AAC, social communication, and community engagement
If the point of AAC is to support a person's communication, the way we evaluate AAC should reflect that — not just count words per minute.
A recent arXiv paper on AAC and social communication makes a clean argument: too much of the AAC literature evaluates devices and systems on narrow proxies — vocabulary accuracy, selection speed, syntactic correctness — and too little on whether the person using the system is actually able to participate in social life.
The shift the authors want
They argue for outcome measures grounded in participation: conversations initiated, friendships maintained, choices honored, community roles inhabited. These are messier to measure than word-error rate, but they are what AAC is for.
This is consistent with where ICF-aligned thinking and quality-of-life research in disability have been heading for two decades. It is not a rejection of efficiency — fast, accurate selection still matters — but a reframing of what success looks like.
Why this is relevant to supported communication
The same shift in outcome measures applies to letterboard- and keyboard-based methods used by nonspeaking autistic people. The right question is not only "can this person produce a verifiable message in a blinded paradigm?" — though that question deserves study — but "is this person now able to participate in conversations, friendships, education, and decisions about their own life?"
If yes, that participation is itself an outcome the field should take seriously.
