For shelter managers

There is high possibility that shelter managers are also impacted by the disaster and the turnover at the position could be really speedy. In order to manage the shelter smoothly, this system aims to be a communication system which everyone can use easily.

For the people impacted by the disaster

This system aims to be a system that everyone impacted by the disaster can communicate via various ways and get rescue and information without difference between people who has IT literacy and people who don't have.

How I built it

Challenges I ran into

・In order to get ready for the situation of hard phone connection, added voice mail function and then recorded voice mails are changed into texts to analyze their sentiment to help receipts judgement.

・In order to get ready for the situation of hard network connection, decided to store the information not only on the Bluemix but also on the FlashAir.

・Notice from iBeacon server can be sent without starting the application.

Accomplishments that I'm proud of

Though this system is focused on the shelter managers to use at this time, this application is also designed for easy and immediate use of everyone(ex.: volunteer team, back-end team) without make limitation for any scale of teams and groups.

What's next for InstantCall
