The three key principles of exhibition design are cohesion, engagement, and accessibility. Cohesion refers to the seamless integration of various elements within the exhibition space, including visuals, messaging, and interactive components, to create a unified and harmonious experience for visitors. Engagement involves designing exhibits that captivate and involve attendees through interactive displays, immersive environments, or compelling storytelling techniques, fostering meaningful interactions and leaving a lasting impression. Accessibility ensures that the exhibition is inclusive and easy to navigate for all visitors, regardless of their physical abilities, language proficiency, or cultural backgrounds, by providing clear signage, ample space for movement, and accommodations for diverse needs. By adhering to these principles, exhibition designers can create impactful and memorable experiences that effectively communicate their intended message and resonate with audiences.
