Our First Problem:

Problem Statement: 

Foreigners cannot understand signs written in national language.

Hopefully that is eight words or less....

Our Solution:

We thought of creating a mobile app that can use the camera to detect the text written in signs and notices and then translate them online.

Analyzing the solution:

After presenting our solution, we came to a few speed bumps. We came across the problem of how many foreigners actually owned smartphones and the requirement of a data plan.

It was suggested to us to use QR code, which would work quite well. A flagship smartphone would not be required to use QR Codes. 

Also having a built in translator would reduce the requirement of the internet. Only if the built in translator cannot sufficiently translate a sign, then it can connect to the internet.
