The visual characteristic on Apple’s mobile operating system that creates a perception of depth when viewing the home screen or lock screen is achieved through subtle parallax motion. Elements, such as icons and alerts, appear to float above the wallpaper. For example, as the device is tilted, the wallpaper subtly shifts behind the icons, providing a dynamic, layered visual experience.
This feature enhances the aesthetic appeal of the user interface and contributes to a more immersive experience. Its implementation reflects a design philosophy focused on creating visually engaging and intuitive user interactions. Initially introduced as a refinement to the visual presentation of the operating system, it has become a standard expectation for many users.
