Hi team. Can you guys tell me how to download the raw Android data from the cloud? I am trying to test the neon player.

Hi, could I ask what does 'timestep' columns represent in 'gaze.csv'file exported by neon by pupil? as the difference of each column seems vary! Thank you in advance for your help!

Sorry for disurbing you, I believe the cloud is temporarily not accessible at this moment Could you guys please check with this? Thank you so much!!

Thank you so much !!!

Is it possible to know the frame index of world video in the gaze file? I mean how to know what all gaze fall in a particular frame. Currently, this information is not in the gaze.csv file. Also, the start timestamp of gaze.csv and world_timestamps.csv is different. Any suggestions?

Hi, we had several recordings that couldn't be played either locally on the phone or on Pupil Cloud. All recordings were recorded today. The error message said "gaze pipeline was broken..." Can we have some help on this please? Thanks so much!

Hello good evening, are there any issues regarding Pupil Cloud at the moment after the scheduled maintenance? I wasn't able to generate an image mapper out of 3 videos (Error says "The enrichment could not be computed based on the selected scanning video") and when trying to download a simple video with the gaze overlay it says "Error: Please contact info+cloud-support@pupil-labs.com for support) Thanks in advance!

Neon Player debugging

Hey, is it possible for the "Just act natural" frame to remove the lenses? I know that this was possible with the PupilInvisible

Hi PupilLabs, we're working with real-time streams from multiple Neon devices. It seems like the decoding of scene frames from the RTSP stream is limiting the number of devices we can stream at a time using the Python Realtime API. Is it possible to reduce the resolution of scene frames from 1600*1200 so the decoding is faster?

Hi - I am trying to set up PsychoPy. I am at the stage of details about 'remote address' and 'remote port'' (step 4 in this guide https://www.psychopy.org/api/iohub/device/eyetracker_interface/PupilLabs_Neon_Implementation_Notes.html#setting-up-the-eye-tracker). I am confused about how it works with more than one eye-trackers. I have two (therefore two IP addresses) and would like to set up an experiment where the same trigger is sent to both devices connected on the same network. Is that possible?

Hi! Pupil lab support team. I used the marker reference enrichment to analyse data through pupil could via the application of apriltags. I would like to ask how the pixels data in surface positions tranfer into cm or mm ? Or in which way should I interpret them.

Im trying to stream the glasses' camera directly into VLC, I was using rtsp://[phone_ip]:8086/axis-media/media.amp?camera=world&timestamp=0&videocodec=h264, it was able to connect but I am not seeing any output. I took that path from the RTSP OPTIONS message sent in the PI Monitor websocket connection

If anyone from PupilLabs also has some insight on this that would be awesome! 🙂

Using ths axis-media url works in an OBS media source, im thinking VLC can't handle paramaters in the URL?

The end goal is to use FFMPEG to decode many streams on an NVIDIA GPU

using ?camera=sdfas produces an immediate error, so using ?camera=world seems to connect fine, just again, no output

I am on VLC 3.0.11

from this, where it is attempting to connect i assume

Do you have FFMPEG installed? If so, you could try this: ffplay -fflags nobuffer -flags low_delay -framedrop "rtsp://[IP]:8086?camera=world"

If not, you may get a little more info out of VLC by launching it on the command line

yup, works through ffmpeg, strange how VLC is the only issue

That is a bit of a headscratcher. Can you try launching VLC from the commandline?

vlc "rtsp://[IP]:8086?camera=world"

It looks like you're on Windows, so you may need to specify the full path to VLC

same result

But any additional messages on the command line output?

nope, command line output is empty

Hm. Well, did you specifically need support in VLC?

no, would have just been nice, the end goal was to run it through ffmpeg so thank you for helping with that!

Hey! We are having trouble with our companion app being connected to the servers. The recordings are not being uploaded. We have updated the app and the firmware. Tried reconnecting to the network but nothing seems to fix the issue. Please advise on how to fix!

Hi, anyone tried to connect a bundled OnePlus 8T (Android 11) to Apple Silicon Mac? I am trying it using Android File Transfer / Open MTP, but none works.

Hello, we are using the web interface to stream the video from the Neon glasses using the phone IP indicated on the Neon companion, but regularly either the video or the gaze is freezing. Is it normal? We have to close and open again the browser, sometimes two or three times to fix it. Did you observe this as well ? And if so, have you some ideas to avoid this problem ? Thanks !

Hi, Is there any plan to be able to obtain real-time measurements of pupilometry data? My understanding is that this is only available after uploading to Pupil Cloud.

Hello everybody 🙂 Im from the university of Ulm and we just bought a couple of the pupil neon eye tracker, and they are working splendid! So we are really happy about them. 🙂 I have question about the parameters: Is there any way to find out how long the gaze has to rest in order for it to count as an fixations, saccade etc.? and is there any way to change these parameters? I looked through your homepage but coulnd´t find anything, so if sb could help me, that´d be great!

Also to tell you that the audio recording was activated on the companion but we figured out after 6 videos that it didn't record the audio. We had to toggle off and on again the audio recording to make it work. Very unfortunate, please check this issue

Audio missing

Hello, do you know what wavelengths are used in infrared by eye tracking glasses? Is interference possible with other devices in 780 and 850 nanometers?

Hey Pupil Labs team,

We need to know which gaze- and fixation- data points belong to which video frame. In Core, you provide the ‘start_frame_index’ for every fixation and the ‘frame_index’ for every gaze (https://docs.pupil-labs.com/core/software/pupil-player/#fixation-export). We would need something similar. Because of this missing information, we tried to synchronize gaze.csv and world_timestamps.csv with their closest minimum “timestamp [ns]”. We take the “timestamp [ns]” from the gaze and find the corresponding frame. However, the coordinates do not align with the red circle (image).

Therefore, the questions are:

• How do you calculate the red circle?
• How can we find out what the person was actually looking at on a certain frame?
• Could you please share the code or the documentation on how gaze overlay is done in Neon Player?

(image)[The frame is from gaze overly enhancement of the video and blue dots are the gaze coordinates we exported from gaze.csv]

Also as full reference this is the error I get. I have already installed the C++ build tools suggested in the error and restarted my laptop.

Hi, @user-cdcab0 I am having an issue with my pupil lab eye tracker it's not connecting to the phone

Hi @user-cdcab0, Could you please help! My neon companion stopped connecting to the phone (1plus 10 Pro) after making some continuous vibrations coupled with an error display. I have tried to update the firmware but the issue still persists.

Hello, I am interested in purchasing a Pupil Neon, can someone provide me with a sample data file output so I can review it? Does the Neon require paid software?

Hi, I have a question about Pupil Cloud. I am trying to obtain ethical approval to use the Neon in a study. I want to use your Pupil Cloud services, but my Research Ethics Board wants to know whether the transfer of this data to your servers is secure. Is the data encrypted before transfer?

EDIT: It would also be great to know whether the data is stored on your servers in an encrypted state as well.

Hello! I would like to use the data output from the neon device to predict 6d camera pose (relative 3d rotation + 3d translation) using visual-inertial odometry methods. However, it seems that these methods require magnetometer readings from the IMU device. After looking through the IMU manufaturers datasheet (https://invensense.tdk.com/download-pdf/icm-20948-datasheet/) it seems that it has two modes: 1) first mode uses the integrated digital motion processor (DMP), which outputs a quaternion but no magnetometer readings, and 2) second mode does not use DMP and so does not output a quaternion, but does return magnetometer readings. So basically, using the DMP throws away magnetometer readings, but returns quaternion. Does anyone here know how to set the IMU device to the second mode which returns the magnetometer readings? Thanks!

Also, if anyone has experience with this kind of thing, I would greatly appreciate any tips/suggestions/experiences! Thanks

Hi! Is there any way to get the scene_camera.json file? Here https://docs.pupil-labs.com/neon/data-collection/data-format/, it says it's included in the recordings folder, but I can't seem to find it

Hi, I have a question regarding the relation between the timestamps and the video in data exported from a neon recording in the pupil cloud. The enrichment_info.txt points to https://docs.pupil-labs.com/cloud/enrichments/#raw-data-exporter, but unfortunately, this does not seem to exist. I am currently working under the assumption that the "start_time" in the info.json corresponds to the start time of the video, i.e. I can get the corresponding video time by subtracting that start time from the "timestamp [ns]" (in both gaze.csv and world_timestamps.csv). Is this assumption correct?

Hello! I saw on the website that pupillometry data and eye state are now supposedly available on pupil cloud now. Unless I'm looking in the wrong place, where do I go to access this data? There doesn't seem to be any new enrichments and there are no pupillometry related csv files in the data exports. Thanks!

Hi @user-328c63 ! Recordings made with the Companion App 2.7.4 or above should already have a new CSV file named 3d_eye_states.csv https://docs.pupil-labs.com/neon/data-collection/data-format/#_3d-eye-states-csv that contains pupillometry and eye state. If that's not the case or you need an older recording to be reprocessed, please let us know.

You can reach out to us by email [email removed] with a list of recording ids or workspace ids that you would like us to reprocess for pupil size.

Hi, I am going through data I collected using pupil capture. However nearly every file has been misnamed. This can not be a result of me mislabeling the files before hand as I backed up the files by screen recording. For the screen recordings I can see that I entered the correct names next to where it says “recording session name” but when I view the files in pupil player most have the wrong name. Is there a way to fix this, and how can I prevent this from happening again in the future? Thanks!

Hello! We've received our neon glasses this week (yay)! I've been able to test them both glasses for a short time and with one of the two, neon companion has trouble displaying the gaze for some reason. When I uploaded the recording, after processing, the gaze data was present, I just couldn't display it in the stream or the preview of the app (or when trying to set an offset)

I think, since the gaze stream was there in the recording, maybe this is a software issue in the companion app? I need to test further, but any help in getting to the bottom of it would be greatly appreciated

the visualization shows up for the first few frames and then nothing

I'll try reinstalling the companion app, maybe something is up there

hm no, this is persisting :/

thank you, I shall do that 🙂

I found a difference

the eye preview screen looks persistently fine on the pair that is working

but on the other pair, it looks like the whole frame is shifted up/down and maybe that isn't just a display error, maybe it impacts the live preview

when I upload a recording to the cloud and something didn't work out, can I reupload the recordings somehow?

the problem was, something didn't work during upload, so the recordings were stuck processing

I "trashed" the two broken recordings on the cloud web interface, but locally, the companion apps tell me the recordings are in the cloud, so I can't try and upload them again

Hi @user-1391e7 ! I have replied to you by email. The trash only removes the recordings from Cloud, not from the phone.

You can access the trash and restore them by clicking on the three dots of the search bar, and selecting "Show trashed"

A general question with regards to the companion app:

I saw that I can enable/disable audio recording in the companion app, which is great. For studies, in which the recording of video is an issue (meaning all we're allowed to record is general eye movement behaviours, but not the world around participants), can I disable video recording as well?

with the pupil invisible glasses, the workaround was to just disconnect the world-camera 🙂

You can not disable the scene camera yet, but you can occlude it. If you would like us to prioritise this feature, please suggest it here.

Additionally, note that you can disable scene video upload to the Cloud for any Workspace you choose, when creating it you will find a toggle to select it.

by occlude, you mean I could just cover up the lens? .. I didn't think of that, that's a very easy solution ^^

the workspace options are awesome! very cool, ty

we always have to take great care with regards to rights to privacy, so any extra control there helps a lot

I was thinking I'd use a small piece of thick paper and tape over that, so then there's no contact between lens and anything sticky

also, the corrective lens swapping is great, really love the solution there.

the little screwdriver that came with the glasses fits into the center piece, does that mean I could in theory swap the frame for a different one?

although, the frame must have something else neat inside, right? since you're connecting that to the usb cable

maybe the one thing I'm worried about with the glasses for now. accidentally bending the cable over the course of the next year or so

There is one version under Specifications, called "Ready, Set, Go", which I can't find in the shop? Is that a preview of a version yet to come or was that a prototype you decided against selling later?

Hi Pupil Labs team 🙂 You mention a performance evaluation in a white paper coming this year (https://pupil-labs.com/products/neon/specs). Is there any news on this?

Hey everyone!! I'm trying to use the recently released blink detection algorithm Jupyter notebook, but even after installing the requirements I'm getting a ModuleNotFoundError regarding the pikit module. I tried installing the module separately, but it didn't solve the problem. I also changed my python version, but the problem persists. Has anyone been through this too and could help me?

Hello everyone! How can ı export the data in csv format ?

https://docs.pupil-labs.com/neon/data-collection/data-format/ Can I download it directly in csv format from neon companion or pupilcloud? In the download options, it downloads as a code in json format. Can I convert this code in Python and get csv format this way? Even though I examined this page, I would like to say that unfortunately I cannot fully understand it. How can I download my record in CSV format in the simplest way ?

Hi everyone! Could someone please tell me where I have to upload the reference image and the reference surroundin video? Also in my case http://neon.local:8080/ doesn´t work. Last thing: where can I find the steps for the calibration process for Neon - eve though it doesn´t necessarily need some, I got the information that it´s recommended.

Thank you! Where can I download the Neon Monitor App for Mac?

And yes, all of the devices are connected with the same WiFi and the URL doesn´t lead anywhere...

Still nothing: Die Website ist nicht erreichbarDie DNS-Adresse von neon.local wurde nicht gefunden. Eine Problemdiagnose wird durchgeführt. DNS_PROBE_STARTED

page not found

yes

but it also didn´t work with other wifi networks...

That worked, thank you so much!

Last question regarding the face mapper: I can´t figure out how to implement the face mapper into the Cloud. Do I need to program myself and download some training data?

thank you so much!

Hello guys, can you help me with the "waiting for DNS service?" RTSP iconnections s irregular across browsers and networks. Not sure what is missing.

Hello again. Is that usual that it takes more than 10 minutes (still on going) for the reference and the face mapper to run? (each)

Hi, I am having an issue with the neon companion live monitor application. It seems that I have a pair of glasses that just doesnt produce a video when connecting to the live monitor. the gaze circle is correct but the video itself is just permanently loading on a gray screen. I have another pair of glasses that I tested with a different phone and it works just fine. Both phones are running the same versions of the neon companion app.

Hi, I have been having a problem with Pupil Cloud where I cannot download the Time Series data. The download starts, but fails around somewhere between 23 and 32 MB. It gives me a "Check internet connection" error message.

I have verified that my internet connection is not the problem. I have a consistent connection and am able to download similarly large files from other website (e.g., Google Drive). Most of the recordings are 1 to 1.5 hours long, so they are quite large, but I haven't had this problem in the past. It started last Friday or so. Is there anything I can do to resolve the issue?

Hi! Is there anyway to get the magnetometer data? Or is there any output data on the magnetic north?

Hi! Is it possible to use the companion app for the neon without account and without internet?

Yes, thank you very much!

Hi guys, I am running into an "Internal Server Error" when trying to delete recordings from the Pupil Cloud. Would you know how to address this?

Hey Pupil Labs,

In our data, we noticed a mismatch between the gaze data provided in your gaze overlay enrichment and plotting the gaze data from the csv using your code from the repository (https://github.com/pupil-labs/densepose-module/blob/main/src/pupil_labs/dense_pose/main.py). We do not understand why there is an offset, specifically a very visible delay, between the gaze data from the CSV file (gaze.csv and world_timestamps.csv) and the overlay circle. This leads us to the following questions: 1. Why is the data from the csv and the data in the video desynchronized (the gaze circle in the video lagging behind the csv data) even if we use the code from your repository?

1. How can we get the correct gaze coordinates(the exact position where the person is looking at) for each given frame, since there is obviously a time shift when using the version from your GitHub? Here is a visualization of the observed problem. The following video is downloaded from Cloud Pupil, features the normal gaze overlay enrichment (indicated by a large red circle). Our team reproduces the gaze coordinates using the code from your repository mentioned above (marked by a small red circle). As you can see, the large circle lags behind the gaze data from the CSV files. The script provided in the attachment, named sample.py, is a modified version derived from your repository. Its purpose is to synchronize the world_timestamp.csv and gaze.csv files.

Hi Neil. Here are the results from the

Hi @user-a64a96 ! I noticed that the scene video is missing from the files you shared, which is necessary for me to understand what is going on. However, I have an idea about what might be happening. Did you try to plot the CSV data on the gaze overlay video instead of the original video?

Normally, eye cameras start slightly earlier than the scene camera after you press the record button. We don't throw away data, while waiting for the sensor and this means you have some gaze points over grey frames.

The video renderer / gaze overlay will not take this section of grey frames that appear at the beginning of the video in Cloud, and this will result on different video lengths, which could have caused this issue. What happens if you use the video downloaded from "Timeseries CSV + Video" ?

Hi@user-a64a96! I had a deeper look at the code that you shared, there are parts that are not necessary in your code, like multiplying by 10e9.

The override parameter on the densepose repo is to make it compatible with recordings from Pupil Player.

Here you have the barebones, for a simple gaze overlay, maintaining the audio. Note that you will need to change the input path.

@user-a64a96 And so you can also see that the temporal offset occurred because you used the gaze overlay video and not the original. Here you have the circle being plotted using the code above with the original video, stack next to the gaze overlay export(left), you can appreciate the temporal offset.
