Eye trackers are used as well for those who unfortunately cannot move anything but their eyes. That's the case in very bad/late ALS cases. This technology might really be life changing for the very advanced cases of ALS - they often lose the ability to vertically move their eyes, which makes it very very difficult to work with eye trackers. Really hope they'll make something like this available to the public.
