Developed: 7th-8th March 2015
Tools used: Java, Android SDK
For the 2015 appathon, a group of 5 of us decided to make Seemoji, an Android keyboard app. Rather than having to scroll all the way through a long list of emojii when you want to insert one into a message, Seemoji uses your phone's front camera to detect your facial expression and offer up the appropriate emoji. Or at least that was the plan.
Seemoji exists largely as a proof of concept - we weren't able to get the facial detection fully working during the 26 hours, but it works to some small extent. The app itself works as a background keyboard service, usable from any app.
