Hi @thizizmyname, thanks for your query.. yes, that’s a very cool idea indeed that the eye tracker will auto recognise the user based on retinal image for example unfortunately it’s not a feature that’s available yet in our consumer eye trackers. As you say, for the time being, a 3rd party tool based on a webcam would be your best bet.
That being said, I will pass along your suggestions to the developers and perhaps there is some solution available that utitlises the eye trackers own camera images in this fashion. will keep you posted.
