We frequently use analogies and anecdotes in casual conversation to help clarify our ideas, so they are especially helpful in presentations. If you have a large audience with different educational or cultural backgrounds, take care when choosing appropriate metaphors or similes.
To interact with your audience, present polling questions. Audience members can submit their individual or team responses using handheld devices read by a PowerPoint add-in program. The audience immediately sees a bar chart that displays the response results. If you would like to know more about audience response systems, visit one of the many Web sites devoted to them, for example, www.audienceresponse.com or www.turningtechnologies.com.
Holding note cards during the presentation allows you to quickly glance at your notes without turning away from the audience. It is important to write only your main points on your note cards; if they contain your word-for-word script, you may be tempted to read your presentation from them. You may also find it helpful to write down any facts and figures that are difficult to memorize completely.
