Virtual Object Representation Control for Context-Aware 2D and 3D CGR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer-generated reality (CGR) environments lack robust functionality for controlling the representation of virtual objects based on their location and use context, as well as the concurrent display of two-dimensional (2D) and three-dimensional (3D) representations of these objects.
Innovation Solution
The system adapts the representation of virtual objects within CGR environments based on the use context of their location, allowing for dynamic changes in representation when moved to different locations, and enables concurrent display of 2D and 3D representations at distinct locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual objects are displayed with fixed representations at different locations, then the display is simple, but the adaptability to different use contexts is poor
Solution Approach 1:
The patent implements dynamic representation transformation where virtual objects automatically change their visual form based on detected use contexts. The system transitions from static fixed representations to dynamic adaptive representations that respond to location, device type, and interaction mode changes, resolving the contradiction between simplicity and adaptability.
Solution Approach 2:
The system changes visual parameters such as dimensionality (2D/3D), scale, and rendering style based on detected use contexts. By modifying these parameters dynamically according to the context, the system achieves high adaptability without requiring completely different virtual object models for each scenario.
2Adaptability or versatility
If multiple representations of virtual objects are displayed concurrently, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The patent segments the representation control into independent modules that handle different use contexts separately. Each use context has its own representation rules and parameters, allowing multiple representations to be managed concurrently through modular control rather than a monolithic complex system.
Solution Approach 2:
The system employs a universal representation controller that can generate multiple different representations of the same virtual object based on a single set of context-detection mechanisms. This multi-functional approach allows concurrent display of different representations without proportionally increasing system complexity.
3Ease of operation
If the representation changes based on location use context, then the user interaction is enhanced, but the processing time increases
Solution Approach 1:
The system performs preliminary detection and classification of use contexts continuously in the background, preparing representation transformation parameters in advance. When a context change is detected, the appropriate representation is already prepared or can be quickly generated from pre-defined templates, minimizing the perceived switching time while maintaining high interaction quality.
