VR Eye-Tracking Add-on Droolon F1 for Cosmos（Basic Version） https://a.co/d/asAAZwT

You can use it with any headset cause the data it provides is independent of the headset. Not sure how accurate that one is in particular.

Eye tracking data is not particularly complex nor super sensitive in nature. Once the sensor is calibrated it just sends over two vectors.

They won't share information on where you look, but they will share info on where you 'click', which is used to navigate apps. IIRC you are supposed to use your fingers to do this, and other actions, but I imagine that Apple's accessibility team will have an alternate mode for people with motor limitations. It could be a long-blink, or rapid blinking, for example.

I think that makes sense but a startup is going to have a hard time delivering something better between now and January if they start from scratch.

But maybe I’m wrong, it might be a purely software based problem that can be solved quicker.

Also donning the AVP headset might not be possible for someone with advanced ALS. A fixed outside-in apparatus (probably attached to the patient’s wheelchair) would make more sense.
