Visual aids help a speaker reinforce speech content visually, which helps amplify the speaker’s message. They can be used to present any of the types of supporting materials discussed previously. Speakers rely heavily on an audience’s ability to learn by listening, which may not always be successful if audience members are visual or experiential learners. Even if audience members are good listeners, information overload or external or internal noise can be barriers to a speaker achieving his or her speech goals. Therefore skillfully incorporating visual aids into a speech has many potential benefits:
- Helping your audience remember information because it is presented orally and visually
- Helping your audience understand information because it is made more digestible through diagrams, charts, and so on
- Helping your audience see something in action by demonstrating with an object, showing a video, and so on
- Engaging your audience by making your delivery more dynamic through demonstration, gesturing, and so on
There are several types of visual aids, and each has its strengths in terms of the type of information it lends itself to presenting. The types of visual aids we will discuss are objects; chalkboards, whiteboards, and flip charts; posters and handouts; pictures; diagrams; charts; graphs; videos; and presentation software. It’s important to remember that supporting materials presented on visual aids should be properly cited. We will discuss proper incorporation of supporting materials into a speech in Section 9.3 "Organizing". While visual aids can help bring your supporting material to life, they can also add more opportunities for things to go wrong during your speech. Therefore we’ll discuss some tips for effective creation and delivery as we discuss the various types of visual aids.
