Hi! I developed an outlier robust set-membership filter for gaze data in Pupil Invisible eye-tracking. The filter is able to suppress the outliers and non-Gaussian noise caused by blinking in the gaze data. The address of the dataset is: https://drive.google.com/file/d/1HiBZ3rUpkevK8RhsDluqEqs4wsaem7tW/view?usp=share_link. The paper is:https://ieeexplore.ieee.org/abstract/document/10054140/
Hi all, any suggestions to avoid, justify, or compensate for the sharp smoothing artefacts at the beginning of my pupil plot? Do you have a publication you can refer me to, which shows the same situation? Should I just crop the curve?
Hey All,
Has anyone used the Grip model from the paper Get a Grip - https://dl.acm.org/doi/10.1145/3314111.3319835 for detecting the point of regard? I am looking to understand how well it works under settings that are different from those reported in the paper. Any help will be highly appreciated.
Finally out this paper. Very tricky usage of Pupil Core. Check it out! https://twitter.com/NishizonoRyota/status/1659664510523953154 https://doi.org/10.1016/j.isci.2023.106803
Congratulations on the publication 🎉 Very cool to see Pupil Core used in this research 😎
Hi all, do you know of a study looking into how pupil dilation can be linked to sense of agency?
Hey @user-98789c 👋 I am not aware of studies that have explicitly looked into SoA measurements and pupil diameter but there are some other studies that might be relevant. Below a summary:
Pupil diameter and sense of embodiment: https://escholarship.org/uc/item/8rt963b9#author
Pupil diameter is a proxy of activity of the noradrenergic system and specifically the Locus Coeruleus (LC). There is evidence already from the 80's that when the animals move LC activity increases and pupil dilates. Movement very often has predictable sensory consequences. This might be relevant to your question considering again that the sense of agency is stronger when you generate a stimulus vs. passively perceiving it (imagine hearing your voice when actually producing it vs. hearing your voice from a video - in which case would you feel that you are the agent of what you hear?). There is plenty of work showing increased pupil diameter in "active" movement states. For animal work on that I highly recommend the work done by McGinley lab (e.g., https://pubmed.ncbi.nlm.nih.gov/26074005/ ). For human work, you can check this paper (https://www.sciencedirect.com/science/article/pii/S1053811922007169 ) and part of my own work as well (https://onlinelibrary.wiley.com/doi/10.1111/psyp.14156 and https://www.authorea.com/users/614297/articles/641446-the-multifaceted-nature-of-self-generation-effects-independent-and-interactive-effects-of-actions-predictability-and-delay-on-sensory-processing-and-memory-encoding-of-sounds).
Hey All
Hello all, Can you please point me to (as many) studies that you know that have done single-trial analyses on pupil dilation?
