  1. Hi Everyone! I'm working with HTC Pro Eye in Unity using SRanipal. I would like to know if there'se any chance to change Gaze Ray Sample 2; creating two different gaze rays, for each eyes. And if it possible, it is possible obtain data from each eye? Otherwise, is possible to change Gaze Ray form, with a panel of my creation create inside Unity? I mean, i create using Panels a particular effetc which simulate low vision conditions, and i would like to use this panels, as a replacement of "pink" ray gaze offered in the SDK. Thanks for the help.
  2. I'm trying to display a UI element in the position of the gaze collision. I found out that just using: Camera.main.WorldToScreenPoint(collision.position, Camera.MonoOrStereoscopicEye.Left); does not fully work for the "LeftEye" display - there seems to be some screen-cropping going on (about 15% on each side). Does anybody have a way how to reliably obtain a screenpoint from world point in SteamVR in Unity please? @Daniel_Y @Corvus
  3. Hi everyone, I'm struggling with reaching the specified sampling rate of 120 Hz (8.33 ms) on a VIVE Pro Eye HMD. We use the SRanipal eye callback: SRanipal_Eye_v2.WrapperRegisterEyeDataCallback() in a script, derived from MonoBehaviour. The registered callback is only called every 14~16 ms, which leads to approx. 62 Hz. Way below the targeted 120 Hz. I think the PC specs are quite decent and should allow for 120 Hz sampling: Windows 10Pro Intel i7-10750H (specs can be found here) 32GB Ram GeForce RTX 2070 with Max-Q Design Following tool versions
  4. Hello Forum, We are a group of students using HTC Vive Pro eye for Eye Tracking as part of our academic project. We need to get the eye tracking data at its maximum capture frequency, having tried the following methods we still fail to capture data at 120Hz, 1. We tried to set the Application.targetFrameRate to more than the default targetFrameRate but it did not work as the number of records did not change. We added it to the start function as in the link below: https://docs.unity3d.com/ScriptReference/Application-targetFrameRate.html 2. We tried implementing threads as mention
  5. 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
  6. How do I get the current timestamp from the eye tracker in Unity? @Corvus @Daniel_Y @Andy.YC_Wang
  7. In this post, I am going to show you how to integrate Variable Rate Shading (VRS) with your Unreal Engine project in order to enable Foveated Rendering using the HTC Vive Pro Eye headset. This article is going to focus on Unreal Engine. If you are using Unity instead of Unreal Engine then you can use the Vive Foveated Rendering plugin from the Unity Asset Store or the Github page. It is assumed that you’re somewhat familiar with Unreal Engine, C++ and Blueprints. Requirements HTC Vive Pro Eye headset VR Ready Quadro (Quadro Desktop: Quadro 4000 card and higher, Quadr
  8. Hello all, I am desperate: Since Monday our eye tracking is not working anymore. As you can see in the attached Tobii-Logfile, SRanipal requires to update the firmware of the eye tracking camera. This fails and is immediately retried, resulting in an endless loop of failed firmware updates. Unfortunately this firmware update is required and prevents the regular functioning. Also the EyeChip-device is always ejected and recognized again during this process. The HTC-Vive headset and ts cameras are working fine. I tried already many things: Several SRanipal-Versions: 1.0.2.0 and 1
  9. Hello, I have some questions, I would be really glad if you could help me : 1. I'm doing an experiment using HTC PRO EYE and Unity and I am looking for a "glossary of term" that will help me understand the meaning of each variable, and the scale of possible values. Can you refer me to a relevant link? (For example for variables: Pupil Position, Pupil Diameter, validation) 2. I am looking for a variable that will return information about the confidence level of the pupil recognition. I thought that - .eye_data_validata_bit_mask Will help me, but it gives me a constant resul
  10. Hi - I would like to entirely eliminate the head motion sensor input on the HTC vive pro eye such that if the user moves their head, the display does not change and keeps the same view / screen. I know this is a bizarre request - it is for an eye tracking study with no external variables coming into play), but any help would be appreciated on whereto look in the SDK. Thank you so much!
  11. Problem I'm having some difficulty getting the plugin for unreal engine installed for the Vive Pro Eye Headset. Following the directions in the documentation leads to compile errors when I go to launch the project. In short, I can't get the plugin to compile or the project to load correctly. Done: [X] - Installed and running steam VR [X] - Installed and running SR_Runtime [X] - Calibrated Eye Tracker in Steam VR Error Trigger Pasted unzipped unreal plugin into C++ blank UE4 project. Returned message from unreal: Result of
  12. Hello, I would like to ask if it is possible to adjust (in code or in the configuration) the speed of the moving point during the eye calibration using the HTC Vive Pro Eye. We are using the HTC Vive Pro Eye in a clinical center for visual tests. There are some visually impaired patients who are not able to follow the moving point since it is moving too fast for them. Any help would be appreciated. @Jad @Corvus @Daniel_Y
  13. Hello I bought vive pro eye to do eye tracking at unity. But, when I start eye tracking calibration in steamVR. adjust the headset up and down to fit the frame. Even if the headset up and down, the image does not change. and I can't go next step...just stop ; - ; In addition, the camera in SRruntime is not recognized. (And I connect my vive port to graphics card connected to the monitor.) I reinstall several times after deleting all the program(steamVR, SRruntime, etc,,,). SteamVR also 'Camera communication failed.' I think it is a problem wit

  16. 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.
  17. 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
  18. Specifically, I need to know where my participants will be looking at a precise time, so the video and the samples from the EyeData object must be perfectly aligned in time. I am also wondering what the equation is to calculate where the participant is looking from the left and right gaze_origins and the left and right gaze_directions or if there is a better way than trying to compute where the participant is looking in VR from those 4 sets of values. @Corvus @Daniel_Y
  19. 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. T
