'nonprint message' is a message that you send to an audience
without using any printed words.
When you are giving a speech or presentation and you have
a loss for words, instead of saying "um" or "Uh",
pause in silence. Another way to use a silent period is to
emphasize a point or subject.
use facial expressions to get your point across to the audience.
For example, if your subject is happy, put on a smile! If
the subject is angry, frown. A facial expression can tell
the audience just what emotion you are conveying.
Movement is another important key in conveying nonprint messages.
One way to use movements is to have ample hand motions included
in your presentations. You should use movements to emphasize
points and/or subjects.
Gestures are basically the same thing as hand motions, but
they are more coordinated with the presentation.
