This study analyzes the role of the machine as a communicative partner for children with complex communication needs as they use eye-tracking technology to communicate. We ask: to what extent do eye-tracking devices serve as functional communications systems for children with complex communication needs? We followed 12 children with profound physical disabilities in a special education classroom over 3 months. An eye-tracking system was used to collect data from software that assisted the children in facial recognition, task identification, and vocabulary building. Results show that eye gaze served as a functional communication system for the majority of the children. We found voice affect to be a strong determinant of communicative success between students and both of their communicative partners: the teachers (humans) and the technologies (machines).

This study examines interactions between students with atypical motor and speech abilities, their teachers, and eye tracking devices under varying conditions typical of educational settings (e.g., interactional style, teacher familiarity). Twelve children (aged 4–12 years) participated in teacher-guided sessions with eye tracking software that are designed to develop augmentative and alternative communication (AAC) skills. Assessments of expressive communication skills before and after the testing period demonstrated significant improvements. 164 sessions conducted over a 3-month period were analyzed for positive engagement (e.g., gaze direction, session time) and system effectiveness (e.g., lag time, gaze registration) between integrated and non-integrated systems. Findings showed that integrated systems were associated with significantly longer sessions, more time spent looking at the screen, greater proportion of gaze targets registered by the system, and higher response rate to prompts from teachers. We discuss the implications for the facilitated use of eye tracking devices in special education classrooms.
