Solution Overview

Problem

Existing user interfaces on devices like smartphones and smartwatches do not adequately accommodate visual impairments, as they fail to adapt to varying user needs for vision correction, leading to issues such as difficulty in reading small text and safety concerns when switching glasses during activities like driving.

Innovation Solution

A non-visual eyewear detector, such as a sensor using Bluetooth or RFID, determines the presence of eyewear and adjusts the user interface by changing the display of graphical objects in terms of number, nature, arrangement, and visual characteristics, including audio and vibration outputs, to accommodate different vision needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the display size is reduced to accommodate more content, then the quantity of information displayed is improved, but the readability for users with visual impairments deteriorates

Engineering Contradiction:
Improvequantity of informationVSAvoidreadability
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The system dynamically adjusts font size and icon dimensions based on detected eyewear presence. When eyewear is detected, the interface automatically increases the size of graphical objects and text to compensate for visual impairment, resolving the contradiction between displaying more content and maintaining readability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes display parameters (font size, icon size, spacing) in response to eyewear detection. This parameter adjustment allows the same display area to maintain both information density and readability by adapting visual characteristics based on user needs.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the user switches glasses during activities like driving, then the vision correction is improved, but the safety deteriorates due to the physical action required

Engineering Contradiction:
Improvevision correctionVSAvoidsafety
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system automatically detects eyewear presence and adjusts the interface without requiring user action. The automated detection and adaptation eliminate the need for manual glass switching, maintaining both vision correction and safety simultaneously.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from the eyewear detector to automatically adjust display characteristics. This closed-loop system continuously monitors eyewear status and adapts the interface in real-time, ensuring proper vision correction without requiring physical glass switching.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If traditional font size adjustment is used, then the readability is improved, but the adaptability to different eyewear conditions deteriorates

Engineering Contradiction:
ImprovereadabilityVSAvoidadaptability to eyewear
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system incorporates an eyewear detector that provides feedback about the user's visual correction needs. This enables automatic adaptation to different eyewear conditions (prescription glasses, sunglasses, reading glasses) rather than requiring manual font size adjustments, thereby improving both readability and adaptability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system creates a universal interface that automatically adapts to various eyewear types and conditions through detection and automatic adjustment. This multi-functional approach replaces manual adjustment mechanisms with an intelligent system that handles different visual impairment scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)
