Evaluating the Validity and Feasibility of a Smartwatch-based Eating Detection System to Passively and Automatically Detect Eating Events in Child-parent Dyads
Purpose
This study will test the validity and feasibility of an smartwatch-based system to detect eating and drinking events in both laboratory and free-living conditions.

Detailed Description
The study will: 1) determine whether the smartwatch-based system accurately detects eating events in child-parent dyads in controlled settings and 2) evaluate the feasibility and practicality of passively detecting eating events in child-parent dyads over 3 days in free-living settings. The study will include two phases. During the laboratory visit, child-parent dyads will wear the smartwatch on their dominant hand and perform activities including eating gestures. These activities will be recorded with a video camera, and the videos will be coded for the ground truth times of eating. In the second phase of the study, child-parent dyads will continue wearing the smartwatch for 3 more days in free-living conditions. In the free-living period, parents will receive personalized Ecological Momentary Assessment (EMA) prompts reminding them to activate the smartwatch.
