• Do-It-Yourself AAC: Co-Designing User-Programmable AI Communication Tools with People with Aphasia

  Jong Ho Lee, Stephanie Valencia (2026) — Proceedings of the 2026 CHI Conference on Human Factors in Computing Systems (CHI '26)

  Lee and Valencia explore how people with aphasia (PWA) can become designers of their own AI-powered augmentative and alternative communication (AAC) tools rather than users of rigid, pre-built systems. The authors note that aphasia, a language disord…

• visiBabble for Reinforcement of Early Vocalization

  Harriet Fell, Cynthia Cress, Joel MacAuslan, Linda Ferrier (2003) — Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper presents visiBabble, a real-time system that detects syllable-like vocalizations in infant babbling and responds with brightly coloured animations as visual reinforcement. The system targets infants at risk for speech impairments due to co…
