How did CNN determine the Live audience reaction to the second during the presidential debate?

As you know there was this blue/red/green line going up and down during the 2008 debate that went on yesterday (sept 26,2008). How did they get the data to determine where that little line was suppose to go?How did CNN determine the Live audience reaction to the second during the presidential debate?
CNN has chosen 3 audience members to give their reactions to CNN by giving them through a pulse machine. This is possible by seeing their pulse and looking at how it rises and lowers based on the questions asked. Also, those same people have a handheld device where they press 1 of three buttons meaning plus a little, minus a little, or back to neutral.( Used after each question.)

Hope this helps.
