Innovation Solution

A method and display module that utilizes an eye tracker and processor to automatically track the user's eye position, determine a first coordinate point, and generate a vector through objects in a three-dimensional image, allowing for the determination of a second pointer position based on defined values, enabling intuitive manipulation of objects within the image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional three-dimensional display requires complex operating instructions or manual image processing to select specific spatial position coordinates, then the system can perform precise selection, but the ease of operation deteriorates

Engineering Contradiction:

Improvespatial position coordinate selection precisionVSAvoiduser operation convenience

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical operations (mouse clicking, keyboard input, manual dragging) with automatic eye-tracking based selection. The eye tracker detects user gaze position and automatically determines the corresponding spatial coordinate in the three-dimensional image, eliminating the need for complex manual input instructions while maintaining precise coordinate selection capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service operation by automatically interpreting user intent through eye tracking. Instead of requiring users to explicitly input selection commands, the system autonomously determines spatial coordinate selection based on eye position and gaze direction, allowing users to simply look at the target object to initiate selection.

Inventive Principle:

Principle #25Self-service

2Measurement precision

If manual image processing is required to select spatial coordinates, then processing accuracy can be controlled, but the processing time and complexity increase

Engineering Contradiction:

Improvecoordinate selection accuracyVSAvoidimage processing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The eye tracking system continuously monitors eye position in advance, preparing the coordinate selection function before the user actually needs to select a coordinate. The system pre-processes the mapping between eye position and three-dimensional spatial coordinates, so when selection is needed, the result is immediately available without requiring time-consuming manual measurement or processing.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent substitutes manual coordinate measurement and selection processes with automatic computer vision-based eye tracking. The system automatically extracts eye position data and converts it to corresponding three-dimensional spatial coordinates through pre-established geometric models, eliminating time-consuming manual operations while maintaining high accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If complex operating instructions are used for three-dimensional image manipulation, then the system functionality is comprehensive, but the ease of operation deteriorates

Engineering Contradiction:

Improvethree-dimensional image manipulation capabilityVSAvoidoperation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The eye tracking system serves as a universal input mechanism that can control multiple functions of three-dimensional image manipulation. A single eye tracking interface enables various operations including coordinate selection, object identification, and spatial navigation, eliminating the need for multiple separate input devices and complex instruction sets while maintaining comprehensive system functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The eye tracking system acts as an intermediary between the user and the three-dimensional image system. Instead of requiring users to directly interact with complex interfaces and instructions, the eye tracker translates simple gaze movements into appropriate system commands, serving as a mediating layer that simplifies the user interface while preserving full system capability.

Inventive Principle:

Principle #24Intermediary (Mediator)
