How to enter text without typing ? Usage aspects of the Sibylle communication aid
Résumé
We present SIBYLLE, a communication aid that permits persons suffering from severe physical disabilities to enter text to any computer application. The system consists of a set of keypads allowing to enter characters or full words by a single-switch selection process, in which the user confirms the currently highlighted selection key. It also comprises a sophisticated word prediction component that calculates dynamically the most appropriate words for a given context. This component is auto-adaptive, i.e. it learns on every text the user has entered and thus adapts its predictions to the user's language.
