Vehicle Display Adaptation for Visual Impairment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with visual impairments face challenges in perceiving information on vehicle displays due to mismatched visual aids, leading to increased effort and safety risks for drivers and others on the road.
Innovation Solution
A motor vehicle display device with a memory unit to store visual requirements, an identification component to identify occupants, and a processing unit to assign and transfer these requirements to individually adjustable displays, allowing for electronic adaptation to visual acuity, long-sightedness, short-sightedness, astigmatism, and optical axis adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual aids (spectacles or contact lenses) are used to compensate for visual impairments, then visual capacity is partially restored, but they are not always matched satisfactorily to individual restrictions and may have detrimental influence
Solution Approach 1:
The patent replaces mechanical visual aids (spectacles, contact lenses) with an electronic/optical system that directly modifies the display output. The display device uses electronic processing to adapt the visual information according to stored individual visual requirements, eliminating the need for physical visual aids and their complex individual matching process.
Solution Approach 2:
The system creates a customized copy of the visual information tailored to each user's specific visual requirements. By storing individual visual parameters and applying them to generate personalized display outputs, the system replicates the effect of perfectly-matched visual aids without requiring physical accessories.
2Reliability
If standard displays are used in vehicles, then device complexity is low, but drivers with visual impairments experience increased effort and safety risks
Solution Approach 1:
The system performs preliminary adaptation by storing visual requirements of users in advance. When a user enters the vehicle, the display automatically retrieves and applies the pre-stored visual parameters, preparing the optimized display configuration before the user needs to view information, thereby eliminating real-time adjustment complexity.
Solution Approach 2:
The display device integrates multiple functions: standard display operation, user identification, visual requirement retrieval, and automatic adaptation. By combining these functions into a single system, the patent adds safety capabilities without proportionally increasing overall device complexity.
3Measurement precision
If displays are continuously adjusted to individual visual requirements, then perception clarity is improved, but system complexity and adjustment mechanisms increase
Solution Approach 1:
The display system performs self-adjustment by automatically applying stored visual requirements without manual intervention. The system serves itself by retrieving pre-stored user parameters and configuring the display accordingly, eliminating the need for complex manual adjustment mechanisms while maintaining high perception sharpness.
