What are three problems that can occur with visual aids?

Three common problems with visual aids include overcrowding, which can overwhelm the audience with too much information; poor design, leading to confusion or distraction rather than clarity; and technical issues, such as equipment failure or compatibility problems, which can disrupt the flow of a presentation. Additionally, if the visuals are not aligned with the spoken content, they can create misunderstandings. Effective preparation and design can mitigate these issues.
