What is criteria to distinct Fixation Begin/End/Data?

[Cheong-mok Bae]

I want to know,

In EyeX SDK, what is criteria to distinguish Fixation Begin/End/Data

distance from previous point? or fluctuation of eye angle? other data?

What factors are considered to distinguish?

Hi @cjdahrl (Cheong), I am afraid that we do not provide the specific values we used to distinguish a fixation however it is determined as the eye gaze resting within a specified area with a specific time window.

Therefore in relation to your question it is a calculation of both distance from previous point and time elapsed between points.
