Hi, Does the problem also occur with an older version? 3.1.7 did run for quite some and was rather stable. Can you make sure that the problem occurs also with that version? If not, can you file an issue on Github, preferably including a small exam…

Hi, (Quote) Those are items that you can drag in the Opensesame overview area that handle the starting and stopping the the recoding and the logging of the eye data (that is if you choose to send messages or variables to the eyetracker, the actual …

Hi Satrio, I haven't tried it, but if you modify the code in the link above in this way, does it work? # needs to be put in the run phase!!!!import pygamet0 = clock.time()keydown = Falsekeyup = Falsetimeout = 10000 # how long do you want to wait?,…

Ah, good that you sorted it out

Yes, you're right. There are two different task bars, suggesting that there are in fact two different computers. But as already said, it is hard to see how the computers do communicate with each other. Normally, it is done with a parallel port conn…

Hi Sophia, maybe this links helps: https://www.ffmpeg.org/download.html If not you can always try one of the other players: http://osdoc.cogsci.nl/3.1/manual/stimuli/video/ Good luck, Eduard

Hi Artur, If your logger would take the new keyboard_response_items into account, you would have an accuracy of 80% not 90% (given that you have two of those in your sequence). Probably the problem is related to the coroutine? Maybe you have to mov…

Hi Korem, I refuse to think of better ideas if you have a solution that works just fine and doesn't have any other drawbacks than being "ugly" (beauty is in the eyes of the beholder...) Eduard

Hi, Unfortunately, I don't have much experience with video compression. But maybe this link helps. http://www.videoconverterfactory.com/tips/video-conversion-problems.html (In general it makes sense to ask the people to make the software. They k…

Hi Willy, Did you manage? YOur plan is clear now, however, you haven't given any detail what the actual problem is. Any error messages? Funny things appearing on the screen? There are more discussion along the lines of the one you posted in the beg…

Hi YTLF, Sorry for the late reply. Have you sorted it out by now? Unfortunately, I'm not very experienced with coroutines, but this little script below is able to handle stimulus presentation and collection in a dual-task. Hope this helps. #init…

Hi , (Quote) No, this does not sound ok. I'm not sure whether your solution makes perfect sense (I haven't quite understood), but I think it is fairly easy to solve it by using some python coding. At least that's how I set up my experiment that ran…
-
Hi Erwin, Well, you have to create the task first (What's the task actually?). Did you do that? Maybe have a look at the beginner's tutorial, to get an example of how a cueing experiment would look like. This will give you some inspiration how to i…

Hi, (Quote) Not sure about that. But in general (at least the BIOSEMI system does so), EEG recordings are send via a parallel port to the recording computer (in that case the laptop), I doubt that many laptops have a parallel port, so I suppose the…
-
Hi, This requires some scripting, but should be doable . First, you need to create the form that has all the buttons you need. Put it somewhere in the experiment. It doesn't really matter where, but set its run if statement to never. Next, put an …
-
Super sorry for the delay! attached an experiment that implements somehting that you wants, right? Actually, I was surprised how easy it was. Good luck, Eduard
-
Hi, Check out the step-by-step tutorial, in step 3-5 (I think) they describe in detail exactly the same thing you want to have. good luck, Eduard

Hi Charlotte, Check this out: http://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_gui/py_video_display/py_video_display.html I have never tried it and have no experience doing it, but from the quick look I had on their website, …
-
Hey, There are a lot of ways to do that. Below just one example. 1) Put an inline_script in the beginning of your experiment and paste following code in the preparephase # make a list with a 5 groups (basenames are enough)items = ['CocaCola','Nes…

Hi, This link might be lead you into the right direction. https://stackoverflow.com/questions/15109548/set-pythonpath-before-import-statements Good luck, Eduard

What I meant is that just taking a sample from the current eye position doesn't tell you whether the participants was fixating at that location or whether his/her eyes just happened to be at that location. It would be possible that your eye position…
-
Hi, This seems to be an issue related to the Mac version of OpenSesame. I just tried it on Ubuntu and it worked just fine. Can you try to strip down the experiment as much as possible, while still preserving the crash and report this issue than on …
-
Hi, Is the only problem that no eye data is written to file, or does non of the eyetracking work? I suppose, you selected the corrected eyetracker in pygaze_init? Do find out whether you can actually access the eyetracker, try to do something like…
-
Hi Zsc, Not sure about the correct order (I usually do it by trial and error), but in general your procedure sounds pretty good. If you are worried about the timing, there is only one way to make sure, and that is testing. Good luck, Eduard
-
Hi Chris, Check out this discussion: http://forum.cogsci.nl/index.php?p=/discussion/349/open-online-data-collection Doesn't sound very promising.... Eduard
-
Hi, If you are only interested whether your eyes are to the left or the right of your middle, this procedure is fine conceptually. If you want to know when fixations occurred, you would want to make sure that the current eye position is stable acro…

Hi Briony, I'm not aware of any systematic benchmarks test being run, but I vaguely remember that the timing of the voice key does not work very reliably. See this discussion. Probably it is best if you test it for yourself. Good luck, Eduard
-
Hi, If you reset the feedback in the end (or the beginning) of a block, only the most recent block should be used for the computations. So just drag the reset_feeback item in the beginning of your block_sequence and you should be set. Good luck. …
-
If you don't care about the automatically computed response time, define the variable total_response_time in the beginning of the experiment once. For example in an inline_script: var.total_response_time = 0 Eduard

Hi, Do you mind sharing your experiment and/or your sequence? What you describe shouldn't happen and did not happen when I just tried it. But maybe there are differences in the order of items that I haven't taken into account. Eduard
