Map Grid Display for Time Information Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying information on maps, such as those used in display apparatuses, face challenges in efficiently selecting and displaying time information for specific geographical areas, particularly due to difficulties in distinguishing and navigating between multiple display target areas on a grid-based map image.
Innovation Solution
A method and apparatus that divide a map image into adjustable grids, allowing users to select specific areas by moving a pointer using input devices like remote controls or touch panels, with the option to display time information for single or multiple areas within a grid, and provide pop-up windows for detailed information when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a map image is divided into multiple display target areas for showing time information, then the information display capability is improved, but the difficulty of distinguishing and navigating between areas increases
Solution Approach 1:
The map image is divided into multiple display target areas (first, second, third areas) with distinct functions: first area shows map overview, second area displays selected area information, and third area presents time information. This segmentation allows simultaneous display of multiple information types without overwhelming the user, resolving the contradiction between comprehensive information display and ease of navigation.
Solution Approach 2:
A pointer is introduced as an intermediary element to facilitate navigation between display target areas. The pointer visually indicates the currently selected area and responds to user input device operations, making it easier for users to distinguish and navigate between multiple areas while maintaining the ability to display comprehensive time information.
2Area of stationary object
If multiple display target areas are shown on a map image, then the coverage of geographical areas is improved, but the complexity of selecting specific areas increases
Solution Approach 1:
The pointer serves as a mediator between the user and the multiple display target areas. It simplifies the selection process by providing a clear visual indicator that moves in response to simple user inputs from the input device, reducing the complexity of selecting specific areas while maintaining broad geographical coverage.
Solution Approach 2:
The system provides visual feedback through the pointer's position and the content displayed in different areas. When the user operates the input device to select an area, the pointer moves to indicate the selection, and the corresponding time information is displayed in the third area. This feedback mechanism simplifies the selection process by making the current state and available options immediately clear to the user.
3Loss of information
If detailed information is provided for each display target area, then the information completeness is improved, but the ease of operation decreases
Solution Approach 1:
Information is segmented and displayed in different functional areas: the first area shows the map overview, the second area displays selected area details, and the third area presents time information. This segmentation allows complete information to be provided without overwhelming the user in a single location, maintaining ease of operation through organized, distributed presentation.
Solution Approach 2:
The system displays time information for multiple display target areas simultaneously in the third area, providing more information than a single-area display would offer. This partial display of excessive information (showing multiple areas' time data) maintains ease of operation by presenting all relevant information in a structured, easily scannable format without requiring complex user interactions.
Data Source
AI summary
A method for displaying time information and a display apparatus are provided. According to the method, a map image divided by a plurality of grids may be displayed and one of the grids on the displayed map image may be selected. Further, information about display target areas may be displayed when there are more than two display target areas in the selected grid and one of the information-displayed display target areas is selected. Furthermore, time information of the selected display target area may be displayed.
