Aid for subconscious habits

Inspiration

Many people have the habit of rubbing eyes, scratching, pulling hair etc., subconsciously. We wanted to help people overcome such habits by making them aware.

What it does

It is trained to recognise certain gestures and alert the person.

How we built it

We built a prototype of this device using an Arduino which acquires motion information from an accelerometer and sends it to a PC via Bluetooth. In the PC, we used ESP software which makes use of gesture recognition toolkit and trained the system to recognise the desired gesture. Once trained, if the user performs that gesture, the arduino triggers a buzzer.

Challenges we ran into

We initially tried using signal processing algorithms on the Arduino which was inaccurate. So, we moved to machine learning using ESP on PC.

We had to ensure reliable data over the bluetooth channel by configuring the proper sampling and baud rates.

We had to configure the ESP software and train the system for good performance.

Also, Arduino MKR1000 was a new platform with lack of documentation.

Accomplishments that we're proud of

We are proud that we were able to make a functional prototype in a single day.

What we learned

To explore and solve a challenge with limited time and resources. We are excited to be able to apply machine learning for the first time in our project.
