Dynamic AR HUD Icon Visibility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality head-up displays in vehicles often result in relevant safety-critical information being concealed due to overlap with other icons, leading to reduced visibility for drivers.
Innovation Solution
A device and method that dynamically adjust the visibility of notice icons in a vehicle by determining an output configuration based on vehicle and notice data, using an input interface to receive data and an analysis unit to generate control commands for an AR display device, allowing for increased visibility of both safety-critical and non-safety-critical information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If parallel display with plane concept is used to show multiple notices simultaneously, then the quantity of information displayed is improved, but the visibility of individual notices deteriorates due to overlap concealment
Solution Approach 1:
The patent applies dynamics by making the display configuration changeable over time. The system dynamically adjusts the display parameters (transparency, size, position) of notice icons based on their priority and the current display situation. This allows the display to adapt between showing multiple notices simultaneously and ensuring individual notice visibility, resolving the contradiction between quantity of information and visibility.
Solution Approach 2:
The patent changes display parameters such as transparency, size, and position of notice icons to resolve the overlap problem. By adjusting these parameters dynamically based on notice priority and spatial relationships, the system can display multiple notices while preventing complete concealment of any single notice, thus balancing information quantity with individual visibility.
2Reliability
If safety-critical information is prioritized with highest priority management, then the reliability of critical information display is improved, but the quantity of concurrent information displayed deteriorates
Solution Approach 1:
The patent applies local quality by assigning different display characteristics to different regions or layers of the display based on notice priority. Safety-critical notices receive enhanced display properties (higher priority, different transparency levels, prominent positioning) while less critical notices have reduced properties. This allows concurrent display of multiple notices with differentiated visibility, maintaining reliability of critical information while increasing overall information quantity.

AI summary
The disclosure relates to a contact-analogous head-up display, in particular an augmented reality head-up display, which places information in direct contact with the environment. Contrary to conventional head-up displays, the items of information appear as part of the environment. The subject matter of the disclosure relates to a dynamic improvement of the visibility of concealed AR elements in situations in which several elements are displayed in parallel.
