Hi Shri, It is unclear what you're after. Are you trying to obtain files generated through an eye tracker? Or are you wanting to do eye tracking with your webcam? If you're just looking for an example files, you can find two here: http://www.pygaz…

Hi Helio, Thanks for the elaborate description! Just to get my head around the issue: The PyGame back-end is working perfectly, but you're unsure about its timing accuracy, correct? How come your stimuli are not compatible with PsychoPy? As for yo…

Hi, As the error message indicates, this is not an error in the code at all, but simply indicates that you have not provided data. The error message indicates that it expects a data folder to exist (obviously at least one data file in the valid for…

Hi Helio, Yes, there is! You could add an inline_script item, and use the following code to its Run Phase: eyetracker.calibrate() You can make this inline_script item part of your trial sequence item, and use the "Run if" statement to o…

So you've used the tracker and OpenSesame and the PyGaze plug-ins in another experiment, and that does run? Could you confirm whether that other experiment still runs, please? If that other experiment runs using the very same software, it seems lik…

Hi Brandon, This is a consequence of the inherent limitations of GazePoint's OpenGaze API. It works by adding a log message to a particular sample, and thus will log the 'active' log message when a sample is logged. This can lead to logging the sam…

Did you set the drift check to "fixation triggered"? Pressing Q during a drift check should start a calibration. (Handled in this line.) What output does the Debug Window show?
-
In addition to @eduard's comments: Did you install the necessary libraries from the Tobii SDK? Do you have the correct license to access the 4C through the SDK?
-
To give a more specific answer to your second question: Before calling the stop_recording function, data is streamed and logged (in a local buffer). When you call it, the buffer is synced to disk (to the log file). By calling the log function, you'…

Hi Ali, We'll need a bit more info to find out what's going on. Would you be able to post the content of the Debug Window, and if at all possible also your task? Cheers, Edwin

Hi all, Sounds like an accurate diagnosis, @sebastiaan! Tobii did their own implementation, so you might be able to ask the Devs about it on GitHub, @heliocuve. You can open an issue there, and tag them. (Or open the issue, and I will tag them.) …

Hi GE, Currently, the points are hard-coded in the Tobii back-end. The only option to introduce a 9-point calibration would be to dive into the code, and change this line. Cheers, Edwin

Hi Liya, Oddly, your output suggests that actually things are going fine. The start_recording function is run, says it returned 0 (suggests no errors in starting the recording), then starts realtime mode fine, then successfully waits for the 'bloc…

Great to hear, Tom! :smile:

Hi Jaron, To add to @TomArmstrong's overview, specifically about your OS question: Please keep in mind that a lot of eye trackers are essentially Windows-only. OpenSesame and PyGaze work across platforms (Windows, Linux, OS X), but that doesn't mea…

Locked as this is a duplicate of this thread.

You didn't install the pylink library from SR Research. This library can be obtained from the SR Research support forum, and is required for communication with EyeLink trackers.

UPDATE: The GazePoint OpenGaze API malformed XML bug should be fixed with the latest commit. Grab the code of GitHub directly, and update your local PyGaze installation with it. See here: https://github.com/esdalmaijer/PyGaze

Hi Tom, Good to see you here! Thanks for flagging this up. It's due to a bug (malformed xml) in the GazePoint API. There are two workarounds: 1) You can ask GazePoint for a pre-release of their API, which had the bug fixed. 2) We built a workarou…

It's the blue PyGaze button, yes! It should have an eye shape in the centre (black pupil and blue iris), and four blue dots around it. It's named pygaze_init (visible if you hover the mouse cursor over it), and appears underneath the PyGaze label in…
-
Hi, and welcome to the forum! :) The PyGaze_init plug-in can be set to run a dummy mode. There are two options: 1) Dumb dummy runs without actually doing anything, and 2) Dummy allows you to simulate eye movements by using the mouse cursor (note th…
-
Hi Tomas, Hope you're well, and thanks for the feedback! :) It sounds like the conflict is between pylink and PsychoPy. I would recommend trying the no-SDL version of pylink, which you can download from the SR Research support forum. The regular p…

Hi Courtney, Would you mind providing a little more detail, please? The GP3 is supported in PyGaze by default, but there are a few bugs in GazePoint's latest SDK. Those are fixed in a pre-release version, though, so I would be happy to share that …
-
Hi Han, Unfortunately, the EyeTribe has no built-in support for this. That means you would have to code your own interface. This is not trivial, but should be doable if you have prior programming experience (and are familiar with Python sockets). B…
-
The iViewX API file you're referring to is part of the proprietary software developer's kit (SDK) from SensoMotoric Instruments (SMI). GazePoint is a wholly different company, selling the GP3 range of eye trackers. Are you sure you're asking for t…

Hi @lindatovar, The link you posted has been removed for being seemingly completely unrelated. If your account is genuine (i.e. not a bot or human spammer), please do feel free to outline why you think that particular URL should be included. All t…
-
Hi @khushbu, You've posted a link to a website that was created rather recently from an account that is very new. In addition, the URL you used has (seemingly) nothing to do with the library you reference, and that pops up very regularly in spammy …
-
Hi @hanzh, Yes, it should be possible! What Tobii back-end are you using? Are you using tobii or tobii-legacy in the latest version of PyGaze, or perhaps using an older version that only has tobii (which is the current tobii-legacy)? Edit: I just …

Yes, I wrote that! However, the implementation rests on SMI's API, which handles the calibration and validation animation. The awkwardness in the linked video is the SMI API and OpenSesame handing over control over the display. Sometimes on the fir…
