Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In prior art touch screen mobile terminals, the menu key is displayed at a fixed position, making it difficult for users to select, especially when holding the device differently, leading to a deteriorated user experience.
Innovation Solution
A method and device that dynamically determine the relative state of the left and right sides of the screen using gravity sensing, adjusting the menu key's display position based on the user's holding manner, such as displaying it on the higher side when the left side is higher than the right or vice versa, and calculating optimal display positions using a ratio of valid to invalid operation trajectories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the menu key is displayed at a fixed position, then the display layout is simple and stable, but the ease of operation deteriorates when the user holds the device in different orientations
Solution Approach 1:
The menu key display position is changed from fixed to dynamic, automatically adjusting based on the device's orientation detected by gravity sensing. The system determines whether the left or right side is higher and positions the menu key accordingly, making the interface adaptive to different holding manners while maintaining operational ease.
Solution Approach 2:
The display position parameter of the menu key is changed dynamically based on orientation parameters detected by the gravity sensor. The system monitors the relative height of left and right sides and adjusts the menu key position parameter in response, resolving the contradiction between fixed layout simplicity and adaptive operation ease.
2Ease of operation
If the menu key position is adjusted dynamically based on orientation, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The system uses the device's built-in gravity sensing capability to automatically determine orientation and adjust menu key position without requiring additional sensors or complex processing. The existing sensor serves multiple functions, and the adjustment logic follows simple rules based on detected orientation, minimizing added complexity while improving operation ease.
Solution Approach 2:
The patent replaces complex mechanical or manual adjustment mechanisms with a software-based solution that uses gravity sensing data to automatically position the menu key. This substitution of mechanical complexity with software logic achieves adaptive display positioning with minimal additional device complexity.
