@_elena_ Thanks, this is very useful 👍️ We'll include that fix in the next maintenance release of PyGaze.
-
@MicolG I would indeed recommend using another laptop. In theory, you might be able to resolve this by updating the operating system/ video drivers, but that's not guaranteed to work and in any case it's probably more trouble than it's worth.

Hi @elena , However, the experiment keeps lagging with my gaze contingency inline_script and runs correctly when I remove it (maybe the problem is due to if statements and while loops to be executed) . (…) The experiment runs and finishes correctly …

Hi @naltvat , It sounds like you've been running into a series of issues that, or at least I suspect so, are unrelated to each other. (Which doesn't make them less annoying, of course.) I'm not sure what you tried so far, but my recommendation would…
-
Hi @S_H , I'm happy to be corrected / updated by someone who has more experience with this than I do! But my guess is that not much has changed in how this is usually done: The loudness of the response is determined, for example by taking the root-m…

Hi @MicolG , @kri is correct about this: this message indicates that the browser doesn't support WebGL, or at least not in the way required by pixi.js, which is the graphics library used by OSWeb. (If the get.webgl.org website indicates that WebGL i…
-
Hi @_elena_ , It's still difficult to tackle this, because I don't experience the issues myself. (Although I do experience the slowness, which is annoying.) What version of the OpenGaze SDK are you using? The latest version at the time of writing is…
-
Hi @naltvat , This is due to the fact that OpenSesame 3.2.8 is quite old and comes with an outdated version of the media_player_mpy plugin. Updating the plug-in to the latest version (right now 0.1.11) should fix this particular issue. But more gen…
-
Hi @ClaudiaS13 , Can you try to explain again exactly what you want to do? Because right now that's not very clear to me. From the perspective of the participant, what does the trial look like, and what is the task? And from the perspective of the r…
-
Hi @Jordan , I'm assuming that you would like OpenSesame to control the flow of the experiment, and then present stimuli in a virtual environment controlled by Unity. Is that correct? That would be very sweet. I have never worked with Unity myself, …
-
@_elena_ Thanks. It seems that the xml string contains two messages, rather than one, probably because they haven't been properly split. I think that's easy to fix, but again you'll have to test this for me because I don't experience this myself (m…
-
Hi @_elena_ , Thanks for reporting this! We've done quite a bit of work on improving support for the GazePoint, but it's still pretty rocky. As a first step, let's try to figure out where this error comes from. If you open C:\Program Files (x86)\Ope…
-
Hi @zoe_e , This error usually indicates that the file is corrupted, or at least that it's not a valid .osexp file. However, without seeing the file it's difficult to say for sure. Could you attach the experiment file here? Alternatively, I was won…
-
Hi @mfp49 , The first step would be to clarify what your set-up looks like and how the different parts are connected. You mention a 'trigger box'. What kind of device is that exactly, and what kind of input does it expect? Do you have examples from …
-
Hi @ipekcelik , I am aware of this error message. I don't know where it comes from, but I guess it's a subtle compatibility issue in one of the libraries used by OpenSesame. It's harmless though, so you can ignore it! -- Sebastiaan
-
Hi @kolfers , Thanks for reporting this! I actually don't see this behavior myself on my Windows 11 test system, but my guess is that this is a subtle difference between operating systems. It's easy to see where it comes from though: when a sleep oc…
-
Hi @research_cat_10 , Thanks for bringing this to our attention. There was indeed a bug in OSWeb related to unmatched quotes in text, which happens to affect Hebrew because of it's use of a double quote as a punctuation character. If you update open…
-
Hi @Tbucck , pylsl is not bundled with OpenSeame and thus needs to be installed separately. You can do that by typing the following in the console: !pip install pylsl See also: https://rapunzel.cogsci.nl/manual/environment/ Good luck! — Sebastiaan
-
Hi @Pieter_ , I still don't know where this error comes from, but since it seems harmless I made a small update that catches it. Could you confirm that the error is gone when you update to OSWeb extension 1.4.13.1? conda update opensesame-extension-…
-
Hi @Pieter_ , When testing an OSWeb experiment, the .osexp experiment is first saved to a temporary location, then converted to an .html file so that it can be opened in a browser, and finally the temporary .osexp file is removed again. This last…

Hi @kolfers , I only spotted this discussion now. Did you make any progress on this? In general, you'd need to use the MediaRecorder JavaScript API for this. But I haven't used this myself yet. https://developer.mozilla.org/en-US/docs/Web/API/Media…
-
Hi @hannahl , If memory consumption reaches 70%, then this is almost certainly the cause of the Python crash. You're also using an outdated version of OpenSesame. I don't think that this is the issue, but it's still possible, so I would first update…
-
I'm guessing js2py can't convert random back to python, maybe? Yes, that's correct! See also: https://osdoc.cogsci.nl/3.3/manual/javascript/about/#available-javascript-libraries
-
Hi @kolfers , I would adapt the the wait_for_event() function from PyGaze to break after a timeout. https://github.com/smathot/PyGaze/blob/master/pygaze/_eyetracker/libeyelink.py#L684 I blind-coded the example below (I don't have an eye tracker no…
-
@ethanweed This behavior results from the custom Array.prototype.random() function in the counter_balance script. I don' fully understand how this results in the behavior that it results in, but it certainly has unintended side effects. You can avo…
-
Hi @ethanweed , That's very strange indeed, thanks for pointing this out. I'm going to look into it! — Sebastiaan
-
Hi @Julia@julia_m , In general terms, what seems to happen is that OpenSesame tries to change the way that multiple processes are created by the application, but then crashes because this has already been done, and this is something that an applicat…
-
Hi @MaximeL , You probably have an operation in the script of a loop item that operates on a column (with the name Context) that does not actually exist in the loop table. If you open the script of the loop item and search for 'Context' you should…
-
Hi @Jordan , You cannot disable this in the user interface. However, if you want to implement something like this, for example because you're going to collect a large number of participants and you want to make sure that this is done systematically,…

Hi @Roland , The stimulus sketchpad that precedes the coroutines simply stays on the screen until the first sketchpad in the coroutines overwrites it. This is indeed a somewhat unpredictable duration that includes the preparation time of the ite…
