  1. Hi @Adam Streck Apologies for only now getting back to you, I missed your message. I don't have my HMD (it's in my research lab and it's tough to get to with COVID-19 restrictions) so it's hard for me to test your code and troubleshoot. What I can say is that we ended up using a different workflow that with some tweaking seems to work for our needs. I'm posting the steps we took below. Let me know if you have any questions. We started off by setting up a raycast with the camera as the origin, and gaze direction. We took the hit point we got from the raycast and used WorldToScreenPoin
  2. @Tony PH Lin Hi there, I am a researcher and also need the monocular field of view in order for an analysis to work. Is there any way that information can be shared?
  3. Hi @nbhatia, can you clarify, when you mentioned that Tobii XR SDK works with convergence_distance_mm was it with the VIVE pro eye system? If yes, did you have to pay to be able to save/use the data from the Tobii XR SDK? Thanks so much, Av
  4. Hi @Hank_Li, Thanks for the idea! I think I've figured it out, it didn't end up being a calibration problem, it was an issue with the input to WorldToScreenPoint.
  5. Hi @Corvus I am trying to save eye position in screen coordinates (where the observer is looking in the scene in X,Y,Z pixels) for an analysis. For now I've been trying to raycast to get a hit point with world geometry, and to then convert that hit point to screen coordinates, but the values I'm getting seem off. When I tried going over the documentation, I didn't think focusInfo was quite what I needed. I looked again and I'm still unsure, can you clarify what focusInfo.point is? Thanks so much for your help! Avi
  6. Hi @AdamStreck I'm running into similar issues, did you ever resolve this problem?
