Computer-generated graphical presentations: use of multimedia to enhance communication.
Personal computers may be used to create, store, and deliver graphical presentations. With computer-generated combinations of the five media (text, images, sound, video, and animation)--that is, multimedia presentations--the effectiveness of message delivery can be greatly increased. The basic tools are (1) a personal computer; (2) presentation software; and (3) a projector to enlarge the monitor images for audience viewing. Use of this new method has grown rapidly in the business-conference world, but has yet to gain widespread acceptance at medical meetings. We review herein the rationale for multimedia presentations in medicine (vis-à-vis traditional slide shows) as an improved means for increasing audience attention, comprehension, and retention. The evolution of multimedia is traced from earliest times to the present. The steps involved in making a multimedia presentation are summarized, emphasizing advances in technology that bring the new method within practical reach of busy physicians. Specific attention is given to software, digital image processing, storage devices, and delivery methods. Our development of a urology multimedia presentation--delivered May 4, 1996, before the Society for Urology and Engineering and now Internet-accessible at http://www.usrf.org--was the impetus for this work.
