POI Selection via Closed Curve Touch Gesture on Portable Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing Point Of Interest (POI) information in portable terminals with Mixed Reality (MR) technology face challenges when there are many icons on the screen, making it difficult to select individual icons, and require manual camera movement to focus on topographical features outside the predetermined area.
Innovation Solution
A method and apparatus that display POI information within a closed curve drawn by the user's touch on a portable terminal, allowing for intuitive selection and transmission of this information to other mobile stations through messages, including link function menus like 'Auto Calling', 'Web Link', and 'Navigation'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple POI icons are displayed on the screen, then more POI information can be provided, but it becomes difficult to individually select the icons that the user intends to view
Solution Approach 1:
The patent divides the screen into multiple selectable regions or zones, each potentially containing POI icons. Users can select entire regions rather than individual icons, making selection easier when multiple POI icons are present. This segmentation approach allows the system to handle multiple POI icons (improving quantity) while simplifying user interaction through region-based selection (improving ease of operation).
Solution Approach 2:
The patent implements different interaction modes or selection methods for different areas of the screen. Certain regions may support different selection mechanisms (e.g., tap, long-press, drag) depending on the density and type of POI icons in that local area. This allows the system to accommodate varying numbers of POI icons across different screen regions while maintaining ease of operation in each specific context.
2Device complexity
If a predetermined focus area is used to display POI information, then the display structure is simplified, but the user has to manually move the camera to include topographical features outside the focus area
Solution Approach 1:
The patent makes the focus area dynamic rather than fixed. The focus area can automatically adjust its position and size based on user interactions (such as drag gestures), detected POI locations, or camera movement. This dynamic focus area maintains a simplified display structure (one unified area) while eliminating the need for manual camera adjustment, as the system automatically adapts the focus area to include desired topographical features.
Solution Approach 2:
The system performs automatic camera adjustment or focus area repositioning based on detected POI information and user preferences. Rather than requiring the user to manually move the camera, the system self-adjusts the focus area to encompass relevant POIs and topographical features, thereby simplifying the display structure while improving ease of operation through automation.
3Ease of operation
If POI information is displayed only within a predetermined focus area, then the information display is controlled, but POI information outside the focus area cannot be accessed
Solution Approach 1:
The patent extends POI information access beyond the two-dimensional focus area by implementing a multi-layered or multi-dimensional information architecture. Users can access POI information through gestures (e.g., dragging across the screen) that traverse from the focus area to other regions, or through overlay interfaces that display additional POI data in a different dimensional space (such as a side panel or popup). This allows controlled information display within the focus area while simultaneously providing access to POI information outside that area.

AI summary
A method and apparatus for providing Point Of Interest (POI) information in a portable terminal are provided. The method includes displaying an image mapped with at least one POI on a screen, sensing if the screen is touched in a closed curve shape, and displaying information on the POI mapped to an area within a closed curve of the displayed image.
