  1. Hi, I am unable to receive eye data at 120 Hz. On several Vive Pro Eye headsets I am getting very low data report rates using the C++ SRAnipal API. Using the C++ sample project included the SRanipal SDK (link), I print out gaze data once every 120 samples. The data reports at a rate much slower than 120 Hz: ~30Hz when executing ViveSR::anipal::Eye::GetEyeData in a loop ~60Hz when executing callback My SRanipal runtime and tobii platform information is attached. Vive software and drivers are up to date.
  2. Application: Academic Research Goals: Install SDK ----------------------------- [ X ] Get Eye Gaze ------------------------- [ ] Get Fixation --------------------------- [ ] Get Pupil Dilation ------------------- [ ] Run Subjects & Get Tenure ----- [ ] Question: How do I reference the SDK's framework / API to extract close to real-time eye tracking data that prints either in a data.frame or CSV file. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Hi there, I've been able to get the VR and eye tracking set up and working per a previous thread with UE 4.25.3 and have a demo with VR functional. The only thing is I'm not sure where to go from here to get the SDK to write/print data to a csv or similar file. Presently I don't need any eye tracking interactions within the VR environment so the dartboards and mannequin head are useful in that they show this data exists but I need to get that data out of whatever loop it is in and write it to a data file for processing in statistical programs and the like. @MariosBikos_HTC , you've been a great help so far. Let me know if you or another HTC fellow are the right ones to ask about this function. Once I get something functional I'll definitely be sharing it for future folks in my position.
