MIT Jerk-o-Meter etc.
Groupmedia research:
Extract four basic signals from speech dialogues, possible inside a mobile
phone. Use them to provide feedback on the quality of a conversation (Am
I a jerk?) or to predict whether people feel attracted or are going to
close a contract.
Audio and Mood
Basic idea of a number of works: play back or create the right sound or
music for the user's current mood or to change the user's current mood
in a determined way. This is a problem of affective computing. These are
the basic issues:
-
What is emotion? What is mood? Can we define them by numbers, for instance
by reducing them to a blend of basic emotions?
-
How can we measure emotion? Typical inputs: heart rate, breath rate, skin
resistance, skin temperature. Need signal processing and pattern classification
to go from these inputs to emotions.
-
How can we determine the mood of a piece of music? On may ask listeners,
experts, try to compute the mood from the musical score or from the wave
data.
