Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality and optic control systems, such as HUDs and 3D displays, face limitations in providing realistic and adaptive visual experiences, particularly in dynamic environments like vehicles, where brightness and glare can cause discomfort and safety issues.
Innovation Solution
A variably directionally light-blocking, light-generating, and light-transmitting screen system with a matrix of angle-directable, shiftable pixels that adjusts light levels and direction to create enhanced, realistic 3D objects and reduce glare, using sensors to build an object structure library and apply it to real-time environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional HUDs reflect light off semi-transparent surfaces to create information read-out, then vehicle and navigation information is displayed in the pilot's field of vision, but brightness and glare cause discomfort and safety issues
Solution Approach 1:
The patent applies local quality by using a matrix of individually controllable light-emitting elements (such as LEDs or micro-displays) arranged in a grid pattern on the windshield. Each element can independently adjust its light emission intensity and direction, allowing different regions of the windshield to have different optical properties. This enables the system to display information with appropriate brightness in specific areas while maintaining transparency and minimizing glare in other areas, thus resolving the contradiction between information visibility and pilot comfort.
Solution Approach 2:
The patent implements dynamics by making the light-emitting elements adjustable and reconfigurable in real-time. The system can dynamically change the intensity, color, and direction of light emitted by each matrix element based on environmental conditions, pilot position, and information priority. This dynamic adaptability allows the HUD to optimize brightness for visibility while simultaneously reducing glare through real-time adjustment, resolving the contradiction between illumination intensity and harmful glare effects.
2Measurement precision
If 3D displays use stereoscopic techniques with headsets to create different perspective images, then depth perception is improved, but device complexity and user comfort are reduced
Solution Approach 1:
The patent merges the display function directly into the windshield structure itself, combining the transparent surface with integrated light-emitting matrix elements. This eliminates the need for separate headset devices by making the windshield the display medium. The system achieves 3D depth perception through spatial arrangement of light elements and optical effects created directly on the windshield, thereby reducing device complexity while maintaining depth perception accuracy.
Solution Approach 2:
The patent applies universality by making the windshield serve multiple functions simultaneously: it acts as both the transparent protective surface and the display medium for information presentation. The matrix of light-emitting elements integrated into the windshield enables the same surface to provide both structural function and visual information display, including 3D depth perception capabilities, thereby eliminating the need for additional specialized headset equipment.
3Object-affected harmful factors
If light-blocking materials are used to reduce glare, then pilot comfort is improved, but visibility of the environment surrounding the vehicle is reduced
Solution Approach 1:
The patent segments the windshield into a matrix of individually controllable light-emitting elements. This segmentation allows the system to apply glare reduction selectively to specific regions where information is displayed, while leaving other regions fully transparent for environmental visibility. Each matrix element can independently block or transmit light based on its function, enabling localized glare control without compromising overall environmental visibility.
Solution Approach 2:
The patent implements dynamic control where each matrix element can adjust its light-blocking properties in real-time. When displaying information, elements emit controlled amounts of light; when not displaying information, they remain transparent. This dynamic adaptability allows the system to reduce glare only when and where needed for information display, while maintaining full environmental visibility at all other times, thus resolving the contradiction between glare reduction and environmental visibility.

AI summary
New augmented reality display systems are provided, some of which incorporate “shifted-reality” techniques. In some embodiments, an augmented reality display system includes a matrix of light-augmenting pixels within a variable-transmission, semi-transparent screen (e.g., an augmented reality headset, comprising a semi-transparent screen) and creates redirected, attenuated and augmented light and shading to form and alter virtual objects. In some embodiments, a plurality of angle-alterable, shiftable sources (e.g., light-focusing and -directing pixels), aids in creating virtual objects of greater realism than conventional 3D imaging methods, and aids in reducing the appearance of other objects or conditions. In some aspects, existing images and objects may be shifted in perspective for an observer, and enhanced and overlaid with effects and demonstrative information related to them and a surrounding environment. In other aspects, the system builds and accesses an object structure and materials library and object inventory, enriching a user's augmented reality experience.
