Solution Overview
Problem
Electronic devices face difficulties in intuitively verifying hierarchical structures and movement ranges between classes, requiring multiple operations and struggling with screen division, especially when classification states change.
Innovation Solution
An electronic device with an input interface, memory, and processor that provides a preview of the function execution screen and changes classes or screen layouts based on user input, allowing users to verify and change classification states and screen divisions intuitively by outputting a preview of the intended changes during input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device changes classification states of items according to class changes, then the items can be organized into hierarchical structures, but it becomes difficult to intuitively verify the hierarchical structure and movement range between classes
Solution Approach 1:
The patent applies preliminary action by displaying a preview of the change screen before the classification state change is finalized. When a user performs a gesture (e.g., pinch gesture), the system first shows what the screen will look like after the change, allowing the user to verify the hierarchical structure and movement range intuitively. Only after user confirmation (e.g., lifting fingers) does the actual classification change occur. This resolves the contradiction by enabling intuitive verification before the change is committed.
2Adaptability or versatility
If the electronic device performs multiple operations for movement range corresponding to multiple classes, then comprehensive class navigation is achieved, but the operation complexity increases
Solution Approach 1:
The patent merges multiple operations into a single gesture-based operation. Instead of requiring separate operations for each class transition, the system uses a single pinch gesture that can navigate through multiple classes while displaying previews. The gesture's magnitude and direction determine the movement range, allowing comprehensive class navigation in one action rather than multiple discrete operations, thus reducing operation complexity while maintaining versatility.
Solution Approach 2:
The patent introduces a new dimension of interaction by using gesture magnitude (pinch distance) to control movement range between classes. This adds a spatial dimension to class navigation, where the physical distance of the gesture correlates with the number of classes to traverse. This dimensional approach simplifies operation by allowing users to navigate multiple classes intuitively through gesture strength rather than multiple discrete steps.
3Adaptability or versatility
If the electronic device divides the screen to display multiple applications, then multitasking capability is improved, but the operations to divide the screen become troublesome
Solution Approach 1:
The patent applies preliminary action by showing a preview of the divided screen layout before the actual screen division occurs. When a user performs a gesture indicating screen division intent, the system first displays how the screen will be divided and which applications will be shown in each region. This allows users to verify the layout intuitively before committing to the division, making the operation less troublesome while maintaining multitasking capability.

AI summary
An electronic device is provided. The electronic device includes an input interface configured to receive a user input, a memory configured to store an application using an item, a display, and a processor. The processor is configured to obtain the user input through the input interface while an execution screen of the application is output, determine a change screen based on a variation of the user input, wherein the change screen is configured to be outputted when the user input is released, and while the user input is maintained, output a preview which includes at least part of the change screen to the display.
