Would you be able to further elaborate on your use of the network api - are you rendering the video frames + gaze overlay or just streaming the raw gaze coordinates?

Hi - I was trying to run the gaze_contingent_demo in PsychoPy and this is the error I receive:

Traceback (most recent call last): File "C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\utils.py", line 598, in save with open(self.file, "w") as f: PermissionError: [Errno 13] Permission denied: 'C:\Program Files\PsychoPy\psychopy-gaze-contingent-demo-main\README.rst'

hi looking for advice, when subscribing to the surface tracker, it seems to freeze my python code when no surface/gaze on the surface is detected in that moment. However subscribing to "gaze." pushes a msg about the gaze information every frame with no freezing. Even using a try: except when subscribed to 'surface' doesnt prevent the program from hanging.

I assume this is because of how sub.recv_string() and recv_multipart() work, but is there a way to even just get a "surface: none detected" so that the program doesnt hang?

I tried using threading instead to wait for the surface to be detected, but it seemed to run even slower in the thread, and additionally, once the surface was detected, there seemed to be a backlog of messages waiting to get printed, which were definitely not caught up, as it showed i was looking between surfaces 1, 2, 3, and 4, even nearly 20seconds after looking away from any surface.

Is there by any chance an open source github repository that I can view for the Neon Companion Monitor from http://neon.local:8080/

Can you share your code here?

im looking into building a similar monitor app, I have looked at the provided API links and I have managed to create a working video feed, but I was just unsure how to approach connecting it to a UI so that I could control some of the features such as starting/stopping recording with a button and manually adding in events etc.

im currently using imshow to render the image, is it possible to build the UI off of the imshow function?

Ah, yes - recv_string blocks by default. Try this instead:

try:
    topic = sub.recv_string(zmq.NOBLOCK)
    msg = sub.recv
    ... snip ...
except zmq.ZMQError:
    # No surfaces - should probably sleep here
    pass

See: https://pyzmq.readthedocs.io/en/latest/api/zmq.html#zmq.Socket.recv

Hello! Does anyone know if there's a way to get the old Pupil Mobile APK? We need to use a phone for running tracking in our study, but are using a version of the pupil labs for HoloLens system, not Neon, and the app is no longer on the app store.

I'm not sure if it's a good channel, but I may have hit the right one. We are trying to use an image mapper using an implementation in Python. Unfortunately there is no good documentation anywhere on the pupil labs site on how to do this. There is this page: https://docs.pupil-labs.com/alpha-lab/gaze-metrics-in-aois/#define-aois-and-calculate-gaze-metrics But it only shows the implementation for determining the AOI.
What we need for the project is an implementation from scratch, i.e. how to use code to combine a reference image with a movie to convert fixations from a movie to a static image? Because if this would work, then if I understand correctly, then having this, then using the above link to determine the AOI using the reference image?

I would greatly appreciate your help.

Hi everyone, I wanted to create a simple player that streams pupil invisible or neon cameras via rtsp. I wanted a way to test the RTSP streaming. Can I use usual video players (like VLC player) for testing?

The study requires mobility that even a PC backpack may restrict. I know it is no longer available, but is there any way you can provide the old APK for us to sideload? Even if it is no longer supported, we just need to be able to run this off of a pocketable device. I have found links online to the archived APK but the websites are extremely suspicious and I would really prefer not to have to take that route.

Now that there is a local Neon environment, does that get recorded on a phone?

Hi @user-e637bd ! Could you please develop? Neon did always recorded locally on the phone, then you could choose whether to upload the data or not to Pupil Cloud. Have a look about the first steps here: https://docs.pupil-labs.com/neon/data-collection/first-recording/

I was just asking based on the above comment Unfortunately, the APK is no longer available. But you could in theory use a smaller device, like a small-form factor tablet style PC, to make Core more portable.

I just wanted to make sure that the same process for Core exists with Neon, its just a different app, ?

[Pupil Core](https://pupil-labs.com/

Gotcha! My concern is that the site officially lists that the requirements are an intel i7 minimum but portable PCs will run on something like an Atom processor. Have you ever seen Pupil Core run successfully on weaker hardware?

I'm currently conducting an experiment at a commercial facility using the pupil invisible. After capturing data and adding Events on pupil cloud for both the entry and exit times, is there a way to download the Timeseries Data for the duration between these events?

Hi, i'm using pupil invisible and i'm trying to define AOIs in the reference image. I've copied the code in this page https://docs.pupil-labs.com/alpha-lab/gaze-metrics-in-aois/#dependencies-of-this-guide, but when i try to run the programme, this error appear (the code in image is that one which make the error).
