Context-Aware Screen Rotation for Intended Display Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen rotation methods in portable electronic devices do not consider the usability context of the displayed content, leading to potential user discomfort when the screen direction deviates from the user's intended orientation.
Innovation Solution
An electronic device that determines the display direction based on the analysis of the user interface context and the device's posture, adjusting the screen rotation angle only when it exceeds a threshold value specific to the context, thereby aligning with the user's intended orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If screen rotation is determined solely on the basis of quantitative physical change (sensor data), then the device responds quickly to device orientation changes, but the display direction may not match the user's intended screen direction and context usability
Solution Approach 1:
The system introduces feedback by analyzing the context of displayed content (such as whether the content is primarily text or image-based) and using this information to adjust screen rotation behavior. The processor determines the feature of context in UI components and uses this feedback to decide whether to rotate the screen, ensuring the rotation aligns with both the device orientation and the user's intended viewing direction for that specific content type.
Solution Approach 2:
The system changes the rotation threshold parameter dynamically based on context features. For different types of content (text-heavy vs. image-heavy), different rotation angle thresholds are applied. This allows the same sensor data to produce different rotation outcomes depending on the content being displayed, resolving the contradiction between rapid response and user comfort.
2Measurement precision
If the screen rotation threshold is set to be sensitive to small angle changes, then the screen rotates frequently to match device orientation, but it may rotate in situations not intended by the user (e.g., during typing or reading)
Solution Approach 1:
The system dynamically changes the rotation threshold parameter based on the detected context feature. For text-heavy content, a higher threshold is used to prevent unnecessary rotations during reading or typing. For image-heavy content, a lower threshold allows more frequent rotations to match the device orientation. This context-aware parameter adjustment resolves the contradiction between precise angle detection and user comfort.
Solution Approach 2:
The rotation threshold is not a fixed value but a dynamic parameter that changes based on the content being displayed. The system adapts the threshold in real-time according to the feature of the context, making the rotation behavior flexible and context-appropriate rather than rigid and uniform.
3Ease of operation
If the screen rotation is prevented for text-heavy content to maintain vertical display, then reading comfort is improved, but the device cannot adapt to legitimate rotation scenarios (e.g., when user intentionally rotates the device)
Solution Approach 1:
The system uses parameter changes by setting different rotation thresholds for different content types. For text-heavy content, a higher threshold maintains vertical display for reading comfort. However, if the device rotation angle exceeds this higher threshold, rotation is still permitted, thus maintaining adaptability to legitimate user intentions while preserving comfort for normal reading scenarios.
Solution Approach 2:
The system performs preliminary analysis of the content feature before determining rotation behavior. By pre-classifying the content as text-heavy or image-heavy, the system can pre-set appropriate rotation thresholds that balance reading comfort with adaptability to user intent.

Function Achieved in This Case
Ensures the screen rotation aligns with the user's intended direction, enhancing usability by considering the context of the displayed content, thus providing a more intuitive and comfortable viewing experience.
Implementation Method 1
The electronic device may calculate an angle change of the electronic device using at least an inertial sensor so that the direction of the screen viewed by the user does not substantially deviate from the direction of the displayed screen

AI summary
An electronic device may include a sensor; a display; and a processor operatively connected to the sensor and the display, wherein the processor may be configured to determine the feature of a context included in a user interface (UI) component on the basis of an analysis result of the UI component, determine a display direction of the contents displayed on the display on the basis of the feature of the context and the posture of the electronic device, identify a rotation angle of the electronic device through a sensor in accordance with a change in the posture of the electronic device in a state that the contents are displayed on the display, and change the display direction of the contents on the basis of identifying that the rotation angle is equal to or greater than a first value. The first value may be configured differently in accordance with the feature of the context.
