Visual communication is communication through visual aids that can be seen or looked at. It is considered the most effective communication method. Visual aids help audiences understand information by illustrating key points and increasing interest and retention. Common visual communication tools include PowerPoint, pictures, charts, graphs, films, videos, and maps. PowerPoint is a powerful tool when used well to help presenters without relying on notes. Effective PowerPoint presentations use large readable fonts, simple backgrounds, and appropriate animations and transitions to make information visual.
