I was wondering if there’s an out of the box solution for capturing an area the user is looking at on the screen (or a specified area of the screen) and streaming video of that to another window, so you could kind of visually enlarge and display the area of focus.
If not, can any developers tell me if this seems like a feasible thing to achieve with the current libraries available in the C# SDK? Thank you.26/07/2021 at 11:49 #20910Grant [Tobii]Keymaster
Hi @jhcover, thanks for reaching out. You will be pleased to know that Tobii already provide and out of the box solution for streaming user gate over the internet in real time to a receiving system.
Unfortunately, the software does not support an enlaring of the area of focus and indeed that would something continually in flux, so not an ideal solution.
Please check out Tobii Ghost @ https://gaming.tobii.com/software/ghost/ and let us know if it meets your needs. Please bear in mind that for the time being, Tobii Ghost supports only the Tobii Tech range of eye trackers such as the ET5 and 4C. Best Wishes.26/07/2021 at 17:32 #20911
Thank you for the response Grant.
Really what I want is a magnifying glass you can drag around the screen with your eyes which outputs video to another window. I don’t think Tobii Ghost (as cool as it is) will quite meet that need. Perhaps I will look into writing a custom solution.
If I purchase a Tobii 5 it should come with the development sdk loaded into the device, right?26/07/2021 at 17:54 #20912Alex [Tobii]Participant
If you are trying to build some sort of Windows Control solution then there’s already a solution from Tobii Dynavox:
If you are building something custom, you could try using one of these methods to capture the texture:
and then crop the rect using gaze data from Tobii Stream Engine API:26/07/2021 at 18:04 #20913
Thanks so much for the info, Alex. I will probably try to use that dotnet-window-capture library with the Tobii Stream Engine API just like you said.04/08/2021 at 12:22 #20927Grant [Tobii]Keymaster
Thanks for your understanding Jared. Please do let us know how you get on and if you can, it would be great to share your solution on github for the benefit of other users. Best Wishes.
