nini613 Posted July 22, 2020 Share Posted July 22, 2020 Hello, I'm trying to understand the figure, 1. I've noticed the SDK example that float *gaze = eye_data.verbose_data.left.gaze_direction_normalized.elem_; Is the coordinate of right or left Gaze_Direction_Normalized as same as the coordinate where user is looking at? If no, how to calculate the coordinate where the user is looking at? 2. I've read the comment that "The data `gaze_origin_mm` represents to your eye location and the origin point is in the middle of your HMD." Is combined.eye_data.gaze_origin_mm equal to the combine gaze origin of the figure? but it's not always be (0, 0, 0) Could I guess that the gaze origin is as same as the starting point of eye? I don't really know how this parameter works. Thanks for helping me to understand this figure. @Daniel_Y @Corvus Link to comment Share on other sites More sharing options...
