Vision Aid Selection Using Segmented Vision and Preference Tests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining vision aids tailored to an individual's needs are lengthy and cumbersome, requiring significant effort from both opticians and users, and often fail to provide suitable solutions for visually impaired individuals in various situations.
Innovation Solution
A device that conducts vision tests to determine optical, physical, and physiological characteristics, combined with user preferences, to select a group of vision aids that best meet the user's needs through a touch tablet interface, utilizing a series of tests for visual acuity, contrast, glare, and ergonomic considerations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to determine vision aids, then comprehensive vision assessment can be achieved, but the process becomes lengthy and cumbersome
Solution Approach 1:
The vision assessment process is segmented into multiple specialized tests (visual acuity, contrast sensitivity, glare, field of vision, color perception) that can be administered independently and systematically, allowing comprehensive evaluation to be broken down into manageable components that reduce overall process time
Solution Approach 2:
The device performs preliminary vision tests and collects user preference information before the final selection process, enabling the system to pre-filter suitable vision aids and present only relevant options, thereby reducing the time required for the complete assessment and selection process
2Adaptability or versatility
If comprehensive vision tests and user preferences are collected, then customized vision aid selection is achieved, but device complexity increases
Solution Approach 1:
The device integrates multiple functions into a single system: it performs various vision tests (visual acuity, contrast, glare, field of vision, color perception), collects user preference information, processes this data, and generates customized vision aid recommendations, thereby achieving high adaptability without proportionally increasing complexity
Solution Approach 2:
The device acts as an intermediary between the user's vision characteristics and the vision aid selection, automatically processing test results and preference data through algorithms that match users with suitable aids, thereby simplifying the complexity of customization for both the user and the optician
3Measurement precision
If multiple vision tests are conducted, then precise vision characteristics are determined, but the effort required for optician and user increases
Solution Approach 1:
The device enables users to independently complete vision tests and provide preference information without requiring constant optician intervention, with the system automatically processing results and generating recommendations, thereby maintaining measurement precision while significantly improving ease of operation
Solution Approach 2:
The device provides immediate feedback during testing and presents customized vision aid recommendations based on test results, allowing users to understand their vision characteristics and see how they translate into specific aid recommendations, thereby reducing the perceived effort while maintaining comprehensive assessment
