Solution Overview

Problem

Existing text display solutions in augmented reality are static, leading to rigid and monotonous display effects.

Innovation Solution

A method and apparatus that involve acquiring a real scene image, invoking motion track data for texts, and applying dynamic special effects to the to-be-displayed text, which is then displayed on the real scene image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If static text display is adopted in augmented reality, then the display implementation is simple, but the text display effect becomes rigid and monotonous

Engineering Contradiction:
Improvedisplay implementation complexityVSAvoidtext display effect variety
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent applies motion track data to transform static text into dynamic text displays with various movements such as fading in, sliding, rotating, and scaling. The text elements are animated along predefined motion tracks to create lively and engaging augmented reality experiences, directly resolving the contradiction between implementation simplicity and display effect variety.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If dynamic special effect processing is applied to text, then the text display effect becomes more vivid, but the processing complexity increases

Engineering Contradiction:
Improvetext display effect vividnessVSAvoidprocessing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent pre-defines motion tracks and animation parameters for text elements before rendering. By preparing motion data in advance and storing it for reuse, the system reduces real-time processing complexity while maintaining vivid dynamic display effects. The motion tracks are predetermined paths and transformations that can be applied efficiently during rendering.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If motion track data is invoked for dynamic text processing, then the text display becomes more engaging, but the data processing time increases

Engineering Contradiction:
Improvetext display engagementVSAvoiddata processing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent uses motion track data that can be reused across multiple text elements and display instances. Instead of generating unique animation data for each text element, the system copies and applies predefined motion tracks to different texts, significantly reducing data processing time while maintaining engaging dynamic effects throughout the augmented reality scene.

Inventive Principle:
Principle #26Copying
