eye tracker 5 and Psychtoolbox

[Johanna Hui]

Hi, I am trying to use Tobii eye tracker 5 and psychtoolbox to design an experiment. I tried using PsychToolBoxExample but I only got this :
gaze_data =

StreamError – type:

Error: [1×1 StreamErrorType]
Source: [1×1 StreamErrorSource]
Message: ‘Gaze Data Subscription: Internal Error↵Eye Tracker Address: tobii-prp://IS5FF-100202401201↵Eye Tracker Serial Number: IS5FF-100202401201↵Error: TOBII_PRO_STATUS_SAVED_LICENSE_FAILED_TO_APPLY↵Message: Failed to subscribe to gaze data.’
SystemTimeStamp: 452807885702

. Can someone please help with this? What other information/code about my project should I add so that someone can help?

Thank you

Hi @ryanka, The Tobii Eye Tracker 5 is only designed for consumer applications such as gaming and interaction and will not work with PsychToolBox. You will need to purchase a Tobii Pro Device to operate this software with more info @ https://www.tobii.com/products#eye-trackers

Apologies for any inconvenience. Best Wishes.

Thank you so much for your reply.
We do have eyelink for more precisely eye tracking.
Is there any other way to present just the bubble on top of my screen 🤦‍♀️

[Grant [Tobii]]

Hi! The bubble effect you refer to is ‘gaze overlay’ which is included with the Tobii Experience app and should be directly accessible.

Thank you for your reply.
I can’t find gaze overlay in my Tobii Experience app. Do you mind telling me how to access this function?
The bubble will disappear whenever I open other files or app on my computer.

Did you find a solution to this. I too cannot see gaze overlay on any other windows other than Tobii experience app

[Grant [Tobii]]

Hi Both, the Gaze Overlay bubble will only work within the Tobii Experience Application.

[Nav D]

Why thought. The value of it is to highlight where the user is looking at a screen during work or playing games. What benefit is there to seeing the gaze bubble just inside the tobii experience app? Its only used for calibration and settings isn’t it?

[Johanna Hui]

Yes, I have the same problem. I can’t see the gaze bubble outside the Tobii experience app ,even when it’s minimize 🙁

I have the same issue, I would like to access the eye tracking data in some way, or at least visualize the bubble to pilot my behavioural experiment.
Any developement on this issue @Nav D or @Johanna Hui?

[Grant [Tobii]]

I’m afraid that the gaze bubble will only work within the Tobii Experience App.
