Autonomous Vehicle Eye Display for Bidirectional Pedestrian Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicles face challenges in creating eye contact with pedestrians and others while maintaining a low-cost configuration, especially when the vehicle's front and rear sides are not predetermined, and in communicating safety messages to individuals who do not understand the language used.
Innovation Solution
A moving body management system that includes a first body with wheels for travel, a second body attachable to and detachable from the first body, and a display circuit facing the outer side of the first body to display schematic patterns of eyes, allowing for eye contact and rich expressions at a lower cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanism for moving left and right eyes is provided to enable eye contact with rich expressions, then the expression capability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent uses a display device to create a visual copy or representation of eyes rather than using actual mechanical eye structures. The display shows eye patterns that can change expression through software control, eliminating the need for complex mechanical moving parts while achieving the same communicative function.
Solution Approach 2:
The patent replaces the mechanical eye-moving mechanism with an electronic display system. Instead of physically moving eye components through motors and linkages, the system uses a display screen to render eye images that can move and express emotions through digital manipulation, substituting mechanical complexity with electronic simplicity.
2Adaptability or versatility
If mechanisms for moving eyes are provided at both ends of the vehicle body to enable eye contact in bidirectional autonomous vehicles, then the eye contact capability is improved, but the manufacturing cost increases
Solution Approach 1:
The display device serves multiple functions: it displays eye patterns for communication, shows navigation information, presents safety messages to pedestrians, and can adapt its content based on the vehicle's orientation and environment. This multi-functionality eliminates the need for separate eye mechanisms at both ends of the vehicle.
Solution Approach 2:
The system dynamically adapts the display content and orientation based on the vehicle's current direction and context. The eye patterns can be oriented toward different directions as needed, and the display can switch between showing eyes, safety messages, or other information based on real-time requirements, making the system flexible without requiring duplicate hardware.
3Loss of information
If safety messages are written in a specific language on the display, then the message clarity is improved, but the accessibility to non-speakers worsens
Solution Approach 1:
The display system dynamically changes the language and content shown based on detection of the pedestrian's language or the context of the situation. The system can switch between multiple languages and message types (eye contact mode, safety message mode, navigation mode) to ensure effective communication with diverse users.
Solution Approach 2:
The system incorporates feedback mechanisms to detect the language or characteristics of nearby pedestrians and adjusts the displayed message accordingly. This feedback loop allows the system to select the most appropriate language and message type to ensure understanding while maintaining clear communication.

AI summary
A moving body is configured to perform autonomous operation. The moving body includes: a first body including at least one wheel and configured to travel by the at least one wheel; a second body attachable to and detachable from the first body; and a display circuit arranged to face an outer side of the first body. The display circuit is configured to display at least a first schematic pattern of a first eye and a second schematic pattern of a second eye.
