From Overhead Projectors to Electronic Presentations
In the past, most presentations consisted of transparencies, or clear plastic sheets. Special copying machines or printers were used to print information onto the transparencies. These transparencies were then placed onto an overhead projector, which projected the text and images onto a large screen. This process had various drawbacks. Creating ransparencies could be time-consuming and expensive. Transparencies could be damaged or lost. Large presentations were so bulky that they were difficult to take from place to place. In order to correct mistakes or update information, the presenter needed to make the change and then recopy or reprint the transparency. During a presentation, the presenter needed to remain beside the overhead projector to change transparencies, preventing him or her from circulating around the audience.
Presentation applications such as Microsoft PowerPoint resolve all the shortcomings of transparencies. PowerPoint allows the user to design electronic slides that do not need to be transferred to transparencies. With the right equipment, all a presenter needs to do is insert the disk or CD on which the presentation is saved into a computer to view the presentation. It is not necessary to carry around a load of transparencies that are bulky, or easily damaged or lost. Slides with errors and information that needs to be updated are easy to edit on a computer. The presenter can activate an automatic timing feature that advances to the next slide automatically so that he or she can circulate around the audience. In addition, owerPoint includes several tools to create charts, graphics, and animation to impress an audience. It is no wonder that PowerPoint has become so popular and widely used.
