Virtual Camera Zoom for Seamless Game Interface Switching

The patent applies the dynamics principle by transforming the static, rigid interface switching mode into a dynamic, flexible one. Specifically, it introduces camera zooming and rotation animations that dynamically adjust the viewing angle and focal length during interface transitions. The camera dynamically moves from a first position to a second position, and the focal length dynamically changes during the transition, creating a smooth, continuous visual effect that maintains user flow while enabling interface switching.

The patent uses the camera as an intermediary element between the user and the interface content. Instead of directly switching between interfaces, the camera serves as a mediator that gradually transforms the view through zooming and rotation. This intermediary mechanism softens the transition by providing a visual bridge between different interface states, reducing the abruptness of switching while maintaining simplicity in the underlying interface structure.

The patent applies universality by making the virtual camera serve multiple functions simultaneously. The camera is not only used for displaying game content but also acts as a transition mechanism for interface switching. By combining the display function and the transition animation function into a single camera system, the patent avoids adding separate complex transition mechanisms, thereby improving user immersion without proportionally increasing device complexity.

The patent utilizes parameter changes by modifying camera parameters (position, focal length, rotation angle) during interface transitions. Instead of creating complex new components, the system achieves smooth transitions by dynamically adjusting existing camera parameters. The focal length changes from a first value to a second value, and the rotation angle changes from a first angle to a second angle, creating immersive effects through parameter modulation rather than structural complexity.
