    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 🤦‍♀️

    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.
