Off-Screen Active Window Stack for Application Preloading

The patent applies preliminary action by creating an active window stack with boundary coordinates outside the display screen area before the application needs to be launched. This allows the application interface to be pre-rendered and prepared in advance in an off-screen buffer, so that when the user selects to launch the application, the interface is already ready and can be quickly displayed without the several seconds to ten seconds delay experienced in conventional loading methods.

The patent applies dimensionality change by utilizing a virtual coordinate space that extends beyond the physical display screen boundaries. The active window stack is created with boundary coordinates in this extended dimensional space, allowing the application interface to be rendered in an off-screen buffer that exists in the same memory address space but outside the visible display area. This approach uses existing memory resources more efficiently rather than allocating separate dedicated memory for preloading.

The patent applies universality by designing the active window stack structure to serve multiple functions: it can hold both on-screen and off-screen application interfaces, manage both visible and preloaded applications, and coordinate both display and preload operations through a unified coordinate system. The boundary coordinates mechanism is designed to be universal, working with any application interface size and position, whether within or outside the display screen area, thereby managing complexity through a single versatile system rather than separate mechanisms for different scenarios.
