Klary Posted March 27 Share Posted March 27 Hi everyone, I've been trying out the face tracker for the XR Elite with OpenXR (https://registry.khronos.org/OpenXR/specs/1.0/html/xrspec.html#XR_HTC_facial_tracking). I noticed that the blend shape weights for XR_EYE_EXPRESSION_LEFT_WIDE_HTC and XR_EYE_EXPRESSION_RIGHT_WIDE_HTC are always 0. The others seem to work fine. Does the eye tracker not support these two blend shapes? On the official website for the tracker (https://business.vive.com/uk/product/vive-full-face-tracker/) it seems like the female example moves the eyebrows slightly. I would be grateful for any insights! Thank you and best, Klary Link to comment Share on other sites More sharing options...
VIVE_chengnay Posted April 12 Share Posted April 12 Hi @Klary, Currently, these two values are not supported. Will this cause any problem during your development? Link to comment Share on other sites More sharing options...
Klary Posted Tuesday at 02:47 PM Author Share Posted Tuesday at 02:47 PM Hi @VIVE_chengnay and thank you for your response. Sorry for my late reply, I did not follow the post. Does the hardware of the face tracker not support it, or is it just not connected in software? Would I have access to them if I used SRanipal?

Without them some emotions are very hard to express. Previous users seemed to get the blendshapes with v2 eye data from SRanipal: Thank you and best, Klary Link to comment Share on other sites More sharing options...
VIVE_chengnay Posted yesterday at 01:54 AM Share Posted yesterday at 01:54 AM Hi @Klary, SRanipal only works for Vive Pro Eye hardware. 11 hours ago, Klary said: Does the hardware of the face tracker not support it, or is it just not connected in software? I was told that those two values are not supported now. I will check internally. Link to comment Share on other sites More sharing options...
VIVE_chengnay Posted 21 hours ago Share Posted 21 hours ago Hi @Klary, Maybe I am wrong with SRanipal statement. I will double check again today and reply you later. 1 Link to comment Share on other sites More sharing options...
VIVE_chengnay Posted 12 hours ago Share Posted 12 hours ago Hi @Klary, SRanipal does support data from XR Elite's face tracker mapping to SR runtime. But, it does not support OpenXR. My colleague told me that Wave plugin does support right and left wide values. Link to comment Share on other sites More sharing options...
