Dynamic Navigation Display Adaptation for Travel Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional map display apparatuses lack convenience as the information/menu window is not adapted to vehicle travel conditions, making it difficult for users to view the map screen and menu simultaneously.
Innovation Solution
A navigation apparatus that includes an own-vehicle position identification unit, input unit, map database, route search unit, display controller, display map generator, and display menu generator, which adjusts the view mode of the map screen and menu window based on travel conditions such as speed and proximity to intersections, optimizing the display for easier user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the menu window is displayed on the map screen to provide information to the user, then the information availability is improved, but the map screen visibility deteriorates because the menu window may hide the guided route
Solution Approach 1:
The patent applies dynamics by making the menu window movable and resizable rather than fixed. The menu window can be dynamically repositioned to non-overlapping areas and its size adjusted based on user needs, allowing both information display and map visibility to be optimized simultaneously
Solution Approach 2:
The patent segments the display area by identifying non-overlapping regions between the menu window and guided route. The system divides the screen into functional zones and positions the menu window in areas that do not interfere with the guided route display, ensuring both elements remain visible
2Reliability
If the menu window is positioned to avoid hiding the guided route, then the map screen visibility is improved, but the information display capability deteriorates due to limited available space
Solution Approach 1:
The patent implements dynamic resizing of the menu window based on the available non-overlapping area. When space is limited, the menu window automatically adjusts its size to fit within the available region while maintaining all necessary information display functions
Solution Approach 2:
The system changes the parameter of menu window size dynamically based on the calculated available display area. By adjusting the window dimensions according to spatial constraints, the system maximizes information display within the limited non-overlapping region
3Device complexity
If a fixed menu window layout is used to simplify the display system, then the device complexity is reduced, but the user convenience deteriorates because the display cannot adapt to different viewing conditions
Solution Approach 1:
The patent implements self-service by enabling users to freely move and resize the menu window according to their personal preferences and viewing conditions. The system provides automatic positioning in non-overlapping areas and allows user-driven adjustments without requiring complex configuration settings

AI summary
A navigation apparatus is provided that is highly convenient for a user to view a map screen and a menu window. A display controller 15 determines a view mode of each of a map screen and a menu window, based on information about a travel condition of a moving object from a route search unit 12 and an own-vehicle location identification unit, when the menu window is displayed according to information entered from an input unit 10. A display map generator 16 generates a map screen according to information about the view mode from the display controller 15. A display menu generator 17 generates a menu window according to information about the view mode from the display controller 15. A display unit 21 displays the map screen from the display map generator 16 and the menu window from the menu generator 17.
