The purpose of these devices it to catch the attention by making use of one more sense, the sense of sight, besides the sense of hearing.

Much depends of course on the quality of the orator. The best ones capture the audience attention seemingly without any effort and keep the listeners subjugated to the flow of their discourse. This kind of orator may not need projections. But for the great majority of speakers, who are called to present a project or a product, a visual projection may illustrate the subtle points much more easily than by words alone. It may be the list of the main points of the presentation or some graphic illustrating trends or totals, itemized accounts or forecasts, in short a tool for conveying the important meanings of the assertions exposed.
