Adaptive Virtual Key Repositioning for Mobile Display Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user equipment designs, such as mobile phones, face inconvenience when switching between landscape and portrait modes, as system keys are often placed on the sides, making it difficult for users to access them, thereby affecting user operation and experience.
Innovation Solution
A display control method that detects changes in screen direction using sensors like G-sensors, thermal identifying devices, or face recognition, and moves system visual keys to the title bar, allowing users to operate them from the top, thereby improving accessibility and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If system keys are placed on the sides of the display screen, then the device layout is simplified and manufacturing is easier, but user accessibility to keys deteriorates in landscape mode
Solution Approach 1:
The patent applies dynamics by making the key position adaptive rather than fixed. The system dynamically adjusts the position of virtual keys based on the detected screen orientation (portrait or landscape mode), ensuring keys remain accessible regardless of device orientation. This resolves the contradiction by allowing a simplified side-placement layout in portrait mode while automatically repositioning keys for accessibility in landscape mode.
Solution Approach 2:
The patent changes the positional parameter of virtual keys based on screen orientation detection. When the screen rotates from portrait to landscape mode, the system changes the key position parameter from side placement to top or bottom placement, maintaining user accessibility across different orientations while preserving the simplified side-layout benefit in portrait mode.
2Device complexity
If system keys are placed in fixed positions below the display screen, then device structure is simplified, but user operation convenience deteriorates when screen direction changes
Solution Approach 1:
The patent implements dynamics by making the virtual key position adaptive to screen orientation. Instead of using fixed physical key positions, the system dynamically repositions virtual keys based on real-time detection of screen direction changes, ensuring operational convenience is maintained across different orientations while keeping the physical device structure simple.
Solution Approach 2:
The patent uses virtual key copies that can be repositioned on the screen interface. Rather than moving physical keys, the system creates and repositions visual representations (copies) of system keys in different locations (side, top, or bottom) based on screen orientation, maintaining simple device structure while improving operational convenience.
3Device complexity
If key icons are only switched to position next to the title bar, then implementation is simple, but user convenience is still insufficient in landscape mode
Solution Approach 1:
The patent extends the parameter change approach by not only changing key position but also adjusting the placement location options based on screen orientation. In landscape mode, the system changes the placement parameter to offer top or bottom positions in addition to side positions, providing better user convenience while maintaining relatively simple implementation through virtual key repositioning.

Function Achieved in This Case
This solution facilitates user operation by allowing direct access to system keys from the title bar, even in landscape mode, enhancing user experience and allowing more content to be displayed on the screen by releasing the previous key area.
