39 15.3 Media to Use for Presentation Aids

Computer-Based Media

In most careers in business, industry, and other professions for which students are preparing themselves, computer-based presentation aids are the norm today. Whether the context is a weekly department meeting in a small conference room or an annual convention in a huge amphitheater, speakers are expected to be comfortable with using PowerPoint or other similar software to create and display presentation aids.

If your public speaking course meets in a smart classroom, you have probably had the opportunity to see the computer system in action. Many such systems today are nimble and easy to use. Still, “easy” is a relative term. Don’t take for granted someone else’s advice that “it’s really self-explanatory”—instead, make sure to practice ahead of time. It is also wise to be prepared for technical problems, which can happen to even the most sophisticated computer users. When Steve Jobs, CEO of Apple and cofounder of Pixar, introduced a new iPhone 4 in June, 2010, his own visual presentation froze (Macworld, 2010). The irony of a high-tech guru’s technology not working at a public presentation did not escape the notice of news organizations.

The world was first introduced to computer presentations back in the 1970s, but these software packages were expensive and needed highly trained technicians to operate the programs. Today, there are a number of presentation software programs that are free or relatively inexpensive and that can be learned quickly by nonspecialists. Table 15.1 “Presentation Software Packages” lists several of these.

In addition to becoming more readily accessible, presentation software has become more flexible over the years. As recently as the mid-2000s, critics such as the eminent graphic expert and NASA consultant Edward Tufte charged that PowerPoint’s tendency to force the user to put a certain number of bullet points on each slide in a certain format was a serious threat to the accurate presentation of data. As Tufte put it, “the rigid slide-by-slide hierarchies, indifferent to content, slice and dice the evidence into arbitrary compartments, producing an anti-narrative with choppy continuity” (Tufte, 2005). Tufte argues that poor decision making, such as was involved with the 2003 space shuttle Columbia disaster, may have been related to the shortcomings of such presentation aids in NASA meetings. While more recent versions of PowerPoint and similar programs allow much more creative freedom in designing slides, this freedom comes with a responsibility—the user needs to take responsibility for using the technology to support the speech and not get carried away with the many special effects the software is capable of producing.

What this boils down to is observing the universal principles of good design, which include unity, emphasis or focal point, scale and proportion, balance, and rhythm (Lauer & Pentak, 2000). As we’ve mentioned earlier, it’s generally best to use a single font for the text on your visuals so that they look like a unified set. In terms of scale or proportion, it is essential to make sure the information is large enough for the audience to see; and since the display size may vary according to the monitor you are using, this is another reason for practicing in advance with the equipment you intend to use. The rhythm of your slide display should be reasonably consistent—you would not want to display a dozen different slides in the first minute of a five-minute presentation and then display only one slide per minute for the rest of the speech.

In addition to presentation software such as PowerPoint, speakers sometimes have access to interactive computer-based presentation aids. These are often called “clickers”—handheld units that audience members hold and that are connected to a monitor to which the speaker has access. These interactive aids are useful for tracking audience responses to questions, and they have the advantage over asking for a show of hands in that they can be anonymous. A number of instructors in various courses use “clickers” in their classrooms.

Using computer-based aids in a speech brings up a few logistical considerations. In some venues, you may need to stand behind a high-tech console to operate the computer. You need to be aware that this will physically isolate you from the audience you with whom you are trying to establish a relationship in your speech. When you stand behind presentation equipment, you may feel really comfortable, but you end up limiting your nonverbal interaction with your audience.

If your classroom is not equipped with a computer and you want to use presentation software media in your speech, you may of course bring your computer, or you may be able to schedule the delivery of a computer cart to your classroom. In either case, check with your instructor about the advance preparations that will be needed. At some schools, there are very few computer carts, so it is important to reserve one well in advance. You will also want to see if you can gain access to one ahead of time to practice and familiarize yourself with the necessary passwords and commands to make your slides run properly. On the day of your speech, be sure to arrive early enough to test out the equipment before class begins.

Audiovisual Media

Although audio and video clips are often computer-based, they can be (and, in past decades, always were) used without a computer.

Audio presentation aids are useful for illustrating musical themes. For instance, if you’re speaking about how the Polish composer Frederick Chopin was inspired by the sounds of nature, you can convey that meaning only through playing an example. If you have a smart classroom, you may be able to use it to play an MP3. Alternatively, you may need to bring your music player. In that case, be sure the speakers in the room are up to the job. The people in the back of the room must be able to hear it, and the speakers must not sound distorted when you turn the volume up.

Video that clarifies, explains, amplifies, emphasizes, or illustrates a key concept in your speech is appropriate, as long as you do not rely on it to do your presentation for you. There are several things you must do. First, identify a specific section of video that delivers meaning. Second, “cue up” the video so that you can just pop it into the player, and it will begin at the right place. Third, tell your audience where the footage comes from. You can tell your audience, for instance, that you are showing them an example from the 1985 BBC documentary titled “In Search of the Trojan War.” Fourth, tell your audience why you’re showing the footage. For instance, you can tell them, “This is an example of storytelling in the Bardic tradition.” You can interrupt or mute the video to make a comment about it, but your total footage should not use more than 20 percent of the time for your speech.

Low-Tech Media

In some speaking situations, of course, computer technology is not available. Even if you have ready access to technology, there will be contexts where computer-based presentation aids are unnecessary or even counterproductive. And in still other contexts, computer-based media may be accompanied by low-tech presentation aids. One of the advantages of low-tech media is that they are very predictable. There’s little that can interfere with using them. Additionally, they can be inexpensive to produce. However, unlike digital media, they can be prone to physical damage in the form of smudges, scratches, dents, and rips. It can be difficult to keep them professional looking if you have to carry them through a rainstorm or blizzard, so you will need to take steps to protect them as you transport them to the speech location. Let’s examine some of the low-tech media that you might use with a speech.
