Summary
This study tested a smartwatch app called holly™ that tracks children's emotional arousal levels and sends alerts to parents. Over three weeks, 126 children with strong emotional responses wore the watch while parents used a study phone to see updates and history. The goal was to see if families found the tool useful and easy to use at home, school, and in the community, and to gather early data on whether it improves quality of life.
