We want evaluate the pupil size in our study via eye-tracker tobii t60. espacially we are interested in DiameterPupilLeftEye and DiameterPupilRightEye.

we got question related to the following three kinds of figures that are presented by the "DiameterPupil": what are their differences?

2.934.003 (2.934 mm?)
292.527 (???)
-1 (no eye-contact?)

We also find a respectable difference between the right and the left eye size. Sometimes the differnece is very small and somtimes it’s big.
Do you know about a good solution about how to react to this problem?

Thank you for your answers

In my last experiment used this Tobii, it provides detailed analysis and interpretation of the eye tracking. The three readings you are getting are nothing but fixation filter implementations reading which you have fixed earlier or as per default. You can further change them as set as per your needs available for eye movement classifications!!
