This document discusses the use of visual aids in public speaking. It identifies different types of visual aids including PowerPoint slides, props, display boards, videos, photos, maps, and charts. The benefits of using visual aids are that they can improve audience understanding and memory retention, serve as notes for the speaker, provide clearer organization, and allow for more eye contact. When creating visual aids, speakers should make sure the aids are large enough to be seen by all and contain simple graphics, fonts, and information. Speakers should also practice with their visual aids and introduce/summarize the content while maintaining eye contact with the audience.
