Eye movement velocity threshold for fixations

[Leo Strelen]

Hello,

I’m conducting an experiment to investigate differences in visual search behavior in VR and reality. For the VR part I’m using the XR SDK in Unity. Because I have to use a different algorithm to detect fixations in reality, I want to make sure they do that in a comparable way.
Is there a velocity threshold used to detect fixations on objects with the SDK or is there a possibility to use one? Or is that only possible with Ocumen?

Kind regards,
Leo

Hi Leo, I am afraid that fixation detection per se is only available with Ocumen, but the XR SDK does come with G20M

Which may suit your needs?
