Solution Overview

Problem

Patients with visual field disorders due to conditions like glaucoma, macular degeneration, and diabetic retinopathy experience impaired visual abilities, and current treatments such as drugs and surgery are often ineffective in curing these disorders.

Innovation Solution

A device and method utilizing visual perception learning through a display module that provides targeted visual perception tasks, including stimulus objects and tasks at specific positions to improve visual abilities by repetitive training.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If drugs or surgery are used to treat visual field disorders, then treatment is provided, but the disorders are not cured and visual ability is not improved

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidvisual ability improvement

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent changes the treatment approach from passive medical intervention (drugs/surgery) to active neural stimulation through visual perception tasks. By modifying the stimulation parameters (spatial frequency 0.1-1 cycle/degree, temporal frequency 10-50 Hz, contrast ratios), the system induces plastic changes in the visual cortex to improve visual field function.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical/chemical treatment systems (drugs injection, surgical intervention) with a neurostimulation system using visual perception learning. This substitution uses optical stimuli and neural plasticity mechanisms instead of pharmacological or surgical approaches.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If visual perception tasks are displayed continuously, then training effectiveness improves, but patient fatigue and attention loss increase

Engineering Contradiction:

Improvetraining effectivenessVSAvoidpatient comfort

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The patent implements periodic action by displaying stimulus objects at specific temporal frequencies (10-50 Hz) and using intermittent presentation rather than continuous display. The stimulus objects are presented in cycles with specific durations and intervals, maintaining training effectiveness while preventing patient fatigue.

Inventive Principle:

Principle #19Periodic action

3Area of stationary object

If stimulus objects are displayed at multiple positions simultaneously, then visual field coverage improves, but task discrimination difficulty increases

Engineering Contradiction:

Improvevisual field coverageVSAvoidtask discrimination difficulty

Core Design Contradiction:

Area of stationary objectVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies segmentation by dividing the visual field training into discrete stimulus positions and sequential presentations. Instead of displaying multiple stimuli simultaneously across the entire visual field, the system segments the stimulus presentation into controlled positions and time intervals, making task discrimination easier while maintaining comprehensive visual field coverage.

Inventive Principle:

Principle #1Segmentation

AI summary

Disclosed is a device for providing visual perception training including a display module, and a controller for acquiring at least one target area corresponding to at least one of a first cell of a left eye visual field map and a second cell of a right eye visual field map, and providing a visual perception task to the at least one target area. In the providing of the visual perception task, the controller displays, through the display module, a task object for receiving a response of a patient and fixing a central visual field of the patient, displays, through the display module, at least one stimulus object at at least one stimulus position corresponding to the at least one target area, and acquires the response of the patient related to the task object.
