Problem with Tobii EyeX controller

pimrat

Hi. I'm new to OpenSesame (or any research stuff). But I already have a Tobii EyeX controller, and need it to be work on OpenSesame for my Master degree research. I tried to run eye-tracking study and it shows "ImportError: No module named tobii_research". What might be wrong? Can anyone help?

So, now i downloaded Tobii SDK and copy "tobii_research.py" into "OpenSesame>pygaze>_eyetracker. And now the error is "ImportError: No module named tobiiresearch.implementation".

Hi and welcome to the forum

I don't have experience with Tobii eyetrackers myself, but judging by the manual your Eyetracker is not supported:
http://osdoc.cogsci.nl/3.2/manual/eyetracking/pygaze/#supported-eye-trackers

This problem was already discussed here:

Hi Pimrat,

Recently, the Tobii developers have actually added decent support for Tobii to PyGaze. If you're running the latest version of OpenSesame (3.2.1), then all you have to do is install the tobiiresearch package, which you can do through the Python package manager (under Menu -> Tools).

Does that clear things up?

Cheers!

Thanks for your answer @sebastiaan . I'm not sure what i did wrong (as i have no experience on programming). So I tried to start again from scratch. Installed the 'tobii-research' package. Run the experiment again (default eye-tracking template) and now it came up with:

item-stack: experiment[run].pygaze_init[run]
exception type: IndexError
exception message: list index out of range

How can I fix it?

Thanks

Hi Pimrat,

I think it's the issue (+ fix) described in this post:

That's work. Thanks @sebastiaan ! There is no more error when i run the experiment again.

However, when i selected tracker type in 'pygaze_init' to be 'tobii', the experiment is at only on 'preparing experiment...' page. I waited for a long time, nothing happened. Then I press space bar and it said the experiment finished successfully.

I tried with the simple dummy, it worked fine.

I'm really appreciate your help as there're so many questions here.

Thanks

The problem with running the experiment with 'tobii' in 'pygaze_init' still be there. I tried google it, but can't find anything. I'm so confused. Please help

sebastiaan

Could you upload the experiment here? I don't have a Tobii to test it myself, but perhaps I can nevertheless see what's wrong.

pimrat

Actually, I used the default eyetracking template to try out. Didn't change anything. Except choosed 'tobii' in pygaze_init in stead of the simple dummy.

sebastiaan

Ah, I see. One thing that comes to mind is that pygaze_drift_correct may be blocking the program. I've heard that there are some issues with the Tobii implementation of this. What happens if you simply remove this item?

pimrat

It still be the same

Then it sounds like there's some issue setting up the connection with the Tobii. (I'm just guessing here.) @Dani.rnc Based on your experience with the Tobii, do you know what might be wrong? Which steps she might have missed?
