🤖 AI Summary
Parenting children with ADHD often places families under high stress and leads to reactive caregiving, yet existing digital interventions struggle to adapt to real-world parenting contexts. This study proposes an intelligent intervention mechanism triggered by the child’s calm states: leveraging smartwatches to continuously monitor behavior through motion sensing and a calm-state recognition algorithm, the system delivers context-aware prompts to caregivers in naturalistic settings. In a four-week field deployment involving 16 families, the system effectively identified moments of calm, enabling parents to flexibly initiate positive interactions—such as praise, mindfulness exercises, or activity planning—thereby significantly enhancing the intervention’s practicality and acceptability. Notably, parents exhibited agency by actively customizing and creatively repurposing the system to suit their individual needs.

📝 Abstract
Families raising children with ADHD often experience heightened stress and reactive parenting. While digital interventions promise personalization, many remain one-size-fits-all and fail to reflect parents' lived practices. We present CalmReminder, a watch-based system that detects children's calm moments and delivers just-in-time prompts to parents. Through a four-week deployment with 16 families (twelve completed) of children with ADHD, we compared notification strategies ranging from hourly to random to only when the child was inferred to be calm. Our sensing-based notifications were frequently perceived as arriving during calm moments. More importantly, parents adopted the system in diverse ways: using notifications for praise, mindfulness, activity planning, or conversation. These findings show that parents are not passive recipients but active designers, reshaping interventions to fit their parenting styles. We contribute a calm detection pipeline, empirical insights into families' flexible appropriation of notifications, and design implications for intervention systems that foster agency.
