Vehicle AR Windshield Display With Gaze-Based Clearing Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems in vehicles can cause driver distraction and narrow the free field of view, obstructing the driver's unobstructed view of the surroundings, particularly with increasing information density.
Innovation Solution
A method for displaying augmented reality information on a vehicle windshield that detects the occupant's viewing direction, defines a clearing area around it, and adapts information display to avoid obstruction, ensuring safety-relevant info is displayed in this area while non-essential info is outside or dimmed, with the option for enlarged display of relevant objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If augmented reality information is displayed on the windshield with increasing information density, then the amount and type of information available to the driver increases, but driver distraction increases and the free field of view is narrowed
Solution Approach 1:
The patent applies local quality by creating a clearing area with different display properties than the surrounding regions. The clearing area around the occupant's viewing direction has reduced or no augmented reality information, while other areas can display information at normal density. This spatial differentiation of display quality allows information to be available where needed while maintaining clear viewing areas where safety is critical.
2Adaptability or versatility
If augmented reality information is displayed on the windshield, then driving assistance functions are enhanced, but the driver's unobstructed view of the surroundings is obstructed
Solution Approach 1:
The patent implements dynamics by making the clearing area adaptive and movable rather than static. The clearing area is positioned based on the detected occupant viewing direction, so it dynamically adjusts its location on the windshield as the occupant's gaze changes. This dynamic positioning ensures that the clearing area always protects the most relevant portion of the driver's field of view while allowing augmented reality information to be displayed in other areas.

AI summary
Preferably, after a displaying of the ambient object, a renewed detection of the occupant's current viewing direction is temporarily deactivated or can be deactivated (also for a limited time or permanently switchable). This allows the occupant to view and evaluate the displayed augmented reality information in detail. Deactivation can also be performed, for example, by a digital or analog switching element, via gesture or voice control, and depending on the situation (examples of corresponding situation-dependent parameters are listed above) for a certain time. On the other hand, however, a call-up control of the display can also be achieved via the deactivation function. A displaying of the enlarged and/or magnified surrounding object takes place accordingly always only if the function was activated accordingly before. In this respect, a time-limited or general activation of the expanded and/or magnified display of environment objects can also be performed.
