Interviews
Current Product User 1
“Incessant vibrations and sticky application to skin was annoying. I ultimately wanted to take the device off or turn the vibrations off which I think defeats the purpose of the device.”
Current Product User 2
There is only a single point of reference and calibration is based on what I think is correct posture and how do I know I am right? I wish these kinds of products were more accurate.”
Doctor
“No direction on how to fix posture other than sitting up straighter. If there was a way to connect to exercises that would be prescribed by physical therapists to the state of my posture.”

Ideation
Our team decided to apply multi-sensors to fix the problem of accurately detecting the shape of the spine. After that, we start our ideation from how to mount the sensors on our body.
2. Install the velcro in the housing
1. Velcro mounts the sensors
3. Shape and structure definition
Final Design
Stretchy material to fit most of people
Place four sensors to reach precise shape of spine
