Let’s improve on the emotion recognition from a previous article about FisherFace Classifiers. We will be using facial landmarks and a machine learning algorithm, and see how well we can predict emotions in different individuals, rather than on a single individual like in another article about the emotion recognising music player.

RunningImage8

Let’s make a device to measure and log some interesting sports/running data (like gps position, speed, heart rate, number of steps, etc.). We will also push this data to a webserver and plot it, so that your friends can see your current position and view your stats live.
