csv file is directly what I want, But I couldn't find the gaze/fixa data on the reference image. According to the output, it seems only export data on scanning video and original video(main gaze video)

@user-cc9ad6 which folder did you download? If you download the enrichment data Nimat (right panel on your Downloads view), you should be able to get the data you need

Hi, do you know why sometimes we can't calibration ? As you can see, the 'Adjust' button is gray.

Hi @user-cc9ad6, can you please clarify if the glasses are connected and if the scene and eye cameras stream fine?

Hi, I was trying to run the code at https://github.com/pupil-labs/real-time-blink-detection/ on my recording with the pupil invisible, since the documentation said that it's working for both invisible and neon. However the code doesn't run, there is any possible modification that I can do to solve this problem? Waiting for your answer, thank you a lot

Hi, I am using the pupil invisible glasses for a study, and in the invisible companion app, I am able to see the eye movements and gaze with the red circle, but when the data is exported to a computer, the red circle is not there anymore. Instead the eye gaze is exported in 2 different files. I was wondering if there is a way to go about exporting the real world recording with the red circle (the gaze)? Also, I have downloaded the pupil player and other plugins, but I am not able to view any of the recordings on the pupil player. I would love some clarifications, thank you in advance!

Hi, I draw AOI places after using Reference Image Mapper, And now I want to find the pixel position of the AOI areas,But it seems that the cloud don't offer that service?

Hi! I’m having issues logging into my pupil cloud account. Everything was working well while I was logged in. After logging out to check another workspace, I'm unable to log into either of them. I don't receive any error messages. When I click the login button, the box refreshes, but nothing happens. I tried resetting my password but as I enter my email I get the message “unable to send the email”. Is there a maintenance going on? Or is it just me?

Hi @user-cc9ad6! I will pass the feedback, there is a way to obtain the mask as a base64 encoded image using the Cloud API but it is a bit uneasy as you will get then some sort of binary mask.

This will be the endpoint. /workspaces/{workspace_id}/projects/{project_id}/enrichments/{enrichment_id}/aois/{aoi_id} if you are unfamiliar with the API and not too keen on programming, I would recommend looking at our custom consultancy options

Thank you for the update! I exported the videos from the app, but I am still not able to view them on pupil player. Unfortunately for privacy purposes and the nature of the study, I am not able to upload the data to pupil cloud.

thank you for this! what's a good email I can invite you or miguel with?

Hi, I am new to pupil labs and want to figure out how to use the demo videos for practice before I work with actual videos recorded through the device. When I open the cloud and try to add an event (so I can experiment with enrichments) it says "disabled by permissions". Is this normal?

it would say no recordings found. I'm trying to upload the mp4 files

Hi @user-b9d000 ! That is normal, the demo workspace is available to everyone, so we disable certain functions to prevent this demo from becoming a mess. You should be able to create events in your recordings.

No, there is no way to do so 😓 . May I ask what you are missing/want to explore that is not currently in the demo space?

HI! I would like to know the uncertainty with which the duration of each fixation is estimated. where can it be found? Thanks !

Hi @user-c07f5f ! There are no uncertainty values for the duration of fixations, you can read about the algorithm employed here and even modified it if you need it.

thanks!

I have and it's still not working. Is there anyone I can call to help troubleshoot this?

Hey @user-b9d000 👋. So, while the demo workspace isn't user-editable, it does demonstrate a lot of Cloud's capabilities in terms of data logistics, aggregate analyses, and so on. Our aim with this was to showcase what's possible and enable people to replicate it using their own eye trackers and studies. Invisible is fairly easy to use, so I'd definitely recommend making some test recordings with it and experimenting 🙂

Hi Neil, I am physically not able to upload or even drag the files or folder into pupil player. Even after I have tried saving the folder to desktop, it is still not letting me upload it on there.

Hi Neil, I am physically not able to upload or even drag the files or folder into pupil player. Even after I have tried saving the folder to desktop, it is still not letting me upload it on there, that's my main issue. But the pupil player log is saying this in the attached image.

Hi, could you please recommend me other device than Anker PowerExpand to be able to charge the Pupil Companion through a powerbank while running the gaze measurement with Pupil Invisible?

Hi, when I create a reference image using a scan and an image, can I use it for different videos in the pl-dynamic-rim (taken at the same spot)? Also, when I download the data for the enrichment, I get a gaze.csv file. Which gaze does it refer to? Because it only contains the scanning video, which has no gaze in it.

Hi @user-b9d000 ! Could you develop what you mean with not being permitted? Do you have Cloud upload enabled in the companion app settings?

Recordings can only be uploaded from the Companion Device. If your collaborator has it on the Cloud, they can invite you to your workspace.

Hi Guys, I need to re-install Invisible Companion in one of the devices. It doesn't appear in Google Store any more. I tried to download it from the link on the website, and it says that the Android version is not compatible. The version on the device is 13. It was working fine before. Could you tell me how to install it again? Many thanks,

Hi @user-1e8b04 👋 ! The Invisible app is optimized to only work with certain Android versions. If the device is on version 13, then it needs to rolled back to an older Android version. Check our instructions for rolling back the device and then try the Google Play Store link again and let us know if that has cleared things up.

Hi! I'm using Pupil Invisible for a research and I need to find the heatmaps, but in the Pupil Cloud when I run the Reference Image Mapper enrichment, it seems to start but then the percentual of the process remains at 0%, even after 2 hours. I think I do everything is necessary, I choose the video, the reference image, the start and end events. Is there something that I could do?

Hi @user-72baa8 👋 !

First of all, could you do some hard refresh of the tab? Some web browsers aggressively put some tabs to sleep and you don't get them updated. If after that it is still at 0%, there are few things to consider.

The time it takes an enrichment to process depends on the length and amount of recordings that are going to be enriched and the queue of enrichments at that are being running at the moment. I.e if many people submit jobs they go on a queue and they will be process as soon as there is processing power available.

If after refreshing the webpage and waiting some time, seems to be still stuck, please reach us with the enrichment ID and we will check it. The id can be found in the enrichment view clicking on the 3 dots next the enrichment name.

6ca9bdac-cd64-4322-b927-aec686ff2cdc This is an other one of 20 seconds with more fixations, maybe it is more complete if you want to check this one

Is this hub going to do the job for Pupil Invisible, so that the companion can be loaded by a powerbank while recording with Invisible?

Hey @user-3c26e4! We can't say for sure that it'd work. Not sure if you've seen this already, but we have a link to one that we already tested in our docs: https://docs.pupil-labs.com/invisible/hardware/using-a-usb-hub/#using-a-usb-c-hub

Hi, sorry to write again, this is the ID of one enrichment with Reference Image Mapper I'm trying to process but it's not working (it's always at 0%), could you tell me if there is something wrong in the recording video or in the reference image? 63f99dbd-c658-479b-9114-3c579ebd077d Thank you

Hi @user-72baa8 ! You need at least 2 videos in your project to be able to perform a successful reference image mapper.

These enrichments seem to have failed quite early. Would you mind inviting me to your workspace so that I can check the videos and give you more feedback on why they might have failed?

Yes of course, do you mean two videos of the same environment of the reference image? How can I invite you in the workspace? I mean with which name?

But how can I insert a regular video inside the pupil cloud? Because I tried but I couldn't. Do I need to do that always with the app Pupil Invisible Companion?

I sent you the invite.

Yes now they show the "error warning" but only after I closed Pupil Cloud, before they were just loading at 0%. Ssorry if I ask you but then I don't really understand the difference between the scanning recording and the regular one, if they are both taken with the glasses, are they not both scanning videos?

Hi, besides your website, do you offer any workshops or classes to teach how to use eye tracker?

Hi, have a problem with recording. The app stops recording with an anouncement "Sensor Failure. The Intertial Measurement Unit has stopped providing data." It happens on 12-20 seconds. When Invisible is connected with a phone the monitor is twinkling. So, it doesnt work at all. I havent used it for several months, and was asked to renew program. Could it be the reason? or what I should do?

Hi @user-35fbd7 ! Could you please write to [email removed] such that we can follow up with some debugging/troubleshooting steps?

Hi, I have a major problem with the automatically generated screenshot in Pupil Cloud, onto which I'm defining the areas of interest. This screenshot is made only at the beginning of the video while driving a bicycle. For the first event section this is okay. In the same video I'm having another event section starting from the middle of the whole video and there I want to define another areas of interest according to the different view. Unfortunately a screenshot appears from the beginning of the video, though I put the new start and end of the event. This doesn't make sense, because I cannot define the areas of interest according to the new view. How can this be done? If this is not possible, then I would advise you to program it, because it's a very important thing for research. Thanks for your answer in advance.

Hi @user-3c26e4 ! Are you using the reference image mapper?

I guess, if you are not using the Reference Image Mapper, then you are using the Marker Mapper,~~ but I doubt you used markers while riding on the bike. Is that the case? ~~

Just to be sure we are on the same page, to define Areas of Interest in the Cloud, you currently need to either use the reference image mapper enrichment or the marker mapper.

Both enrichment or analysis tools serve to remap the gaze from the scene camera onto a picture or surface (i.e. a 2D space). The difference is that one requires you to use AprilTag markers (some sort of QR codes), and the other one needs you to scan the environment and provide a picture.

In the case of the Marker Mapper, the image is selected from the content within the surface (as defined using the markers) in between the start and end events. For the Reference Image Mapper, you provide the image.

Hi, I just insert the lenses, and on the first recording, this message showed up. "Recording error We have detected an error during recording! The second message is a pop-up window titled "Sensor failure" and reads: The Inertial Measurement Unit has stopped providing data. Please stop recording. Unplug the USB from your Pupil Invisible Glasses and then plug it back in. If this behavior persists, it may indicate a Glasses or Companion Device issue. Reach out to our support team for help." Can you assist with it, please?

Hi! I'm interested in using the face mapper enrichment in research. What we want to do is determine where on the face an individual is looking, for how long, etc. and compare this across participants. I have two questions: 1) It seems the best way to do this would be to compare fixation coordinates with the coordinates of the face features (e.g., left eye, right eye) and see when they match. Just wanted to check that this is the best way to do this and I'm not missing some kind of data that actually tells you where on the face an individual is fixating. 2) In the face_detections readout, it lists the coordinates of facial features as they change in real time. I was wondering about the temporal granularity of these coordinate changes -- basically, what triggers the recording of a new set of coordinates for the features? Is it when the x and y coordinates of the bounding box rectangle change?

Hello Pupil Labs, we have finished collecting data and are working on trying to analyze it but have a couple questions:

• We recorded data with Pupil Invisible and are performing gaze correction outside of Pupil Cloud. Is there any way we can bring these videos back into Cloud for analysis? If not, is there any way to apply gaze correction so that we can use Cloud?
• We want to track a person as an area of interest. This person is different from video to video and we did not collect a scanning video of any person to use the reference image mapper. Is there any way to extend the face mapper to also include the body of the person? If not, is there another way recommended to track whether the gaze is looking at a whole person?

Hey there, I'm having trouble downloading scene videos from pupil cloud. The videos display properly on the browser, but when I attempt to download the scene video, no video file is dowloaded. Does someone know what might be the issue?

Hi @user-ed2612 👋 ! Which browser are you using? And which download link are you clicking on when that happens?

Hello, when we've been using the glasses after 1-6minutes the phone will vibrate and we'll get this error message and the recording stops (it won't continue recording) and won't save

Hello Pupil Labs, your answers have been immensely helpful. Can we run reference image mapper or something similar on Python? It seems this tutorial exists (https://docs.pupil-labs.com/alpha-lab/gaze-metrics-in-aois/) but it requires us to use Pupil Cloud’s Reference Image Mapper beforehand which we cannot do because we have been correcting the gaze in Pupil Player. Is there any way we can use the reference image mapper outside of Cloud?

In addition, because we are using Pupil Player to correct videos saved in Pupil Cloud, we were wondering if the fixations automatically calculated in Cloud will also be transferred to Player and corrected. I am aware that Pupil Player does not do fixations for Invisible, which is why it would be great if there was a way to preserve the enrichments/corrections to the fixations computed by Cloud even after moving it to Pupil Player (is merging the fixation dataframe in Python a viable option prior to gaze correction?)

Hi all. I ran a study that calculated a very high average fixation duration (~1500 milliseconds) for several participants using Invisible. Is it possible for you to take a look at some of our data recordings and see if the tracker failed?

hi... the enrichment I've just created has been running for 1hr...is it normal?

hi... the enrichment I've just created

Does anyone know if the blinks detected by pupils lab count winks? would a blink only be a blink if both eyes are closed? what if they close one eye only (tic r something)

Hi! I'm using the realtime API to stream video from the scene camera, and I've noticed that some frames have a poor quality (see picture). I would guess it has something to do with the encoding, but I didn't find much documentation on this. Any advice would be greatly appreciated 😀

We work with children and we noticed that some of our young kiddos (4yo) partially close their eyes or blink quite often but not both their eyes and we were wondering if those one-eye blinks would change anything.

Hey Neil, i was wondering if there is also an academic price for the invisible Glasses. Just found the regular price of € 4750. Im a psychology Master Student and would like to buy (or rent?) these for our research? Thanks in advance.

Hi @user-fbac90! Unfortunately, the price you saw was a bug on our website. It has been fixed to reflect the correct price of Pupil Invisible which is € 5900 (€ 5200 with the academic discount). Apologies for that!

Please bear in mind that we are discontinuing Pupil Invisible. We would highly recommend Neon instead since it offers improvements in accuracy, modularity, provided metrics, scene camera field of view and more (please have a look at the comparison table). Note that the cost difference is only 50 EUR between the two!

If you'd like to see both products in action, feel free to DM me or send us a mail to info@pupil-labs.com and we can schedule a Demo and Q&A session via video call 🙂

Hi Pupil Labs!

I am trying to get real time IMU data from the glasses. I used to do it using the ndsi lib but now that is not working. The new real time API seems to have a dedicated funcion for this but is blocking and not working either.

I've read in a post by Marc that the new companion version for the smart phone will support the streaming of IMU data in real time. Is that so? Is it possible to know a date for the release of that new phone app supporting real time IMU data streaming?

cheers, Tomás.
