FaceTracker
Together with Guido I have been investigating the FaceTracker library by Jason Saragih (http://web.mac.com/jsaragih/Jasons_Homepage/Home.html) using the openFrameworks addon ofxFaceTracker developed by Kyle McDonald (https://github.com/kylemcdonald/ofxFaceTracker).
Project
The project we build after making the basic plots of facial expressions is inspired by the AntiRSI app, that pops up with a timebar for you to take a break from working and looking at your screen (http://tech.inhelsinki.nl/antirsi/).
The idea is your face is being tracked on smiling. If you sit working behind your laptop and did not smile the last 15 minutes than a funny video will pop up that will make you smile for a moment. So you can continue working with some positive happy impulse.
