How do you define surfaces in vr to calculate later in Player. Are there ready prefabs?

Hi @user-c5fb8b I have a follow up question regarding your response to @user-ac0304 question on hololens support. So do you mean that the latest hmd-eyes only support hololens 2 or all support for hololens stopped at hmd v0.62? Thanks

@user-ac3779 The latter is the case.

Oh thank you @papr

Hi everyone!

Regarding the binocular addon for HTC Vive, can I make it work with a HP Reverb? I can design and print my own enclosure and holder if the default one won'

t fit the Reverb's eye cups, I can also solder a new shape illumination LED ring. But the eyepiece FOV is different and I don't know what other modifications I have to make, for example in code.

hi. I am going to work with eye tracker for headset VR... I have a problem. please guide me. I cant see this process that i showed in this picture.

i cant this part. what should i do??

@user-2c8a6d The cameras should be listed in your Device Manager with the given names

Do you mean this??

@user-2c8a6d yes. Checkout the cameras category. If they are in there, the drivers are not yet installed. Simply run Pupil Capture to install them. Afterward, they should appear in the libusbk category

yes there are

would you please tell me which software exactly I should install? I installed Unity, steam vr, sr- runtime 1. Do I need install others?

also I checked pupil lab Git hub and found pupil_v2.6-19-g6344358_windows_x64.msi.rar.

anybody here?

@user-2c8a6d If you are planning on using our Unity plugin, please follow the instructions here: https://github.com/pupil-labs/hmd-eyes/

@papr are you responding to me?

@papr Somehow Mojgan's messages weren't visible to me for a long time, so I was puzzled whom you were responding to. Maybe the same is the case for my messages not appearing? Should I maybe email the questions instead? Here is a repost:Regarding the binocular addon for HTC Vive, can I make it work with a HP Reverb?

Hi, I'm still a newbie. I have Vive HTC add on but I would like to 3D print a "standalone mount" so that I'll be able to use the add-on both with and without the visor. Has anybody already thought about it? Can you point me in the right direction? The reason I need it is this: I find it difficult to calibrate the add-on while wearing the visor when I'm alone without another person to help me (with keyboard keypresses etc..), so the alternate mount would be used to calibrate the add-on.

Hello, we are using a pupil labs eye for our htc vive but the last 2 days we can only see one camera feed (eye1 and not eye2)

we tried a different cable but still got the same issue

Allright folks, I have a recording from HMD eyes that I'm trying to recalibrate offline. I have plenty of experience finessing the pupil fitting process and gaze mapping process. I've added the on-screen references, created a new 3D calibraiton, and made sure the gaze mapping is using this new calibration. No luck!

Are there any known issues about offline gaze mapping using HMD-Eyes?

I should add that gaze confidence is >.9, but it's dismissing 90% of gaze data during calibration, which is surprising. The blue circles are excellent fits (2D pupil mapping, I assume), but the red circle is chaotic (3D pupil mapping, I assume). So, it seems that the breakdown occurs when trying to fit the 3D eye model.

hi. please guide me. i am in process of installing eye tracker on vive headset. i dont understand what should i do? hmd-eyes/VR Getting Started/ Number 8......This sentence: 8. Use the displayed realtime videos of your eyes to make sure they are as centered as possible and in focus.

what is the meaning of (Use the displayed realtime videos of your eyes)???

I just see this picture

Hello @user-6752ca we have just recently had the same step, and the case is that if I understand correctly why this eventually works - the Pupil Capture necessary to run in the background when running the HMD Eyes on the Unity side - the Pupil Capture cannot take over the view you want to be the source of calibration/tracking - if you want the source to be from the AR mode - that would be something in the physical world - the physical marker for the user to be shown in pass-through mode in order to calibrate. In Unity scenario you want to have system focus on the Unity editor window (it has to be the last recently clicked) before you press C for the calibration. That way you should have it eventually working and not having those NaNs on the Pupil Capture console side and that weird prompt for realtime videos. Someone correct me if I am wrong.

I also have my own question to the Creators/Community - where should I look in the Pupil HMD Eyes 1.4 output created with use of DataRecordingDemo - in the folder created above Assets project folder - how do I get into the data, in which files (everything seems to be encrypted), specifically the changes of the pupils diameters?

I found this info https://docs.pupil-labs.com/developer/core/recording-format/#meta-files, but what we want is simply some sort of .csv unencrypted format acceptable for other software

Pupil Player can get this folder and export most data to .csv, however - is there a way to process the above files within Unity and get the .csv without Pupil Player, or to even stream this data? Sorry if this kind of question has been answered before, but we have not found it until now, so we would be very grateful if someone could tell us how to do it if it is doable 🙂

@user-525b2f Thank you.

During a lab experiment, the add-Ons are very heated. There are any problems on an operational programs? If you know any prevention procedure, please advise me kindly.
