Assistive technology has been focused on this for a while.
My brother had severe cerebral palsy and for years (80s-90s) communicated via analog technology, a literal alpha/iconography communication board, which he could tap on with a head wand. By 2000 he had a digital voice, but still had to use a wand.
Stephen Hawking demonstrated eye sensing technology almost as soon as it was invented and that’s been over a decade ago.
In most cases, there is a definite aspect of “bespokeness” to implementing assistive consumer communication technology, but the barriers implementing the same for an able audience would appear much lower.
