Solution Overview

Problem

Current mobile terminals lack an intuitive and efficient method for users to access and manage numerous content items and applications, particularly in providing a user-friendly interface for 3D image display and manipulation.

Innovation Solution

A method and apparatus that adjust the depth of 3D objects displayed on a mobile terminal by controlling the disparity between left and right objects, utilizing attribute information such as usage frequency and user input to intuitively represent object attributes, allowing users to recognize and interact with content items and applications more effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a 3D image display function is added to mobile terminals, then depth perception and visual appeal are improved, but device complexity increases

Engineering Contradiction:
Improvevisual appealVSAvoiddevice complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent applies dimensionality change by transitioning from traditional 2D flat display to 3D display with depth perception. The controller adjusts disparity values for left and right images to create depth effects, allowing objects to appear closer or farther from the user. This adds a depth dimension to the visual experience while maintaining the same physical display hardware.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent implements multi-functionality by enabling the display module to operate in multiple modes: 2D display mode for standard content and 3D display mode for depth-enhanced content. The controller can dynamically switch between these modes and adjust disparity parameters, making the same hardware serve both 2D and 3D display purposes without requiring separate dedicated components.

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

2Ease of operation

If touch input processing is enhanced for 3D manipulation, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies self-service by enabling users to directly manipulate 3D objects through natural touch gestures on the touchscreen. The controller processes touch coordinates and adjusts disparity values based on user input, allowing users to independently control depth perception and object positioning without requiring complex external controls or specialized input devices.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent uses the touchscreen as an intermediary between the user and the 3D display function. Touch coordinates from user interaction are translated by the controller into disparity adjustments, serving as a mediator that converts simple touch inputs into complex 3D manipulation effects without requiring direct complex control mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)
