What it does

We developed a system that monitors an individuals vitals and is able to report it in real time in an aggregated form to a doctor in a hospital, a construction worker supervisor at a construction site, or even to a sports coach that wants to monitor his players' vitals from the sidelines!


Real-time monitoring and rapid response with preventive medicine is the best form of health care. With the advent of IoT's popularity, we must be able to intelligently utilize the information that they are able to provide us. Population is rapidly increasing every year and we must improve health care proportionally and even further.

How we built it

We made a full-stack approach from hardware to software that we were able to implement data in real-time. – Hardware: Polar sensor to monitor heart-rate-related information through BLE connection to an Android device – Application: Implemented on an Android Device, which transmits the received data periodically to a Database – Web: LAMP web dev stack was used – Database: MySQL and Redis

We were using the following software languages: – Python: to create a rapidly prototyped ecosystem in full stack before implementing over to LAMP – Google Maps API: to display location (x,y) tuple coordinates from the MySQL database (which we would ideally combine with an iBeacon for location updates) – Encryption algorithm API: to transmit data encrypted (since it should be HIPPA compliant) – Javascript, jQuery, HTML5: to display data on the fronted for the real-time heart rate chart monitor for each individual.

Challenges we ran into

– Language barrier: our team consists of 3 students from Keimyung University from South Korea who can speak English very well, however we were able to complete a working prototype that we were able to run through all the way from the hardware sensor. – Medical terminologies that were difficult to translate, since the project is heavily reliant on being able to relate data points to meaningful alerts and such. – Cultural differences between American and South Korean

Accomplishments that we're proud of

The full stack approach from hardware to software was a complete multi-intelligent-IoT-feedback response system, which really was able to work as a prototype given the 3 days we were given. Anyhow, having fun and being positive through the hackathon.

What we learned

Our shortcomings of certain technologies, but we were able to learn as we went. SQL, Python, Redis are some examples of technologies that weren't initially well known in terms of syntax and such but–being that it was a hackathon–we learned it as we went.

What's next for Rapid & Preventative Measures Monitoring System

Further development of security since it must be HIPPA-compliant. Research into other industries this aggregated (real-time) vitals feedback system could be implemented in (e.g. Construction, Sports, etc)
