I spent the first year of my master's program with EIT Digital at Aalto University in Finland. During a course called "Design Project", I was part of a group that developed a language learning app for immigrants that makes use of simplified news programs provided by YLE, the Finnish public broadcaster.
This project was started entirely from scratch; Before we started, not even the target audience had been defined. The course focused on user centered product and service design, which means we spent a lot of time talking to potential future users. In our case, those users were recent immigrants who came to Finland. They clearly have a set of problems to overcome in daily life, and "Uutiskylpy" (Finnish for "news bath") tries to alleviate some of those problems.
The app works by showing the user parts of a simplified news broadcast. It shows subtitles, and pauses after every sentence. The user can tap on words if they don't understand them, or they can have the app provide a full translation of the sentence if they are struggling too much. The translations that are provided are enhanced; They provide information about the grammar of single words, and show the user which word means what when they are looking at a full translation. Below, you can watch a video of the prototype application that I developed for this course. It was built using Cordova.
