• Hi Sebastiaan, Thanks for the work-around! Any plan for integrating this function into OSWeb at some point? Being able to import condition files would allow for much flexibility in designing experiments... Thanks, Han

• Hi @Edwin , Thank you for your reply! I have some follow-up questions. I'm now using the PyGaze plug-in in OpenSesame with EyeLink. I assume that DISPSIZE is automatically set as the experiment's resolution and I don't have to set it explicitly? Do …

• Dear @Edwin I noticed the same problem as @ChrIm pointed out. For example, this is a calibration report on the Tobii T60: http://forum.cogsci.nl/uploads/047/1UWI6YZJU4IC.png While I'm pretty sure that I was following the targets closely, the accura…

• Hi, I am having the same error with the latest version of OpenSesame. I am able to run the experiment full screen using expyriment and psychopy backend but not the legacy backend. Here is my experiment https://drive.google.com/file/d/1aTYxVVqzueYs…

• Hi @sebastiaan, I just wanted to confirm that the method mentioned here: self.experiment.items["my_loop"].repeat = 4 is still working, since I have a similar problem. My experiment has 4 blocks with the same trial sequence, but the nu…

• Hi @Edwin, I am using an older version of PyGaze where we only have the tobii backend because we run a Tobii T60. I think it's time for me to update the package, but it would be really nice to add pupillary measures to it! Han

  in [solved] Pupil size obtention Comment by hanzh September 2018
• Hi @Edwin , I was wondering if this feature is included in the latest version of PyGaze. I also found it'd be very helpful to record pupillary data. I believe that in my current version, pupil size is included for the eye tribe tracker output but n…

• You can take a look at the R package brms. They have very similar syntax to lmer in terms of writing model formula. Here is a short tutorial of how to fit non-linear models I found online https://cran.r-project.org/web/packages/brms/vignettes/brms_n…

• @ester I've been in contact with a SMI support staff about a problem with their mobile eye tracking system. Here is the email: supportus@smivision.com I think you can ask them for the files. They actually reply pretty quickly. Good luck.

  in Need dll files from SMI Comment by hanzh August 2018
• Just came across with @sebastiaan 's code snippet. I found it to be very useful. My question is: I noticed that the fixation's coordinate and the pupil size were the median of samples - is this usually how EyeTribe data is handled? For now, I'm impo…

• Hi all, I don't know if anyone is still following this, but I also have the problem of unable to set the backdrop. I inserted an inline_script based on functions from the old Pygaze and it worked for both pygame and expyriment backend (didn't try o…

• Hi @brusil , Did you find any consequences of leaving these parameters as default on your eye-tracking data? Do you have to set these parameters correctly to get the correct coordinates? Also calling @sebastiaan here! Thanks! Han

  in Eye-tracking - Setting physical screen size and distance to participant Comment by hanzh October 2017
• Hi guys, It might not be fully relevant to this topic but I am curious about the benchmarks provided at the beginning of the file. For example, fixation threshold: 1.5 degrees speed threshold: 35 degrees/second acceleration threshold: 9500 degrees…

• Hi, I have some updates on the dual eye tracking: I managed to make to two eye trackers start recording at (roughly) the same time. The computers do not have to be physically connected as long as they are in the same LAN. We have a sender computer…

  in Using OpenSesame/Pygaze for dual eye tracking? Comment by hanzh January 2016
• Thank you so much @Josh and @sebastiaan ! I am really interested in the idea of connecting multiple eye tribe servers to a single OpenSesame experiment. I guess this could be constructed as a main computer with a mirror computer, like Josh said. Or …

• Hi Sebastiaan, Thanks for your reply! We are playing multiple pieces of music and subjects will press a key to indicate they've finished! We are using pygame.mixer.music to play the music and we set some variables to track names and lengths of the …
