We all have an interest in improving everybody's quality of life, and thought developing a real-time detection system would be an awesome way to spend a weekend.
What it does
Kōan reads the user's brainwaves via a Muse headband and then displays the data, both live and historical, on a solid web-based app. It also provides an SMS alert system to warn users about impending panic attacks based on activity being read, with the capability to get in touch with an emergency contact for help.
How we built it
Developing the entire system with small microservices allowed each person in the group to develop in a language that they were familiar with, as well as learn with others in conjunction.
Challenges we ran into
Dealing with the firehose of data coming out of the Muse headband was a challenge. It produces data points at a rate of 10Hz, for over 10 different metrics, which was all delivered to Firebase. Working with all this data was a challenge, as analyzing all this data for the warning signs of panic attacks was hard.
Accomplishments that we're proud of
We built an app that has significant potential to positively affect people who have suffer from mental issues such as panic attacks, and learned a lot about new technologies in the process.
What we learned
Real time data processing, low-level protocols, how to integrate many microservices.
What's next for Kōan
Kōan is a proof of concept that shows this sort of product is both viable and useful. The next step is to make something like this accessible for everyone.
