"Presentation Zen" is a design philosophy created by Garr Reynolds that emphasizes simplicity and clarity in presentations. It encourages presenters to focus on their message and engage their audience through visual storytelling rather than overwhelming them with text-heavy slides. The approach promotes the use of images, minimal text, and a clean layout to enhance understanding and retention. The core principles of "Presentation Zen" include the importance of preparation, the use of visuals to support the narrative, and the need for a calm and confident delivery. By adopting these principles, presenters can create more impactful and memorable presentations that resonate with their audience.
