Solution Overview

Problem

Current virtual reality systems lack an efficient method to differentiate and render virtual objects with physical counterparts from those without in a seamless and intuitive manner, affecting user interaction and immersion.

Innovation Solution

The system employs a virtual reality headset that renders objects in multiple two-dimensional levels, allowing users to view virtual objects with physical counterparts closer and those without on a different level, enabling users to distinguish between them through spatial positioning and user commands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If virtual objects are rendered in a single unified view, then the rendering process is simple, but users cannot clearly distinguish between virtual objects with physical counterparts and those without

Engineering Contradiction:
Improvedistinction between virtual objectsVSAvoidrendering system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments virtual objects into two distinct categories: those with physical counterparts and those without. This segmentation is visually represented by placing objects with physical counterparts on a first 2D level (ground plane) and objects without physical counterparts on a second 2D level (elevated plane), enabling clear visual differentiation while maintaining a unified virtual view.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a vertical dimension (elevation level) to differentiate virtual objects. By rendering objects at different 2D levels within the same virtual space, the system provides additional visual information about object categorization without adding complex multi-view switching mechanisms.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If multiple virtual views are provided to show different object levels, then object differentiation is improved, but user interaction complexity increases

Engineering Contradiction:
Improveobject categorization informationVSAvoiduser interaction simplicity
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent merges the information that would traditionally require separate virtual views into a single unified virtual view. By incorporating vertical level information directly into the spatial arrangement within one view, users can distinguish object categories without needing to switch between multiple views or complex interaction modes.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Instead of creating multiple separate views to show different object categories, the patent uses a vertical dimension within a single view to encode category information. This approach maintains ease of operation by keeping all objects visible in one view while adding dimensional information for differentiation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Use of energy by moving object

If virtual objects are rendered at the same level, then the rendering is computationally efficient, but spatial positioning information is lost

Engineering Contradiction:
Improverendering computational energyVSAvoidspatial positioning information
Core Design Contradiction:
Use of energy by moving objectVSLoss of information

Solution Approach 1:

The patent adds a vertical level dimension to the rendering without significantly increasing computational complexity. By placing objects at different vertical levels (first level for objects with physical counterparts, second level for objects without), the system efficiently communicates spatial positioning and object category information using simple elevation differences rather than complex 3D positioning.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent applies different vertical level qualities to different object categories locally. Objects with physical counterparts are consistently placed at the first level, while objects without physical counterparts are placed at the second level, creating a clear local quality distinction that preserves spatial information without requiring complex rendering for each object.

Inventive Principle:
Principle #3Local quality
