Solution Overview

Problem

Current virtual reality and augmented reality technologies lack an effective paradigm for interaction and selection of virtual objects based on environmental light settings, such as color and brightness, which limits user control and context-aware rendering.

Innovation Solution

A method that obtains and compares light parameters with a virtual object database to select and render virtual characters on an image rendering device, allowing users to control the rendering of virtual objects based on current light settings, location, time, and type of light source, enabling context-aware and user-defined interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If virtual objects are rendered based on environmental lighting information, then context-aware rendering and user interaction are enhanced, but device complexity and processing requirements increase

Engineering Contradiction:
Improvecontext-aware renderingVSAvoidprocessing requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system pre-processes and stores virtual objects in a database with associated lighting parameters before runtime. During operation, it only needs to retrieve and match objects based on current environmental lighting conditions, significantly reducing real-time processing requirements while maintaining context-aware rendering capabilities

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically detects environmental lighting parameters (color temperature, intensity, direction) and autonomously selects appropriate virtual objects from the database without requiring manual user configuration or complex real-time rendering calculations, reducing both device complexity and processing load

Inventive Principle:
Principle #25Self-service

2Measurement precision

If a database of virtual objects with lighting parameters is implemented, then selection accuracy and user control improve, but system complexity and memory requirements increase

Engineering Contradiction:
Improveselection accuracyVSAvoidmemory requirements
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The database stores virtual objects with lighting parameters organized by specific lighting conditions (color temperature ranges, intensity levels, directional angles). The system queries only the relevant subset of objects matching current environmental parameters, improving selection accuracy while minimizing memory access requirements and effectively managing storage needs through selective organization

Inventive Principle:
Principle #3Local quality
