We created a posture monitor because of our interest in health and fitness. We designed our circuit using the PIC32 microcontroller, flex sensor, vibration motor and TFT LCD. We attached the flex sensor and vibration motor to the lower back of a compression shirt that is worn by the user. The microcontroller uses the output of the sensor to determine if the user is in poor posture and sends a signal via the vibration motor accordingly. We also included an interactive display that allows the user to calibrate the sensor according to his or her good posture, gives the user a visual indication of when the user is in bad posture as well as keeps track of how many times the user slouches. Our goal is to design an easy-to-use product for those who want to better their posture during everyday tasks, such as working at a desk or sitting in class.
I'm Rohit Jha. I'm Amanda Pustis. I'm Marissa Irani.
And we created Posture Corrector, a posture measuring device to determine correct posture.
And as our slogan is, we've got your back.
So show me the sensor there.
So we have a 4.5 inch plus sensor from SparkFun.
We sewed and stapled the two ends to a piece of felt right here,
which is velcroed onto the shirt so that the user can remove it off the shirt if they don't want it on there.
And right above it, we have a single vibration motor.
And the reason why we included a vibration motor was you can look at a screen and it can tell you that you're in a poor posture state.
But if you have a physical indicator, it's much better.
And it provides a sort of annoying factor that immediately makes the user want to correct themselves into a correct posture.
And it's in the appropriate place to give you the indication.
To find the most annoying place on the back.
And did they do that?
They succeeded.
So set it up now. There's a calibrate mode, right?
This is the home screen.
And then, so you have a single button.
And we click through twice.
So she just sits up for a certain number of times, the bar will say.
Okay, now hold that posture. So you're sitting up in a straight configuration.
And the bar has now said it's completely full, so it's saying it's been calibrated.
So now we can go to the next screen.
Which is a body outline.
And the green bar is the sensor.
Okay, and now as you slump, it turns red.
Okay, now I'm going to try and see if I can...
Slumped.
And straight.
And at the same...
Currently when the red bar occurs, the vibration sensor on her back is fully calibrated.
Okay, now do a slump. Yeah, that's perfect.
Do a slump and straight.
Slump and straight.
Okay, now I'm going to get down here where I can hear the motor.
I can hear the motor. I hope the camera can't.
So then the other thing we have is a screen that counts the number of times that the red bar occurred.
We call it back breakers in our system.
And so you're flexing your back and the count is increasing.
And then with a button push...
You can toggle between the two screens.
Kind of like we would model it after a Fitbit.
So you can toggle between stat menus.
So between the body image and the number of back breakers.
You can toggle between them depending on which one you want to see.
Okay, and the goal in the final version of this would be to have it miniaturized on a wrist.
So kind of like a Fitbit, so a wearable device.
Correct.
And potentially making this wireless so that like a Fitbit you can put the stats on the computer or on the watch.
So you can use it while you're driving or doing other various tasks.
Or you can make a phone app.
You don't have necessarily the option of wiring.
Or a phone app.
A phone app, yeah.
So then they could have the Bluetooth on the back and a phone app.
So you can similarly get it on the go when you're exercising.
Similar to a Fitbit, they have the app and then also the wearable device.
Cool.
Okay.
Thank you.
