Yours is one of the most impactful videos on listening- especially face to face listening I have come across. I'd like to add a few points about eye contact: 1. Do not stare 2. Look between the forehead to base of nose 3. Not only does eye contact show you are interested, but it keeps others engaged and responsible to listen to you. This is especially true in a one-to-many interaction like a team meeting or a presentation 4. When possible, arrange a meeting space in a circular form, with only one line of chairs, so no one is hiding behind anyone for effective eye contact in meetings, trainings, and presentations.
The idea that 93 percent of communication is nonverbal is simply erroneous. It's an urban myth. And it's not based "on a lot of studies," but merely one study involving 37 female psychology majors. See David Lapakko, "Three Cheers for Language: A Closer Examination of a Widely Cited Study of Nonverbal Communication," Communication Education (1997), 46, 63-67.
