GazeTalk is a predictive text-entry system for severely disabled people that has a restricted on-screen keyboard with ambiguous layout. The goal of the GazeTalk project is to develop an eye-tracking based AAC system that supports several languages, facilitates fast text entry, and is sufficiently feature-complete to be deployed as the primary AAC tool for users.

The system is designed for several target languages, initially Danish, English, Italian, German and Japanese.
