Adaptive Occupant Output System for Impaired Drivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles fail to effectively communicate with hearing and vision impaired occupants, leading to discomfort and safety concerns due to lack of appropriate information dissemination about vehicle actions and external environments.
Innovation Solution
A system that includes an occupant output system with a processor to determine if an occupant is hearing or vision impaired, generating appropriate output modalities such as sign language animation, audio, or text based on vehicle context data, using sensors and biometric identification for personalized communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the vehicle uses standard audio-visual communication systems, then the information can be transmitted to general occupants, but hearing and vision impaired occupants cannot receive the information effectively
Solution Approach 1:
The system dynamically adapts communication modalities based on detected occupant impairments. Sensors detect vision or hearing impairments in real-time, and the system switches between audio, visual, and haptic feedback modes accordingly, ensuring information reaches all occupants effectively regardless of their sensory capabilities
Solution Approach 2:
The communication system is designed to perform multiple functions by supporting diverse output modalities including audio speakers, visual displays, and haptic feedback devices. This multi-functional approach ensures that the same information can be transmitted through different channels to accommodate various occupant needs
2Reliability
If the vehicle provides detailed information about external scenes and vehicle actions, then occupant awareness and comfort improve, but the system complexity and processing requirements increase
Solution Approach 1:
The information transmission system is segmented into multiple independent components including audio output devices, visual display devices, and haptic feedback devices. Each component handles specific types of information delivery, allowing the system to provide comprehensive feedback while distributing processing loads across separate modules rather than requiring a single complex system
Data Source
AI summary
Methods and systems for controlling an occupant output system associated with a vehicle are provided. The methods and systems receive vehicle or occupant context data from a source of vehicle context data, generate occupant message data based on the vehicle or occupant context data and determine if an occupant associated with the occupant output system is vision or hearing impaired. When the occupant is determined to be vision or hearing impaired, the methods and systems decide on an output modality to assist the occupant, and generate an output for the occupant on the output device, and in the output modality, based on the occupant message data.
