If you display it while you are explaining what coral actually is, or describing the kinds of fish that feed on a reef, the map will not serve as a useful visual aid-in fact, it’s likely to be a distraction. For example, if you are speaking about coral reefs and one of your supporting points is about the location of the world’s major reefs, it would make sense to display a map of these reefs while you’re talking about location. Moreover, presentation aids must be used at the time when you are presenting the specific ideas related to the aid. The key is that each presentation aid must directly express an idea in your speech. Other visual artifacts are more likely to deliver information more directly relevant to the speech-a diagram of the interior of Ford’s Theater where Lincoln was assassinated, a facsimile of the messy and much-edited Gettysburg Address, or a photograph of the Lincoln family, for example. It is understandable that someone presenting a speech about Abraham Lincoln might want to include a photograph of him, but because everyone already knows what Lincoln looked like, the picture would not contribute much to the message unless, perhaps, the message was specifically about the changes in Lincoln’s appearance during his time in office. However, all presentation aids have one thing in common: To be effective, each presentation aid a speaker uses must be a direct, uncluttered example of a specific element of the speech. Finally, presentation aids can be three-dimensional objects, animals, and people they can also change over a period of time, as in the case of a how-to demonstration.Īs you can see, the range of possible presentation aids is almost unlimited. A speaker may also use fragrance samples or food samples as olfactory (sense of smell) or gustatory (sense of taste) aids. Audible aids include musical excerpts, audio speech excerpts, and sound effects. The type of presentation aids that speakers most typically make use of are visual aids: pictures, diagrams, charts and graphs, maps, and the like.
Presentation aids are the resources beyond the speech words and delivery that a speaker uses to enhance the message conveyed to the audience. But the speaking event can be greatly enriched by appeals to the other senses. They more or less ignore the other senses except to avoid visual distractions by dressing and presenting themselves in an appropriate manner. In some speaking situations, the speaker appeals only to the sense of hearing. Because you are speaking “live and in person,” your audience members will experience your speech through all five of their senses: hearing, vision, smell, taste, and touch. When you give a speech, you are presenting much more than just a collection of words and ideas.
