Map Moving Apparatus Shape Recognition Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems require users to perform cumbersome and distracting operations to move the map screen display region, making it difficult to obtain information about points of interest or road conditions while driving, as they lack an efficient method to automatically scroll the map along a selected route or area.
Innovation Solution
A map moving apparatus that recognizes user-input shapes and moves the map screen display region along identified polygons, providing guidance information and allowing for automatic movement based on polygon type and user input speed and direction, thereby simplifying the process of accessing information around selected areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the map screen display region is moved manually by user operation, then the user can view different areas on the map, but the operation becomes cumbersome and distracting for the driver
Solution Approach 1:
The map display system automatically moves and scrolls along the guiding route without requiring continuous manual input from the driver. The system uses the pre-set route data to autonomously navigate the map display, allowing the driver to simply observe the map movement and receive guidance information without operational burden or distraction
Solution Approach 2:
The guiding route is predetermined and stored in the system before the map display movement begins. By having the route pre-calculated and saved, the system can automatically follow this pre-established path for map navigation, eliminating the need for real-time manual route planning or continuous user input during driving
2Loss of information
If the map screen display region is moved along a route, then the display follows the guiding path, but information about points not near the route cannot be provided
Solution Approach 1:
The system provides different types of information at different locations relative to the route. Facilities and points of interest that are near the guiding route are displayed with detailed information, while areas farther from the route are shown with appropriate contextual information. This localized information delivery ensures completeness for route-relevant information while maintaining adaptability for broader geographic context
Solution Approach 2:
The map display system dynamically adjusts its behavior based on the vehicle's position and the type of polygon being traversed. When moving along linear polygons (roads), the system provides route-specific information. When moving along ring polygons (facilities, parks, bodies of water), the system provides information about the enclosed area and surrounding facilities, thus adapting the information coverage to the current display context
3Loss of information
If the user continuously operates the navigation system to move the map, then the map can be positioned to show desired areas, but the driver cannot focus on the road and safety is compromised
Solution Approach 1:
The navigation system autonomously handles map display movement along the guiding route without requiring continuous driver intervention. The system automatically scrolls the map, positions the display region, and provides guidance information, allowing the driver to maintain focus on the road while the system independently manages information presentation
Solution Approach 2:
The system provides automatic feedback by displaying guidance information about facilities, road conditions, and points of interest along the route. This feedback mechanism delivers necessary geographic information to the driver without requiring active manipulation of the system, thus maintaining both information accessibility and driving safety

AI summary
A map moving apparatus capable of performing desired map movement by a simple input operation without requiring a continuous operation by a user in moving a map screen display region is disclosed. An operated direction, an operated position, an operated speed and the like are detected from an input operation that a user performs on the map screen display region, and a map screen display region input shape recognizing section recognizes an input shape. A polygon shape identifying section extracts data having substantially the same shape as the recognized input shape from polygon data in map display data by using a matching method. When data having substantially the same shape exists, a type of the polygon is identified. In a movement mode selecting section, the movement of a screen map reverses direction when it reaches an end portion in the case where the polygon type is a linear shape, and the movement circulates to continue movement of the map screen where the type is a ring shape with no end portion. In the case where guidance information is detected during the movement of the map, guidance is provided on a screen or by voice.
