Smartwatch system to automatically detect eating and drinking for children and their parents
Evaluating the Validity and Feasibility of a Smartwatch-based Eating Detection System to Passively and Automatically Detect Eating Events in Child-parent Dyads
This project will test whether a smartwatch can automatically detect eating and drinking events for children aged 8–12 and one parent or caregiver.

What this trial studies
Child-parent pairs will wear a smartwatch on their dominant hand during a lab visit where eating and other activities are video-recorded to create a ground truth for eating events. The same pairs will then wear the watch for three days in their normal lives while parents receive brief prompts on their phone to confirm or activate the device. Researchers will compare the smartwatch’s automatic detections to the video-coded times in the lab and to parent responses during the free-living period to measure accuracy and practicality. The study focuses on passive, wrist-based sensing and brief ecological momentary prompts to support data collection without major behavior change.
Who should consider this trial
Good fit: Ideal participants are parents or caregivers aged 18–70 with a child aged 8–12 who can wear a smartwatch during school and at home and who follow a regular eating pattern.
Not a fit: Children who have irregular eating patterns, food restrictions or allergies, or who cannot or refuse to wear the smartwatch or respond to prompts are unlikely to benefit from this approach.
Why it matters
Potential benefit: If successful, this could give researchers and families an easy, passive way to monitor eating patterns and support nutrition-related programs or research.
How similar studies have performed: Prior wrist-worn and smartwatch studies have shown promising but variable accuracy for detecting eating gestures, so this approach is partially validated but still needs refinement.
