• Speech Dasher: A Demonstration of Text Input using Speech and Approximate Pointing

  Keith Vertanen, David J.C. MacKay · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS 2014)

  This paper demonstrates Speech Dasher, a multimodal text entry system that combines speech recognition with the Dasher zooming interface to enable fast, corrected text input using only voice and gaze direction. The core problem addressed is that while speech dictation is fast,…

• The Feasibility of Eyes-Free Touchscreen Keyboard Typing

  Keith Vertanen, Haythem Memmi, Per Ola Kristensson · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This poster paper proposes a novel approach to eyes-free touchscreen typing where users imagine a QWERTY keyboard somewhere on the device and tap out an entire sentence without seeing the keyboard and without receiving any intermediate feedback about letters or words typed. This…

• Adapting Word Prediction to Subject Matter without Topic-Labeled Data

  Keith Trnka · 2008 · Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper proposes a method for adapting word prediction systems to the current topic of discourse without requiring human-labeled topic categories in the training data. Word prediction is a key feature of Augmentative and Alternative Communication (AAC) devices, where it…

• Corpus Studies in Word Prediction

  Keith Trnka, Kathleen F. McCoy · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  This paper from the University of Delaware investigates how the choice and combination of training corpora affects the performance of statistical word prediction systems for Augmentative and Alternative Communication (AAC) devices. The fundamental challenge is that AAC users…

• SIBYLLE: a system for alternative communication adapting to the context and its user

  Tonio Wandmacher, Jean-Yves Antoine, Franck Poirier · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '07)

  This paper describes the latest version of SIBYLLE, an augmentative and alternative communication (AAC) system developed at the Université François Rabelais and the Université Européenne de Bretagne for users with severe motor and speech impairments — including cerebrally and…

• Semantic Knowledge in Word Completion

  Jianhua Li, Graeme Hirst · 2005 · Proceedings of the 7th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '05)

  This paper proposes an integrated word-completion system that combines semantic knowledge with traditional n-gram statistical models to produce more contextually appropriate predictions for users with linguistic or physical disabilities. Standard word-completion systems use…
