Portable Device Display with Resizable Mini Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen portable devices are inconvenient for single-handed manipulation due to their size, requiring users to use two hands to grip and operate, making it difficult to access the screen's edges.
Innovation Solution
A method and apparatus that enable single-handed operation by displaying a translucent reduced image on the screen, which can be adjusted in size and location, allowing users to perform functions through touch inputs, including size and movement adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen size is enlarged to support various functions, then the display area and functionality are improved, but the ease of single-handed manipulation deteriorates
Solution Approach 1:
The patent divides the screen into two functional zones: a large original image display area for comprehensive information presentation and a small reduced image area for interactive manipulation. This segmentation allows the screen to maintain large display area while providing a manageable interaction zone that can be easily accessed with one hand.
Solution Approach 2:
The patent creates a reduced image that is a scaled-down copy of the original image. This copy retains the same functional elements (icons, buttons, information) but in a smaller format that can be easily manipulated with one hand while the original large image remains visible in the background.
2Area of stationary object
If the screen size is enlarged to support various functions, then the display capability is improved, but the accessibility to screen edges deteriorates
Solution Approach 1:
The patent segments the interactive functionality into a separate reduced image zone that can be positioned optimally for hand access. This allows the main display area to extend to screen edges for comprehensive information display while the interaction zone remains accessible to single-handed operation.
Solution Approach 2:
The patent introduces a dimensional transformation by creating a scaled-down version of the interface. This reduced image exists in a different size dimension, allowing users to interact with the screen edges more easily while the original large image maintains its full display area.
3Ease of operation
If a reduced image is displayed to enable single-handed operation, then the ease of manipulation is improved, but the display area for original content deteriorates
Solution Approach 1:
The patent merges the original image and reduced image into a unified display layout where both coexist on the same screen. The original image occupies the majority of the display area for comprehensive content presentation, while the reduced image is overlaid or positioned to provide interactive functionality without significantly reducing the overall display area.
Solution Approach 2:
The display system serves multiple functions simultaneously: the original image provides comprehensive information display while the reduced image provides interactive manipulation capability. This multi-functionality allows the screen to maintain large display area while enabling single-handed operation through the overlaid reduced image.

AI summary
A method of displaying images on a screen of a portable device is provided. The method includes entering a mini mode and displaying a reduced image, which is the same as an original image with a smaller size than that of the original image, in the mini mode on the screen; detecting a touch input which is generated on the reduced image; and performing a function corresponding to the touch input.
