Navigation Display Switching to 3D Map for Indoor Destination Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems struggle to provide clear and comprehensible route guidance, especially when the destination is not directly accessible via the road network and requires navigation within a building or specific location, such as a meeting room, without relying on map displays.
Innovation Solution
The method involves automatically switching to a 3-dimensional map display for the last leg of the journey, providing detailed route guidance information that includes building features like floors, elevators, and rooms, and integrates data from an electronic calendar to align navigation with appointment times, allowing for enhanced user guidance beyond conventional route planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If route guidance information is output in a map-free representation, then the display is simple and easy to understand, but the user cannot obtain an overview of the surroundings of the destination
Solution Approach 1:
The patent divides the route guidance display into two distinct segments: a map-free representation for general route instructions and a 3-dimensional map display specifically for showing the destination surroundings. This segmentation allows each display mode to optimize for its specific purpose without compromise
Solution Approach 2:
The patent transitions from a 2-dimensional map-free display to a 3-dimensional map display when approaching the destination. This dimensional change provides spatial context and overview of the destination surroundings that cannot be achieved in 2D, while maintaining the simplicity of map-free display for the majority of the route
2Loss of information
If comprehensive route planning information is provided, then the user receives detailed guidance, but the information becomes overwhelming and difficult to comprehend
Solution Approach 1:
The patent applies different display qualities to different parts of the route guidance: map-free representation with simplified information for the majority of the route, and 3-dimensional map display with detailed spatial information only in the vicinity of the destination. This local differentiation prevents information overload while maintaining completeness
Solution Approach 2:
The patent provides partial map information (3-dimensional view) only when necessary near the destination, rather than displaying complete map information throughout the entire journey. This partial action approach delivers sufficient information for destination orientation without the overwhelming detail that would accompany full map display

AI summary
The invention relates to a method for navigating to a destination, in which, depending on the current position and the destination, navigation instructions are displayed on a screen (1) in a 2-dimensional map display or in a mapless display. The last navigation instructions before reaching the destination are automatically displayed in a 3-dimensional map display. The invention further relates to a device for navigating to a destination comprising a screen (1), a positioning device (2), and a controller (3), which is configured to display navigation instructions on the screen (1) in a 2-dimensional map display or in a mapless display, depending on the current position and the destination. The controller (3) is configured to automatically display the last navigation instructions before reaching the destination in a 3-dimensional map display.
