Hello! Who can I contact with a question about the technical side of the Pupil Invisible EyeTracker glasses device?

Hi, please tell me ASAP why can't collaborators login to a workspace, when I invite them? "Acces is denied" all the time. Do they have to register with the Email? In this case they cannot access the workspace I share as well.

Hi @user-f43a29 , yes, we still have problems with a few workspaces, but it worked with some of them. I have another question. Could you please advise how the QR codes can be recognised, when they are lit up? I was hoping to solve the problem in dark environment, but they are not recognised by the system. Can I try darkening the video and how? Is there a solution? As you can see the not lit up QRs are found sometimes (green in the left upper corner) but the lit up are not.

Thank you @user-f43a29 ! What if the lamps are positioned higher than that and at a bigger angle, so that the QR codes are fully lit up from their front? Do you think that might work? Otherwise I have to ensure that it is bright enough in the room, so that the normal QR codes can be clearly seen. I don't think that it will be that easy to display the AprilTags on the monitor display.

Great, I will try it and will let you know. Thanks a lot.

Hello! I wanted to ask in which format the eye video is recorded and then saved on the cloud since I could only find informations regarding the scene video for which your description states mp4. Thank you very much!

Hi @user-61e6c1, can I clarify with you if you want access to the eye video data?

Invisible's eye video is only available offline. You'll need to access them using Pupil Player, and enabling the eye video exporter plugin. Exported eye videos are in .mp4 format.

Hi @user-07e923 thank you for your message! My question was regarding to a Datamanemant plan I'm actually preparing for our project. I have to declare where and how our data will be stored. For the scene video I think I'm in page. But I didn't really understand how it's working for the eye video. So my question is in which format the eye video gets stored on the cloud?

Thank you so much @user-07e923 but the scene video is stored in mp4, right? And then I've got another question regarding the companion app: As I understood the data gets transferred to the cloud simultaneously as collected, right? So am I suggesting right, that on the companion the data is stored just locally or will it remain there too?

Ok, now I got it! Thanl you very much for your quick help @user-07e923

@user-61e6c1 Just to add on top of my colleague response, data is not transferred simultaneously to Cloud but rather uploaded after the fact (assuming internet connection is available).

I there! I am having some problems with the upload to the pupil cloud. i am using the pupil invisible. The phone attached to the pupil states that the upload has been completed, however in the cloud it states that the upload has failed. Now I am able to export the recording via the phone through a USB cable. However, it is now not in the cloud and when I am uploading to pupil player it doesn't show the fixation point. What could be the problem of the uploading error and if it occurs, how can I make sure I still now where the person wearing the glasses is focussing on?

Thank you Miguel! But the upload is done nevertheless automatically if connected to the internet?

Hi, what is the optimal size of the April Tags for monitors, which are approx. 1,30 far from the eyes? 12 cm x 12 cm or more?

Hi, I´m using pupil invisible and have a question about Pupil Cloud. I have been invited several times to different workspaces so that I can edit recordings. I have accepted the invitations, but only one workspace is displayed. What could be the problem? Is it only possible to accept one invitation? Whenever I accept the invitation, i get the following message: "Unable to accept invitation This workspace invitation has already been accepted or has expired." i have to join the other workspace to work on the recordings.

Hi @user-75e0ea , invitiations to muliple workspaces are allowed. To be sure, the email that was invited and the email that you use to log into Pupil Cloud are the same?

And when you click on the arrow next to the current workspace name, you only see your personal workspace and the demo workspace in the list?

i can see my personal, the demo and one more. but there should be more than three.

Ok, how old are the invitations?

Ok, are you comfortable with sending an email to info@pupil-labs.com from the same email address that you use to access Pupil Cloud? I would then follow-up with an invitation to a test workspace.

Hi, I have a major problem, that some of the students cannot see the workspace, though they have already registered and verified the mail. Please tell me ASAP what they have to do, because it has been more than 2 hours now since they can't work.

how to trim the video on pupil cloud

can we do Reference image mapper with Invisible?

Hi @user-2b5543. Yes, you can. Check out this section of the docs

hey there! i tried that i marked the beginning and end of video and i selected in the temporal selections but its not changing anything

Well, based on that screenshot, you are using recording.begin and recording.end as the events for start and end, which will essentially take the whole recording. What happens if you select indor.begin as the start? Regarding your other recording.end event, try not to use the same name for the events.

i want to know if we can do the same like Pupil core player trimimming the video with the slider bar and exporting and getting the updated CSV files

i tried renaming but its, its not reflecting on the temporal selection to trim the video

so you mean we cannot trim the video at go signal manually and export it and get fresh exports ?

Hi there, I am having an issue where when I attempt to download my recordings in pupil player format from pupil cloud, only the mp4 file downloads and I am unable to open it in pupil player. And I am able to view gaze positions in the browser, but they do not download with the data. Does anyone know what might be the problem?

Hi @user-ed2612! Did you select the Pupil Player format download option? This is the folder you need to get from Cloud to be able to load the recording on Pupil Player. Once downloaded, it should be a zip folder. Could you clarify which files do you see when unzipping the folder?

Which browser and OS are you using? For unzipping, we recommend 7-zip. Which software are you using for unzipping?

Hello! Has anyone conducted research with videos or films using Pupil Invisible? How, in this case, is enrichment loaded and how to analyze these videos further? Because in the enrichment -> reference image mapper it is possible to load only the image reference, but there is no option to load video reference...

Hi @user-66797d , following up on your question (https://discord.com/channels/285728493612957698/285728493612957698/1243253128862634074), maybe give a different browser a try. It also sounds like your network connection could be unstable, so trying a different network connection is also worth a test. You can visit our speedtest to see if you have a poor connection with our servers.

Good evening! I'm sorry to bother you again but I was trying to follow the instruction you send me and I got this mistake "self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: no display name and no $DISPLAY environment variable" while downloading pl-dynamic-rim. Have you ever encountered the same mistake? If you can help me, I will be really grateful. Thanks in advance!

Hi @user-a3c8db , how have you installed Python? What Operating System are you using?

I have installed Python from the official site and I'm using Linux, ubuntu.

Hi guys, lately i have this problem that while invisible companion shows that i record the scene video and capture eye movements, after ending the recording via my automatized python script, it does not contain any information. The recording seems to be connected to by script (kind of as it stops aftre the expected time) but contains no scene video, no event data. And no data whatsoever. However i dont get a error-message or anything. Not at the software(script) nor hardware. The only thing i did encounter was that the mobile and glasses get incredibly hot at times. Even the mobile sends a message of danger that it is overheating. Howeve rit doesnt happen all the time ( i think. I cant check the recording and app during the experiment i use the glasse sfor al lthe time). I am not sure if its connected at all. Is it a hardware issue?

Also it does not happen all the time with the empty recording. Just occasionally.

Yes, I'm using Ubuntu 20.04 running within Windows Subsystem for Linux.

I use 'Reference Image Mapper' to map gaze from video to one image, but after that the timestamp in gaze.csv is changed, could you tell me why? In theory, it should be the same, right?

Yes, it is from enrichment. For example, the original gaze.csv (without mapper, from video and not in the enrichment) has 152356 rows, after mapper, the gaze.csv out from the enrichment only include 147964 rows. 4379 rows lost. Could you tell me how the 30 fps sampling cause the 4379 rows lost?

Hi @user-cc9ad6 ! That should not be the case, could you create a 🛟 troubleshooting ticket, and privately share the gaze.csv files or send them by email to ||data@pupil-labs.com ||, such that we can further investigate it?

Thanks for your reply. As the file is too big, I can't upload it to the private channel. Instead, I send it to the email. Looking forward to your feedback:)

Hi all! I love the interface at the pupil cloud, the quality of the videos is great and the fixation patterns (the small blue rounds) are very interesting and insightful. I was wondering if it is possible to download the videos as such? As I don't own the pupil cloud myself I have to delete my recordings afterwards but I feel it would be a waste if I can't access these great videos anymore. The quality of pupil player for instance is way less.

Hi @user-df855f 👋 ! You can download them using the video renderer which would allow you to trim them, plot fixations, or tune the gaze circle color and size.
