Vehicle Behavior Support System Handling Uncertain Passenger Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing behavior support systems do not effectively account for uncertain information obtained in vehicles, such as conversations and gestures, when multiple passengers are present, leading to inadequate behavior support.
Innovation Solution
A behavior support system that includes units to obtain, analyze, and output support information based on uncertain information from passengers in a vehicle, using helmets or in-vehicle displays to provide relevant information, such as conversation topics or navigation guidance, tailored to individual preferences and interests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If behavior support systems use conventional information processing methods, then system complexity is reduced, but the ability to handle uncertain information from multiple passengers deteriorates
Solution Approach 1:
The patent introduces an information processing unit that acts as an intermediary between information acquisition and behavior support. This unit specifically handles uncertain information by extracting meaningful patterns from noisy data sources like conversations and gestures, mediating between the raw uncertain information and the behavior support functions without requiring complete system redesign
Solution Approach 2:
The system segments information processing into distinct units: information acquisition units for different data sources, an information processing unit for handling uncertain information, and behavior support units for specific functions. This segmentation allows each unit to specialize in handling particular types of information while maintaining overall system manageability
2Measurement precision
If the system processes information from multiple passengers, then behavior support accuracy improves, but information uncertainty increases
Solution Approach 1:
The system employs feedback mechanisms where the information processing unit continuously refines its interpretation of uncertain information based on patterns detected in real-time data from multiple passengers. This feedback loop allows the system to improve behavior support accuracy by learning from ongoing interactions while managing the inherent uncertainty through iterative processing
Solution Approach 2:
The information processing unit serves as a mediator that receives uncertain information from multiple sources, processes it to extract meaningful patterns, and delivers refined information to behavior support units. This intermediary processing reduces information uncertainty while maintaining multi-passenger data inputs
3Ease of operation
If the system provides personalized support to each passenger, then behavior support effectiveness improves, but device complexity increases
Solution Approach 1:
The system divides behavior support functionality into separate behavior support units, each dedicated to supporting specific passengers or passenger groups. This segmentation enables personalized support for each passenger while keeping the overall device complexity manageable through modular architecture and specialized processing for each unit
Data Source
AI summary
A behavior support system that implements behavior support taking account of uncertain information obtained in a vehicle is provided. Uncertain information containing at least a conversation between passengers is obtained and analyzed. Support information for supporting behaviors of the passengers is obtained based on a result of the analysis, and the obtained support information is output to a helmet of at least one of a first passenger and a second passenger. New information regarding a word for the second passenger is obtained as the support information, based on the word obtained from the second passenger, and the support information is output to the first passenger so that the new information is provided from the first passenger to the second passenger.
