Wave Expression via Attribute Extraction in VR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR technologies can only express wave shapes based on position information, failing to convey characteristics like 'raging' or 'calm' waves, which require additional attributes beyond mere shape.
Innovation Solution
An information processing system that includes a content generation device and method to detect position and attribute information from video images, using Gaussian mixture models and attribute extraction to generate content information that controls video and sound presentations, enabling expression of wave characteristics like calmness, rolling, and power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only position information of objects is used to generate wave shape, then the wave shape can be obtained, but the wave expression (characteristics like raging, calm, rolling) cannot be expressed
Solution Approach 1:
The patent segments the information extraction process into two distinct parts: position information detection (for wave shape) and attribute information extraction (for wave expression). This segmentation allows the system to capture both geometric and expressive characteristics separately, then combine them to overcome the limitation of using only position data.
Solution Approach 2:
The patent transitions from two-dimensional position information (x, y coordinates) to three-dimensional information by adding attribute dimensions (color, motion, texture). This dimensional expansion enables the system to express wave characteristics beyond mere shape, capturing expressions like 'raging' or 'calm' through additional informational layers.
2Adaptability or versatility
If attribute information extraction is added to position detection, then more expressive content can be presented, but the processing complexity increases
Solution Approach 1:
The patent implements a multi-functional information processing system where the same processing framework handles both position detection and attribute extraction. This universal approach allows the system to perform multiple functions (shape generation and expression extraction) using integrated processing modules, reducing the need for separate specialized systems.
Solution Approach 2:
The patent merges the position information detection process with the attribute information extraction process into a unified information generation system. By combining these functions, the system achieves versatile content expression capability while managing processing complexity through integrated architecture rather than separate independent systems.
