Slides are commonly used in presentations and talks because they provide a visual aid that can help to illustrate and reinforce the speaker’s points. Slides can be used to display text, images, charts, and other types of information, and they can help to make a presentation more engaging and interactive. In contrast, document scrolling involves displaying text or other information on a screen or projection surface, and scrolling through the document as the speaker reads or discusses the information.
Slides have several advantages over document scrolling. First, slides allow the speaker to control the pace and flow of the presentation, and to highlight specific points or pieces of information. This can make the presentation more organized and structured, and can help the audience to follow along and understand the material. Second, slides can add visual interest and variety to the presentation, which can help to keep the audience engaged and attentive. Finally, slides allow the speaker to include a wider range of information and multimedia elements, such as images, videos, and animations, which can make the presentation more dynamic and engaging.
Overall, slides are often used in presentations and talks because they provide a useful and effective way to convey information and engage the audience. While document scrolling can also be a useful tool, slides are often preferred because they offer more flexibility and control over the presentation, and can make the material more accessible and engaging for the audience.
