Gaze Talk

This is a recommended project.

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).

From the Authors:

The goal of the GazeTalk project is to develop an eye-tracking based ACC 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.

Main features:

type-to-talk
writing
email
web – browser
Multimedia – player
PDF – reader
letter and word prediction, and word completion
speech output
can be operated by gaze, headtracking, mouse, joystick, or any other pointing device
supports step-scanning (new!)
supports users with low precision in their movements, or trackers with low accuracy
allows the user to use Dasher inside GazeTalk and to transfer the text written in Dasher back to GazeTalk

GazeTalk 5.0 has been designed and developed by the Eye Gaze Interaction Group at the IT University of Copenhagen and the IT-Lab at the Royal School of Library and Information Science, Copenhagen.
