Vehicle Window AR Notifications for Autonomous Intent Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack effective means to communicate with passengers, delivery recipients, and other stakeholders, as they cannot verbally convey information about the vehicle's state, intent, or route, which is crucial for navigation and passenger guidance.
Innovation Solution
An augmented reality notification system that uses a display control system to detect events related to the vehicle's state, intent, and environment, generating images with text and graphics information to be displayed on windows, enabling communication with users outside the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If autonomous vehicles use traditional communication methods (audio/visual warnings), then basic safety information can be conveyed, but effective communication with passengers and stakeholders about vehicle state, intent, and route is insufficient
Solution Approach 1:
The patent uses augmented reality displays on vehicle windows as an intermediary medium to communicate vehicle state, intent, and route information to passengers and stakeholders. The AR interface acts as a mediator between the autonomous vehicle's internal systems and external users, providing intuitive visual feedback without requiring complex audio-visual warning systems or additional communication hardware.
Solution Approach 2:
The patent transitions from traditional 2D audio-visual displays to augmented reality that overlays information directly onto the user's field of view through window displays. This dimensional shift allows information to be presented in the context of the user's environment, improving comprehension of vehicle intent and route without increasing system complexity.
2Loss of information
If augmented reality displays are implemented on vehicle windows, then communication of vehicle state and intent is enhanced, but energy consumption and system complexity increase
Solution Approach 1:
The patent integrates augmented reality display functionality into existing vehicle window structures, allowing the same window surface to serve both its traditional function and as an information display medium. This multi-functionality approach enables effective communication of vehicle state and intent while avoiding the need for separate display hardware that would increase energy consumption.
3Ease of operation
If multiple display surfaces are used throughout the vehicle, then information accessibility to all users is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements augmented reality displays on specific vehicle windows strategically positioned to provide information to different user groups (passengers, pedestrians, other drivers). Each window display is customized to the local context and user needs, providing relevant information without requiring comprehensive displays on all vehicle surfaces, thus balancing accessibility with system complexity.
