And why do I get so many bad pixels in the live stream?

hello i am using meta quest 2 and i want to integrate pupil lab addon for the eye tracking.

for my research i want to capture the live image of the user is pupil product able to provide me that raw image data?

Hi @user-2e0f13! Our eye tracking systems do expose live images of the wearer's pupils. That said, we don't have a turnkey solution for something like the Quest 2. It would require prototyping of mounts to fit our hardware into the HMD, according to the geometries and constraints of the system.

One option would be to get a de-cased version of our existing binocular VR Add-on: https://pupil-labs.com/products/vr-ar/.

Another would be to go for a 'bare metal' version of our newest eye tracker, Neon: https://pupil-labs.com/products/neon/shop. We offer access to the 3D geometries of the nest and module to enable prototyping: https://github.com/pupil-labs/neon-geometry.

Both options have their pros and cons. Neon would usually get my vote since it samples gaze in real-time at 200 Hz and is significantly more user friendly when compared to the VR Add-on which requires user-calibration and a very controlled environment to get the best results.

That said, if you can share some further details of your use-case, I can try to offer more concrete advice.

any other option or any vr headset which can give me the raw image data?

Hi @user-2e0f13! Our existing VR Add-ons do fit the HTC Vive, Vive Pro and Vive Cosmos. Using that combination of eye tracking HW and headset will get you the raw eye image data

The Eyelink toolbox is for SR-Research Eyelink gazetrackers, not Pupil Labs eyetrackers, no?

Hi @user-cdcab0, I don't know if this is the proper place to ask the following, I hope so. I need to extract .csv for pupils movements from several folders containing pupil recordings, and I was wondering if there is a faster way rather than simply drag and dropping the folder on Pupil Player. Is there any proper reference on the documentation or a way through source code to automatize this process? Thank you in advance.

Sorry to ask another question at the same time, but i was wondering if its possible to activate a camera via bluetooth

@user-cdcab0

Sorry bout my english. My main question is this: can i use the code to run in a mobile device? If not, the data can communicate through an app

Can you explain to me the second topic ?

Our Neon headset plugs into an included Android device that runs an app called Neon Companion. This app records data from the headset and can also stream the data to another machine in real time. It's the standard way of using our Neon headset

Thanks a lot! Do you know by any chance if the pointed "info.csv" in player_methods.py module, line 196 inside load_meta_info func (I'm referring to the version in the repo you linked me) has been replaced in more recent releases by a JSON named info.player?

Hi dom, thanks to your help I made huge progresses. Just a question, do you have any suggestion in extracting gaze_positions as well pupils_positions? I'm working with the last project you pinned and it only provides pupils_positions.csv files, and I wonder if there are also related project for the gaze files. Thank you in advance!

Hello, I bought the DIY pupil lab eye tracker and am in the process of setting it up. I tried to install the pupil software (Linux version) on Raspbian but it would not install. Could you guide me on how to get it installed on Raspbian?
