Motion Recognition Screen Mode Control via Axis Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals require manual switching of display orientation, which can lead to unintended changes, necessitating a method to differentiate between user-intended and unintended horizontal/vertical switching.
Innovation Solution
A three-axis sensor system that measures terminal movement and compares changes in axis values to determine whether to switch the screen mode, maintaining the current orientation if one axis changes more than the others and switching only when intentional changes are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching method is used for display orientation, then user can control screen mode, but unintended switching occurs and user experience deteriorates
Solution Approach 1:
The patent introduces an acceleration sensor as an intermediary device that detects terminal movement and provides objective data to distinguish intentional from unintentional switching. The sensor acts as a mediator between user action and system response, enabling the controller to make intelligent decisions about whether to switch display orientation based on detected acceleration patterns.
Solution Approach 2:
The system implements feedback by continuously monitoring acceleration sensor data and comparing it against threshold values to determine whether a switching action should be triggered. The controller receives real-time feedback from the sensor about terminal movement, processes this information, and adjusts the display orientation accordingly, creating a closed-loop control system that prevents unintended switching.
2Reliability
If automatic motion recognition is implemented, then unintended switching is prevented, but device complexity increases due to additional sensor and processing requirements
Solution Approach 1:
The acceleration sensor and controller work together in a self-service manner where the sensor automatically detects movement patterns and the controller autonomously decides whether to switch display orientation based on predefined criteria. This self-service mechanism eliminates the need for manual user input while maintaining high switching accuracy, and the complexity is managed through automated decision-making algorithms.
Solution Approach 2:
The system utilizes parameter changes in acceleration values detected by the sensor to determine switching intent. By monitoring changes in acceleration magnitude and direction against threshold parameters, the system can distinguish between intentional switching actions and accidental movements, achieving high reliability through parameter-based decision-making without requiring complex processing.

Data Source
AI summary
An apparatus and a method for changing a screen mode depending on a posture and movement of a terminal are provided. A motion sensor measures a value of a three-axis sensor that changes depending on the posture or movement of the terminal, and transfers the measured value to the controller. A storage stores a plurality of screen modes corresponding to the posture or movement of the terminal. A controller determines the posture or movement of the terminal using the value of the three-axis sensor transferred from the motion sensor, and maintains the current screen mode a change in one of three axes is greater than the other two axes which indicates a user did not intended to switch the screen mode.
