Hi @easy2udev, thank you for your query. I am afraid that for the time being, within the framework of our .NET for both the Tobii Stream Engine API & Interaction Library API, only the Windows operating system is currently supported for consumer levels devices such as the 4L.
Full specifications for the 4L Eye Trackers are available @ https://www.tobii.com/siteassets/tobii-tech/4L-product-sheet.pdf?v=1
Our apologies for the disappointing news, please do get in touch should you require any further information. Best Wishes.
