It's called an overhead projector and here's its greatest advantage: Unlike the standard PowerPoint presentation in which the speaker has prepared the slides ahead of time, with the overhead projector you can use sheets with previously-prepared material or you can discuss points with the audience and write down or illustrate key points as the ideas evolve!
In other words, the overhead projector enables you to be closer to the concerns and thoughts of the audience. It gives you greater flexibility as a presenter and permits those in the back of a large room to see items that would never be visible on a flip chart.
You might think that the tools for jotting down your thoughts would be expensive. Not so! All that is needed are clear acetate sheets and a grease pencil or a marker. Some overhead projectors even permit you to rig up a roll of acetate so, as your presentation progresses, you simply crank the roll to get clean writing space. This is high tech at its best.
- No more being locked in by PowerPoint slides!
- No more feeling frustrated by an inability to jot down a point that will clearly answer audience members' questions!
- No more worry that the group is distracted by glitz and cute graphics!
- No more expensive PowerPoint projector bulb bills!
