Giving Meaning to Movements: Challenges and Opportunities in Expanding Communication by Pairing Unaided AAC with Speech Generated Messages
Kabir and colleagues tackle a long-standing split in Augmentative and Alternative Communication (AAC): aided AAC — speech-generating devices, symbol boards, tablet apps — produces standardised, intelligible output but is slow, visually demanding, and…

I, Robot? Exploring Ultra-Personalized AI-Powered AAC; an Autoethnographic Account
This paper is a multi-month autoethnographic study by an AAC (Augmentative and Alternative Communication) user-researcher who fine-tuned a personalized large language model on his own communication data and then used it as the suggestion engine in hi…

Designing AAC Interfaces for Commercial Brain-Computer Interaction Gaming Hardware
This paper explores repurposing a low-cost commercial brain-computer interface (BCI) gaming device — the OCZ Technologies Neural Impulse Actuator (NIA) — as an input device for augmentative and alternative communication (AAC). The NIA is a headband t…
