Hi! @papr or any other pupil labs team, can you please tell me if its fine to use the output of the pupil player software (i.e. replay gaze position over world view) in a video which i am preparing to describe the experimental protocol for a research publication?

@user-b9c1bd Of course. Please cite Pupil appropriately https://docs.pupil-labs.com/core/academic-citation/#academic-citation

Anyone has used the Core to study attention or engagement (tracking blink rate, saccade and pupillometry)? Can you share you publication? Also, are there better mobile pupil tracker out there that is also easy to use, collect data and analyze (no lengthy calculation, code writing, manual subtraction of data...)?

This will be done while the subjects (students) participate in video lectures.

In the getting started document it says you should use the 2D detection algorithm for static experiments and the 3D model for experiments with a higher mobility. Is that still the case? Or is generally using the 3D Model better because we reduce slippage errors? (with regards to the worse precision?)

@user-6e3d0f Nothing has changed with that recommendation. The accuracy reached by the 2D mode is higher than that of the 3D mode. The 2D mode is however very prone to slippage and should thus only be used in static experiments where no slippage can occur.

Thanks
