Posture Corrector

Inspiration

Good posture is essential when working at the computer. Nowadays it is common to sit in front of screens for a long time without realizing necks bent and strain accumulates. Our project aims to address this issue by providing effective response to bad postures.

What it does

A posture detector responds to unnatural angle of displacement of the bending over a period of time. The bending of the sensor would result in a signal eventually reflected on a red LED, which lights up temporarily and works as a warning sign to inform the user that their posture needs adjustment to ease their neck strain or muscle fatigue.

How we built it

front-end: flex-bending sensor (attach to muscles, necks, etc)
intermediate circuit: LED, 7-seg display
back-end: Arduino UNO, connected with PC The extent of bending would result in different voltage signals, which are processed and converted to digital logic through Arduino, eventually let output LED emit light when reaching the threshold value we set.

Challenges we ran into

Series of problems happened along the way, from beginning to the end. Op Amp circuit completed to provide linear variance, but eventually abandoned due to failure to provide required voltage supply; challenges in configuring the circuit to fulfill the input voltage range; the flex-bending sensor seems not working as sensitive as it should be; and physical support using 3D print takes much longer than expected...

Accomplishments that we're proud of

First hackathon ever for our members! Proud of ourselves to make the first step. And we distribute the work in a perfect way which aligned with each member's major and strengths of skills: some good at CAD modelling, some good at building up the circuit, others good at coding... The most important thing is, what we have learned in our textbook and classes had finally comes to practice, and the feeling to create something by our own hands is amazing!
