Windshield AR Overlay for Peripheral Hazard Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers have difficulty detecting roadside objects in their peripheral vision without diverting attention from the road ahead, which can lead to accidents, as these objects may be close to the lane or moving into the vehicle's path, and existing systems do not provide real-time video and importance analysis for such objects.
Innovation Solution
A computer-based system using front and side cameras to detect roadside objects in the driver's mid and far peripheral view, analyze their importance using image analytics, and display them semi-transparently on the windshield with color-coded alerts, allowing the driver to maintain focus on the road while being aware of potential hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers focus straight ahead to avoid striking objects, then collision avoidance is improved, but awareness of roadside objects in peripheral view deteriorates
Solution Approach 1:
The patent introduces an augmented reality display system as an intermediary that captures peripheral view information through cameras and presents it as semi-transparent overlays on the windshield. This mediator allows drivers to maintain forward focus while receiving processed information about roadside objects without directly viewing them, thus resolving the contradiction between collision avoidance and peripheral awareness.
Solution Approach 2:
The system transforms two-dimensional camera images into three-dimensional spatial context by projecting roadside objects onto the windshield at their actual spatial locations. This dimensional transformation allows drivers to perceive depth and position information naturally, integrating peripheral awareness into the existing forward-viewing paradigm without requiring head movements.
2Loss of information
If drivers check peripheral vision by moving heads, then awareness of roadside objects is improved, but attention to road ahead deteriorates
Solution Approach 1:
The augmented reality display acts as an intermediary that delivers peripheral view information directly to the driver's central field of view. Instead of requiring head movements to scan the periphery, the system mediates information transfer by presenting processed peripheral data as overlays that naturally attract attention without requiring physical orientation changes, thus maintaining both peripheral awareness and forward attention.
3Loss of information
If all detected objects are displayed to the driver, then completeness of information is improved, but driver distraction increases
Solution Approach 1:
The patent applies local quality by differentiating the display characteristics of various roadside objects based on their relevance. High-priority objects (e.g., pedestrians, animals, vehicles) are displayed with prominent visual characteristics such as larger size, brighter colors, or pulsing effects, while low-priority objects are displayed more subtly or omitted entirely. This localized differentiation ensures that complete information is provided without uniformly distracting the driver.
Solution Approach 2:
The system uses color changes to encode object priority and type information. Different colors indicate different levels of urgency or object categories, allowing drivers to quickly assess situations without detailed analysis. For example, red may indicate high-priority hazards requiring immediate attention, while green or blue indicates lower-priority information, thus reducing distraction while maintaining information completeness.

AI summary
A display of roadside objects on a vehicle windshield within a primary field of view of a driver, with an indication of a level of importance of the object is provided. A method includes: detecting, by a computer device, a roadside object in a vehicle driver's peripheral view; analyzing, by the computer device, the detected roadside object to assign a level of importance to the object based on predefined levels of importance; and displaying, by the computer device, the roadside object as a semi-transparent object in a display area of a windshield of the vehicle with an indication of the level of importance of the object.
