AR Navigation Overlay Using a Virtual Leading Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems in vehicles often struggle with providing clear instructions, especially in complex or low-visibility conditions, leading to increased chances of missed exits or turns.
Innovation Solution
A system that utilizes augmented reality to display a virtual leading vehicle on the vehicle's interface, determining the type based on biometric indicators, user preferences, and sensor data to enhance navigation, including potential collisions, glare, weather, and vehicle capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional navigation systems use verbal and written instructions with map arrows, then the system complexity remains low, but the ease of operation deteriorates in complex intersections or low-visibility conditions
Solution Approach 1:
The patent transitions navigation instructions from a 2D map representation to a 3D augmented reality overlay that projects virtual navigation elements (arrows, signs, vehicle icons) directly onto the driver's view of the real road environment. This dimensional change allows drivers to see navigation guidance in the context of the actual road layout, significantly improving ease of operation at complex intersections and in low-visibility conditions without requiring complex additional hardware beyond the existing camera and display systems
Solution Approach 2:
The patent introduces an augmented reality display as an intermediary between the navigation system and the driver. This intermediary processes and overlays multiple sources of information (map data, camera feeds, sensor data) to create an intuitive visual guide that shows the driver exactly where to steer and what to expect ahead, reducing the cognitive load of interpreting separate verbal and map-based instructions
2Reliability
If conventional navigation systems overlay navigation signs on highway representations, then device complexity remains low, but reliability deteriorates leading to missed exits or turns
Solution Approach 1:
The patent displays virtual navigation elements and road features ahead of the driver's current position, allowing the driver to anticipate upcoming turns, exits, or intersections before reaching them. The system shows the intended path and upcoming maneuvers in advance, giving the driver time to prepare and execute turns accurately, thereby improving reliability without requiring complex real-time intervention mechanisms
Solution Approach 2:
The patent creates a virtual copy of the road environment and navigation guidance that is overlaid onto the driver's view of the actual road. This virtual representation includes scaled and positioned icons for exits, turns, and navigation directions that mirror the real-world geometry, providing an intuitive and accurate guide that reduces missed turns while maintaining system simplicity
3Ease of operation
If the system displays detailed navigational instructions via augmented reality interface, then ease of operation improves, but use of energy increases due to multiple sensors and processing requirements
Solution Approach 1:
The patent makes the navigation system multi-functional by using the same camera, processor, and display infrastructure for both standard navigation guidance and advanced augmented reality overlays. The system can operate in multiple modes (basic map view, augmented reality view, different levels of detail) depending on driving conditions and user preferences, allowing it to provide clear navigation instructions while managing energy consumption by activating full AR features only when necessary

AI summary
Extended reality augmentation of situational navigation (e.g., using a computerized tool) is enabled. For example, a system can comprise: a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising: based on a route of a vehicle, determining a navigational instruction to be displayed via an augmented reality interface of the vehicle, and displaying the navigational instruction via the augmented reality interface, wherein displaying the navigational instruction comprises displaying a virtual leading vehicle to be followed by the vehicle.
