Empatheticon (2012)
|
An empatheticon is a set of pre-defined motion frames that visualize an emotion, which could be adapted to any given picture. Given that every member has a profile picture, we design empatheticons to present each group member’s emotions by applying motion features to the profile pictures. Empatheticons present the nine music-evoked emotions in Geneva Emotion Music Scale-9. The empatheticons are implemented as a library on Android system, with a specified emotion and a picture as input, and a kinetic animation as output.
By applying the empatheticons in a group music system, users can specify their emotions when listening to a group song. The emotions will display as an animated profile picture of the user, who annotates. These annotations are can last as long as the song itself. Users can change emotions, and thus a song can have different labels at different times. Group members can see the user’s emotions and vice versa in a distributed and asynchronous way. |

Users can indicate their emotions by tilting the phone and placing a white ball on the hole representing the emotion on the plate.
