Navigation Device Perspective View for Complex Intersections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation devices struggle to display complex intersections in an intuitively discernible manner, overwhelming drivers and making it difficult to correlate screen instructions with actual road situations, especially during unfamiliar maneuvers.
Innovation Solution
A navigation device and method that generate a single, shared perspective view of consecutive intersections based on their relative spatial position, using photographic or rendered images, and superpose additional graphic elements like signs and landmarks to provide a realistic and continuous visualization of the route, allowing drivers to recognize complex intersections easily.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional navigation systems display complex intersections as consecutive individual maneuvers or abstract 2-D map representations, then the navigation instructions can be provided, but the driver cannot intuitively recognize the correlation between the display and the actual road situation, leading to driver distraction and safety issues
Solution Approach 1:
The patent creates a virtual copy of the real-world intersection environment by generating a perspective view that replicates the actual road layout, buildings, and spatial relationships. This virtual copy is displayed on the navigation screen to provide drivers with an intuitive understanding of the complex intersection ahead, allowing them to correlate the display with the actual road situation without experiencing driver distraction
Solution Approach 2:
The patent transitions from conventional 2-D map representations to a 3-D perspective view that simulates the driver's actual viewing perspective of the road ahead. This dimensional change allows drivers to intuitively understand the spatial relationships and maneuver requirements at complex intersections by presenting navigation information in a format that mirrors their real-world visual experience
2Measurement precision
If conventional navigation systems provide detailed navigation instructions for complex intersections, then the navigation accuracy is improved, but the driver's attention must be split between the screen and the actual road, reducing safety
Solution Approach 1:
By creating a virtual copy of the actual road environment ahead, the system provides accurate navigation instructions that mirror the real-world situation. This allows drivers to understand complex maneuvers intuitively without needing to closely examine detailed symbolic representations, thereby maintaining navigation accuracy while reducing visual attention demands on the screen
Solution Approach 2:
The perspective view dynamically adapts to the driver's position and approach to the intersection, updating the virtual representation to reflect the current spatial relationship between the vehicle and the upcoming maneuver. This dynamic presentation provides continuously accurate navigation information in a format that naturally captures driver attention without requiring sustained focus on the screen

AI summary
A system and method for determining and displaying a navigation route on a navigation device from one vehicle position to a travel destination. The navigation device can include processor with RAM, a mass storage device for holding a database with geographic data, as well as a display. Depending on whether a complex intersection is present on the navigation route, the complex intersection can be shown on the display in the form of a single perspective view. Embodiments of the invention can provide a high level of correlation between the actual situation on the road as seen by the user and the corresponding navigation maneuver displayed on the screen. The graphic output of navigation devices for complex intersections can also be improved regardless of whether the navigation device is a high-performance or very simple device.
