Dual-Eye Display Transparency for Focused Visual Acuity Training

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing visual training methods that change the view for each eye make it difficult to concentrate on the work object and can make it stand out due to contrast, brightness, or darkness adjustments.

Innovation Solution

A visual function system with separate display devices for each eye, controlling the transparency of objects displayed on these devices differently to enhance training, particularly for amblyopia, by adjusting transparency based on eye acuity and difficulty levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the view of the entire space is changed for each eye using a headset, then visual training can be provided, but it becomes difficult to concentrate on the work object that should be focused on

Engineering Contradiction:

Improvevisual training capabilityVSAvoidconcentration on work object

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies local quality by making different parts of the displayed image have different transparency characteristics. Specifically, the work object region is set with lower transparency (higher visibility) while other regions have higher transparency (lower visibility), allowing the user to concentrate on the work object while still receiving visual training through differential transparency control for each eye

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent segments the displayed image into multiple regions with different transparency settings. The image is divided into a work object region and other regions, with each region assigned different transparency values for the right and left eyes, enabling focused attention on the work object while maintaining visual training effectiveness

Inventive Principle:

Principle #1Segmentation

2Measurement precision

If the contrast, brightness, or darkness of the work object is changed, then the object stands out more, but it makes it difficult to concentrate on the work object

Engineering Contradiction:

Improveobject visibilityVSAvoidconcentration on work object

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

Instead of changing contrast, brightness, or darkness of the entire work object, the patent applies local quality by adjusting transparency specifically for different eye views. The work object is made more visible through differential transparency control between right and left eyes rather than through brightness or contrast adjustments, allowing the object to stand out for training purposes while maintaining natural appearance and concentration

Inventive Principle:

Principle #3Local quality

AI summary

[Technical Problem] To enable visual function training. [Solution to Problem] A visual function training system comprising: a first display device configured to display an image to one eye of a user; a second display device configured to display an image to an opposite eye of the user; and a display control unit configured to control an object to be operated by the user, which is displayed on the first and second display devices, to have different transparencies on the first and second display devices.
