Application of Eye Tracking for Diagnosis and Therapy of Children with Brain Disabilities

Abstract

Children affected by brain disabilities require a lot of attention and care to improve their life. The quicker the support will be introduced the better effect can be achieved. One of important impairments resulted from the brain disability is a cerebral visual one. In case of children, communicating with whom is difficult or impossible, assessment of vision quality is very challenging and eye tracking methods may prove very useful. The research discussed in this paper was devoted to development of a workspace, which may support the effort of therapists working on improving the quality of disabled children’s life. The important element of this solution is the implicit calibration procedure, making eye movement registration possible. Additionally, there were several stimuli developed and tested with cooperation of therapists from one of associations for children with developmental disabilities. Initial tests confirmed usefulness of the elaborated solution, which facilitates children’s vision assessment based on the eye movement signal and may be used for a further children therapy.
