Design and Validation of Software Based on Eye-tracker to Improve Attention in ADHD: Validation study

Attention Deficit Hyperactivity Disorder (ADHD) is a common neurobiological condition affecting school-age children. One of the main symptoms is short attention span, which is a key factor of poor academic performance, especially in tasks requiring long term concentration. Children with ADHD often jump from task to task without finishing any of them. They feel trapped by any task that takes longer than the time they’re able to stay focused. Improving this skill usually requires breaking tasks into smaller segments while working to increase the child’s attention span. The goal of this research was design and validation of a software package based on Eye-tracker to improve attention in children with ADHD.

This research is a validation study on the population of the psychologists that were expert in the field of learning and cognitive deficits in children and teenagers, and the educational technologies, among which ten people were purposefully selected. The tools used in this research included a game made by Unity, and Tobii Eye Tracker 4C. For content validation, a questionnaire was prepared by the technical team, and filled by psychologists. Software validity was calculated using the Kappa coefficient.

After applying requested revisions, the data of the questionnaires was analyzed, and the software validity was 94.8% in terms of Kappa coefficient.

The software seems to have appropriate content validity and may be advised to be used to improve attention in children with ADHD.
