Thank you, so not yet an option for me; I doubt my posture and sitting position is regular enough that calibration would work for me.
Might, at some point, be a welcome addition to a touch pad though. If you touch the pad and your pointer is far away to where you're looking, jump to the area and do the fine tuning with the fingers.
I already do that without the need of a touch pad, just use your numpad keys as a mouse if you're on windows look into mouse.ahk. Tobii will snap mouse to where you're looking at and senses mouse is moving. Works great when you want to stay on home row, selecting text with it though, not as good.
