That could be interesting, eye tracking is often expensive and can require a "just-right" type of setting. Reducing that barrier can be huge for many.
I think outside of a single solution like eye-tracking there's a lot of room for a device like this to be much more adaptable to a broad range of conditions. There's so much variation of how physical symptoms can present, even within a single disease, that it can be really difficult (and expensive) to customize hardware for an individual... and degenerative diseases can take constant readjustment and new hardware.
The hardware barrier seems endlessly frustrating — you have an off-the-shelf device like a joystick/keyboard/mouse that was originally designed for hands, being used by feet and with mouths...
...a good example of hardware reduction making a meaningful impact was the advent of reliable portable touchscreens — people could actually start directly touching the interface without some of the ergonomic constraints of a mouse and keyboard. You can reliably surf the web on an iPad using your nose. Imagine trying to do the same with an off-the-shelf joystick or mouse.
