Goal: Stop slouching.
How it works: A sensor worn around your lower back vibrates when you slouch.
Real-life road test: Whenever I catch a glimpse of myself in a mirror while sitting, I'm horrified by how hunched over I am. Sitting up straight wouldn't be so hard if only I could remember to do it. However, once I strapped on the sensor, the constant vibrations were impossible to ignore! A color-coded stick figure appeared on my phone so I could see how I looked. When the little guy was green, I was good; when he was orange, I knew I needed to readjust.
Good idea or bad idea: Good. The sensor hid easily under my clothes, and while I mostly wore it at work, I naturally started sitting up straighter even when I didn't have it on.
