ADHD is characterized by two behaviours: impulsivity and hyperactivity. Those behaviours manifest in different forms. One of them is impulsive speech, meaning that children with ADHD often blurt out comments before their brain has even registered the idea of talking. In the classroom, this can lead to a lot of frustration for the child, his peers and his teachers.


The BlurtLine attempts to give children with ADHD a handle on their impulsive speech by notifying them when they are about to blurt. It does so by monitoring the breathing of a child, which is an indicator of impulsive speech.


The BlurtLine was developed as a research project at the Technical University of Eindhoven. The aim of this project was to develop tools for teaching by a research through design approach.
