Overview
- The peer-reviewed study was published Sept. 17 in npj Digital Medicine by a Northwestern University team.
- Sixty adults with obesity were monitored for two weeks using a necklace sensor, a wristband, a body camera, and an app that captured mood and social context.
- Researchers identified five overeating profiles: take-out feasting, evening restaurant reveling, evening craving, uncontrolled pleasure eating, and stress-driven evening nibbling.
- The HabitSense body camera is a patented Activity-Oriented Camera that uses thermal cues to record only food-related actions to address bystander privacy.
- The NeckSense necklace passively detects real-world eating metrics such as chewing speed, bite count, and hand-to-mouth movements, enabling fine-grained behavioral analysis.
