Hi, This seems to happen when gaze stabilization is enabled, while fixation checking is not. The solution would be to explicitly get gaze position at least once regardless of the settings. If you take a look at the part of the code where the error …

Hi Candice, Interesting! It sounds like you have a few options, but the best option depends on what you want to do exactly, and what kind of tablet you want to use. The easiest option is probably to use Windows tablets, so that you can simply use …

Hi both, Thanks for this workaround! I was aware that PyGame (the underlying library) sometimes ignores mouse-position changes, but I don't know exactly why or when this happens either. Cheers, Sebastiaan
-
Hi, As long as you don't explicitly use the mouse, then mouse clicks should have no effect—certainly not crash the experiment! What do you mean exactly? In what sense does the experiment crash, and what kind of error message do you get? Cheers, Se…

Of course, asking on the OpenSesame forum about the quality of OpenSesame will give you mostly positive responses. Maybe you should ask the same question on the DMDX forum and then take the average? :wink: If you find something that appears to be a…

Hi Steve, Under Menu → Tools → Example experiments, you will find a few well-documented examples, including some that use reaction-time measurements. Cheers! Sebastiaan

Great!

To be able to run an experiment on Android, you need to take a few things into account, the most important of which is that you need to select the droid backend (not xpyriment!). For more information, see this page: * http://osdoc.cogsci.nl/3.1/man…

Great to hear that you figured it out!
-
Ah, thanks. @Daniel Is this something we can address for the next release?
-
The file is there, trust me. (Although whether it will contain useful information is another matter.) It's a bit difficult to browse the android file system, but there are several explorer apps in the Play Store that make this easier.
-
Hi Mila, You're very close. I think you only need to replace the practice_stimuli and the following new_keyboard_response (make sure to give items useful names!) by a simple inline_script. In the Prepare tab you would then create a keyboard object…

What does /sdcard/opensesame-debug.txt say? * http://osdoc.cogsci.nl/getting-opensesame/android/#debugging

(Quote) Well, there's also GazePoint, which is somewhat cheap, and should work in PyGaze as well. At least @Edwin committed some code for it. Pupil labs tracker is cheaper though, so it might pay off to buy it and then pay someone to add support fo…

I'm afraid you will have to be more specific! What exactly do you want to do, what have you done so far, and why doesn't this work as expected?
-
As Roelof points out, the behavior of 3.1 is to automatically rename items so that they have a name that is also a valid Python symbol: a string of alphanumeric characters and underscores that does not start with a digit. It sounds like you created…

Hi, Could you post a screenshot to illustrate the issue? Cheers! Sebastiaan

Hi Stephane, @Jarik pointed me toward these two links: * http://itmwiki.psy.vu.nl/index.php/Possible_new_monitors * http://labs.psychologie.uva.nl/labs/tms-labs/tms-labs.html (Quote) Yes, I think that many LCD monitors can handle that just fine. …
-
Hi, That's an interesting concept. I'm guessing that you'd ideally have a continuous sound that smoothly changes in pitch and volume as a function of mouse position. Is that right? If so, then the synth is not going to help you, because it will onl…
-
Good to hear that you managed to get the basic task up and running! It would be best if you attach your experiment to this discussion, so that I can see what you've done so far, and how to best implement the word-by-word presentation.
-
Right, I see. What you can do is use the set_draw_calibration_target() function. This expects a function that takes only (x, y) as function arguments, and then uses this function to draw the calibration target. I see now that PyGaze by default also …
-
Hi Emphyrio, The start time of the video is automatically recorded as time_[name of item]. So, if we assume that your media_player_mpy item is simply called media_player_mpy, then you could determine the response time by inserting a simple inline_s…
-
Hi Luke, In principle , there's nothing wrong with doing: import pylinkpylink.setCalibrationSounds('off', 'off', 'off') Are you using the PyGaze plugins in OpenSesame, or PyGaze directly as a Python library? The pygaze_init plugin in OpenSesame …
-
Hi Mila, Here's my suggestion. First create an experiment with a simpler trial sequence: * Show the full sentence (i.e. all words separated by spaces) * Collect a keyboard response * Show the question * Collect another keyboard response This is q…

Hi Mickey, Based on the rest of your questions, I'm assuming that 'user trajectory' refers to mouse trajectories? I'm afraid that MouseTrap does not work on Android devices, because it isn't bundled with the OpenSesame runtime for Android. So if yo…
-
Hi Maria, It would help if you provide some info about what ACT-R is, how the software works, and in what sense you want to link OpenSesame and ACT-R. In very concrete and simple terms, what exactly do you want to do? To answer your last questions…
-
Hi Dirk, I've heard good things about pupil labs. Maybe you also saw them at ECVP? * https://pupil-labs.com Now that the EyeTribe and SMI are out of the picture, I suspect that this is the cheapest option. @Edwin? Pupil labs is not supported in …
-
That's great! Just to clarify: this functionality is not included with the current latest version of OpenSesame (3.1.9), but it can be installed afterwards by updating PyGaze. Once I'm back in the office I'll take a closer look.
-
This could be anything. As a first step, I would see if the datafile on the EyeLink PC itself (i.e. not the copy that is transferred to the experiment PC) is also corrupt. If it is, then the problem is likely something with the EyeLink recording sof…

Hi Nathacia, Prebuffering is not a generic procedure, but rather something that is done differently for every type of file. For example, to preload an image, you could draw it onto a sketchpad, and to prebuffer a sound sample, you could load it int…
