Solution Overview
Problem
Current technologies fail to significantly enhance user immersion in virtual reality and augmented reality environments, despite advancements in computer systems and devices, as they lack effective methods for simulating real-world acoustic and lighting conditions within virtual environments.
Innovation Solution
Systems and methods that capture and correlate lighting and acoustic data from the real environment with a virtual environment, using cameras and microphones to simulate real-world conditions, either by integrating virtual elements into the real world or extending virtual elements into the real world, thereby enhancing realism and presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional computer systems use separate control devices and standard rendering techniques, then device complexity remains manageable, but user immersion and realism in virtual reality environments are insufficient
Solution Approach 1:
The patent merges the virtual environment with the real physical environment by integrating virtual objects into the user's actual room space. Virtual objects are positioned and rendered to appear as if they occupy real physical space, allowing interactions between virtual elements and real-world lighting, acoustics, and spatial characteristics. This merging creates a unified immersive experience where the boundary between virtual and real collapses, significantly enhancing user presence and realism.
Solution Approach 2:
The system employs multi-functional sensors (cameras and microphones) that serve dual purposes: capturing real-world environmental data (lighting conditions, acoustic properties, spatial characteristics) and simultaneously serving as interaction interfaces for the virtual environment. These sensors enable the system to adaptively render virtual content that responds to real-world conditions, creating a dynamic immersive experience without requiring separate specialized devices for each function.
2Reliability
If real-world environmental data is captured and processed to simulate virtual properties, then realism and immersion are enhanced, but computational requirements and processing complexity increase
Solution Approach 1:
The system performs preliminary capture and analysis of real-world environmental characteristics (lighting conditions, acoustic properties, spatial geometry) before virtual content is rendered. By pre-processing and storing environmental data, the system avoids repeated heavy computational analysis during runtime, reducing real-time processing requirements while maintaining high realism in virtual environment simulation.
Solution Approach 2:
The system creates simplified computational models (copies) of real-world environmental properties rather than processing complete high-fidelity sensor data. Environmental characteristics such as lighting patterns, acoustic reflections, and spatial relationships are represented as condensed data structures that can be efficiently queried and applied during virtual rendering, significantly reducing computational overhead while preserving realism.
3Reliability
If virtual objects are integrated into the real world with realistic lighting and acoustics, then user presence is improved, but the complexity of modeling and rendering increases
Solution Approach 1:
The system applies different levels of modeling fidelity to different virtual objects and environment regions based on their importance and visibility. High-priority objects that are centrally positioned or actively interacted with receive detailed lighting and acoustic modeling, while peripheral or less important objects use simplified models. This selective approach maintains user presence in critical areas while reducing overall modeling complexity and computational burden.
Solution Approach 2:
The virtual environment modeling system dynamically adjusts the level of detail and computational resources allocated to different objects and regions based on user attention, camera position, and interaction context. As users move or focus on specific objects, the system adapts rendering quality and acoustic simulation depth accordingly, maintaining high user presence where needed while managing modeling complexity through dynamic resource allocation.
