See-Through Display Occlusion and Shadowing Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data models, particularly those representing physical and notional environments, struggle to seamlessly integrate sensory properties such as shadows and occlusions, leading to inconsistencies in interactive experiences across combined data models.
Innovation Solution
A method and apparatus that establish a reference position and dynamically interact between physical and notional data models by determining occlusions and sensory properties, allowing for the generation and output of integrated sensory content using see-through or perceive-through displays, ensuring consistent occlusion and shadowing effects across both models.

Engineering Contradiction Analysis
1Reliability
If sensory properties are integrated between physical and notional data models, then the coherence and immersion of virtual/augmented reality experiences is improved, but the complexity of managing multiple data models and their sensory properties increases
Solution Approach 1:
The patent introduces a mediator system that translates sensory properties between physical and notional data models. This intermediary layer handles the conversion and mapping of sensory characteristics (such as shadows, occlusions, lighting) between the two distinct data models, resolving the complexity of direct integration while maintaining coherence in the integrated sensory experience.
Solution Approach 2:
The system creates a universal sensory property framework that can be applied across both physical and notional data models. By establishing common sensory properties and transformation rules that work across different data model types, the system achieves consistent integration without requiring separate handling mechanisms for each model type.
2Reliability
If occlusion and shadowing effects are applied across both data models, then the visual realism and user immersion are improved, but the computational resources and processing time required increase
Solution Approach 1:
The system applies occlusion and shadowing effects selectively and locally rather than globally. By determining which specific regions or objects require these sensory effects based on their spatial relationships and importance to the user experience, the system maintains visual realism in critical areas while avoiding unnecessary computational expenditure in other areas.
Solution Approach 2:
The patent implements partial application of occlusion and shadowing effects, applying them only where necessary to maintain visual realism rather than computing them for all objects and regions. This partial action approach provides sufficient visual fidelity for immersion while significantly reducing the overall computational burden.

AI summary
To integrate a sensory property such as occlusion, shadowing, reflection, etc. among physical and notional (e.g. virtual/augment) visual or other sensory content, providing an appearance of similar occlusion, shadowing, etc. in both models. A reference position, a physical data model representing physical entities, and a notional data model are created or accessed. A first sensory property from either data model is selected. A second sensory property is determined corresponding with the first sensory property, and notional sensory content is generated from the notional data model with the second sensory property applied thereto. The notional sensory content is outputted to the reference position with a see-through display. Consequently, notional entities may appear occluded by physical entities, physical entities may appear to cast shadows from notional light sources, etc.
