AR HUD Navigation Markings with Reference Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality head-up display systems for vehicles face challenges in accurately positioning navigation markings, leading to potential misinterpretation by drivers due to inaccuracies, which can result in incorrect turns.
Innovation Solution
The implementation of a method that generates and displays both navigation markers and reference markers, where the reference markers help clarify the navigation markings by providing additional context, such as static or dynamic objects in the environment, to improve accuracy and reduce ambiguity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contact-analog navigation markers are displayed in the driver's field of vision, then navigation information is presented directly at the real-world location, but positioning inaccuracies can lead to misinterpretation and incorrect turns
Solution Approach 1:
The patent introduces reference markers as intermediary elements that mediate between the navigation marker and the driver's interpretation. These reference markers provide additional spatial context and help the driver correctly interpret the navigation marker's intended location and meaning, even when positioning inaccuracies occur. The reference markers act as a bridge that compensates for the imprecision in the main navigation marker's positioning.
Solution Approach 2:
The patent employs different visual characteristics (such as color, brightness, or style variations) to differentiate between navigation markers and reference markers. This visual differentiation helps the driver quickly distinguish the primary navigation instruction from the auxiliary reference information, improving the ease of interpretation while maintaining the spatial context provided by multiple markers.
2Measurement precision
If multiple markers are displayed to improve accuracy, then navigation clarity is enhanced, but the display complexity increases
Solution Approach 1:
The patent segments the navigation information display into two distinct functional components: primary navigation markers that provide the main directional instruction, and secondary reference markers that provide spatial context and accuracy verification. This segmentation allows the system to improve positioning accuracy through multiple markers while maintaining clear functional differentiation, preventing the display from becoming a confusing mixture of undifferentiated elements.
Solution Approach 2:
The patent applies different visual qualities and characteristics to different types of markers based on their specific functions. Navigation markers use distinctive visual properties to indicate turn directions and priorities, while reference markers use different properties to indicate spatial references and contextual information. This local differentiation of qualities helps the driver process information efficiently without being overwhelmed by uniform complexity.

AI summary
The invention relates to a method, a device and a computer-readable storage medium with instructions for controlling a display of an augmented-reality head-up display device for a motor vehicle. A graphics generator (10) generates a navigation marking for analogic contact on the display by means of the augmented reality head-up display device. A reference object can also be determined (11) by means of suitable methodology. The graphics generator (12) also generates a reference marking for a display using the augmented reality head-up display device. The navigation marking and the reference marking are finally outputted (13) for display by the augmented reality head-up display device to a control unit of the augmented reality head-up display device.
