The popular use of computer generated slides for presentations during plastic surgery scientific meetings has opened a fresh chapter in audiovisual techniques. Although the profusion of colours seen during presentations is a visual treat, the information imparted by these slides leaves much to be desired and raises the question of whether such attractive and apparently professionally made slides are visual aids during such presentations. Presentation slides are displayed for a very short time (10-15 seconds) as compared to slides displayed during a lecture and therefore these presentation slides should have the ability to impart their information very quickly. We conducted a study wherein 36 slides, each having a different colour combination, were displayed to a class of third year medical students who were asked to judge the efficacy of each slide. The attractiveness, clarity and recall of each slide was graded by every student and, with the information obtained, the most effective format and colour combinations to be used while making slides for presentations were established. We conclude that the best format for slides is a plain dark coloured background (blue, purple or green) and a separate, contrasting plain dark coloured title text background (red, green or purple), with white letters for the text and yellow letters for the title.
在整形外科学术会议期间，计算机生成的幻灯片在演示中广泛使用，开启了视听技术的新篇章。尽管演示过程中看到的丰富色彩是一种视觉享受，但这些幻灯片所传达的信息却不尽人意，引发了这样一个问题：在这类演示中，如此吸引人且看似专业制作的幻灯片是否算得上视觉辅助工具。与讲座中展示的幻灯片相比，演示幻灯片的展示时间非常短（10 - 15秒），因此这些演示幻灯片应该具备迅速传达信息的能力。我们进行了一项研究，向一群三年级医学生展示了36张颜色组合各异的幻灯片，并要求他们评判每张幻灯片的效果。每个学生对每张幻灯片的吸引力、清晰度和记忆度进行评分，然后根据获得的信息，确定制作演示幻灯片时最有效的格式和颜色组合。我们得出结论，幻灯片的最佳格式是纯深色背景（蓝色、紫色或绿色）以及单独的、对比鲜明的纯深色标题文本背景（红色、绿色或紫色），文本用白色字母，标题用黄色字母。
