Hi everyone, I have a quick question about how fixations are calculated within the Pupil Invisible glasses. What is the threshold used to determine fixations?

user-f43a29 10 April, 2025, 11:42:07

Hi @user-c3f0a4 , you can find this and other details in our Fixation Detector whitepaper, where the algorithm is detailed.

Hi, I used pupil invisible and got saccade velocity in pixels per second. is there a way to convert it into degree per second?

Hi @user-9e276a , we've also received your email and notified the Pupil Cloud team about your request. We will keep you updated.

Thanks @user-f43a29 . One additional question - the gaze data is given in pixels x and y coordinates but i want it to be normalized in 0-1 scale. how to do that?

Hi @user-9e276a , do you want it in normalized coordinates for the scene camera image or normalized coordinates on a surface in the environment, such as on a computer monitor?

Thanks @user-f43a29 for prompt response. I am using a driving simulator and my scene is not static. There is motion.

user-f43a29 17 April, 2025, 08:09:29

Motion is okay, but then you want to know what position or pixel on the driving simulator they look at, so to say?

I need a gaze density distribution. Something like the attached one.

Hi all. I have one question regarding the invisible. Is it possible to use for the people who are using contact lenses?

user-480f4c 24 April, 2025, 13:33:54

Hi @user-a9f703! Yes, Pupil Invisible works with contact lenses. - contact lenses do not negatively impact the performance of gaze estimation.
