The biggest issue I see with such things is lack of standarization. For us lucky, "regular" human beings, the interfaces has some standardisation. - Touchpad - Touchscreen - Keyboard We can complain on some minor differences but it's not like going from one device to the other the controller becomes that much different. Ideally, if big tech players are into really making such things useful (eye-tracking, face gestures, etc), there should be standardisations. So if I need those accessible interfaces, they're agnostic as possible to the platform itself.
