Hello, I have always used Pupil Cloud for my Invisible until now. I am experiencing storage space issues. Would it be possible to analyze the data using Pupil Player? When I transfer the data to Pupil Player, I receive several error messages. What other options besides the cloud are available to me with my Invisible glasses?
Hi @user-75e0ea ! Yes, absolutely.
In addition to using Pupil Cloud (and just a heads up, you can delete recordings there to free up space), you can also work with Pupil Player.
Just note that the data format differs, and some tools (like Reference Image Mapper) aren’t supported.
What kind of issues are you running into with Pupil Player?
There are three pairs of glasses on my list. I have unlimited storage space for two of them. But not for the third . I only noticed this too late, so I can`t upload the data for the third pair of glasses to the cloud. I need the recordings and do not want to delete it.
What I meant was, that you can process your data in Cloud, download it, and then delete the recordings to free up space. But if you'd prefer not to delete them, that's totally fine too.
That being said, I believe you should be eligible for the EAC, which includes extended Cloud storage until October, so you shouldn't be hitting storage limits yet. Could you email [email removed] with your order ID so we can check that for you?
As for the issues with Pupil Player, it sounds like they're mostly notification-related, but just to confirm, does the recording load successfully? If so, you can ignore them.
If not, could you send over the player.log file from the pupil_player_settings directory, right after attempting to load the recording?
Feel free to attach that in the same email so we can keep everything in one place.
Good afternoon, I have a question towards the pupils invisible cloud application. I am getting close to the storage limit of the cloud and so I exported the data files from the companions app as a backup. If I would delete the videos on the cloud to free up some storage, can I import again these files somehow into the cloud or is that not possible and I have to use for further data analysis the pupil player?
Hi @user-6e6f9f! Reimport of deleted recordings to Pupil Cloud is not possible. You can purchase more storage via an add-on - pricing here. Or else, it's recommended to complete your Cloud analyses before you delete the recordings to free up space. Pupil Player is also an option for basic offline analysis.
Hi @user-f43a29 , I have recorded a data in the mobile. And I have uploaded the same on the cloud from the mobile. but in the cloud, it is is not visible. It is saying - " Cloud Storage Quota surpassed for this device. please purchase an addon". However, i have deleted all my previous recordings. So, I guess the new recordings should now be visible. but they aren't showing up. Could you please guide?
Hi @user-9e276a , they are probably still in the Trash. To fully delete them and free up space, click the three button menu next to Add filter in the top left and choose Show trashed. Please note that this will permanently delete them from Pupil Cloud and re-uploading is not a supported workflow, so be sure to make a local backup, if you will need them again at a later date.
I understand that you do not want to provide the yaw or quaternion values because it is drift prone. In my specific context, drift is not a big issue, so i would like to know if you could provide "the IMU coordinate system and positioning of the IMU within the invisible headset" (https://github.com/pupil-labs/pupil/blob/7a3cd9e8d2e54ac123ab0ed292d741732db899a2/pupil_src/shared_modules/imu_timeline.py#L571 l.204-205) for the yaw component so that I can compute it myself ?
Hi @user-e0a93f 👋. It's not really that we don't want to provide the yaw or quaternion values. But rather, without a reference to heading (e.g. magnetic north) the fusion algorithm cannot compute it. Nonetheless, the raw gyro data is exposed, so you can indeed try to compute it yourself. You can find a description and diagram of the IMU coordinate system and positioning within the Invisible headset in this section of the docs: https://docs.pupil-labs.com/invisible/data-collection/data-streams/#inertial-measurements
Thank you very much for this answer 🙂 The figure helps a lot. I will just assume that the initial frame is the zero heading.
A quick a note, this is a very well established challenge in inertial odometry. If you're planning to integrate the gryo readings to compute position, the drift is exponential. You can of course try it to satisfy your curiosity. But if a hard requirement of your use case is absolute yaw orientation, you'll need to find another reference source. Depending on the task, the Head Pose Tracker plugin in Pupil Player is one option.
Thank you for the usual quick and accurate answers to our questions, so refreshing ! You guys are killing it, keep up the good work 😉
How do I tell Pupil Cloud to estimate the pupil diameter from my pupil invisible glasses? Does the pupil estimation require a paid subscription to start processing? I have an account, but I think it is free. Or must I use the account of the e-mail address of the person who originally bought the glasses (I have them on loan)? Thanks
It might be due to not being able to read the serial number?
Hi @user-56c45f. The Invisible glasses do not measure pupil size, which is why those measurements aren't available in Cloud. This is because Invisible's eye cameras are orientated such that they don't have a clear view of the pupil. It was not possible to do pupillometry reliably.
Ok, thank you for confirming! I get that the system main plus is that you can walk around with it on the street, and looks and feel like actual normal glasses. I think that works really well.
No problem. Yes, that's one of the strengths of Invisible's approach: measuring gaze data in demanding environments.
