  • Thanks so much for the offer, @cesco! Unfortunately, we cannot legally host those kinds of files. However, people who have bought an SMI device and the SDK in the past have a legal right to the SDK. I'm by no means informed enough in legal matter…
  • Hi Roberto, It might well be! Could also be an issue with your laptop's OS. To be honest, I have no clue, as I didn't develop the media_player_mpy. @sebastiaan and @Daniel should know more! Good luck! Edwin
  • Hi Zargol, Thanks! Doing rather well here; really enjoying the new position and the town! Hope you're doing well too? As for your question: This is totally possible, but would require some additional scripting within the above example. Specifi…
  • Just to update the issue on this platform too: The EyeX does not seem to be supported by the new Tobii SDK, which means the current tobii TRACKERTYPE is unlikely to work with the EyeX. (To be honest, I'm a bit confused by the specifics, but it seems…
  • Interesting issue! Any ideas on how to solve it, Sebastiaan? (You're the encoding nerd )
  • As far as I am aware (which is only through Tobii's information), you'll need the license to make the Pro SDK work. There is still a tobii-legacy option built into PyGaze for older models, but that's only for the models that use the old SDK, and I d…
  • Hi Liat, That's a very clever way of doing it! I think what might be happening is that you only changed the drawing function after the item was already initiated and prepared. In what phase did you add your code? ("Prepare" or "Run"?) I also t…
  • Hi Roberto, That is very weird; I've never seen this particular issue. What back-end are you using, and how are you presenting the videos? What happens if you change back-ends, or the way you play your video? Cheers, Edwin
  • As @sebastiaan mentioned two comments up, the DLL is part of the SMI SDK. It's proprietary, so I'm afraid I can't upload it.
  • Hi Roberto, Would you mind specifying what you mean by "If the Eyetracker is not calibrated"? Do you mean when you use dummy mode, or do you mean when you don't calibrate the tracker but it is active? In addition, an exact error message would …
  • Hi Moreno, Amazing, thanks for the update! That missing space is very likely to have been the cause of the lxml hickup, as it would fail to understand that VALUE="0"DUR="0" actually means VALUE="0" AND DUR="0". Cheers, Edwin PS: I totes ca…
  • Heya! Thanks for the elaborate description and for posting the full traceback, those are very useful! I hope you don't mind, but I changed your post ever so slightly by putting the traceback info between ~~~ flags to make it render as code. This …
  • Hi Christina, To provide a general response to this: EyeLink: Monocular, whether it's the right or left eye depends on which eye you're recording (you can set this in the EyeLink UI interface). EyeTribe: The mean of both eyes if both eyes a…
  • Hi all, Recently, Tobii has implemented support for the new Pro SDK. Before there was already support for the old Tobii SDK. According to Tobii, the 4C should work with the new Pro SDK, and thus also with PyGaze, but they do say you require the l…
  • Heya! Firstly, it's probably good to distinguish two things: 1) There is PyGaze, a library that allows you to interface with eye trackers of different makes (SR Research's EyeLink, SensoMotoric Instruments, Tobii, EyeTribe, and GazePoint). 2) The…
  • Hi Tanto, That's a very good question, and I'm afraid I can't quite answer it, as I don't have access to a 4C. Tobii would be in a much better position to answer your questions, as they actively develop PyGaze support for their Tobii Pro SDK. …
  • Hi both, Important disclaimer: I do not have a 4C, and no affiliation with Tobii, so I don't know anything for sure. What I do know, is that Tobii did mention that the 4C should work with the new Pro SDK, which is supported by PyGaze (and by e…

  • Hi Dian, Does this problem occur when you use PsychoPy as the display type? Cheers, Edwin
  • Hi Amelie, The Tobii developers advice that you should contact Tobii for licensing etc. if you'd like to use the 4C for research purposes. They also mentioned that it should work with the new Pro SDK (which is supported by PyGaze). Also, witho…
    in Tobii 4C Comment by Edwin March 6
  • Hi Chiara, Neither of those are currently supported, as we don't have access to them. In general, the process is that people who have a particular eye tracker volunteer to develop a back-end themselves, or they send me a device and I do it for th…
  • Hi Michif, We currently don't have plans in that direction, because none of us have access to a Cambridge Research Systems Livetrack system. I'd be happy to guide you (or anyone who is interested) through the process of writing PyGaze support for…
  • @Enzo: The issue was probably introduced in an upgrade in Tobii's software, so it might well be that downgrading the Tobii Pro Python module would have worked. However, the issue seems to have been sorted already, so please do try upgrading instead
  • Hi all, That seems to be an issue with the underlying Tobii Pro SDK... Unfortunately, I don't do the Tobii development myself anymore, due to not having access to a Tobii tracker. I've opened an issue on GitHub to make them aware of it, and ask f…
  • Just to keep everyone informed on this platform too: Tobii has looked into the issue, and they seem to have fixed it with the latest code on GitHub! Would you be able to download it, and see if it solves your issue?
  • Hi! Unfortunately, Pupil isn't supported through PyGaze at the moment. It's technically possible, though. So if you or anyone else has the resources, please do go ahead! Cheers, Edwin
  • Are you sure you used the example as above? The following typo in line 3 would result in the error you mention: if button in None: Here, in should have been is. If you did copy it without error, then try the following instead of line 2: …
  • Solved! After some further digging, we found out that it was in fact the variable naming that caused the error. This should be solved in the next JASP release, and is also avoidable by using non-similar names (specifically: unique two first characte…
  • Supported brands of eye trackers are EyeLink (SR Research), EyeTribe, GazePoint (via OpenGaze API), SensoMotoric Instruments (SMI), and Tobii (the old SDK as tobii-legacy and new Tobii Pro SDK as tobii).
  • Great to hear the experimenter PC at least still works! I honestly don’t know what could be going wrong, and won’t be able to debug the issue without extensive information on your current setup and the runs. For example, my earlier question about th…
  • You’re using an older function of PyGaze. Please download a newer version from either the website or (better) from GitHub. Sidenote: You’re likely to prefer running your experiments not from IDLE, but using a batch file.
