Artificial Intelligence is about the replication of human intelligence in machines that are programmed to think as humans and imitate their actions. A human characteristic is the one of decoding the facial expression related to a determined emotion of other humans and this is necessary for the coexistence. In order to reproduce this peculiarity, the studies aimed to create empathetic machines able to recognize the facial expression of the facing human. This technique called Facial Expression Recognition (FER), is fundamental to a robot to understand the feelings in order to react consequently considering the perceived emotion. The interest towards this technique is increasing rapidly, so the purpose of the 3D Lab of Polytechnic of Turin was to create a database made up human spontaneous emotions collected with an experiment in collaboration with the Pontif´ıcia Universidade Cat´olica do Rio de Janeiro.
