Spin-Home Idle Screen Application Cycling via Single Key Input

The patent applies multi-functionality by enabling a single key button to serve multiple purposes: it can launch different applications by combining it with different pressing patterns (single press, double press, long press) or by being assigned different functions through software configuration. This allows one physical key to provide access to multiple applications, eliminating the need for separate keys for each application and thus reducing device complexity while maintaining high versatility.

The patent implements dynamics by making the key button's function changeable and adaptive rather than fixed. The same physical key can dynamically switch between different applications or functions based on user interaction patterns or software settings. This dynamic reconfiguration allows the terminal to accommodate multiple applications without requiring additional physical keys, resolving the contradiction between functionality and device complexity.

The patent makes each key button universal by enabling it to access multiple applications through different interaction modes. Instead of having dedicated keys for each application, a single key button can trigger different applications based on pressing duration, combination presses, or software-defined functions. This universal key design maintains ease of operation with minimal buttons while supporting a large number of applications.

The patent changes the operational parameters of the key button to expand its functionality. By varying parameters such as pressing duration, pressing sequence, or combination with other keys, the same physical button can access different applications. This parameter-based differentiation allows the terminal to maintain simple hardware (few keys) while providing access to many applications, thus preserving ease of operation despite increased versatility.
