I spend a lot of time studying rhetoric and the logic of giving a persuasive presentation. Many of my posts on this website deal with the content and organization of a good speech. I’ve written a bit about body language (here) and I can usually help a speaker feel comfortable in front of an audience. (That’s well over half the battle).
Today, however, let’s learn from the experts: Barack Obama and Mitt Romney. The New York Times has an excellent article, including interactive graphics, on gestures and movements that these orators make to emphasize points and to gain agreement with the audience. They both appear to be masters of the art — so take a peek here.
