Virtual Input Keyboard Linkage for Multi-Field Touch Display

The patent divides the single keyboard system into multiple virtual input keyboards, each dedicated to specific application software or input methods. This segmentation allows users to select the appropriate virtual keyboard for each application without switching physical keyboards, thereby improving ease of operation while maintaining the physical simplicity of a single device.

The patent creates a universal input system where a single physical keyboard can serve multiple functions by implementing multiple virtual input keyboards. Each virtual keyboard can be configured for different applications, languages, or input methods, allowing the same physical device to handle diverse input requirements without adding physical complexity.

The patent implements a dynamic keyboard switching mechanism that automatically or manually activates the appropriate virtual input keyboard based on the current application or user selection. This dynamic approach allows the system to adapt to different input needs without requiring users to manually configure complex settings each time, thereby improving convenience while managing system complexity through automated control.

The patent introduces a keyboard management module as an intermediary that handles the complexity of multiple virtual keyboards. This mediator manages the activation, switching, and coordination of different virtual input keyboards, shielding users from the underlying system complexity while providing convenient access to multiple input methods through a unified interface.

The patent pre-configures multiple virtual input keyboards for different applications and input methods before the user needs them. The system anticipates the user's input needs by having the appropriate virtual keyboards ready and accessible, eliminating the need for time-consuming switching operations. Users can directly select from pre-prepared virtual keyboards that match their current application context.

The patent creates virtual copies of physical keyboards in software form, allowing multiple keyboard instances to coexist simultaneously. Each virtual keyboard is a software representation that can be independently activated without physically switching devices. This copying approach makes the switching process more intuitive as users interact with familiar keyboard layouts in different virtual contexts rather than dealing with physical device changes.
