Helping the audience understand how the information
you're presenting relates to their personal, academic,
or professional lives is a good way to make sure
they're engaged in the presentation.
Using music, audience participation, humor, or other
things can also be ways to keep an audience
engaged.
However, it's important to make sure these special
elements are appropriate for the audience. For
example, using loud music during a workplace
presentation would be unprofessional.
Making sure you make eye contact with the audience
as you present is another important part of giving a
presentation.
Looking all around the room as you present, instead of
making eye contact with just one person, helps
engage the entire audience.
