Mobile Terminal Content Rotation via Acceleration Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals with multiple display regions face challenges in maintaining user convenience when displaying multiple contents, as users tend to view them in specific directions, and the display order and size need to be adjusted based on the device's orientation to maximize usability.
Innovation Solution
A method for controlling the operation of a mobile terminal using an acceleration sensor to rotate and scale content displayed on multiple display regions based on the device's orientation, ensuring that content is displayed vertically or horizontally while maintaining a uniform display direction, and adjusting scroll bars and content positions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple contents are displayed in two or more display regions, then the information display capability is improved, but the user convenience deteriorates because users tend to view display regions in fixed directions and the display order becomes inconsistent
Solution Approach 1:
The patent applies dynamics by making the display configuration adaptive rather than static. The controller dynamically adjusts the display order, direction, and size of multiple contents based on real-time detection of mobile terminal orientation using an acceleration sensor. This allows the display layout to change automatically between horizontal and vertical arrangements, maintaining user convenience while displaying multiple contents simultaneously.
Solution Approach 2:
The patent changes display parameters (order, direction, size) based on terminal orientation parameters. When the terminal is rotated, the controller detects the orientation change and modifies display parameters accordingly - such as switching from horizontal to vertical display order, adjusting content sizes, and rotating content orientation - to maintain consistent viewing experience across different terminal positions.
2Adaptability or versatility
If the mobile terminal is rotated to change display orientation, then the adaptability to different viewing positions is improved, but the complexity of controlling display direction and content order increases
Solution Approach 1:
The system performs self-service by automatically detecting terminal orientation through the acceleration sensor and autonomously adjusting display configurations without requiring manual user intervention. The controller continuously monitors orientation data and automatically reconfigures the display layout, content order, and sizes based on detected terminal position, eliminating the need for complex manual control mechanisms.
Solution Approach 2:
The patent implements feedback by using the acceleration sensor to continuously monitor terminal orientation and feeding this information back to the controller. The controller processes this feedback and automatically adjusts display parameters accordingly, creating a closed-loop system that adapts to terminal orientation changes while simplifying user interaction.
3Ease of operation
If content size and position are adjusted based on terminal rotation, then the viewing optimization is improved, but the complexity of display control increases
Solution Approach 1:
The patent makes content display dynamic by automatically adjusting content size, position, and orientation based on real-time terminal rotation detection. The controller dynamically recalculates and repositions multiple contents within display regions, scaling them appropriately and maintaining optimal viewing configurations without requiring complex manual adjustment mechanisms.

AI summary
A mobile terminal is provided including a display module, an acceleration sensor, and a controller. The display module is for displaying first content and second content. The acceleration sensor is for providing measurement data on a direction of gravitational acceleration. The controller is configured to display the first content and the second content in line vertically and to rotate the first content and the second content when the measurement data indicate that the mobile terminal has been rotated to a first position while uniformly maintaining a display direction of the display module. The controller is further configured to display the first content and the second content in line horizontally and to rotate the first content and the second content when the measurement data indicate that the mobile terminal has been rotated to a second position while uniformly maintaining the display direction of the display module.
