Geographic Application Screen Orientation Transition Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geographic applications fail to efficiently and intuitively manage the presentation of digital maps and geographic content across different physical orientations of a display device, such as portrait and landscape, leading to suboptimal use of screen real estate and user experience.
Innovation Solution
A method where processors generate and manage multiple presentation formats of geographic content based on the current and previous orientations of the display device, storing indications of previous presentations to restore formats efficiently when the device orientation changes, ensuring seamless transitions and intuitive user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the geographic application generates different presentation formats for different device orientations, then the adaptability and user experience are improved, but the device complexity and processing overhead increase
Solution Approach 1:
The system pre-generates and stores multiple presentation formats for different device orientations before they are needed. When an orientation change occurs, the system simply retrieves the pre-prepared presentation format corresponding to the new orientation, avoiding complex real-time generation and reducing processing overhead during actual orientation transitions.
Solution Approach 2:
The system creates and stores copy instances of geographic content presentations for different orientations. Instead of generating presentations from scratch during orientation changes, the system maintains pre-generated copies of presentations optimized for each orientation, enabling instant switching without complex real-time processing.
2Ease of operation
If the application stores indication of previous presentation to restore upon orientation change, then the ease of operation is improved, but the memory usage increases
Solution Approach 1:
The system extracts and stores only the essential indication data needed to restore the previous presentation format, rather than storing complete presentation instances. This selective extraction minimizes memory usage while preserving the capability to restore presentations intuitively when device orientation changes.
3Productivity
If the system generates presentations in response to orientation changes, then the productivity of presentation updates is improved, but the loss of time during transitions increases
Solution Approach 1:
Presentation formats for different orientations are generated and prepared in advance, before orientation changes occur. This preliminary generation eliminates the need for time-consuming real-time processing during actual orientation transitions, reducing perceived transition time while maintaining efficient presentation updates.
Solution Approach 2:
Pre-generated copies of presentations for different orientations are stored and instantly retrieved upon orientation change. This copying approach eliminates the time delay associated with generating presentations during transitions, as the system simply switches to the pre-prepared copy corresponding to the new orientation.

AI summary
The display device of a portable device is configured to operate in at least a first physical orientation and a second physical orientation. Instructions, when executed on one or more processors, cause the one or more processors to detect a first transition from the first physical orientation of the display device to the second physical orientation of the display device, detect a second transition from the second physical orientation of the display device to the first physical orientation of the display device, and, in response to the second transition, select a presentation format for displaying geographic content via the display device in the first physical orientation, based at least in part on a prior presentation format according to which the geographic content was presented via the display device prior to the first transition.
