AR HUD Vehicle Trajectory Guidance for Intuitive Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving information guidance systems fail to provide intuitive and realistic navigation using augmented reality (AR) on head-up displays (HUDs), lacking dynamic adjustments based on vehicle conditions such as speed, road width, and curvature.
Innovation Solution
A driving information guidance method and system that generates AR objects representing virtual trajectories on HUDs, dynamically controlling spacing, color, and shape of lines based on vehicle speed, road conditions, and ADAS data, to provide more intuitive and realistic driving information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional navigation systems are used on HUD, then basic directional information is provided, but the navigation is not intuitive or realistic enough
Solution Approach 1:
The patent creates a virtual copy of the real road environment by generating a three-dimensional virtual trajectory that mirrors the actual driving path. This virtual copy is displayed on the HUD to provide intuitive and realistic navigation guidance, allowing drivers to perceive their position and direction more naturally without abstract map representations.
Solution Approach 2:
The patent transitions from two-dimensional map-based navigation to three-dimensional virtual trajectory representation. By adding the depth dimension and creating a spatially accurate virtual path that matches the real-world driving environment, the system enhances both intuitiveness and realism of navigation information.
2Device complexity
If fixed spacing lines are used for trajectory, then simple display is achieved, but dynamic driving conditions like speed changes are not reflected
Solution Approach 1:
The patent implements dynamic line spacing that automatically adjusts based on vehicle speed and driving conditions. When the vehicle accelerates, the spacing between trajectory lines increases to reflect the changed speed state. This dynamic adaptation maintains visual accuracy without requiring complex additional displays.
Solution Approach 2:
The system continuously monitors vehicle speed and position data, then feeds this information back to adjust the trajectory line spacing in real-time. This feedback mechanism ensures the visual representation remains synchronized with actual driving conditions, providing accurate speed feedback through the spacing pattern.
3Loss of information
If multiple trajectory lines are displayed, then comprehensive navigation information is provided, but visual clarity may be compromised
Solution Approach 1:
The patent applies different visual properties to different parts of the trajectory lines. The spacing between lines varies locally based on vehicle speed, with wider spacing indicating higher speeds and narrower spacing indicating lower speeds. This local variation in line quality provides comprehensive speed and position information while maintaining overall visual clarity through controlled differentiation.

AI summary
A travel information notification method includes generating an augmented reality object composed of a plurality of lines that indicate a virtual trajectory corresponding to at least a portion of a predicted travel path of a vehicle; providing the generated augmented reality object on a head-up display of the vehicle so that the plurality of lines display the virtual trajectory in association with the road on which the vehicle is traveling; and providing travel information about the vehicle by controlling at least one among the spacing, colors, or shapes of the plurality of lines, displayed as the augmented reality object on the head-up display, according to travel conditions of the vehicle.
