Solution Overview
Problem
Existing AR content authoring requires specialized knowledge in coordinate transformation and CAD, limiting the ability to supply a variety of AR content to the market and restricts end users from enjoying its benefits.
Innovation Solution
An information processing device and method that allows ordinary users to easily author AR content by acquiring an input image, detecting user-designated positions, computing three-dimensional positions and attitudes of virtual objects, and associating them with real objects using a user interface and computation units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If specialized knowledge about coordinate transformation and CAD is required for AR content authoring, then manufacturing precision of virtual object arrangement is improved, but ease of operation deteriorates
Solution Approach 1:
The patent introduces an intermediary system consisting of a camera, processor, and storage device that automatically captures real-world images, computes three-dimensional positions, and associates virtual objects with real objects. This intermediary system handles the complex coordinate transformation and spatial computation tasks, allowing users to simply designate positions on a two-dimensional screen without needing specialized knowledge of coordinate transformation or CAD.
Solution Approach 2:
The patent replaces manual mechanical adjustment methods (requiring specialized knowledge of coordinate transformation) with an automated computational system. The processor automatically computes three-dimensional positions from two-dimensional screen designations, substituting the need for manual coordinate calculation with automated image processing and spatial computation algorithms.
2Manufacturing precision
If expert users with specialized knowledge create AR content, then quality and precision of AR content is improved, but productivity of content creation deteriorates
Solution Approach 1:
The patent enables ordinary users to perform AR content creation independently without requiring expert intervention. The automated system handles complex computations and processing tasks, allowing users to simply designate positions on the screen and have the system automatically generate properly positioned virtual objects. This self-service capability dramatically increases the number of users who can create AR content while maintaining acceptable quality standards.
3Measurement precision
If complex coordinate transformation and CAD knowledge is required, then accuracy of virtual object positioning is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary processing system that automatically handles the complex coordinate transformation and spatial computation. The camera captures real-world images, the processor computes three-dimensional positions from two-dimensional designations, and the storage device stores the associations between virtual and real objects. This intermediary system encapsulates the complexity, presenting users with a simple interface while maintaining accurate positioning through automated computation.
