What this Trial Is About
Researchers are evaluating a smartwatch-based system designed to automatically and passively detect eating and drinking events in child-parent pairs. The study aims to test the accuracy of this system in both controlled laboratory settings and everyday free-living conditions. It focuses on children aged 8 to 12 years and their parents or caregivers, exploring how well the technology works for tracking eating behavior in real life. The study has two main phases. During the first phase in the laboratory, child-parent pairs will wear the smartwatch on their dominant hand while performing various eating and non-eating activities, all recorded on video for comparison. In the second phase, participants will continue wearing the smartwatch for three days while living their usual daily lives. Parents will receive reminders through personalized Ecological Momentary Assessment (EMA) prompts to activate the smartwatch and report meal and snack times. Participants will be monitored for adherence by tracking how often they wear the smartwatch and respond to EMA prompts. The researchers will assess the accuracy of eating detection during the lab session and evaluate how well participants follow the smartwatch protocol during the free-living period. The total study participation lasts four days, including one day in the lab and three days at home, with safety and feasibility carefully observed throughout.
