Posted in Pygaze forum with no response: Please help with Gazepoint GP3 and Open Sesame

mtuvlin

I posted in the Pygaze forum but got no responses. 

First, forgive me but I do not have a programming background so I don't understand most of the discussions on this board.

I'm trying to run an eyetracking experiment using a Gazepoint GP3. I've created a very simple experiment using the PyGaze eye-tracking template where the test subject views a short video and needs to make one keystroke at some point during the video. The Gazepoint eyetracking software can record fixations and heat maps, etc. but not keystroke entries. Just today, the people at gazepoint emailed and said I need to contact the Open Sesame developers to figure out how to use it to control their Gazepoint Control" program.

I can use the Gazepoint software to run the experiment and it works. I can use the open sesame program and it works as well but I am trying to see if it is possible for Open Sesame to control the "Gazepoint Control" program of the eyetracker to start recording (so I have heat map & fixation data). If I try to use both programs at the same time (run the experiment in Open Sesame and then hit "record" on the gazepoint software) it opens the video in two different windows

 I don't know if this will help but here is overview screen:

Any help would be most welcome.

Thank you,

Hi @mtuvlin

I'm not super familiar with Gazepoint myself, but I’ll try to help anyway!

Have you seen this thread already? Using Gazepoint GP3 HD with PyGaze and OpenSesame — Forum. In particular, the second-to-last comment might be helpful.

From what I understand, the issue could be that you’re manually pressing "Record" in the Gazepoint Control software — but this shouldn't be necessary. The pygaze_start_recording item in your OpenSesame experiment is what tells the tracker to begin recording. So if you're using both at once, that might explain why the video opens in two different windows?

According to the forum post, the recommended procedure is:

• Start the Gazepoint Control app and make sure your eyes are detected (but don’t press Record).
• Leave that window running in the background.
• Then start your OpenSesame experiment. (It might take a while to launch, but that’s normal.)

Also, just to double-check: make sure that in the pygaze_init item, the tracker type is set to 'OpenGaze'. That’s the option compatible with Gazepoint. Also check that you have the last versions of Opensesame and Pygaze on your device.

Let me know if it helps!

Thanks so much for your help. I'll start trying your suggestions to see if they work.
