As the definitons states, visual aids make your presentations or texts more powerful by displaying words and images to the audience in different formats. In this way the audience's imagination can be triggered, making it focus on the topic and understanding it in a better way. Other examples of visual aids are: photographs, tables, diagrams, charts, key words, or video sequences. Visual aids should be used in the key moments of the presentation to explain things that are hard to say just with words. It is important not to use them in excess as they might be confusing.
