In-Vehicle AR Outdoor Displays for Low-Visibility Driver Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in low visibility conditions, difficulty in locating emergency vehicles, and decreased safety due to drowsiness, which existing technologies have not adequately addressed.
Innovation Solution
The implementation of Augmented Reality (AR) systems in vehicles that obtain contextual data, determine the position and field of view of occupants, and overlay occupant-specific images onto outdoor displays to provide enhanced information and safety alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional driving information systems are used, then basic navigation and warning functions are provided, but drivers cannot receive personalized information or enhanced safety alerts in low visibility conditions
Solution Approach 1:
The system segments information delivery by creating separate processing channels for different occupant types (driver vs. passenger) and different information categories (safety alerts vs. personalized content). This is achieved through separate detection modules for occupant position and state, and distinct overlay mechanisms that target specific regions of the outdoor display based on occupant role and condition.
Solution Approach 2:
The system performs preliminary detection of occupant state (drowsiness, attention level) and position before critical events occur. By continuously monitoring occupant conditions in advance and pre-positioning relevant information on the outdoor display, the system ensures that safety-critical information is already visible and personalized content is ready for delivery when needed, reducing reaction time in emergency situations.
2Adaptability or versatility
If outdoor displays show generic information, then all occupants receive the same content, but drivers cannot receive personalized safety alerts or relevant information tailored to their specific needs
Solution Approach 1:
The outdoor display serves multiple functions simultaneously: it acts as a navigation aid, a safety warning system, a personalized information delivery platform, and an augmented reality interface. The same display hardware delivers both generic safety information and personalized content based on detected occupant state, eliminating the need for separate specialized devices while maximizing the utility of the existing outdoor display infrastructure.
Solution Approach 2:
The AR viewer acts as an intermediary device that bridges the gap between the outdoor display and the occupant's visual field. Rather than modifying the outdoor display hardware itself, the system uses the AR viewer to capture, process, and overlay personalized information on top of the generic outdoor display content, allowing personalized information delivery without complicating the core display system.
3Loss of information
If the system monitors multiple occupant parameters, then personalized information can be delivered, but the processing complexity and data requirements increase
Solution Approach 1:
The system applies different levels of monitoring and processing to different occupants based on their role and detected state. Drivers receive enhanced monitoring for safety-critical parameters (drowsiness, attention) while passengers may receive less intensive monitoring. Information processing is localized to only those parameters relevant to each occupant's current state and position, reducing overall computational complexity while maintaining personalized delivery.

AI summary
The following generally relates to using Augmented Reality (AR) to enhance the in-vehicle experience. In some examples, AR techniques are applied to provide AR indications of vehicle safety indicia to alert vehicle occupants to information that may not otherwise be perceptible. In other examples, AR techniques are applied to provide emergency vehicle warnings to improve the likelihood of safe responses thereto. In yet other examples, AR techniques are applied to generated personalized outdoor displays, for example, to ameliorate conditions that may impair safe operation of a vehicle.
