Now, computer that could figure out whether you are happy or sad

Researchers have built a system that uses the depth-sensing, motion-capture camera in Microsoft's Kinect to determine the emotion that's conveyed by a person's body movements.

Antonio Camurri of the University of Genoa in Italy and team's system uses the Kinect camera to build a stick figure representation of a person that includes information on how their head, torso, hands and shoulders are moving, New Scientist reported.

The software looks for body positions and movements widely recognised in psychology as indicative of certain emotional states.

Camurri is using the system to build games that could help autistic kids to recognise and express emotions through full-body movements.
