Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disability characterized by difficulties in keeping concentration, excessive activity and difficulties controlling behaviour not appropriate to the person´s age. It is estimated to affect between 4-9% of youths and 2-5% of adults. Assistive technologies can help people with ADHD to reach goals, stay organized and even fight the urge to succumb to forms of distraction. This work introduces a tool designed for people with ADHD aimed at detecting and training their ability to follow a target in a screen playing videos that consist of a circle displayed into five possible positions that changes over the time. The tool is based on non-invasive monocular gaze estimation technique without constraints in terms of user dependent calibration or appearance. The system has been employed and validated in a human-computer interaction (HCI) scenario with the aim of evaluating the user visual exploration. Results show that the tool can be used in complex tasks like monitoring and comparing a user progress after different sessions.
