nbhatia Posted April 24, 2020 Share Posted April 24, 2020 Dear All, I am trying to find out if the support for the following parameters have been added in latest SDK i.e. Eye Tracking SDK (SRanipal) v1.1.0.1 as of 2020. In the previous posts on this forum, it has been reported than they are not supported. (Att: @Daniel_Y, @Corvus) Regards, Nitesh public bool convergence_distance_validity; public float convergence_distance_mm; Link to comment Share on other sites More sharing options...
traclabsar Posted May 19, 2020 Share Posted May 19, 2020 I'm finding the same thing (convergence distance is not implemented). I wanted to use this value to limit the range of a Unity raycast for detecting and recording what object the user is looking at at any given moment. I limit what objects the raycast will detect (don't need to know the user is looking at the sky or a wall) by assigning objects of interest to a specific layer and setting the raycast layermask to that, so most of the time the raycast is looking out to infinity. I figure that's inefficient, but maybe not. Link to comment Share on other sites More sharing options...
nbhatia Posted May 19, 2020 Author Share Posted May 19, 2020 This function seems to be working fine with Tobii XR SDK. For your work, Tobii’s G2OM implementation of finding gaze focused objects might as well help. I still have to check if both the sdks (SRAnipal and Tobii) can work together.

Av Posted August 20, 2020 Share Posted August 20, 2020 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 Link to comment Share on other sites More sharing options...
nbhatia Posted August 21, 2020 Author Share Posted August 21, 2020 Yup. Tobii XR SDK is free but EULA has to be accepted. Link to comment Share on other sites More sharing options...

Asish Posted August 19, 2021 Share Posted August 19, 2021 Dear All, I'm trying to calculate distance between gaze_origin(provided by API) and the target object using following code but the units are not same for these two points. So, how to get same type of coordinate system? var d = GameObject.Find("CubeObject").transform.position; var combine_gaze = eyeData.verbose_data.combined.eye_data.gaze_origin_mm; float dist = Vector3.Distance(d, combine_gaze); Thanks in advance Link to comment Share on other sites More sharing options...
