GazeTalk is a predictive text entry system that has a restricted on-screen keyboard with ambiguous layout for severely disabled people. The main reason for using such a keyboard layout is that it enables the use of an eye tracker with a low spatial resolution (e.g., a web-camera based eye tracker).

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 both sufficiently feature-complete to be deployed as the primary AAC tool for users, yet sufficiently flexible and technically advanced to be used for research purposes. The system is designed for several target languages, initially Danish, English, Italian, German and Japanese.
