Because overhead transparencies are the most popular visual aid, the equipment takes a beating. Here are some of the disadvantages of using overhead transparencies:
For an impromptu meeting with colleagues, you can simply hand print or hand draw your transparencies.ĭisadvantages of using overhead transparenciesĪlas, the world isn't perfect. You can also reproduce colorful photographs on a transparency and have good resolution. Color printers and copiers can enhance your message by drawing attention to key features and providing a visually interesting (yet still unobtrusive) background. Sneak glances are no problem with overheads. That's a really important advantage otherwise, part of your mind is constantly trying to remember what's next. Since most speakers handle their own transparencies, they can glance at the label on the next one and see what the next topic is. An added advantage is that you can easily erase your writing later with a damp paper towel (if you're like me, however, you may walk around for a day or so with red or green or blue fingers). With a transparency, you can do that easily. Sometimes you don't want the audience to see a static visual aid (like a ready-made equation) instead, you want to create it, step by step, as the audience watches. No problem: just reach for the appropriate transparency and press ahead. For example, occasionally someone needs an answer now for something you planned to cover later. You can rearrange your presentation on the fly-with the audience staring at you- to meet new needs. If you use cardboard frames around your transparencies, you increase the bulk somewhat, but they're still quite portable. This is no small matter if you travel often. For most presentations, you can easily fit your transparencies in your briefcase with room to spare.

You can also make them yourself, without waiting for a professional staff to produce them for you. This way you can make transparencies quickly, revise them quickly, and revise them often. But instead of copying onto blank paper, copy onto a transparency. Simply prepare your visual aid on paper and then copy it on a copier.
