In this TED Talk, Professor Martin J. Eppler explores how to elevate visual presentations to foster creativity, collaboration, and effective communication. He challenges the trend of slick, "museum-like" presentations and instead encourages the use of "ugly" visuals, such as sketches and doodles, to promote teamwork. Emphasizing the power of visual metaphors, he suggests incorporating simple, relatable images to clarify complex ideas and make presentations more memorable. Lastly, he introduces the concept of "visual variation," where slightly altering visuals can spark deeper discussion and enhance understanding.
