    Hi! I have a bit of strange feedback. 🙂 I’m going to be streaming/recording from an arcade cabinet which has a 4:3 CRT monitor with a maximum display resolution of 640×480. (The other supported resolution is 320×240. 😉 ) At 640×480 the configuration tool is too tall for the screen and gets cropped, and there is no scrollbar to access the obscured options.

    I’ve found I can work around this by manually editing the configuration file in C:/Users/<username>/AppData/Local/Tobii/Tobii Streaming Gaze Overlay/ — for example, setting Offscreen to true in order to disable the live preview. Of course, this requires closing and re-opening the tool to change settings, but this is manageable enough.

    Other than that, everything seems to work great! Thank you for developing this tool. 🙂

    Thanks for feedback. I will try to think about how to fix it. Soon we will publish a new release with improved performance on 4k screens.

    Hi, I am thinking about getting the tobii 4C, but have a couple questions. When you record the footage with gaze overlay, how is it saved? 1. what are the file types, and 2. I’m assuming you have separate files then for the screen display and the gaze overlay?

    Thanks!

    Hi!

    You use video capture software (like OBS or xSplit) where gaze overlay is composed on top the video stream. So you get a single video file in the end. If you want to store the data for analytical purpose please contact Tobii Pro https://www.tobiipro.com/contact/contact-eyex-for-research/

    Would it be possible to Add easily, an Image file that would fit inside the GazeOverlay SHAPE ?. Adding the possibility to Customize not only the color but, the whole Overlay visual Appeal. SO we can have custom GazeOverlay cursors like this one

    I wanted to do it myself but… couldnt find source code for Tobii Gaze Overlay…
    Neither the source code for Tobii itself. Which i think could be GREAT To be able to customize the WHOLE GUI…

    Then i readed this post Saying Source is not available, yet!
    Well i either cant wait for The source to come out. OR The function to be implemented >.<

    Much Appreciated for your reply.
    Thanks for your answer,Alex.I remember there was a version which written by Oleh,but i can’t find it now. It’s easy for me to understand with annotation after the code.The version you provided to me is nice,however, i have difficulty in applying it to my task.I wonder if it’s possible for you to provide that version of code to me.It’s doesn’t matter if you’re not convenient!
    Best regards.

    Hi @leengu !

    What problems do you get when you try to use the sample code?

    Dear Alex,
    Which line represent the eye position? Is it a float value that i could use to calculate? Furthermore, i would like to know the sample frequency.
    Sincerely yours
