Solution Overview

Problem

Current methods for providing augmented reality (AR) services in communication systems do not effectively consider the user equipment's ambient environment, leading to suboptimal AR content delivery that is not tailored to the user's position and surroundings.

Innovation Solution

A method and device that generate ambient environment information based on the user equipment's surroundings, establish a session with an application server to receive an AR service description, and transmit this information to the server to receive tailored AR content, ensuring the AR service is optimized for the user's environment and position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional AR service delivery methods are used without considering ambient environment, then the service can be provided with basic functionality, but the AR content relevance and realism to user context deteriorates

Engineering Contradiction:
ImproveAR content adaptability to ambient environmentVSAvoidsystem complexity for environment assessment
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary assessment of the ambient environment before delivering AR content. The server evaluates environment information (such as location, surrounding objects, contextual data) in advance and prepares appropriate AR content accordingly, rather than reacting to environmental changes during content delivery. This allows the system to adapt AR services to the ambient environment without adding complex real-time processing requirements during content transmission.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If AR service is tailored to user position and environment, then the AR content realism and contextual relevance improves, but the information processing requirements and communication overhead increases

Engineering Contradiction:
Improveenvironmental context informationVSAvoidcontent delivery efficiency
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The system extracts only the essential environment information needed for AR content delivery from the complete ambient context. Rather than transmitting or processing all available environmental data, the server identifies and utilizes key parameters (such as user position, relevant surrounding objects, or critical contextual factors) to generate appropriate AR content. This extraction approach maintains AR content relevance while minimizing communication overhead and processing requirements.

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If comprehensive ambient environment information is collected, then the AR service accuracy and user experience improves, but the data transmission load and processing time increases

Engineering Contradiction:
Improveenvironment assessment accuracyVSAvoidservice setup time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system implements partial environment assessment by collecting and processing only the necessary portion of ambient information required for effective AR service delivery. Rather than comprehensively analyzing all environmental factors, the server determines which environmental parameters are most relevant to the specific AR content and user context, then focuses assessment efforts on those specific factors. This partial assessment approach achieves sufficient accuracy for high-quality AR experiences while minimizing data collection and processing time.

Inventive Principle:
Principle #16Partial or excessive action
