Solution Overview
Problem
Existing augmented reality (AR) technologies struggle to naturally fuse virtual content with real space, making it difficult to create immersive and contextually relevant AR experiences.
Innovation Solution
An information processing device and method that utilize a template scene graph to define relative relationships between real and virtual objects, allowing for dynamic content arrangement and interaction based on spatial context and changes within the real space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional AR technology is used to display virtual content, then virtual content can be displayed in real space, but the virtual content cannot be naturally fused with the real space environment
Solution Approach 1:
The system performs preliminary actions by acquiring template data that defines relative relationships between real objects and virtual objects before displaying the augmented reality content. This pre-established template guides the subsequent arrangement of virtual content to ensure natural fusion with the real space environment.
Solution Approach 2:
The system dynamically arranges virtual content based on detected spatial relationships between real objects. The display control unit adjusts the position and orientation of virtual objects in real-time according to the relative relationships detected from three-dimensional data, enabling adaptive integration with the real space environment.
2Ease of manufacture
If virtual content is arranged based on fixed templates, then content arrangement is simplified, but the system cannot adapt to changes in spatial context
Solution Approach 1:
The determination unit continuously detects the relative relationships between real objects from three-dimensional data and provides feedback to the display control unit. This feedback mechanism enables the system to adapt the arrangement of virtual content according to changes in the real space environment while maintaining template-based guidance.
Solution Approach 2:
The template data structure is designed to be universal, defining relative relationships that can accommodate various real objects and virtual content types. This universal template framework allows the system to handle different spatial configurations and object combinations while maintaining ease of content arrangement.
3Measurement precision
If the system detects and processes three-dimensional data in real-time, then spatial context accuracy is improved, but processing complexity increases
Solution Approach 1:
The system segments the processing task by separating the detection of relative relationships between real objects from the arrangement of virtual content. The determination unit focuses on detecting spatial relationships from three-dimensional data, while the display control unit handles the content arrangement based on detected relationships and template data, dividing complexity across functional units.

AI summary
A content display device that functions as an information processing device includes an acquisition unit, a determination unit, and a display control unit. The acquisition unit acquires template data defining relative relationships between a first real object, a second real object, and a virtual object. The determination unit determines the relative relationship between the first real object and the second real object from three-dimensional data of a real space detected by the sensor. The display control unit controls the display device to arrange the virtual object on or near the first real object so as to face the second real object, based on the relative relationships and the template data.
