Hi Sophia, You're probably hearing a kind of crackling noise, right? That happens when the buffer is too small. If you increase the sound buffer size (under back-end settings), the problem should go away. (Quote) Yes, PyGaze is used by the sampler…

(Quote) You mean that the overview area doesn't scroll during drag'n'drop? That's true, although I'm not sure why it would ever have been different. (This is a property of the UI toolkit, not something that I explicitly implemented.) What you could…
-
(Quote) Yes, absolutely! What I would do is create a few bitmaps with noise textures, and use these in the experiment. Will that do as well? (Quote) The sketchpad does this automatically. (And, in any case, it's not applicable here because you're n…

Hi Noa, There are a few separate things here: (Quote) Different EyeLink calibration routines are all just different layers on top of the same system. So it doesn't matter if you calibrate with PyGaze/ OpenSesame, or using another tool. What is the…

Hi Daniele, It would be helpful if you upload: * The experimental script; and * The data file. And also an explanation of how we can tell from the data file that something went wrong. (Quote) Right, that would be my first thought as well. Where …

Hi Laurent, Good to see you back on the forum! In general, the most common cause for these excessive preparation delays is when you: * draw many elements to a canvas object; and * you don't specify auto_prepare=False; and * you use the expyriment…

Ow right, I got my milestones mixed up. The fix will indeed be included in 3.1.5!

Here's a simple script that parse the datafile and plots it as a figure, or rather two separate figures, one for the x coordinate and one for the y coordinate: import jsonfrom matplotlib import pyplot as pltSRC = 'data.json'# Read the datafile as t…

Hi Isaac, The logger uses utf-8 encoding as well. Are you sure that you didn't simply open the logfile with the wrong encoding? Many programs try to autodetect the encoding, or simply use the operating system's default, which for Windows isn't utf…

Good to hear that you got things working! B)

Hi, This is a bug with Mac OS line endings. It's already fixed in datamatrix 0.3.2, a sub-package of OpenSesame, but not included in the latest release of OpenSesame. You can update datamatrix by entering the following the debug window (on two sepa…

@moreno (Quote) Yes, but you have to install it manually (i.e. not through pip install): * https://github.com/dschreij/opensesame_soundrecorder_plugins/releases

Fyi. Here's a very similar discussion, but the reported jitter is much worse—too much to be accounted for by using time.time(): * http://forum.cogsci.nl/index.php?p=/discussion/2581/

Hi Guido, This is puzzling indeed. There's threading involved, which always introduces some jitter. But this seems a bit much, even for Python threading. Here's what I would try: for i in range(10): eyetracker.log('T%d = %s' % (i, clock.ti…
-
(Quote) It's an explanation, yes. Line breaks are encoded differently on different platforms. OpenSesame should compensate for this through a conversion, but this conversion appears to be bypassed when pasting directly into a text field. That's a bu…
-
Hi Guido, You'll have to be a bit more specific. I can see in the experiment that you have a 3000 ms delay between calling eyetracker.start_recording() and eyetracker.stop_recording(), at least if display_offset is 3000 and post_view is 0. So I get…

@Veronica Do you sometimes copy-paste text into OpenSesame? For example that you prepare some text in a text editor, and then paste it into OpenSesame? @oriane_g26 Please post a note in the other discussion with some more details, including your op…

Hi guys, Here's a few thoughts. And @tsummer2: Congrats on doing such careful testing! Few people bother to do that. (Image) Let me first point out that the sampling rate of the EyeTribe is (at least by default in the non-pro model) 30 Hz, or on…
-
@Veronica I attached the fixed version. Essentially you can extract the file pool and script with a tool like 7zip, and then edit the script, as described here: * http://osdoc.cogsci.nl/3.1/dev/fileformat/ The error has something to do with the ty…

@oriane_g26 Are you having the issue described here? * http://forum.cogsci.nl/index.php?p=/discussion/2437/ If so, let's continue the discussion there.

Hi Veronica, You can manually edit the experiment script in a text editor to fix the issue, and the re-open it in OpenSesame. If you attach the file to this post we could take a look. So that will be fine. The important question, however, is how t…

(Quote) This may be my atheist background showing through, but I actually had to look that up. It was also pakjesavond though. (Quote) Possibly, yes. But it may also be related to the keyboard. Keyboards also poll periodically, although typically f…

Hi, This script took me a while to wrap my head around. (Image) But I think I got it now, at least well enough to answer your questions: (Quote) You're flushing the key buffer (kb.flush()) after collecting a response. There's no need to do that…
-
(Quote) Yes, that's correct. I should say that opinions are divided about whether drift correction is useful in these kinds of set-ups. I think that drift correction was originally designed by SR Research to deal with their helmet-based eye tracker…

@jtpar Could you check whether (or confirm that) this issue still exists in 3.1.4?
-
Hi, I haven't seen this error before. Which version of OpenSesame are you using? And which version of the Eye Tribe software? If either of them is not the most recent, I would first update to see if this resolves the issue. Cheers! Sebastiaan

Hi Guido, Could you upload your experiment and the datafile? Cheers, Sebastiaan

Hi Karin, The discussion that you're referring to is quite outdated. Nowadays pseudorandomization is implemented in the loop item: * http://osdoc.cogsci.nl/3.1/manual/structure/loop/#pseudorandomization I hope that gets you started! Cheers, Seba…

Hi Sarmad, I think we should probably take a step back. Yes, there are, of course, other and better approaches to detect eye blinks than just looking at zeros. But I have the impression that you have very little experience working with this kind of…
