Display Device Magnification and PIP Information Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when trying to view detailed information related to a specific area on a display device, as they need to perform a separate search function to access this information, which is not seamlessly integrated with the area enlargement feature.
Innovation Solution
A display device and control method that allows users to select a specific area, enlarge it, and display detailed information on a main screen, with the option to view more detailed information on a PIP (Picture-in-Picture) screen, and search for objects within the detailed information, all controlled through a remote controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user enlarges a specific area of map information on the display device, then the specific area is displayed in greater detail, but the user cannot simultaneously view detailed information related to that specific area without performing a separate search function
Solution Approach 1:
The patent combines the enlarged specific area display and the detailed information display into a single unified interface. The detailed information about the specific area is automatically retrieved and displayed alongside the enlarged area, eliminating the need for separate search operations. This merging of functions allows users to view both the visual details of the specific area and its associated information simultaneously.
Solution Approach 2:
The system performs preliminary actions by automatically retrieving detailed information about the specific area immediately when the user enlarges that area. The search and information retrieval functions are executed in advance, before the user needs to view the information, so that the data is ready and displayed without requiring additional user actions.
2Ease of operation
If the display device shows both the enlarged specific area and detailed information on the same screen, then user convenience is improved, but the screen space and display layout become more complex
Solution Approach 1:
The display screen is segmented into distinct functional regions: one region displays the enlarged specific area of the map, while another region displays the detailed information related to that area. This segmentation allows both types of content to be presented simultaneously without overwhelming the user or creating a cluttered interface, as each element has its designated space.
Solution Approach 2:
The patent utilizes the vertical dimension of the display screen to arrange content. The enlarged map area and the detailed information are positioned in different vertical zones, allowing both to be visible simultaneously. This dimensional arrangement solves the space constraint by effectively using the screen's height to separate and display multiple types of information without horizontal crowding.
3Loss of information
If the display device provides multiple levels of detailed information, then information completeness is improved, but the information management and retrieval process becomes more complex
Solution Approach 1:
The system performs preliminary information retrieval by automatically obtaining detailed information about the specific area when the user enlarges it. The multi-level information is fetched and organized in advance, so that when the user views the enlarged area, the corresponding detailed information is already prepared and ready for display, reducing the complexity of real-time information management.
Solution Approach 2:
The system implements a feedback mechanism where the display of detailed information is directly linked to the user's action of enlarging a specific area. When the user enlarges an area, the system automatically retrieves and displays relevant information; when the user navigates to a different area, the information updates accordingly. This feedback loop simplifies information management by making the system responsive to user actions rather than requiring manual information retrieval.
