a free workshop on Eye Tracking development using HTC VIVE’s SRAnipal SDK. Topics will include eye tracking, foveated rendering, variable-rate shading, and using eye tracking for avatar animations. If you are interested in using eye tracking or foveated rendering in your VR content then come to learn, network, ask questions, and try a demo! This workshop is free and opened to the public. You will not need a SIGGRAPH badge to attend. RSVP for your free ticket here This workshop is in partnership with LA Unity 3D Meetup, XRLA Meetup, and Two Bit Circus. There's going to be a strong & passionate community of XR developers attending, and it'll be a great opportunity to connect / network. Location: Two Bit Circus – 634 Mateo St, Los Angeles, California Date: 7/30/2019, Tuesday Time: 6:30pm - 9:00pm Hope to see you there!
