Students and audience do actually pay more attention to your class or presentation. It's a great tool for teaching home-schooling. For whatever reason, kids think you are watching them. Very effective with WebEx screen sharing. Conserves bandwidth for audio.
This technology makes a dull powerpoint presentation come alive. The user interface allows for moving your image around to different spots on the screen to maximise effect. I plan to use this for webinars and to give a personalized pitch for our Venture Capital search. To be able to communicate one's enthusiasm for the subject matter through body language instead of just with voice inflection gives the presentation a dynamic feel.
