Solution Overview

Problem

Current human-machine interaction methods lack the ability to truly simulate natural interactive behaviors, resulting in a poor user experience due to inadequate simulation of gesture controls.

Innovation Solution

A method that utilizes a 3D display system with a sight tracking camera and a gesture detection camera to detect eye gaze and hand interactions, allowing for the rendering of high-definition visuals when the user's eyes and hand engage with virtual objects, while reducing bandwidth by rendering other areas in low definition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If gesture control methods are used to control content on the display screen, then the interaction method is natural and comfortable, but the current human-machine interaction mode has poor user experience because it does not truly simulate people's interactive behaviors

Engineering Contradiction:
Improveinteraction naturalnessVSAvoiduser experience quality
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines eye tracking technology with gesture recognition technology to create a unified interaction system. The eye tracking camera detects gaze direction while the gesture camera detects hand movements, and these two detection systems are merged to control the 3D display content, enabling a more complete simulation of natural human interaction behaviors that neither system could achieve alone

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an interaction processing device as an intermediary that receives detection results from both the eye tracking camera and gesture camera, processes this information according to preset interaction logic, and generates control signals for the 3D display. This intermediary coordinates the two detection systems and translates natural human behaviors into meaningful control actions

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If high definition rendering is applied to the entire 3D view, then the visual quality is high, but the display bandwidth requirement increases significantly

Engineering Contradiction:
Improvevisual qualityVSAvoiddisplay bandwidth
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent applies different rendering qualities to different regions of the 3D display based on user attention. The interaction processing device determines a first region around the eye gaze region where high definition rendering is applied, while other regions receive low definition rendering. This local quality differentiation maintains visual quality in the important area while significantly reducing overall bandwidth requirements

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent makes the high definition rendering region dynamic by continuously tracking the user's eye gaze position. As the user moves their eyes, the first region where high definition rendering is applied shifts accordingly, ensuring that high visual quality is always provided in the area the user is currently viewing while adapting to changing attention patterns

Inventive Principle:
Principle #15Dynamics
