The GazePlay Project: Open and Free Eye-Trackers Games and a Community for People with Multiple Disabilities

In order to develop and enhance an augmentative and alternative communication (AAC), gaze is often considered as one of the most natural way and one of the easiest to set up in order to support individuals with multiple disabilities to interact with their environment. For children who start naturally from scratch, who have in addition such difficulties, it is a strong challenge even to acquire or to support the required basic knowledge. Games are often considered a good way to learn. Games designed for eye-trackers, i.e. electronic devices able to compute the position of the gaze, allow children to discover the power of their eyes and the consequences of the actions triggered by their gazes. Video games can be a good way to improve basic requirements as gaze fixation and gaze pursuit as well as conventions like rewards or dwell interactions often used in AAC tools. In this article, we present the GazePlay project which main contribution is a free and open-source software which gathers several mini-games playable with all eye-trackers including low cost ones.
