Presentation activity
“Whether it is a chart, a graph, a picture or a cartoon, your audience should be able to understand your message just by looking at the images.” T.J.Walker
Visual Aids Visual aids provide several ways to communicate with an audience during a presentation. They can supplement speeches and improve the success rate of the presentation. Prepare them well in advance, edit and proof them, and be sure to keep them neat and clean. Examples of visual aids include posters, videos, photographs and models. Before any presentation, make sure the room will provide or accommodate the necessary equipment. Posters can include charts, graphs, tables or photographs. Charts, graphs and tables can display statistics or other important data; be sure the information is accurate. Videos can be a successful type of visual aid. Be sure all necessary equipment is available in the presentation room Practice beforehand so there will be no hidden issues. Keep video clips short and be sure that everyone in the room will be able to see the screen. Photographs can help demonstrate a point or provide a visual image to the audience of the subject of the presentation. Photographs must be large enough to see from the back of the room. Keep the slideshow short to avoid losing the audience's interest. Models can show the audience a small version of the original plan, such as a model of a building to be constructed. Build it in 3D and place it where everyone will be able to see it. Keep it covered until you are ready to talk about it so the audience will not get distracted by it.
