This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers at Northwestern University are developing and testing a wearable device—a small camera worn around your neck—to better understand how people eat in their everyday lives. The device captures images of what you're eating but includes privacy protections like blurring or cartoon filters to keep your face and surroundings private. This study will help researchers see whether this technology can reliably track eating behavior while respecting your privacy.
Current methods of tracking what people eat rely on memory and written records, which are often inaccurate. This new wearable technology could provide a more objective, real-time way to understand eating patterns—which could eventually help with nutrition research and diet-related health problems.

You'll visit the lab once for training on how to use the device, then wear it during four separate one-week periods at home while going about your normal routine. During each active week, you'll keep a food and drink diary and receive unscheduled phone calls from a dietitian to discuss your eating. Between active weeks, you'll have a break week with no study tasks. The device will use different privacy filters (blur, edge effect, or cartoon style) during different weeks so researchers can test which works best, and you'll see examples before each week starts. At the end, you'll return the device and share feedback about how it worked and how you felt about the privacy features.
