This study is testing a small, privacy-focused wearable device that you wear around your neck. It records color images of your head and upper body, but no sound. The goal is to see how well this device can monitor your eating behaviors over time. We're looking for adults aged 18 and older who live in the Chicago area, have a BMI of 18.5 or higher, and can speak, read, and write in English. You also need a smartphone and computer. We'll measure how long you wear the device each day over 7 days to see if it's successful. The study is currently unclear about its recruitment status.

Study design

This is an interventional study planning to enroll 72 participants. It tests different ways of blurring images captured by a wearable device, including Blur Obfuscation, Cartoon Obfuscation, Edge Obfuscation, and No Obfuscation.

What's involved

You will visit the lab for consent and device training. Then, you'll wear the device at home for four "active" weeks, keep a food log, and have phone calls with a dietitian. There will be "washout" weeks in between where you don't have study tasks.

Compensation

Not stated in the trial record.

Follow-up

The primary endpoint, daily wear time, is measured at 7 days.
