Hello,

Im trying to run recv_message.m on matlab. I opened pupil capture on the side and downloaded the two folder packages "msgpac" and "zmq" and placed them on my desktop. However, whenever I run the code, I receive an error that that "undefined function or variable 'socket'" Can anyone help me out with this?

Hello,
if i use recv_world_video_frames.py as it is i get

topic,msg = sub.recv()
ValueError: too many values to unpack (expected 2)

if i split the line to look like

topic = sub.recv_string()
msg = sub.recv()

creating the image ends with

img = np.frombuffer(msg['__raw_data__'][0]).reshape(720,1280,3)
TypeError: byte indices must be integers or slices, not str

i tried

img = np.frombuffer(msgpack.loads(msg)['__raw_data__'][0]).reshape(720,1280,3)

which tells me that there's a key error with 'raw_data'
am i missing something here?
Best regards
M

Hi, I have organized a repository with stuff that may be useful for talking to pupil from free pascal. It includes a class for applications (Pupil Client) and a no gui example (Pupil Tasks):
https://github.com/cpicanco/pupil-fpc-examples

See /examples/pupil_client.pas and /examples/pupil_task.pas.

If you do not want all examples (and all dependencies) you can use https://github.com/cpicanco/pupil-fpc instead.

This more a question than an issue.

I am using the pupil_sync_complete.py example for one of my projects. But I would like to process the incoming notifications on the main thread since I have some UI stuff to do. In pupil_sync_complete.py, l.328 notify_all() is called in the background thread. This is undesirable for me.

Is there an easy way to call this function on the main thread?
If not: My idea was to send it back using the pipe and manually checking self.thread_pipe for POLLIN events in the main thread. This way I have to manipulate the original code. Is there a way to implement this by subclassing Pupil_Sync_Node and not rewriting the complete _thread_loop() method?

Make a branch for pupil-helpers python3 compatibility.

The message pattern has changed. We should now subscribe to surface and use the norm_pos from ['gaze_on_surface']

Overview

Bindings for pupil-helpers that are written in languages other than Python will be linked in the pupil-helpers readme.

PRs to pupil-helpers repo should be revisions of the existing python pupil-helpers examples or new concise example scripts written in Python.

Actions

1. Update readme with contribution section outlining the scope of contributions (as noted above)
2. Update readme with bindings section with links to bindings contributed by the community.

Hello,
I would like to use Matlab to get Online Fixation data in the Pupil Capture, what parts should I modify in the code.

I tried to change gaze in filter_messages.m to fixation, but I failed

PyUserInput is out of work, according to https://github.com/PyUserInput/PyUserInput.
It would be good to make the changes for the mouse control to work with pynput.

Hi there,
I followed the steps in "readme" and everything seemed to be ok but when I tried to run the file, matlab just crashed...

System info:
Windows 10 64
matlab 2019a
ZeroMQ: 4.3.2
PupilCapture: 1.13-29

Thank you

In this example: https://github.com/pupil-labs/pupil-helpers/blob/0df77b47cebd49a6c35b6769da483c115a626836/pupil_remote/recv_world_video_frames.py it uses 'frame.world' for the topic, but the frame that I am getting that seems to correspond to 'frame.world' is 'frame'. This means I have to subscribe to both eye frame feeds in order to get the world frame that I would like.

Hi,
does anybody know if /pupil_remote/filter_gaze_on_surface.py script can be optimized for realtime application. I need to capture in real time user's gaze positions and open/close windows using PyQT

Hello!

I'm getting following error, running pupil_remote_control.m:

Undefined function or variable 'req_socket'.

Error in pupil_remote_control (line 21)
zmq.core.setsockopt(req_socket, 'ZMQ_RCVTIMEO', 1000);

Looking at the Matlab code, i see that the variable 'req_socket' is not defined before. Is this an issue and if, is there an workaround?

best regards!

Hello,

I would like to apply the code "mouse_control.py" of the Pupil Capture for the Pupil Invisible. What should I change in the code to use that for the Pupil Invisible ?

Thanks.
