Swiss Federal Institute of Technology (EPFL) researchers will use social media to track the emotions of people viewing the Winter Olympics in Sochi. The researchers are using social media and online discussion boards to test emotion-recognition software.

To monitor emotions in real time, the researchers developed EmotionWatch, an application that displays the various emotions in the form of a colored pie chart. The virtual watch displays the strongest trends on the screen, and the disk changes color depending on the intensity of the emotion.

This system is based on a wheel of emotions designed by psychology students at the University of Geneva. EPFL researcher Renato Kempter enhanced the wheel by adding the element of color, surrounding the disk with 20 colored dots, each representing a particular emotion. The software identifies keywords and displays the color of the most intense emotion.

"The application must be more than just attractive or fun," says EPFL's Pearl Pu Faltings. "For us scientists, it is important that our system is operational in other competitions and reliable in the recognition of Twitter vocabulary."
