Fluent Design is a user interface design system developed by Microsoft to create visually engaging and adaptive applications. Introduced in 2017, it focuses on five key elements: light, depth, motion, material, and scale. Fluent Design aims to provide a seamless and immersive experience across devices by using smooth transitions, subtle animations, and layered effects. While not a cybersecurity framework, Fluent Design can influence security by enhancing user awareness of system prompts and alerts through visual cues. Its adaptability helps ensure accessibility and consistency, which can indirectly support secure user interactions by reducing confusion and potential user errors.
