Presentation devices are tools used to display information visually during presentations. Common examples include projectors, which project images or videos onto a screen, and interactive whiteboards, which allow users to manipulate content directly on the display. These devices enhance communication by making it easier for audiences to understand complex information. Another important type of presentation device is the clicker, or remote control, which allows presenters to advance slides without being tethered to their computer. Additionally, smartphones and tablets can be used to present content wirelessly, providing flexibility and convenience in various settings.
