Hi @eyerpheus, whilst the Gaze Aware area is something that can be reconfigured for polygonal elements such as buttons, shapes, etc, this may not be possible to adjust for WPF components such as radio buttons.
However, I am in touch with the developers and we will try to find out if there is a workaround to suit your needs.
It might also be handy if you could kindly share with us the code if possible to speed up resolution. Many thanks.
