Why they design liquid glass as new ui?

Liquid Glass is a new design element introduced by Apple to enhance the user interface across its platforms. It is designed to create a more dynamic, expressive, and interactive experience. Here are some key reasons why Liquid Glass was designed as a new UI element:

1. Depth and Vitality: Liquid Glass combines the optical qualities of glass with responsive fluidity, creating a new level of depth and vitality. It refracts content from below, reflects light from around it, and has responsive lensing along its edges, making the UI feel fluid and alive (Platforms State of the Union).

2. Interactivity: Interactivity is at the core of the new design. Liquid Glass visually lifts controls while maintaining a closer relationship to the content beneath, enhancing the interactive experience (Platforms State of the Union).

3. Unified Design Language: Liquid Glass delivers a unified design language across all platforms, seamlessly blending hardware and software. It introduces a more fluid and dynamic interaction experience, marking a new chapter in Apple's visual and interaction design (Meet Liquid Glass).

4. Adaptive and Dynamic: Liquid Glass is designed to be adaptive to its size and environment, ensuring legibility and maintaining clear separation from the content layer. It dynamically morphs to recede in prominence when a user wants to focus on app content, and expands when needed (Meet Liquid Glass).

5. Expressive Material: Inspired by the physicality and richness of vision OS, Liquid Glass is a purely digital material that feels natural and alive. It transforms depending on content or context, bringing more clarity to navigation and controls (Keynote).

Overall, Liquid Glass is designed to enhance the user experience by making the interface more engaging, interactive, and visually appealing, while also providing a consistent design language across Apple's ecosystem.
