DIY slouch detector

A couple of years ago I was afflicted by Frozen shoulder. It was extremely painful. I experienced a loss of sleep for days and wound up in the emergency room. After weeks under a strong opium-based painkiller, I started physical therapy. I was very fortunate to recover quickly and without any side effects.

Nobody knows the origin of Frozen Shoulder. One theory is that it's related to the day-to-day slouch position we often adopt in office environments. And so during physcial therapy, a lot of the excercises focused on straightening the back muscles.

Staying in front of a computer all day I adopted bad posture.

I am the guy on the left. My physical therapist told me that in 20 years my spine would lock itself in that position.

There are a number of papers online about how your posture is important for your health and also important to how people percieve you.

DIY Posture Detection

TinyDuino

To help correct my bad posture, I decided to stack together a few tiny duino devices, into which I loaded a short Arduino code:
TinyDuino

  • TinyShield 16 edge led
  • TinyShield Processor board with battery holder
  • TinyShield Accelerometter

This served as a pretty useful homemade posture coach.

Lumo Lift

A couple of months after I built my own device, the Lumo Lift came out. I've been using it since and I like it a lot. Its one of those few devices that I've tried to fully adopt.
