Dynamic Layer Orientation for Seamless Display Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an electronic device rotates, preview images are often cut off due to system windows and other overlays being fixed in position, causing inconvenience to users as they do not adapt to the device's orientation.
Innovation Solution
An electronic device and method that senses rotations and adjusts the direction of layers within applications, ensuring system windows and overlays match the device's orientation, thereby maintaining a seamless view without image cutoffs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If system windows and overlays are fixed in position, then application stability is maintained, but preview images are cut off during device rotation
Solution Approach 1:
The patent applies the Dynamics principle by making system windows and overlays dynamically adjustable during device rotation. Instead of fixing layers in static positions, the system detects rotation events and automatically adjusts the position and orientation of each layer to match the new device orientation, allowing both stability and rotation adaptability
2Adaptability or versatility
If each layer rotates independently, then layer-specific orientation is maintained, but coordinate misalignment occurs between layers
Solution Approach 1:
The patent implements the Feedback principle by continuously monitoring the rotation state of the device and adjusting layer coordinates based on this feedback. When rotation is detected, the system calculates the new orientation angle and uses it to update the coordinate system for all layers, ensuring they remain aligned with each other while adapting to the new orientation
Solution Approach 2:
The patent applies the Universality principle by creating a unified coordinate transformation system that handles all layers simultaneously. Instead of treating each layer independently, the system uses a common rotation angle and transformation matrix applied to all layers, ensuring consistent coordinate alignment across the entire interface while allowing each layer to adapt to rotation
3Reliability
If camera application is configured for fixed position, then preview image display is stable, but system windows do not adapt to rotation causing viewing inconvenience
Solution Approach 1:
The patent applies the Segmentation principle by dividing the interface into separate rotatable layers - the camera preview layer and the system window layer. Each layer can be independently positioned and oriented, allowing the preview image to maintain its stable display while system windows separately adapt to rotation, resolving the conflict between stability and viewing convenience

AI summary
An electronic device and a method for controlling a display are provided. The method includes sensing, via the electronic device, a rotation of the electronic device, identifying, by the electronic device, at least one layer having direction information that is different from a direction of the sensed rotation among a plurality of layers included in an application, changing, via the electronic device, a direction of the identified at least one layer to a direction corresponding to the sensed rotation, and displaying, via the electronic device, the application including the changed at least one layer.
