Dynamic Display Window Resizing with Guideline Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch-screen devices waste resources when changing display window sizes, and users face difficulties in accurately selecting and resizing small display windows.
Innovation Solution
A method and device that utilize user inputs to move guidelines for resizing display windows, allowing users to select and adjust the size of display windows with guide points and borders, while maintaining content resolution and within predetermined ranges, using a minimal number of resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the size of the display window is changed, then the display area is increased, but resources of the device are wasted
Solution Approach 1:
The display window size is made dynamic rather than fixed, allowing it to be adjusted according to user needs. The system dynamically changes the window size from an initial state to a modified state, optimizing the balance between display area and resource consumption based on actual usage requirements.
Solution Approach 2:
The patent changes the size parameter of the display window to resolve the contradiction. By adjusting the window size parameter, the system can increase display area when needed while avoiding unnecessary resource consumption when a smaller area suffices, thus optimizing the trade-off between these two parameters.
2Loss of energy
If the size of the display window is small, then resource usage is reduced, but it is difficult for a user to accurately select a portion of the display window
Solution Approach 1:
A selection indicator is introduced as an intermediary element to assist user selection. This indicator visually highlights the selected portion of the display window, making it easier for users to accurately select areas even when the window or selection area is small, thus resolving the contradiction between resource efficiency and selection precision.
Solution Approach 2:
The patent uses visual changes (such as color or brightness changes of the selection indicator) to enhance the visibility and detectability of the selected area. This helps users accurately identify and select portions of the display window regardless of the window size, improving measurement precision without requiring larger display areas.
3Adaptability or versatility
If the size of the display window is changed, then user interface flexibility is improved, but contents must be re-displayed which consumes additional resources
Solution Approach 1:
The system performs preliminary actions by maintaining content data in memory and using the selection indicator to pre-identify the area of interest. When the user confirms the selection, the system can efficiently process and display only the necessary content at the new window size, avoiding complete re-display of all contents and thus reducing resource consumption while maintaining interface flexibility.

AI summary
A device for and method of changing a size of a display window on a screen are provided. The method includes receiving a user input for changing the size of the display window, moving a guideline and displaying the moving guideline according to the user input, the guideline indicating the size of the display window, determining a changed size of the display window after the user input is terminated, and displaying the display window with the determined changed size, wherein contents are displayed in the displayed display window.
