• Indirect Text Entry Using One or Two Keys

  Melanie Baljko, Andrew Tam (2006) — Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

  This paper introduces a new descriptive model for indirect text entry — text composition methods where the number of input devices (switches) is significantly smaller than the number of selectable characters. This is the primary text entry paradigm f…

• The Information-Theoretic Analysis of Unimodal Interfaces and their Multimodal Counterparts

  Melanie Baljko (2005) — Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)

  This paper applies Shannon Information Theory to formally analyse and quantify the hypothesised benefits of multimodal interfaces over unimodal ones, with particular focus on Augmentative and Alternative Communication (AAC) devices such as Voice Outp…

• Conversational Agency in Augmentative and Alternative Communication

  Stephanie Valencia, Amy Pavel, Jared Santa Maria, Seunga (Gloria) Yu, Jeffrey P. Bigham, Henny Admoni (2020) — CHI Conference on Human Factors in Computing Systems

  This paper introduces conversational agency as a new framework for studying how augmented communicators (ACs) — people who use AAC devices to speak — participate in and influence conversations. While prior AAC research has focused primarily on improv…

• Evaluating the STANDUP Pun Generating Software with Children with Cerebral Palsy

  Annalu Waller, Rolf Black, David A. O'Mara, Helen Pain, Graeme Ritchie, Ruli Manurung (2009) — ACM Transactions on Accessible Computing

  This paper evaluates STANDUP (System To Augment Non-speakers' Dialogue Using Puns), software that uses natural language generation to enable children with complex communication needs (CCN) to create and tell novel punning riddles. Unlike traditional …

• Designing a Context Aware AAC Solution

  Conor McKillop (2018) — Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '18)

  This student research competition paper explores the design of a context-aware AAC keyboard prototype that uses mobile device sensors — particularly GPS and Wi-Fi positioning — to suggest location-relevant phrases and categories for people with speec…

• State of the Art in AAC: A Systematic Review and Taxonomy

  Humphrey Curtis, Timothy Neate, Carlota Vazquez Gonzalez (2022) — Proceedings of the 24th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '22)

  This paper presents the first systematic review and taxonomy of high-tech augmentative and alternative communication (AAC) devices and interventions within the ACM literature. The authors analyzed 562 articles from the ACM Digital Library and SCOPUS …
