Hi @raynlaze, thanks for your query. Certainly, hiding the mouse cursor globally is not a feature that is available via the Tobii Core SDK, so you would have to investigate a solution using a more general methodology within .NET
From what I have seen online, a possible workaround may be to create your application fullscreen and use Cursor.Hide() within this window.
Other possibilities such as fixing the mouse position on screen but I don’t think that would work for your needs?
In any event, you would be overriding global settings via a single application which is not something generally recommended. Perhaps you could elaborate on your project goals and we could find a suitable solution for you.
