Hi, I am using SRanipal to collect and process gaze data, and several times in the process I have to use gaze rays, which I get with the provided method SRanipal_Eye_v2.GetGazeRay. Despite this method returning the origin of the ray, I have seen in several classes in the SDK that Camera.main.transform.position or Camera.main.transform.position - Camera.main.transform.up * 0.05f are used instead. I tried comparing both, and results are very similar, but not exactly the same, as shown below (in this example I simply get the gaze ray for combined eyes, raycast it in my scene, and display hits). I am thus wondering which value should be used for optimal precision, as this is used in a scientific research and such offset is very impactful on the results. I look forward to hearing back from you, Regards, Vivien

Hi @Hank_Li Do you have any update on when this feature will be available? As one year after your post, I don't know if the SDK version has changed since, but the system timestamps still aren't available. Regards, Vivien
