Map Display Scale Switching for In-Vehicle Navigation Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle navigation systems face issues with visibility deterioration when switching from full-screen to window display modes, as the map area and scale settings are often interlocked, leading to incomplete map visibility.
Innovation Solution
An information processing device that allows independent scale settings for different display arrangements, such as full-screen and window modes, ensuring continuous map visibility by maintaining scale consistency within each mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the map scale is interlocked with display arrangement, then the system is simpler to control, but the map visibility deteriorates when switching between full-screen and window modes
Solution Approach 1:
The patent segments the scale setting into display arrangement-specific parameters, maintaining independent scale control for full-screen and window modes. This allows each display arrangement to have its own optimized scale setting, preventing visibility loss when switching modes.
Solution Approach 2:
The patent implements parameter changes by storing separate scale values for different display arrangements and dynamically selecting the appropriate scale based on the current display mode. This ensures continuous map visibility while maintaining system simplicity.
2Device complexity
If the map scale is interlocked with display arrangement, then the control mechanism is simpler, but the desired scale setting cannot be maintained during mode transitions
Solution Approach 1:
The control mechanism is segmented into display arrangement-specific scale management, where each mode (full-screen, window) has its own scale settings stored and applied independently. This maintains stability of scale settings during mode transitions.
Solution Approach 2:
The system performs preliminary action by pre-configuring and storing appropriate scale values for each display arrangement before mode switching occurs. This ensures that when a user switches modes, the desired scale setting is already prepared and applied immediately, maintaining consistency.
3Loss of information
If independent scale settings are provided for each display arrangement, then map visibility is maintained during mode switching, but the device complexity increases
Solution Approach 1:
The patent implements universality by using a single control unit that manages scale settings for both display arrangements. The control unit selectively applies the appropriate scale based on the current display mode, providing multi-functional capability without requiring separate independent control systems for each mode.

AI summary
An information processing device capable of displaying a map by any one of a first display arrangement and a second display arrangement in which a display area on a screen of a display device is different. A control unit for executing switching between the first display arrangement and the second display arrangement based on a first operation performed by a user, and changing a scale of the map being displayed based on a second operation performed by the user, wherein the control unit changes a scale in a case where the map is displayed in the first display arrangement when the second operation is performed while the map is being displayed in the first display arrangement, and does not change a scale in a case where the map is displayed in the second display arrangement.
