Dear @imarin18, Thank you for your fast reply. I will definitely look into this "eye validity" variable. We know for sure that the participant closed his eyes during this interval of missing data, so it's still weird that a parameter called "eye openess" returns the maximum value of 1 (meaning "eyes are open") for that entire interval. I'll let you know when we find a solution. Best regards, Klaas

Hi, I am trying to write a blink/missing data interpolation algorithm for the recorded pupil dilation in mm. To this extent, I was thinking of using the EyeOpeness parameter to identify when the pupil was not visible by the HMD and interpolate those specific values. However, when I plot the pupil size in mm (BLUE line) and the eye openess parameter (ORANGE line) on top of each other, there's a big chunck of missing data in the middle for which the pupil diameter is -1 (which means missing, I guess) but the eye openess parameter shows 1 (which means the eye is completely opened). This seems weird to me and makes the Eye Openess parameter useless, or am I missing something here? Thank you!
